Characterization and expression analysis of the B3 gene family during seed development in Akebia trifoliata.

ABSTRACT:

Background

B3 genes encode transcription factors that play key roles in plant growth and development. However, the specific B3 genes involved in the seed development of Akebia trifoliata remain unexplored.

Results

A total of 72 AktB3 genes were identified and classified into five subfamilies (ARF, LAV, RAV, HSI, and REM) based on phylogenetic analysis. These 72 AktB3 genes were unevenly distributed across 16 chromosomes. Collinear analysis indicated that segmental duplication has played a significant role in the evolution of AktB3 genes, and underwent purification selection. Expression profiling across seed development stages revealed that seven AktB3 genes, particularly from the LAV subfamily (AktABI3, AktFUS3, AktLEC2), were up-regulated at 70 days after flowering (DAF).
