Overexpression of PvSTK1 gene from Switchgrass (Panicum virgatum L.) affects flowering time and development of floral organ in transgenic Arabidopsis thaliana.

Flowering means that the plant enters the reproductive growth stage, which is a crucial stage in the plant life cycle. Delaying flowering time to prolong vegetative growth is an important method to increase biomass yield and saccharification efficiency in switchgrass, It is of great significance to study the molecular mechanism of plant flowering and regulate the process of plant flowering in the process of biomass production. In this study, we identified 55 serine/threonine-protein kinase genes related to flower development from the switchgrass transcriptome database.

Regulatory Network of Preharvest Sprouting Resistance Revealed by Integrative Analysis of mRNA, Noncoding RNA, and DNA Methylation in Wheat.

Preharvest sprouting (PHS) of grain occurs universally and sharply decreases grain quality and yield, but the mechanism remains unclear. MingXian169, a breeding inducer wheat for stripe rust, is widely used in the Huanghuai wheat-producing region, China. In this study, we found that MingXian169 could be considered an ideal material for PHS research because of its high PHS resistance.
