OsNLP3 enhances grain weight and reduces grain chalkiness in rice [PDF]
Plant CommunicationsGrain 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 ...

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 chromosome 10.

Carpel size, grain filling, and morphology determine individual grain weight in wheat [PDF]
Journal of Experimental Botany, 2015 Individual grain weight is a major yield component in wheat. To provide a comprehensive understanding of grain weight determination, the carpel size at anthesis, grain dry matter accumulation, grain water uptake and loss, grain morphological expansion, and final grain weight at different positions within spikelets were investigated in a recombinant ...

The OsMAPK5–OsWRKY72 module negatively regulates grain length and grain weight in rice [PDF]
Journal of Integrative Plant BiologyABSTRACTGrain 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 ...

Wheat grain width: a clue for re-exploring visual indicators of grain weight. [PDF]
Plant Methods, 2022 Abstract Mean grain weight (MGW) is among the most frequently measured parameters in wheat breeding and physiology. Although in the recent decades, various wheat grain analyses (e.g. counting, and determining the size, color, or shape features) have been facilitated thanks to the automated image processing systems ...

OsSPL18 controls grain weight and grain number in rice
Journal of Genetics and Genomics, 2019 Grain weight and grain number are two important traits directly determining grain yield in rice. To date, a lot of genes related to grain weight and grain number have been identified; however, the regulatory mechanism underlying these genes remains largely unknown.
