Characterization and expression analysis of SnRK2, PYL, and ABF/ AREB/ ABI5 gene families in sweet potato.

ABSTRACT: Abscisic acid (ABA) signaling in plants is essential to several aspects of plant development, such as tolerance to environmental stresses and growth. ABA signaling is also important for storage organ formation in crops, such as sweet potato. However, the repertoire of I. batatas ABA signaling gene families has not yet been fully characterized, so that it is unclear which members of these families are necessary for tuberization. Therefore, genome-wide identification of the sweet potato ABF/ AREB/ ABI5, SnRK2, and PYL gene families was performed, along with phylogenetic, motif, cis-regulatory element (CRE), and expression analyses. Nine ABF, eight SnRK2, and eleven PYL gene family members were identified, and there was high sequence conservation among these proteins that were revealed by phy
