| 1 | Effects of herbivore-induced rice volatiles on the host selection behavior of brown planthopper,Nilaparvata lugens显示文摘It has been suggested that herbivore would react to volatiles produced by herbivore infested plant due to potential change, either positive or negative, in the acceptability of the host plant. This hypothesis was tested for the brown planthopper (BPH) in the laboratory. Sixteen components of the headspace volatiles from rice seedlings with different treatments were collected with SPME and Tenax-TA trap and analyzed with GC and GC-MS. Significant differences in volatile emissions were observed for rice plants with different treatments. Undamaged control plants, mechanically damaged plants and the plants infested by BPH for 1 or 2 d emitted much lower amounts of volatiles compared to the plants infested by BPH for 3 or 5 d. The plants infested by BPH for 3 or 5 d emitted several volatiles that were not detected in undamaged control plants, mechanically damaged plants or the plants infested by BPH for 1 or 2 d. Spodoptera litura infested plants released much higher amounts of volatiles than those in all | XU Tao ZHOU Qiang XIA Qiang ZHANG Wenqing ZHANG Guren GU Dexiang | 2002 | Chinese Science Bulletin2002，47，16： | 13 |
| 2 | Apoptosis of Spodoptera litura larval hemocytes induced byheavy metal zinc显示文摘By adding different amount of zinc into the artificial medium of the insect larvae, the zinc-induced apoptosis of the larvae haemocytes of the herbivorous insect Spodoptera litura Fabricius was investigated with flow cy- tometer. The results showed that the increase of zinc dose in the artificial feed led to the accumulations of zinc in the lar- val hemolymph and fat body, and more zinc was accumu- lated in fat body than in hemolymph. The apoptosis of hemocytes was significantly induced at high zinc concentra- tion (1000 mg·kg?1) in the insect diet, and the apoptosis rate was 63.63%, which was remarkably higher than that at con- trol and lower concentrations (50―500 mg·kg?1). This sug- gests that the high dose of zinc in the artificial diet of S. litura larvae could induce the apoptosis of the larval hemocytes of S. litura. | XIA Qiang SUN Hongxia HU Xinjun SHU Yinghua GU Dexiang ZHANG Guren | 2005 | Chinese Science Bulletin2005，50，24： | 9 |
| 3 | Temperature and substrate availability regulate soil respiration in the tropical mountain rainforests,Hainan Island,China显示文摘Aims Tropical forest plays a key role in global C cycle;however,there are few studies on the C budget in the tropical rainforests in Asia.This study aims to(i)reveal the seasonal patterns of total soil respiration(R_(T)),litter respiration(R_(L))and soil respiration without surface organic litter(R_(NL))in the primary and secondary Asian tropical mountain rainforests and(ii)quantify the effects of soil temperature,soil moisture and substrate availability on soil respiration.Methods The seasonal dynamics of soil CO_(2) efflux was measured by an automatic chamber system(Li-8100),within the primary and secondary tropical mountain rainforests located at the Jianfengling National Reserve in Hainan Island,China.The litter removal treatment was used to assess the contribution of litter to belowground CO_(2) production.Important Findings The annual R_(T) was higher in the primary forest(16.73±0.87 Mg C ha−1)than in the secondary forest(15.10±0.26 Mg C ha−1).The rates of R_(T),R_(NL) and R_(L) were all significantly higher in the hot and wet season(May–October)than those in the cool and dry season(November–April).Soil temperature at 5cm depth could explain 55–61%of the seasonal variation in R_(T),and the temperature sensitivity index(Q_(10))ranked by R_(L)(Q_(10)=3.39)>R_(T)(2.17)>R_(NL)(1.76)in the primary forest and by R_(L)(4.31)>R_(T)(1.86)>R_(NL)(1.58)in the secondary forest.The contribution of R_(L) to R_(T) was 22–23%,while litter input and R_(T) had 1 month time lag.In addition,the seasonal variation of R_(T) was mainly determined by soil temperature and substrate availability.Our findings suggested that global warming and increased substrate availability are likely to cause considerable losses of soil C in the tropical forests. | Zhang Zhou Lai Jiang Enzai Du Huifeng Hu Yide Li Dexiang Chen Jingyun Fang | 2013 | Journal of Plant Ecology2013，6，5： | 8 |
