Ferredoxin (Fd) protein as unique electron acceptor, involved in a variety of fundamental metabolic and signaling processes, which is indispensable for plant growth. The molecular mechanisms of Fd such as regulation of electron partitioning, impact of photosynthetic rate and involvement in the carbon fixing remain elusive in rice. Here we reported a heading(More)
Flag leaf is the most essential organ for photosynthesis in rice and its size plays an important role in rice breeding for ideal plant-type. Flag leaf size affect photosynthesis to a certain extent, thereby influencing rice production. Several genes controlling leaf size and shape have been identified with mutants. Although a number of quantitative trait(More)
A gene not only control tiller and plant height, but also regulate panicle structure by QTL dissection in rice. An ideal panicle structure is important for improvement of plant architecture and rice yield. In this study, using recombinant inbred lines (RILs) of PA64s and 93-11, we identified a quantitative trait locus (QTL), designated qPPB3 for primary(More)
DEAD-box proteins comprise a large protein family. These proteins function in all types of processes in RNA metabolism and are highly conserved among eukaryotes. However, the precise functions of DEAD-box proteins in rice physiology and development remain unclear. In this study, we identified a rice DEAD-box protein, OsRH17, that contains a DEAD domain and(More)
In cereal crops, vegetative and spikelet development play important roles in grain yield and quality, but the genetic mechanisms that control vegetative and spikelet development remain poorly understood in rice. Here, we identified a new rice mutant, defective glume 1 (dg1) mutant from cultivar Zhonghua11 after ethyl methanesulfonate treatment. The dg1(More)
Seedling vigor is an important agricultural trait as direct-seeded rice technology becomes widely applied. In order to investigate the genetic mechanisms underlying seedling vigor in rice, seeds of 132 recombinant inbred lines (RILs) derived from 93-11 and PA64s, harvested from Lingshui and Hangzhou were cultivated in the nutrient solution, and four indices(More)
An ideal appearance is of commercial value for rice varieties. Chalkiness is one of the most important appearance quality indicators. Therefore, clarification of the heredity of chalkiness and its molecular mechanisms will contribute to reduction of rice chalkiness. Although a number of QTLs related to chalkiness were mapped, few of them have been cloned so(More)
Leaf color-related mutants are important materials to study the chlorophyll biosynthesis and chloroplast development. Here, we isolated and characterized a thermosensitive yellow-green leaf mutant, ygl, through mutagenized Japonica rice cultivar Zhonghua11 by EMS. The mutant showed yellow-green leaves only at the seedling stage. Genetic and molecular(More)
