Preharvest sprouting (PHS) is an unfavorable trait in cereal crops and causes serious yield loss. However, the molecular mechanism underlying PHS remains largely elusive. Here, we identified a member of 9-cis-epoxycarotenoid dioxygenase family, OsNCED3, which regulates grain development rice (Oryza sativa L.). OsNCED3 encodes chloroplast-localized abscisic acid (ABA) biosynthetic enzyme highly expressed embryo developing seeds. Disruption by CRISPR/Cas9-mediated mutagenesis led to lower ABA...
Summary Chilling stress has seriously limited the global production and geographical distribution of rice. However, molecular mechanisms associated with plant responses to chilling are less known. In this study, we revealed a member β‐ketoacyl‐ACP synthase I family (KASI), OsKASI‐2 which confers tolerance in encodes chloroplast‐localized KASI enzyme mainly expressed leaves anthers rice strongly induced by stress. Disruption led decreased KAS enzymatic activity levels unsaturated fatty acids,...
Abstract Chilling stress has become a major limiting factor that reduces crop productivity worldwide. In this study, we identified new gene bHLH57 , whose product enhances chilling tolerance in rice at diverse developmental stages. was mainly expressed leaves and anthers, its protein targeted to the nucleus. Overexpression of enhanced by increasing trehalose synthesis, whereas mutants CRISPR/Cas9‐mediated mutagenesis were more sensitive had reduced trehalose. Meanwhile, may regulate ROS...
Genetic transformation is an important strategy for revealing gene function, and it used extensively in both functional genomics study molecular breeding of rice. Demand its application wild Oryza species rising their extensive genetic diversity. However, accessions with AA genome using calli induced from scutellum tissue embryos mature seeds has not been successfully established. In the present study, we Chaling common rice (CLCWR) (Oryza rufipogon Griff.) to establish...
Zhu1S is a thermosensitive genic male-sterile (TGMS) line of rice possessing outstanding combining ability and low critical temperature, which has been extensively utilized as female parent in two-line hybrid ricebreeding. However, the fertility Zhu 1S during seed production frequently affected by high thus leading to its alteration aborted production. To understand conversion mechanism under we employed transcriptomics analyses on anthers young panicles alternation sensitivity stage (Zhu...
Rice (Oryza sativa L.) is susceptible to various abiotic stresses, such as salt, cold, and drought. Therefore, there an urgent need explore the relevant genes that enhance tolerance these stresses. In this study, we identified a gene, OsNCED4 (9-cis-epoxycarotenoid dioxygenase 4), which regulates multiple encodes chloroplast-localized abscisic acid (ABA) biosynthetic enzyme. The expression of gene was significantly induced by 150 mM NaCl cold stress. Disruption CRISPR (Clustered Regularly...
Abstract Functional genomics research on indica rice is often hindered by its long growth cycle and recalcitrance to genetic transformation. Therefore, there an urgent need for Arabidopsis ‐like varieties that have a high efficiency in transformation order facilitate functional research. Here, we report the development of new variety, named 6‐23, which has significantly short can be used as model system. 6‐23 recombinant inbred line created crossing Chaling common wild with Guanglu'ai‐4. The...