| 4 | Total phenolic, flavonoid content, and antioxidant activity of flour, noodles, and steamed bread made from different colored wheat grains by three milling methods显示文摘The objective of this study was to evaluate the effects of wheat variety, food processing, and milling method on antioxidant properties. Black wheat variety Heibaoshi 1 had the highest total phenolic content(659.8 μg gallic acid equivalents g-1), total flavonoid content(319.3 μg rutin equivalents g-1), and antioxidant activity, whereas light purple wheat variety Shandongzimai 1 had the lowest total flavonoid content(236.2 μg rutin equivalents g-1) and antioxidant activity. Whole wheat flour and partially debranned grain flour had significantly higher total phenolic contents, total flavonoid contents, and antioxidant activity than refined flour(P < 0.05). Compared with flour, total phenolic contents, total flavonoid contents and antioxidant activity decreased in noodles and steamed bread, whereas noodles had slightly higher total phenolic and flavonoid content than steamed bread. Antioxidant activities(by ferric reducing ability of plasma assay) of steamed bread made from whole wheat flour, partially debranned grain flour, and refined flour were 23.5%, 21.1%, and 31.6% lower, respectively, than the corresponding values of flour. These results suggested that black whole wheat flour and partially debranned grain flour are beneficial to human health. | Yaoguang Li Dongyun Ma Dexiang Sun Chenyang Wang Jian Zhang Yingxin Xie Tiancai Guo | 2015 | The Crop Journal2015，3，4： | 7 |
| 5 | Feed conversion ratio,residual feed intake and cholecystokinin type A receptor gene polymorphisms are associated with feed intake and average daily gain in a Chinese local chicken population显示文摘Background: The feed conversion ratio(FCR) and residual feed intake(RFI) are common indexes in measuring feed efficiency for livestock. RFI is a feed intake adjusted for requirements for maintenance and production so these two traits are related. Similarly, FCR is related to feed intake and weight gain because it is their ratio. Cholecystokinin type A receptor(CCKAR) plays an important role in animal digestive process. We examined the interplay of these three parameters in a local Chinese chicken population.Results: The feed intake(FI) and body weights(BW) of 1,841 individuals were monitored on a daily basis from 56 to 105 d of age. There was a strong correlation between RFI and average daily feed intake(ADFI) and a negative correlation between the FCR and daily gain(r_g=-0.710). Furthermore, we identified 51 single nucleotide polymorphisms(SNPs) in the CCKAR and 4 of these resulted in amino acid mutations. The C334A mutation was specifically associated with FI and the expected feed intake(EFI)(P < 0.01) and significantly associated with the average daily gain(ADG)(P < 0.05). G1290A was significantly associated with FI and EFI(P < 0.05).Conclusion: FCR is apply to weight selecting, and RFI is more appropriate if the breeding focus is feed intake. And C334A and G1290A of the CCKAR gene can be deemed as candidate markers for feed intake and weight gain. | Zhenhua Yi Xing Li Wen Luo Zhenqiang Xu Congliang Ji Yan Zhang Qinghua Nie Dexiang Zhang Xiquan Zhang | 2018 | Journal of Animal Science and Biotechnology2018，9，4： | 7 |
| 6 | Fabric Defect Detection Using Independent Component Analysis and Phase Congruency显示文摘A novel method based on independent component analysis and phase congruency is proposed for detecting defects in textile fabric images. By independent component, we can obtain textile structural features of fabric-free images. By phase congruency, structure information is reduced, which can distinguish the defect region from the defect-free regions. Finally, we have the detecting result from binary image which is obtained by a threshold step. Compared with other algorithms, the proposed method not only has robustness with high detection rate, but also detects various types of defects quite well. | LENG Qiujun ZHANG Hu FAN Cien DENG Dexiang | 2014 | Wuhan University Journal of Natural Sciences2014，19，4： | 7 |
