Expansion and stress responses of the AP2/EREBP superfamily in cotton.

ABSTRACT:

Background

The allotetraploid cotton originated from one hybridization event between an extant progenitor of Gosssypium herbaceum (A₁) or G. arboreum (A₂) and another progenitor, G. raimondii Ulbrich (D₅) 1-1.5 million years ago (Mya). The APETALA2/ethylene-responsive element binding protein (AP2/EREBP) transcription factors constitute one of the largest and most conserved gene families in plants. They are characterized by their AP2 domain, which comprises 60-70 amino acids, and are classified into four main subfamilies: the APETALA2 (AP2), Related to ABI3/VP1 (RAV), Dehydration-Responsive Element Binding protein (DREB) and Ethylene-Responsive Factor (ERF) subfamilies. The AP2/EREBP genes play crucial roles in plant growth, development and biotic an
