Genome-wide analysis of the Alba gene family members in soybean (Glycine max L.): characterization and stress-responsive expression patterns.

ABSTRACT:

Background

The Alba (Acetylation lowers binding affinity) protein family consists of small, conserved nucleic acid-binding proteins involved in regulating gene expression and stress responses. Although studied in several plants, their roles in legumes remain poorly understood. Characterizing Alba genes in soybean (Glycine max L.), a crop highly affected by climate stress, is essential for improving its stress resilience.

Results

In this study, a total of 15 Glycine max Alba (GmAlba) genes were identified, unevenly distributed across 14 chromosomes with varied exon-intron structures and conserved hydrophilic domains. Phylogenetic analysis grouped them into five clades: Groups 1-2 (Rpp25-like) and Groups 3-5 (Rpp20-like), with Group 4 only containing soybean-specific members,
