Background Polyploidy has pivotal influences on rice (Oryza sativa L.) morphology and
physiology, and is very important for understanding rice domestication and improving …

Heterosis is a common phenomenon in which the hybrids exhibit superior agronomic
performance than either inbred parental lines. Although hybrid rice is one of the most …

Photosynthesis is an essential biological process and a key approach for raising crop yield.
However, photosynthesis in rice is not fully investigated. This study reported the …

Chlorophyll metabolic pathways and chloroplast development have been studied
systematically by both biochemical and genetic approaches. However, the effect of them on …

The two-line system has been widely used in hybrid rice seed production, and the reverse
photoperiod-sensitive genic male sterile line is a new germplasm with an opposite …

Polyploid rice hybrids have a powerful biological and yield potential that may become a new
way for rice breeding; however, low fertility is major hindrance in commercial utilization …

Elite rice hybrids, when compared to their parental lines, exhibit increased yield and other
favorable agronomical traits, such as pathogen‐and water‐stress resistances, which are …

Autotetraploid rice is developed from diploid rice by doubling the chromosomes, leading to
higher nutritional quality. Nevertheless, there is little information about the abundances of …

The two-line hybrid rice is an important factor of a global crop, but its fertility transition
mechanism is unclear. Here, a comparative proteomics and transcriptomics analysis was …

Background Neo-tetraploid rice (NTR) is a new tetraploid rice germplasm that developed
from the crossing and directional selection of different autotetraploid rice lines, which …