| 7 | Involvement of Jasmonate- signaling pathway in the herbivore-induced rice plant defense显示文摘The expression patterns of eight defense- related genes in the herbivore-infested and jasmonate- treated (jasmonic acid, JA and its derivative MeJA) rice leaves were analyzed using RT-PCR. The results showed that Spodoptera litura Fabricius (Lepidoptera: Noctuidae) herbi-vory induced the expression of lipoxygenase (LOX) and al-lene oxide synthase (AOS) genes that are involved in the jasmonate-signaling pathway. Moreover, S. litura damage resulted in the expression of farnesyl pyrophosphate syn-thase (FPS), Bowman-birk proteinase inhibitor (BBPI), phenylalanine ammonia-lyase (PAL) and other rice defense- related genes that were also induced by aqueous JA treat-ment or gaseous MeJA treatment. These indicated that in rice leaves, the JA-related signaling pathway was involved in the S. litura-induced chemical defense. Mechanical damage and brown planthopper (BPH), Nilaparvata lugens (St錶) (Homoptera: Delphacidae) damage induced the expression of LOX gene, but both treatments did not induce the expression of AOS gene. However, BPH damage induced the expression of acidic pathogen-related protein 1 (PR-1a), Chitinase (PR-3), and PAL genes, which is involved in the salicylate- signaling pathway. It was suggested that salicylate-related signaling pathway or other pathways, rather than jas-monate-signaling pathway was involved in the BPH-induced rice plant defense. | XU Tao ZHOU Qiang CHEN Wei ZHANG Guren HE Guofeng GU Dexiang ZHANG Wenqing | 2003 | Chinese Science Bulletin2003，48，18： | 6 |
| 8 | Effects of polygonatum sibiricum polysaccharide on learning and memory in a scopolamine-induced mouse model of dementia显示文摘BACKGROUND: Learning and memory processes are accompanied by complex neuropathological and biochemical changes. Free radicals play an important role in learning and memory damage. OBJECTIVE: To observe the effects of polygonatum sibiricum polysaccharide (PSP) in comparison with vitamin E on inhibiting free radical damage, as well as improving the degree of cerebral ischemia and learning and memory in a scopolamine-induced mouse model of dementia. DESIGN: Randomized controlled animal study. SETTINGS: Department of Pharmacology, Taishan Medical College; Shandong Jewim Pharmaceutical Co., Ltd. MATERIALS: A total of 105 healthy Kunming mice, comprising 90 males and 15 females that were clean grade, were provided by the Animal Center of Taishan Medical College. PSP (extracted and purified by Huangjing, Taishan) was provided by the Department of Traditional Chinese Medicine, Taishan Medical College (purity of 79.6% by using a phenol-concentrated sulphate acid method), and hydrogen bromine acid scopolamine injection solution (SCO) by Shanghai Hefeng Pharmaceutical Co., Ltd. METHODS: This study was performed at the Pharmacological Laboratory of Taishan Medical College from March to June 2007. ① A total of 75 healthy Kunming male mice of clean grade were randomly divided into a normal control group, positive control group, and low-dosage and high-dosage PSP groups, with 15 mice in each group. Mice in both the low-dosage and high-dosage PSP groups were intragastrically administered 0.5 g/kg and 2.0 g/kg PSP, respectively. Mice in the positive control group were intragastrically administered 0.5 g/kg vitamin E. In addition, mice in both the normal control group and model group were intragastrically administered the same volume of saline, respectively, once a day for 7 consecutive days. One hour after the final administration on day 6, mice in the positive control group, model group, low-dosage and high-dosage PSP groups were subcutaneously injected with 3.0 mg/kg SCO, while mice in the normal control group were subcutaneously injected with