| 1 | Morphological and Physiological Responses of Plants to Cadmium Toxicity: A Review显示文摘Cadmium(Cd) contamination has posed an increasing challenge to environmental quality and food security. In recent years,phytoremediation has been particularly scrutinized because it is cost-effective and environmentally friendly, especially the use of metal-hyperaccumulating plants to extract or mine heavy metals from polluted soils. Under Cd stress, responses of hyperaccumulator and non-hyperaccumulator plants differ in morphological responses and physiological processes such as photosynthesis and respiration,uptake, transport, and assimilation of minerals and nitrogen, and water uptake and transport, which contribute to their ability to accumulate and detoxify Cd. This review aims to provide a brief overview of the recent progresses in the differential responses of hyperaccumulator and non-accumulator plants to Cd toxicity in terms of growth and physiological processes. Such information might be useful in developing phytoremediation technology for contaminated soils. | HE Shanying YANG Xiaoe Zhenli HE Virupax C.BALIGAR | 2017 | Pedosphere2017，27，3： | 34 |
| 2 | Degradation of chlorpyrifos in laboratory soil and its impact on soil microbial functional diversity显示文摘Degradation of chlorpyrifos at different concentrations in soil and its impact on soil microbial functional diversity were investigated under laboratory condition.The degradation half-live of chlorpyrifos at levels of 4,8,and 12 mg/kg in soil were calculated to be 14.3,16.7,and 18.0 d,respectively.The Biolog study showed that the average well color development(AWCD) in soils was significantly(P < 0.05) inhibited by chlorpyrifos within the first two weeks and thereafter recovered to a similar level as the control.A similar variation in the diversity indices(Simpson index 1/D and McIntosh index U) was observed,but no significant difference among the values of the Shannon-Wiener index H was found in chlorpyrifos-treated soils.With an increasing chlorpyrifos concentration,the half-life of chlorpyrifos was significantly(P 0.05) extended and its inhibitory effect on soil microorganisms was aggravated.It is concluded that chlorpyrifos residues in soil had a temporary or short-term inhibitory effect on soil microbial functional diversity. | FANG Hua YU Yunlong CHU Xiaoqiang WANG Xiuguo YANG Xiaoe YU Jingquan | 2009 | Journal of Environmental Sciences2009，21，3： | 25 |
| 3 | Assessment of sunflower germplasm for phytoremediation of lead-polluted soil and production of seed oil and seed meal for human and animal consumption显示文摘Phytoremediation is a valuable technology for mitigating soil contamination in agricultural lands,but phytoremediation without economic revenue is unfeasible for land owners and farmers.The use of crops with high biomass and bioenergy for phytoremediation is a unique strategy to derive supplementary benefits along with remediation activities.Sunflower(Helianthus annuus L.)is a high-biomass crop that can be used for the phytoremediation of polluted lands with additional advantages(biomass and oil).In this study,40 germplasms of sunflower were screened in field conditions for phytoremediation with the possibility for oil and meal production.The study was carried out to the physiological maturity stage.All studied germplasms mopped up substantial concentrations of Pb,with maximum amounts in shoot>root>seed respectively.The phytoextraction efficiency of the germplasm was assessed in terms of the Transfer factor(TF),Metal removal efficiency(MRE)and Metal extraction ratio(MER).Among all assessed criteria,GP.8585 was found to be most appropriate for restoring moderately Pb-contaminated soil accompanied with providing high biomass and high yield production.The Pb content in the oil of GP.8585 was below the Food safety standard of China,with 59.5% oleic