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.

The Effect of Grain Position on Genetic Improvement of Grain Number and Thousand Grain Weight in Winter Wheat in North China [PDF]

Frontiers in Plant Science, 2018
Genetic improvements have significantly contributed to wheat production. Five wheat cultivars—widely grown in north China in the 1950s, 1990s, or 2010s—were grown in field experiments conducted in the 2014–2015 and 2015–2016 growing seasons.

High night temperatures during grain number determination reduce wheat and barley grain yield: a field study

Global Change Biology, 2015
AbstractWarm nights are a widespread predicted feature of climate change. This study investigated the impact of high night temperatures during the critical period for grain yield determination in wheat and barley crops under field conditions, assessing the effects on development, growth and partitioning crop‐level processes driving grain number per ...

A novel Effective Panicle Number per Plant 4 haplotype enhances grain yield by coordinating panicle number and grain number in rice

Crop Journal
Increasing effective panicle number per plant (EPN) is one approach to increase yield potential in rice. However, molecular mechanisms underlying EPN remain unclear.

Identification of SMG3, a QTL Coordinately Controls Grain Size, Grain Number per Panicle, and Grain Weight in Rice. [PDF]

Front Plant Sci, 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. In this study, we identified a major QTL, SMG3, that is responsible for grain size, grain number per panicle, and grain weight in rice, which ...

A molecular framework for grain number determination in barley. [PDF]

Sci Adv, 2023
Flowering plants with indeterminate inflorescences often produce more floral structures than they require. We found that floral primordia initiations in barley ( Hordeum vulgare L.) are molecularly decoupled from their maturation into grains.

Natural variation in GNP3 determines grain number and grain yield in rice. [PDF]

Nat Commun
Grain number per panicle critically determines rice yield. Although many underlying genes have been reported, yet the molecular mechanisms linking ethylene to panicle development remain unclear. Here, we identify GRAIN NUMBER PER PANICLE 3 (GNP3) as a regulator of GNP through genome-wide association study (GWAS) combined with map-based cloning.

SMALL GRAIN 11 Controls Grain Size, Grain Number and Grain Yield in Rice [PDF]

Rice, 2016
Grain size is one of key agronomic traits that determine grain yield in rice. Several regulators of grain size have been identified in rice, but the mechanisms that determine grain size and yield remain largely unknown.Here we characterize a small grain (smg11) mutant in rice, which exhibits small grains, dense panicles and the increased number of ...

GW10, a Member of P450 Subfamily Regulates Grain Size and Grain Number in Rice [PDF]

Theoretical and Applied Genetics, 2021
Abstract Grain size and grain number play extremely important roles in rice grain yield. Here, we identify GW10 , which encodes a P450 subfamily protein and controlls grain size and grain number by using Lemont ( tropical japonica ) as donor parent and HJX74 ( indica ) as recipient parent. The GW10 locus was mapped into a 20.1 kb region

Effect of delayed sowing on grain number, grain weight, and protein concentration of wheat grains at specific positions within spikes

Journal of Integrative Agriculture, 2023
Delays in sowing have significant effects on the grain yield, yield components, and grain protein concentrations of winter wheat. However, little is known about how delayed sowing affects these characteristics at different positions in the wheat spikes ...
