GhAAO2 was observed responding to NaHCO₃ stress in cotton compared to AAO family genes.

ABSTRACT:

Background

Abscisic acid (ABA) is an important stress hormone, the changes of abscisic acid content can alter plant tolerance to stress, abscisic acid is crucial for studying plant responses to abiotic stress. The abscisic acid aldehyde oxidase (AAO) plays a vital role in the final step in the synthesis of abscisic acid, therefore, understanding the function of AAO gene family is of great significance for plants to response to abiotic stresses.

Result

In this study, 6, 8, 4 and 4 AAO genes were identified in four cotton species. According to the structural characteristics of genes and the traits of phylogenetic tree, we divided the AAO gene family into 4 clades. Gene structure analysis showed that the AAO gene family was relatively conservative. The analysis of cis-elements
