| 1 | Genetic analysis and gene mapping of a dominant presenescing leaf gene PSL3 in rice (Oryza sativa L.)显示文摘Leaf senescence as an active process is essential for plant survival and reproduction.However,premature senility is harmful to agricultural production.In this study,a rice mutant,named as psl3 (presescing leaf 3) isolated from EMS-treated Jinhui 10,displays obvious premature senility features both in morphological and physiological level.Genetic analysis showed that mutant trait was controlled by a single dominant gene (PSL3),which was located on rice chromosome 7 between SSR marker c7sr1 and InDel marker ID10 with an interval of 53.5 kb.The result may be useful for the isolation of the PSL3 gene. | FANG LiKui LI YunFeng GONG XiaoPing SANG XianChun LING YingHua WANG XiaoWen CONG YunFei HE GuangHua | 2010 | Chinese Science Bulletin2010，55，23： | 20 |
| 2 | Boosting proso millet yield by altering canopy light distribution in proso millet/mung bean intercropping systems显示文摘To elucidate the mechanism by which intercropping proso millet(Panicum miliaceum L.)with mung bean(Vigna radiata L.)increases proso millet yield and to determine how this higher yield results from maximization of resources use efficiency,we designed and conducted four strip intercropping row arrangements,including two rows of proso millet alternating with two rows of mung bean(2P2M),four rows of proso millet alternating with two rows of mung bean(4P2M),four rows of proso millet alternating with four rows of mung bean(4P4M),two rows of proso millet alternating with four rows of mung bean(2P4M),sole proso millet(SP,control)and sole mung bean(SM,control)in Yulin,Shaanxi,China.Photosynthetically active radiation(PAR)in the canopy,radiation use efficiency(RUE),leaf photosynthetic characteristics,dry matter accumulation and allocation,and yield of proso millet were investigated.The results showed that the intercropping systems had higher PAR than the monoculture.Mean PAR intensities were increased by respectively 2.2%–23.4%,19.8%–59.7%,and 61.2%–133.3%in the proso millet upper,middle and lower canopies compared with SP.The increase in PAR directly increased RUE,a result attributed mainly to the increase in photosynthetic capacity,including net photosynthetic rate and chlorophyll content.These responses resulted in increased dry matter allocation to plant organs.Yield of intercropped proso millet was 6.8%–37.3%higher than that under monoculture and the land equivalent ratios for the different intercropping patterns were all greater than unity(>1).In general,yield followed a positive linear function of PAR in the intercropping system.The results indicated that intercropping can boost proso millet yield,evidently by altering light distribution within its canopy and consequently increasing RUE,thereby increasing leaf photosynthetic capacity,dry matter accumulation,and allocation to the grain.The optimum combination for improving the growth and yield of proso millet on the Loess Plateau of China was 2P4M. | Xiangwei Gong Uzizerimana Ferdinand Ke Dang Jing Li Guanghua Chen Yan Luo Pu Yang Baili Feng | 2020 | The Crop Journal2020，8，2： | 6 |
| 3 | The general transcriptional repressor Tup1 governs filamentous development in Candida tropicalis显示文摘Filamentous development is associated with the ability to cause infections and colonize the host in pathogenic Candida species.Candida tropicalis is one of the major fungal pathogens of humans.The conserved transcriptional repressor Tup1 plays a critical role in the regulation of transcription and filamentation in yeast species.Despite its central role,the full coding sequence of TUP1 has not been found in the reported genome sequence of C.tropicalis to date.In this study,we report the identification of Tup1 and characterize its role in filamentous growth in C.tropicalis.As expected,C.tropicalis Tup1 exhibits general conserved features to the orthologs of other fungi in terms of its structure and function.Deletion of TUP1 in C.tropicalis leads to increased filamentation under several culture conditions.However,Tup1 indeed exhibits species-specific roles in the regulation of filamentous development in C.tropicalis.For example,unlike the tup1/tup1 mutant of Candida albicans,the tup1/tup1 mutant of C.tropicalis is able to exist in the yeast form at low temperatures or in the presence of N-acetylglucosamine(GlcNAc).Acidic pH conditions also favor the yeast form of the tup1/tup1 mutant of C.tropicalis.Quantitative real-time PCR(qRT-PCR)assays indicate that Tup1 may regulate filamentous development through the transcriptional control of key filamentation regulators in C.tropicalis,such as Ume6,Brg1,Wor1,Sfl2,Ahr1,and Zcf3.Taken together,our findings demonstrate both conserved and species-specific roles of Tup1 in the regulation of filamentation and provide novel insights into the biology of C.tropicalis. | Jiao Gong Qian Huang Weihong Liang Yujia Wei Guanghua Huang | 2019 | Acta Biochimica et Biophysica Sinica2019，51，5： | 1 |
| 6 | Optimal Taxation in an Endogenous Growth Model with Multiple Levels of Governments显示文摘This paper presents a framework with federal income tax, federal transfer, and local taxes in an dynamic growth model with multiple levels of governments and public capital formation. It derives the rate of endogenous growth and, with both simulations and special examples, examines how the rate of endogenous growth changes with respect to federal income tax, local taxes, and federal transfers. | Chen Zhong Gong Liutang Zou Hengfu( School of Science of Jianghan Petroleum Institute, Wuhan 434023 Guanghua School of Management of Peking University, Beijing 100871 Institute for A dvanced Study of Wuhan University, Wuhan 430072) | 2002 | Science Foundation in China2002，10，2： | 1 |
