Identification of SMG3, a QTL Coordinately Controls Grain Size, Grain Number per Panicle, and Grain Weight in Rice [PDF]
Frontiers in Plant Science, 2022 Grain size, grain number per panicle, and grain weight are key agronomic traits that determine grain yield in rice. However, the molecular mechanisms coordinately controlling these traits remain largely unknown.

Control of Thousand-Grain Weight by OsMADS56 in Rice. [PDF]
Int J Mol Sci, 2021 Grain weight and size are important traits determining grain yield and influencing grain quality in rice. In a previous study, a quantitative trait locus controlling thousand-grain weight (TGW) in rice, qTGW10-20.8, was mapped in a 70.7 kb region on ...

Natural allelic variation in GRAIN SIZE AND WEIGHT 3 of wild rice regulates the grain size and weight [PDF]
Plant Physiology, 2023 Grain size is important for yield in rice (Oryza sativa L.). Although many genes involved in grain size have been isolated, few can be used in breeding due to their interactions and phenotypic effects.

OsNLP3 enhances grain weight and reduces grain chalkiness in rice. [PDF]
Plant CommunGrain weight, a key determinant of yield in rice (Oryza sativa L.), is governed primarily by genetic factors, whereas grain chalkiness, a detriment to grain quality, is intertwined with environmental factors such as mineral nutrients. Nitrogen (N) is recognized for its effect on grain chalkiness, but the underlying molecular mechanisms remain to be ...

Genes Impacting Grain Weight and Number in Wheat (Triticum aestivum L. ssp. aestivum). [PDF]
Plants (Basel), 2022 The primary goal of common wheat (T. aestivum) breeding is increasing yield without negatively impacting the agronomic traits or product quality. Genetic approaches to improve the yield increasingly target genes that impact the grain weight and number ...

The OsMAPK5-OsWRKY72 module negatively regulates grain length and grain weight in rice. [PDF]
J Integr Plant BiolABSTRACTGrain size and grain weight are important determinants for grain yield. In this study, we identify a novel OsMAPK5–OsWRKY72 module that negatively regulates grain length and grain weight in rice. We found that loss‐of‐function of OsMAPK5 leads to larger cell size of the rice spikelet hulls and a significant increase in both grain length and ...

Understanding complex genetic architecture of rice grain weight through QTL-meta analysis and candidate gene identification. [PDF]
Sci Rep, 2022 Quantitative trait loci (QTL) for rice grain weight identified using bi-parental populations in various environments were found inconsistent and have a modest role in marker assisted breeding and map-based cloning programs.