the same volume of distilled water. Ten minutes later, the step test was employed to measure memory. The training was performed 5 times, with 30-minute intervals between 2 sets. If the mice remained on the platform (latent period) for 30 minutes, they were determined to have learned the task. An eligible percentage was then recorded. Twenty-four hours later, the number of error responses from each mouse was recorded in a 5-minute period, based on the above-mentioned parameters. Mice were sacrificed under anesthesia. The activities of glutathione hyperoxide enzyme (GSH-Px), superoxide dismutase (SOD), and the content of malondialdehyde (MDA) were assayed using an UV spectrophotometer. ② The remaining 30 healthy Kunming mice of both genders were randomly divided into 3 groups, including control group, low-dosage PSP group, and high-dosage PSP group, with 10 mice in each group. Mice in both the low-dosage and high-dosage PSP groups were intragastrically administered 0.5 g/kg and 2.0 g/kg PSP, respectively, while the mice in the control group were perfused with the same volume of saline. Forty minutes later, the mice under superficial anesthesia were decapitated, and the number and duration of mouth-opening breaths of the isolated mouse head were immediately recorded. MAIN OUTCOME MEASURE: ① Numbers of error responses within 5 minutes on the platform. ② GSH-Px and SOD activity, as well as MDA content in mouse brain tissue. ③ Numbers and duration of mouth-opening breaths of the isolated mouse head. RESULTS: Of the 105 Kunming experimental mice, two mice died due to electric shock during the step-down test, therefore, a total of 103 mice were involved in the final analysis. ① Effects of PSP on learning in mice: The eligible percentage in the high-dosage PSP group was higher than the control group at the 3rd and 5th training sessions (P < 0.05). ② Effects of PSP on memory in mice: The number of errors in the step-down test in the model group was higher than in the normal control group (P < 0.01). Compared tothe model group, the number of errors in the step-down test was lower in both the low-dosage and high-dosage PSP groups (P < 0.01). ③ Effects of PSP on amount of GSH-Px, SOD, and MDA in mouse brain tissue: SOD and GSH-Px activity was higher in both the low-dosage and high-dosage PSP groups than in the model group. MDA content was lower in the high-dosage PSP group, compared to the model group. GSH-Px activity in the brain tissue of the high-dosage PSP group was similar to the positive control group (P > 0.05). ④ Effects of PSP on acute cerebral ischemia in mice: The low-dosage PSP, and in particular the high-dosage PSP, prolonged the number and duration of mouth-opening breaths of the isolated mouse head (P < 0.05, 0.01). CONCLUSION: PSP can improve learning and memory in a scopolamine-induced mouse model of dementia by reducing the damaging effects of cerebral ischemia and anti-oxidation. In addition, the effects are dose-dependent and are similar to those provided by vitamin E. | Feng Zhang Jiguo Zhang Lihua Wang Dexiang Mao | 2008 | Neural Regeneration Research2008，3，1： | 6 |
| 9 | Ice-wedge Pseudomorphs Showing Climatic Change Since the Late Pleistocene in the Source Area of the Yellow River, Northeast Tibet显示文摘The source area of the Yellow River is located in the northeastern Tibetan Plateau, and is a high-elevation region with the annual mean temperature of-3.9℃. The ice-wedge pseudomorphs discovered in this region are recognized as two types.One was found in sandy gravel beds of the second terrace of the Yellow River. This ice-wedge pseudomorph is characterized by higher ratio of breadth/depth, and are 1~1.4 m wide and about 1 m deep. The bottom border of the ice-wedge pseudomorph is round arc in section. Another discovered in the pedestal of the second terrace has lower ratio of width/depth, and is 0.3~1.0 m wide and 1~2 m deep. Its bottom border is sharp. Based on the TL dating, the former was formed at the middle Holocene (5.69±0.43 ka BP and 5.43±0.41 ka BP),that is, the Megathermal, and the latter was formed at the late Last Glacial Maximum (13.49± 1.43 ka BP).Additionally, the thawing-freezing folders discovered in the late Late Pleistocene proluvium are 39.83±3.84 ka BP in age. The study on the ice-wedge pseudomorphs showed that the air temperature was lowered by up to 6~7 ℃ in the source area of the Yellow River when the ice-wedge pseudomorphs and thawing-freezing folds developed. | CHENG Jie ZHANG Xujiao TIAN Mingzhong YU Wenyang YU Jiangkuan TANG Dexiang YUE Jianwei | 2005 | Journal of Mountain Science2005，2，3： | 3 |

