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.

OsSPL9 Regulates Grain Number and Grain Yield in Rice [PDF]

Frontiers in Plant Science, 2021
Rice grain yield consists of several key components, including tiller number, grain number per panicle (GNP), and grain weight. Among them, GNP is mainly determined by panicle branches and spikelet formation. In this study, we identified a gene affecting

The da1 mutation in wheat increases grain size under ambient and elevated CO2 but not grain yield due to trade‐off between grain size and grain number [PDF]

Plant-Environment Interactions, 2021
Why this research Matters Grain size is potentially yield determining in wheat, controlled by the ubiquitin pathway and negatively regulated by ubiquitin receptor DA1.

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.

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.

The role of endogenous hormones in regulating grain number in oat panicles under drought stress across cultivars [PDF]

Frontiers in Plant Science
IntroductionDrought stress poses a major constraint on oat (Avena sativa L.) yield formation. Endogenous phytohormones play a crucial role in the adaptive mechanisms of oat.

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.

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 ...

Combined Analysis of BSA-Seq Based Mapping, RNA-Seq, and Metabolomic Unraveled Candidate Genes Associated with Panicle Grain Number in Rice (Oryza sativa L.) [PDF]

Biomolecules, 2022
Rice grain yield is a complex and highly variable quantitative trait consisting of several key components, including the grain weight, the effective panicles per unit area, and the grain number per panicle (GNPP). The GNPP is a significant contributor to

Phytohormone-Mediated Molecular Mechanisms Involving Multiple Genes and QTL Govern Grain Number in Rice [PDF]

Frontiers in Genetics, 2020
Increasing the grain number is the most direct route toward enhancing the grain yield in cereals. In rice, grain number can be amplified through increasing the shoot branching (tillering), panicle branching, panicle length, and seed set percentage ...
