Genome-wide identification of the TIFY gene family in Helianthus annuus and expression analysis in response to drought and salt stresses.

ABSTRACT: Given the increasing recognition of frequent drought problems associated with global warming, sunflower (Helianthus annuus L.) has been widely studied as a model plant tolerant to drought and salt stresses. However, there is a lack of information on the systematic identification of the sunflower HaTIFY gene family. In the present study, 21 HaTIFY genes in sunflower were identified and the members of HaTIFY family were divided into four subfamilies, i.e., TIFY, JAZ, ZML and PPD. Gene duplication is a major driver for the expansion of the gene family. Here, three segmental and two tandem duplicated gene pairs were identified via duplication and synteny analysis. Furthermore, five paralogous TIFY gene pairs might have undergone purifying selective pressure during evolution based on Ka/Ks rati
