The Candidate Genes Underlying a Stably Expressed QTL for Low Temperature Germinability in Rice (Oryza sativa L.)
Rice Low temperature germinability Quantitative trait locus Candidate gene Genomewide association study
2023/4/21
Background: Direct seeding is an efficient cultivation technique in rice. However, poor low temperature germinability (LTG) of modern rice cultivars limits its application. Identifying the genes assoc...

OsYUC11-mediated auxin biosynthesis essential for grain filling of rice
OsYUC11 auxin grain filling rice
2023/7/20
Auxin is a phytohormone essential for plant development. However, our understanding of auxin-regulated endosperm development remains limited. Here, we described rice YUCCA (YUC) flavin-containing mono...
DEEP GREEN PANICLE1 suppresses GOLDEN2-LIKE activity to reduce chlorophyll synthesis in rice glumes
DGP1 OsGLK Chlorophyll Photosynthesis Rice Oryza sativa L.
2023/7/20
Understanding the regulation mechanisms of photosynthesis is key to improving its efficiency and, ultimately, crop yield. In this study, we report that DEEP GREEN PANICLE1 (DGP1) is involved in photos...
Lysine biofortification in rice by modulating feedback inhibition of aspartate kinase and dihydrodipicolinate synthase
rice Lysine aspartate kinase dihydrodipicolinate synthase
2023/7/20
Lysine is the main limiting essential amino acid (EAA) in the rice seeds, which is a major energy and nutrition source for humans and livestock. In higher plants, the rate-limiting steps in lysine bio...
Incorporation of parental phenotypic data into multi-omic models improves prediction of yield-related traits in hybrid rice
parental phenotypic data multi-omic models yield-related traits hybrid rice

Hybrid breeding has been shown to effectively increase rice productivity. However, identifying desirable hybrids out of numerous potential combinations is a daunting challenge. Genomic selection holds...
Development of marker-free rice with stable and high resistance to rice black-streaked dwarf virus disease through RNA interference
marker-free rice black-streaked dwarf virus disease RNA
2023/8/9
The rice black-streaked dwarf virus (RBSDV) disease causes severe rice yield losses in Asia. RNA interference (RNAi) has been widely applied to develop antiviral varieties in plants. So far, only a fe...
Functional divergence of two duplicated Fertilization Independent Endosperm genes in rice with respect to seed development
Fertilization Endosperm genes rice
2023/8/9
Fertilization Independent Endosperm(FIE) is an essential member of Polycomb Repressive Complex 2(PRC2) that plays important roles in the developmental regulation of plants. OsFIE1 and OsFIE2 are two F...
The maternally expressed polycomb group gene OsEMF2a is essential for the endosperm cellularization and imprinting in rice
maternally expressed polycomb group gene OsEMF2 aendosperm cellularization
2023/8/9
Cellularization is a key event in endosperm development. Polycomb group (PcG) genes, such as Fertilization-Independent Seed 2 (FIS2), are vital for the syncytium-to-cellularization transitio...
