A comprehensive in silico genome-wide identification and characterization of SQUAMOSA promoter binding protein (SBP) gene family in Musa acuminata.

ABSTRACT: One of the largest and most significant transcription factor gene families in plants is the SQUAMOSA promoter binding protein (SBP) gene family and they perform critical regulatory roles in floral enhancement, fruit development, and stress resistance. The SBP protein family (also known as SPL) has not yet been thoroughly studied in the staple fruit crop, banana. A perennial monocot plant, banana is essential for ensuring food and nutrition security. This work detected 41 SBP genes in the banana species Musa acuminata. The MaSBPs were subsequently elucidated by investigating their gene structure, chromosomal position, RNA-Seq data, along with evolutionary connections with Arabidopsis and rice. Sequence alignment of MaSBPs revealed that all genes included a domain of two Zn finger motifs (CC
