Fine Mapping of a Novel defective glume 1 (dg1) Mutant, Which Affects Vegetative and Spikelet Development in Rice
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 mutant displayed the dwarfism with small, ...
متن کاملMULTI-FLORET SPIKELET1, which encodes an AP2/ERF protein, determines spikelet meristem fate and sterile lemma identity in rice.
The spikelet is a unique inflorescence structure of grass. The molecular mechanism that controls the development of the spikelet remains unclear. In this study, we identified a rice (Oryza sativa) spikelet mutant, multi-floret spikelet1 (mfs1), that showed delayed transformation of spikelet meristems to floral meristems, which resulted in an extra hull-like organ and an elongated rachilla. In a...

متن کاملRice plant development: from zygote to spikelet.
Rice is becoming a model plant in monocotyledons and a model cereal crop. For better understanding of the rice plant, it is essential to elucidate the developmental programs of the life cycle. To date, several attempts have been made in rice to categorize the developmental processes of some organs into substages. These studies are based exclusively on the morphological and anatomical viewpoints...
متن کامل‘Two‐floret spikelet’ as a novel resource has the potential to increase rice yield
Yield in rice (Oryza sativa) is determined by three major components: panicle number per plant, grain weight and grain/ spikelet number per panicle (Zhou et al., 2015). Grain number per panicle is one of the main targets and mainly results from the number of spikelets. Traditionally, rice breeders have focused on the improvement of spikelet number per panicle and rarely focused on the number of...
