Genetic and Environmental Variations and Associations of the Characters Related to the Grain-Filling Process in Rice Cultivars

Plant Production Science, 1999
We examined the involvement of genetic and environmental factors in the variations and associations of the rate and duration of grain filling and the final grain weight in rice cultivars, instead of the simple phenotypic correlation and variance.

Dynamic Analysis of Gene Expression in Rice Superior and Inferior Grains by RNA-Seq. [PDF]

PLoS ONE, 2015
Poor grain filling of inferior grains located on lower secondary panicle branch causes great drop in rice yield and quality. Dynamic gene expression patterns between superior and inferior grains were examined from the view of the whole transcriptome by ...

Grain-filling characteristics and yield differences of maize cultivars with contrasting nitrogen efficiencies

Crop Journal, 2020
To investigate the effect of nitrogen management on the grain-filling characteristics and yield formation of maize cultivars with contrasting nitrogen efficiencies, and to identify differences in grain-filling characteristics and yield of maize cultivars

RGB1 Regulates Grain Development and Starch Accumulation Through Its Effect on OsYUC11-Mediated Auxin Biosynthesis in Rice Endosperm Cells

Frontiers in Plant Science, 2021
RGB1, a subunit of heterotrimeric G protein, plays important roles in regulating grain size and weight of rice. However, the molecular mechanisms underlying controlling grain filling process by G protein are still largely unclear.

Comparative Effects of Heat Stress at Booting and Grain-Filling Stage on Yield and Grain Quality of High-Quality Hybrid Rice

, 2023
Rice plants are highly sensitive to high-temperature stress, posing challenges to grain yield and quality. However, the impact of high temperatures on the quality of high-quality hybrid rice during the booting stage, as well as the differing effects of ...

Proteome Analysis of Grain Filling and Seed Maturation in Barley [PDF]

Plant Physiology, 2002
Abstract In monocotyledonous plants, the process of seed development involves the deposition of reserves in the starchy endosperm and development of the embryo and aleurone layer. The final stages of seed development are accompanied by an increase in desiccation tolerance and drying out of the mature seed.

Integrated agronomic practices management improved grain formation and regulated endogenous hormone balance in summer maize (Zea mays L.)

Journal of Integrative Agriculture, 2020
Compared with single agronomic practices management during grain formation, knowledge about integrated agronomic practices management on grain-filling characteristics and physiological function of endogenous hormones was limited. In order to clarify this

Characterization and expression patterns of microRNAs involved in rice grain filling. [PDF]

PLoS ONE, 2013
MicroRNAs (miRNAs) are upstream gene regulators of plant development and hormone homeostasis through their directed cleavage or translational repression of the target mRNAs, which may play crucial roles in rice grain filling and determining the final ...

Effects of powdery mildew on grain filling in spring barley in contrasting environments

, 1984
Circumstantial evidence from field experiments at Rothamsted suggested that effects of powdery mildew on grain filling in spring barley may be determined partly by temperature during the grain‐filling period.
