A new SNP in cyOsPPDK gene is associated with floury endosperm in Suweon 542
Pyruvate orthophosphate dikinase (PPDK) is a component of glycolysis to mediate endosperm energy charge by adjusting the ratio of ATP to ADP and AMP that proposed to balance the flow of carbon into starch, pro...

Quantitative shotgun proteomic analysis of cold-stressed mature rice anthers
Rice crops are vulnerable to low temperatures. During development, the reproductive stage is particularly sensitive to cold exposure, which causes abnormal pollen development and a high degree of male sterilit...

Article
Analysis of quantitative trait loci associated with seed germination and coleoptile length under low temperature condition
Low temperature stress will lower the germination rate of rice, reduce its growth, and delay the emergence of rice seedlings from paddy water surface, resulting in decreased seedling and mortality. Here, we co...

Open AccessA quantitative shotgun proteomics analysis of germinated rice embryos and coleoptiles under low-temperature conditions
At low temperatures, rice grains have a reduced germination rate and grow more slowly, which delays the emergence of rice seedlings from the paddy water surface and significantly increases seedling mortality. ...

Article
QTLs for hybrid fertility and their association with female and male sterility in rice
Hybrid sterility is one of the major barriers to the application of wide crosses in plant breeding and is commonly encountered in crosses between indica and japonica rice varieties. Ten map** populations compri...

Xyloglucan endotransglycosylase/hydrolase genes in cotton and their role in fiber elongation
Plant cell wall extensibility is mediated, in part, by xyloglucan endotransglycosylases/hydrolases (XTH) that are able to cleave and reattach xyloglucan polymers that make up the hemicelluloses matrix of type ...
