| 1 | NaCl对水稻谷氨酸合酶和谷氨酸脱氢酶的胁迫作用显示文摘在 Na Cl的胁迫下 ,水稻幼苗根和叶的谷氨酸合酶和谷氨酸脱氢酶的活性随着营养液中的 Na Cl浓度的升高而降低 ;游离 NH+ 4 在叶中积累 ,在根中未见明显变化。与根相比 ,叶对 Na Cl的胁迫作用更为敏感。叶的 NADH- GOGAT和 NADH- GDH活性在 Na Cl胁迫下降低的程度明显大于根。无论是否有 Na Cl存在 ,根的 NADH- GDH活性明显高于叶。 GS/GDH比值分析提示 ,在对照下 ,根中的 NH+ 4 的同化以 GS- GOGAT途径为主 ;而在 Na Cl胁迫下 ,GS- GOGAT途径明显削弱 ,GDH途径在 NH+ 4 的同化中的作用明显加强。无论是否有 Na Cl的存在 ,叶的 NH+ 4 同化途径都是以 GS- GOGAT为主。 | 林清华 李常健 彭进 张楚富 Peng Shaobing Bennett John | 2000 | 武汉植物学研究2000，18，3： | 34 |
| 2 | From Green Super Rice to green agriculture:Reaping the promise of functional genomics research显示文摘Producing sufficient food with finite resources to feed the growing global population while having a smaller impact on the environment has always been a great challenge.Here,we review the concept and practices of Green Super Rice(GSR)that have led to a paradigm shift in goals for crop genetic improvement and models of food production for promoting sustainable agriculture.The momentous achievements and global deliveries of GSR have been fueled by the integration of abundant genetic resources,functional gene discoveries,and innovative breeding techniques with precise gene and whole-genome selection and efficient agronomic management to promote resource-saving,environmentally friendly crop production systems.We also provide perspectives on new horizons in genomic breeding technologies geared toward delivering green and nutritious crop varieties to further enhance the development of green agricul-ture and better nourish the world population. | Sibin Yu Jauhar Ali Shaochuan Zhou Guangjun Ren Huaan Xie Jianlong Xu Xinqiao Yu Fasong Zhou Shaobing Peng Liangyong Ma Dingyang Yuan Zefu Li Dazhou Chen Ruifeng Zheng Zhigang Zhao Chengcai Chu Aiqing You Yu Wei Susong Zhu Qiongyao Gu Guangcun He Shigui Li Guifu Liu Changhua Liu Chaopu Zhang Jinghua Xiao Lijun Luo Zhikang Li Qifa Zhang | 2022 | Molecular Plant2022，15，1： | 6 |
| 3 | Enclosed stigma contributes to higher spikelet fertility for rice(Oryza sativa L.) subjected to heat stress显示文摘With global warming, rice plants may be subjected to heat stress more regularly during the heatsensitive flowering stage, causing spikelet sterility and grain yield loss.Stigma exsertion is considered to increase pollen reception and promote female reproductive success.The aim of this study was to investigate the role of stigma exsertion on spikelet fertility at high temperatures.Five rice cultivars(Liangyoupeijiu, Shanyou 63, Huanghuazhan, Nagina 22, and IR64) with differing degrees of stigma exsertion were cultivated and exposed to high temperature at anthesis.Heat-tolerant cultivars did not always show a high percentage of spikelets with exserted stigmas, and vice versa.Irrespective of the presence of more pollen grains on exserted stigmas, spikelets with exserted stigmas did not show greater spikelet fertility than spikelets with fewer exserted stigmas or hidden stigmas under heat stress.GA3 application augmented the percentage of spikelets with exserted stigmas;however, it did not increase spikelet fertility under heat stress.Spikelet fertility of whole panicles was negatively correlated with the percentage of spikelets with exserted stigmas, but positively with that with hidden stigmas.Viability of the hidden stigmas was less reduced than that of exserted stigmas under heat stress, suggesting that hidden stigmas have an advantage in maintaining viability.Heat stress delayed anther dehiscence and reduced the viabilities of both exserted stigmas and pollens, thereby causing low spikelet fertility.Together, these results suggest that high spikelet fertility does not depend on stigma exsertion and that enclosed stigma generally contributes to higher spikelet fertility and heat tolerance under high-temperature conditions during flowering in rice. | Chao Wu Kehui Cui Qiuqian Hu Wencheng Wang Lixiao Nie Jianliang Huang Shaobing Peng | 2019 | The Crop Journal2019，7，3： | 4 |
| 4 | Changes of Levels of Glutamine Synthetase Isoforms in Roots and Leaves in Responseto Nitrogen Fertilizer Application at Different Growth Stages in Irrigated Rice显示文摘Nitrogen is a key element to control the growth and yield of crops. Fertilizer urea nitrogen(N)60,45,and 30 kg/hm2 was applied at three different stages, midtillering, panicle initiation, and flowering,of the growth and development of rice plants. respectively. At both midtillering and panicle initiation, the total activity of glutamine synthetase (GS) in rice roots and leaves ovas increased remarkably as a result of a large amount of ammonia absorbed by roots. Native-PAGE and activity staining showed that the increase of total activity in rice roots and leaves was due to the synthesis of GSrb in roots and GSZ in leaves and that the activity of GSra in roots and GSI in leaves remained constant. The results shoaled that the assimilation of external nitrogen was carried out by GSrb but not GSra in rice roots and that the activitry. of GS2 ovas induced also by the external nitrogen, and that GSrb played main role in meeting the needs of the rapid tillering for nitrogen. At flowering, the activity of GS in rice roots and leaves did not change almost after topdressing.These rssults suggest that the change of GS activity in rice roots may use as a measure of the utilization efficiency of the fertilizer. | Zhang Chufu Peng Shaobing John Bennett | 1998 | Wuhan University Journal of Natural Sciences1998，3，4： | 4 |
