Genome-wide identification of the YABBY gene family and functional characterization of TaYABBY4A in wheat (Triticum aestivum L.).

ABSTRACT:

Background

YABBYs are plant-specific transcription factors that play crucial roles in plant growth, development, and stress responses. Despite extensive studies in various plant species, a systematic analysis of YABBYs in wheat grains is still lacking.

Results

In this study, 21 TaYABBYs were identified using the Chinese Spring wheat genome database and were divided into four subfamilies through phylogenetic analysis. Gene collinearity analysis revealed the evolutionary characteristics of the TaYABBYs. Analysis of cis-acting elements in the promoter region identified elements related to endosperm development. SNP analysis uncovered genetic variations within the YABBY gene family. Meanwhile, RNA-Seq and qRT-PCR techniques were employed to explore the expression patterns of TaY
