OsMADS17 simultaneously increases grain number and grain weight in rice
Nature Communications, 2023 AbstractDuring the processes of rice domestication and improvement, a trade-off effect between grain number and grain weight was a major obstacle for increasing yield. Here, we identify a critical gene COG1, encoding the transcription factor OsMADS17, with a 65-bp deletion in the 5′ untranslated region (5′ UTR) presented in cultivated rice increasing ...

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 research for plant molecular biology. The developmental trait of grain weight is affected by multiple

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 ...

Superior grains determined by grain weight are not fully correlated with the flowering order in rice
Journal of Integrative Agriculture, 2015 Rice panicles are composed of many branches with two types of extreme grains, the superior and the inferior. Traditionally, it has been well accepted that earlier flowers result in superior grains and late flowers generate inferior grains. However, these correlations have never been strictly examined in practice.

Control of Thousand-Grain Weight by OsMADS56 in Rice [PDF]
International Journal of Molecular Sciences, 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.

Wheat grain width: A clue for re-exploring visual indicators of grain weight [PDF]
Plant Methods, 2021 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 ...

Responses of nitrogen accumulation and translocation in five cytoplasmic hybrid rice cultivars
Plant, Soil and Environment, 2022 To study the difference among cytoplasm at the different nitrogen conditions, a research experiment was conducted using five different cytoplasmic male sterile (CMS) hybrid rice with nitrogen levels at N0, N1, N2, and N3; the nitrogen application rates ...

The effect of foliar application of nutrients and humic acid on grain yield and quality of bread wheat cultivars under drought stress [PDF]
تنش های محیطی در علوم زراعی, 2023 IntroductionAbsorption of nutrients from the soil depends on soil moisture, fertilizer application, soil nutrients and other factors. Foliar application of nutrients under water stress is one of the ways to reduce the effect of stress on the quantity and