| 5 | Comparison of yield performance between direct-seeded and transplanted double-season rice using ultrashort-duration varieties in central China显示文摘Labor scarcity requires double-season rice to be planted by direct seeding as an alternative to transplanting. Only ultrashort-duration varieties can be used in direct-seeded, double-season rice(DSD) in central China where thermal time is limited. Whether ultrashort-duration varieties grown in DSD can be as productive and efficient in nitrogen(N) use as transplanted double-season rice(TPD) remains unclear. Field experiments were conducted in Hubei province, central China with two establishment methods(DSD,TPD) and three N rates in the early and late seasons of 2017 and 2018. Nitrogen treatments included zero-N control(N0), total N rate of 60 kg N ha;with equal splits at basal, midtillering, and panicle initiation(N1), and weekly N application at 15 kg ha;from seeding/transplanting to heading(N2). Both early-and late-season rice under DSD matured within 95 days, on average 9 days shorter than rice under TPD. The grain yield of DSD was comparable to or higher than that of TDP in both seasons, although the daily yield was significantly higher under DSD than under TDP. Before heading, DSD had higher leaf area,stem number, intercepted radiation, and radiation use efficiency than TPD, which compensated for the negative effect of short growth duration on biomass production. Total dry weight and harvest index under DSD were comparable to or higher than those under TDP. In general, the recovery efficiency of fertilizer-N under DSD was higher than that under TPD, but the reverse was true for physiological N use efficiency. Thus, there was no significant difference in agronomic N use efficiency between DSD and TPD. These results suggested that DSD with ultrashort-duration varieties is a promising alternative to TPD in central China for maintaining high grain yield and N fertilizer use efficiency with less labor input. | Le Xu Shen Yuan Xinyu Wang Zhifeng Chen Xiaoxiao Li Jing Cao Fei Wang Jianliang Huang Shaobing Peng | 2022 | The Crop Journal2022，10，2： | 4 |
| 6 | Heavy soil drying during mid-to-late grain filling stage of the main crop to reduce yield loss of the ratoon crop in a mechanized rice ratooning system显示文摘Yield loss(Y_(Loss)) in the ratoon crop due to crushing damage to left stubble from mechanical harvesting of the main crop is a constraint for wide adoption of mechanized rice ratooning technology.Soil drying before the harvest of the main crop has been proposed to overcome this problem.The objective of this study was to determine the effect of soil drying during the mid-to-late grain filling stage of the main crop on grain yield of the ratoon crop in a mechanized rice ratooning system.Field experiments were conducted to compare Y_(Loss) between light(LD) and heavy(HD) soil drying treatments in Hubei province,central China in 2017 and 2018.Y_(Loss) was calculated as the percentage of yield reduction in the ratoon crop with the main crop harvested mechanically,relative to the grain yield of the ratoon crop with the main crop harvested manually.In comparison with LD,soil hardness was increased by 42.8%-84.7% in HD at the 5-20 cm soil depth at maturity of the main crop.Soil hardness at 5 and 10 cm depths reached respectively 4.05 and 7.07 kg cm^(-2) in HD.Soil drying treatment did not significantly affect the grain yield of the main crop.Under mechanical harvesting of the main crop,HD increased the grain yield of the ratoon crop by 9.4% relative to LD.Consequently,Y_(Loss) was only 3.4% in HD,in contrast to 16.3% in LD.The differences in grain yield and Y_(Loos) between the two soil drying treatments were explained mainly by panicles m^(-2),which was increased significantly by HD in the track zone of the ratoon crop compared with LD.These results suggest that heavy soil drying practice during the mid-to-late grain filling stage of the main crop is effective for reducing Y_(Loss) of the ratoon crop in a mechanized rice ratooning system. | Chang Zheng Yuechao Wang Shen Yuan Sen Xiao Yating Sun Jianliang Huang Shaobing Peng | 2022 | The Crop Journal2022，10，1： | 3 |
