OsMADS17 simultaneously increases grain number and grain weight in rice [PDF]

Nature Communications, 2023
During the processes of rice domestication and improvement, a trade-off effect between grain number and grain weight was a major obstacle for increasing yield.

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 ...

Genetic and Molecular Factors Determining Grain Weight in Rice [PDF]

Frontiers in Plant Science, 2021
Grain weight is one of the major factors determining single plant yield production of rice and other cereal crops. Research has begun to reveal the regulatory mechanisms underlying grain weight as well as grain size, highlighting the importance of this ...

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.

Grain Weight and Taste Quality in Japonica Rice Are Regulated by Starch Synthesis and Grain Filling Under Nitrogen–Phosphorus Interactions [PDF]

Plants
To reveal the regulatory effects of nitrogen and phosphorus interactions on grain-filling- and starch-synthesis-related enzymes, and grain weight of superior grains (SGs) and inferior grains (IGs) and taste quality, the japonica rice cultivar Shennong ...

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

Plant Commun
Grain 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 ...

Wheat grain width: a clue for re-exploring visual indicators of grain weight. [PDF]

Plant Methods, 2022
AbstractMean 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, MGW estimations has been limited to ...

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.

Integrated Multi-Omics Reveals the Molecular Basis Underlying Wheat Grain Development and Identifies TaYAK1-2D as a Positive Grain Weight Regulator [PDF]

Plants
Grain weight, a highly heritable yield component, is a primary breeding target for enhancing wheat productivity. Unraveling the molecular dynamics underlying grain development is essential for identifying key regulators controlling this trait.

The OsMAPK5-OsWRKY72 module negatively regulates grain length and grain weight in rice. [PDF]

J Integr Plant Biol
ABSTRACTGrain 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 ...