acid and 32.1% linoleic acid.Moreover,amino acid analysis in meal illustrated significant differences among essential and nonessential amino acids.Glutamic acid was found in the highest percentage(22.4%),whereas cysteine in the lowest percentage(1.3%).Therefore,its efficient phytoextraction ability and good quality edible oil and meal production makes GP.8585 the most convenient sunflower germplasm for phytoremediation of moderately Pb-contaminated soil,with fringe benefits to farmers and landowners. | Afsheen Zehra Zulfiqar Ali Sahito Wenbin Tong Lin Tang Yasir Hamid Muhammad Bilal Khan Zarina Ali Beena Naqui Xiaoe Yang | 2020 | Journal of Environmental Sciences2020，32，1： | 10 |

| 5 | Sodium and Potassium Absorption and Distribution in Relation to Growth and Internal Potassium Use Efficiency of K-efficient and -inefficient rice genotypes显示文摘A pot experiment with two rice (Oriza sativa L.) genotypes differing in internal potassium use efficiency (IKUE) was conducted under different sodium (Na) and potassium (K) levels. Adding NaCl at a proper level enhanced rice vegetative growth and increased grain yield and IKUE under low potassium. Addition of higher rate of NaCl had a negative effect on the growth of the K-efficient rice genotype, but did not for the K-inefficient genotype. Under low-K stress, higher NaCl decreased IKUE of the K-efficient rice genotype but increased IKUE for the K-inefficient genotype. At tillering stage and under low-K stress, adding NaCl increased K and Na contents and decreased the ratio of K/Na for both genotypes. At harvesting stage under low-K stress, adding NaCl increased K and Na contents and K/Na ratio for the K-efficient genotype but decreased the K/Na ratio for the K-inefficient genotype. The accumulated Na was mostly deposited in the roots and sheaths. At tillering stage, the K and Na contents and the K/Na ratios in different parts for both genotypes decreased in the following sequence: K+ in sheaths > K+ in blades > K+ in roots; Na+ in roots > Na+ in sheaths > Na+ in blades; and K/Na in sheaths 》 K/Na in roots. The K-efficient genotype had a lower K/Na ratio in roots and sheaths than the K-inefficient genotype under low-K stress. At harvesting stage, K and Na contents in grains were not affected, whereas K/Na ratio in the rice straws was increased for the K-efficient genotype but decreased for the K-inefficient genotype by Na addition. However, this was not the case under K sufficient condition. | LIU JIANXIANG YANG XIAOE NI WUZHONG and YANG YUAI College of Environmental and Resource Sciences, Zhejiang University, Hangzhou, 310029 (China) | 2001 | Pedosphere2001，11，3： | 5 |
| 6 | Chromosome doubling of Sedum alfredii Hance: A novel approach for improving phytoremediation efficiency显示文摘Sedum alfredii Hance is a cadmium(Cd)/zinc(Zn)hyperaccumulator native to China.However,its relatively low biomass restricted the large-scale application for heavy metal contamination remediation.The chromosome set doubling of S.alfredii in vitro was achieved by 0.1%–0.2%(W/V)colchicine treatment.The plant DNA ploidy was analyzed by flow cytometry and chromosome set doubling plants(CSD)were identified based on the obvious different sharp peak.A tissue culture experiment with different Cd treated levels and a field trial with natural polluted mined soil were conducted to study the effects of chromosome doubling on plant biomass and Cd accumulation in shoots.The results suggested that S.alfredii is a mixoploid.Compared with the wild type plants(WT),CSD exhibited typical'gigas'characteristics in morphology including stem thickness,root hair production,number of leaves and size of stoma guard cell.Fresh weight and dry weight of CSD were increased to 1.62–2.03-fold and 2.26–3.25-fold of WT.And Cd content of CSD showed a17.49%–42.82%increase and 59%increase under tissue culture and field condition,accordingly.In addition,the TF and in BCF of CSD were 2.37-and 1.59-fold of WT,respectively.These results proved that it is feasible to promote phytoextraction efficiency of S.alfredii in Cd contaminated soils through chromosomal engineering,which provides a novel approach for hyperaccumulator application in phytoremediation. | Ying Feng Qiong Wang Qian Meng Yongjun Liu Fengshan Pan Sha Luo Yingjie Wu Luyao Ma Xiaoe Yang | 2019 | Journal of Environmental Sciences2019，31，12： | 4 |

