Zhengfu Yang, Lianping Sun, Peipei Zhang, Yingxin Zhang, more

The Plant Journal > 99 > 5 > 844 - 861

Male reproductive development involves a complex series of biological events and precise transcriptional regulation is essential for this biological process in flowering plants. Several transcriptional factors have been reported to regulate tapetum and pollen development, however the transcriptional mechanism underlying Ubisch bodies and pollen wall formation remains less understood. Here, we characterized...

LSSR1 facilitates seed setting rate by promoting fertilization in rice

Xiaojiao Xiang, Peipei Zhang, Ping Yu, Yingxin Zhang, more

Rice > 2019 > 12 > 1 > 1-14

Seed setting rate is one of the major components that determine rice (Oryza sativa L.) yield. Successful fertilization is necessary for normal seed setting. However, little is known about the molecular mechanisms governing this process. In this study, we report a novel rice gene, LOW SEED SETTING RATE1 (LSSR1), which regulates the seed setting rate by facilitating rice fertilization. LSSR1 encodes...

Galal Bakr Anis, Yingxin Zhang, Anowerul Islam, Yue Zhang, more

BMC Plant Biology > 2019 > 19 > 1 > 1-13

Background Nitrogen (N) is a major input cost in rice production, in addition to causing severe pollution to agricultural and ecological environments. Root dry weight has been considered the most important component related to crop yields than the other root traits. Therefore, development of rice varieties/lines with low input of N fertilizer and higher root traits are essential for sustainable rice...

OsMS1 functions as a transcriptional activator to regulate programmed tapetum development and pollen exine formation in rice

Zhengfu Yang, Ling Liu, Lianping Sun, Ping Yu, more

Plant Molecular Biology > 2019 > 99 > 1-2 > 175-191

Key message OsMS1 functions as a transcriptional activator and interacts with known tapetal regulatory factors through its plant homeodomain (PHD) regulating tapetal programmed cell death (PCD) and pollen exine formation in rice. Abstract The tapetum, a hallmark tissue in the stamen, undergoes degradation triggered by PCD during post-meiotic anther development. This degradation process is indispensable...

Yongbo Hong, Yingxin Zhang, Sittipun Sinumporn, Ning Yu, more

The Plant Journal > 95 > 5 > 877 - 891

Premature leaf senescence in rice is one of the most common factors affecting the plant's development and yield. Although methyltransferases are involved in diverse biological functions, their roles in rice leaf senescence have not been previously reported. In this study, we identified the premature leaf senescence 3 (pls3) mutant in rice, which led to early leaf senescence and early heading date...

The rice CONSTANS-like protein OsCOL15 suppresses flowering by promoting Ghd7 and repressing RID1

Weixun Wu, Yingxin Zhang, Miao Zhang, Xiaodeng Zhan, more

Biochemical and Biophysical Research Communications > 2018 > 495 > 1 > 1349-1355

The photoperiodic flowering pathway is one of the most important regulatory networks controlling flowering time in rice (Oryza sativa L.). Rice is a facultative short-day (SD) plant; flowering is promoted under inductive SD conditions and delayed under non-inductive long-day (LD) conditions. In rice, flowering inhibitor genes play an important role in maintaining the trade-off between reproduction...

Plant Growth Regulation > 2018 > 84 > 1 > 123-133

Phosphate (Pi) plays important roles in plant development and architecture. With the goal of identifying genomic regions that influence tolerance to Pi deficiency (TPDE) in hybrid rice (Oryza sativa L.), quantitative trait loci (QTL) were mapped using recombinant inbred lines (RILs) that were derived from a cross between tolerant ‘XieqingzaoB’ (XB) and susceptible ‘Zhonghui9308’. Six TPDE-related...

OsCOL16, encoding a CONSTANS-like protein, represses flowering by up-regulating Ghd7 expression in rice

Weixun Wu, Xiao-Ming Zheng, Daibo Chen, Yingxin Zhang, more

Plant Science > 2017 > 260 > C > 60-69

Flowering time is an important agronomic trait that coordinates the plant life cycle with regional adaptability and thereby impacts yield potentials for cereal crops. The CONSTANS (CO)-like gene family plays vital roles in the regulation of flowering time. CO-like proteins are typically divided into four phylogenetic groups in rice. Several genes from groups I, III, and IV have been functionally characterized,...

ES7, encoding a ferredoxin-dependent glutamate synthase, functions in nitrogen metabolism and impacts leaf senescence in rice

Zhenzhen Bi, Yingxin Zhang, Weixun Wu, Xiaodeng Zhan, more

Plant Science > 2017 > 259 > C > 24-34

Glutamate synthase (GOGAT) is a key enzyme for nitrogen metabolism and ammonium assimilation in plants. In this study, an early senescence 7 (es7) mutant was identified and characterized. The leaves of the es7 mutant begin to senesce at the tillering stage about 60day after sowing, and become increasingly senescent as the plants develop at the heading stage. When es7 plants are grown under photorespiration-suppressed...

Xiaodeng Zhan, Bin Sun, Zechuan Lin, Zhiqiang Gao, more

Gene > 2015 > 571 > 2 > 263-270

Source size, sink size and heading date (HD) are three important classes of traits that determine the productivity of rice. In this study, a set of recombinant inbred lines (RILs) derived from the cross between an elite indica line Big Grain1 (BG1) and a japonica line Xiaolijing (XLJ) were used to map quantitative trait loci (QTLs) for source–sink size and heading date. Totally, thirty-one QTLs for...

Weiming Wu, Shihua Cheng

Field Crops Research > 2014 > 165 > Complete > 111-124

Rice is one of the most important cereal crops, feeding more than 50% population of the world. To meet the demand of increasing population, rice production has to be improved continually. As a very important part of rice plant, root system plays multiple roles in rice growth: anchorage of the plant, acquisition of water and nutrient elements, and biosynthesis of amino acids and hormones, etc. Almost...

Chao Wu, Yaping Fu, Guocheng Hu, Huamin Si, more

Planta > 2010 > 232 > 2 > 313-324

Appropriate leaf shape has proved to be useful in improving photosynthesis and increasing grain yield. To understand the molecular mechanism of leaf morphogenesis, we identified a rice mutant nrl1, which was characterized by a phenotype of narrow and rolled leaves. Microscopic observation showed that the mutation significantly decreased the number of vascular bundles of leaf and stem. Genetic analysis...

Structure, Evolution, and Expression of the Two Invertase Gene Families of Rice

Xuemei Ji, Wim Ende, Andre Laere, Shihua Cheng, more

Journal of Molecular Evolution > 2005 > 60 > 5 > 615-634

Invertases catalyze the irreversible hydrolysis of sucrose to glucose and fructose. Plants contain two unrelated families of these enzymes: acid forms that derive from periplasmic invertases of eubacteria and are found in cell wall and vacuole, and neutral/alkaline forms evolved from the cytosolic invertases of cyanobacteria. Genomes of rice (Oryza sativa) and thale cress (Arabidopsis thaliana) contain...