| 16 | Rodent-mediated plant community competition:what happens to the seeds after entering the adjacent stands?显示文摘Background:Seed dispersal by scatter-hoarding animals can affect the developmental dynamics of plant communities.However,how animals might participate in plant inter-community competition has rarely been investigated.Forest community junction is an area where the competition between plant communities is most prominent and animal activity is more frequent.At present,little is known about how scatter-hoarding animals might assist competitions by adjacent plant communities.Thus,for 3 years(2015–2017),we tracked the fate of 2880 tagged seeds(Quercus aliena var.acuteserrata,Pinus tabuliformis,and P.armandii seed)placed near an edge where the forest composition changes from a pine forest to an oak forest in northwestern China.Results:We found that the seed fates differed when Quercus and Pinus seeds entered adjacent stands.In contrast to Pinus seeds,acorns that entered pine forests were characterized by higher caching rates and longer dispersal distances.Pinus seeds had the highest probability of being predated(85%)by rodents,and eleven Q.aliena var.acuteserrata seedlings were established in pine forests,although none survived in the later stages.In addition,rodents exhibited obvious selectivity in terms of the microhabitats for the seed caching sites.Conclusions:Seed fates differed when Quercus and Pinus seeds entered adjacent stands.The predation pressure by rodents on the seeds of Pinus species limited the germination of seeds and seedling establishment in oak forests.The different seed fates after their bidirectional dispersal could affect the differences in natural regeneration between pine and oak forests,and they might increase the recruitment rates for oak at the edge of an adjacent community.Rodent-mediated seed dispersal could potential unintentionally affect the competition between plant communities. | Haibin Kang Mingjie Chang Shutong Liu Zhi Chao Xinping Zhang Dexiang Wang | 2020 | Forest Ecosystems2020，7，4： | 1 |

| 18 | Region-of-interest micro-focus computed tomography based on an all-optical inverse Compton scattering source显示文摘Micro-focus computed tomography(CT),which allows the hyperfine structure within objects to be reconstructed,is a powerful nondestructive testing tool in many fields.However,current x-ray sources for micro-focus CT are typically limited by their relatively low photon energy and low flux.An all-optical inverse Compton scattering source(AOCS)based on laser wakefield acceleration can generate intense quasi-monoenergetic x/gamma-ray pulses in the kilo-to megaelectronvolt range with micrometer-level source size,and its potential application for micro-focus CT has become very attractive in recent years because of the rapid progress made in laser wakefield acceleration.Reported here is a successful experimental demonstration of high-fidelity micro-focus CT using an AOCS(∼70 keV)by imaging and reconstructing a test object with complex inner structures.A region-of-interest CT method is adopted to utilize the relatively small field of view of the AOCS to ensure high spatial resolution.This demonstration of AOCS-based region-of-interest micro-focus CT is a key step toward its application in the field of hyperfine nondestructive testing. | Yue Ma Jianfei Hua Dexiang Liu Yunxiao He Tianliang Zhang Jiucheng Chen Fan Yang Xiaonan Ning Zhongshan Yang Jie Zhang Chih-Hao Pai Yuqiu Gu Wei Lu | 2020 | Matter and Radiation at Extremes2020，5，6： | 1 |