| 9 | Effect of elevated CO_2 concentration on photosynthetic characteristics of hyperaccumulator Sedum alfredii under cadmium stress显示文摘The combined effects of elevated CO_2 and cadmium(Cd) on photosynthetic rate,chlorophyll fluorescence and Cd accumulation in hyperaccumulator Sedum alfredii Hance were investigated to predict plant growth under Cd stress with rising atmospheric CO_2 concentration.Both pot and hydroponic experiments were conducted and the plants were grown under ambient(350 μL L^(-1)) or elevated(800 μL L^(-1))CO_2.Elevated CO_2 significantly(P< 0.05) increased Pn(105%-149%),Pn_(max)(38.8%-63.0%) and AQY(20.0%-34.8%) of S.alfredii in all the Cd treatments,but reduced chlorophyll concentration,dark respiration and photorespiration.After 10 days growth in medium with 50μM Cd under elevated CO_2,PSII activities were significantly enhanced(P < 0.05) with Pm,Fv/Fm,Φ(Ⅱ) and qP increased by 66.1%,7.5%,19.5%and 16.4%,respectively,as compared with ambient-grown plants.Total Cd uptake in shoot of S.alfredii grown under elevated CO_2 was increased by 44.1%-48.5%,which was positively correlated with the increase in Pn.These results indicate that elevated CO_2 promoted the growth of 5.alfredii due to increased photosynthetic carbon uptake rate and photosynthetic lightuse efficiency,and showed great potential to improve the phytoextraction of Cd by S.alfredii. | Tingqiang Li Qi Tao Zhenzhen Di Fan Lu Xiaoe Yang | 2015 | Journal of Integrative Plant Biology2015，57，7： | 2 |

| 11 | Formyl tetrahydrofolate deformylase affects hydrogen peroxide accumulation and leaf senescence by regulating the folate status and redox homeostasis in rice显示文摘It is well established that an abnormal tetrahydrofolate(THF)cycle causes the accumulation of hydrogen peroxide(H_(2)O_(2))and leaf senescence,however,the molecular mechanism underlying this relationship remains largely unknown.Here,we reported a novel rice tetrahydrofolate cycle mutant,which exhibited H_(2)O_(2)accumulation and early leaf senescence phenotypes.Map-based cloning revealed that HPA1 encodes a tetrahydrofolate deformylase,and its deficiency led to the accumulation of tetrahydrofolate,5-formyl tetrahydrofolate and 10-formyl tetrahydrofolate,in contrast,a decrease in 5,10-methenyl-tetrahydrofolate.The expression of tetrahydrofolate cycle-associated genes encoding serine hydroxymethyl transferase,glycine decarboxylase and 5-formyl tetrahydrofolate cycloligase was significantly down-regulated.In addition,the accumulation of H_(2)O_(2)in hpa1 was not caused by elevated glycolate oxidation.Proteomics and enzyme activity analyses further revealed that mitochondria oxidative phosphorylation complex I and complex V were differentially expressed in hpa1,which was consistent with the H_(2)O_(2)accumulation in hpa1.In a further feeding assay with exogenous glutathione(GSH),a non-enzymatic antioxidant that consumes H_(2)O_(2),the H_(2)O_(2)accumulation and leaf senescence phenotypes of hpa1 were obviously compensated.Taken together,our findings suggest that the accumulation of H_(2)O_(2)in hpa1 may be mediated by an altered folate status and redox homeostasis,subsequently triggering leaf senescence. | Erhui Xiong Guojun Dong Fei Chen Chen Zhang Shan Li Yanli Zhang Jahidul Islam Shohag Xiaoe Yang Yihua Zhou Qian Qian Limin Wu Yanchun Yu | 2021 | Science China(Life Sciences)2021，64，5： | 1 |
