Genome-Wide Identification and Expression Analysis of JAZ Family Involved in Hormone and Abiotic Stress in Sweet Potato and Its Two Diploid Relatives
Jasmonate ZIM-domain (JAZ) proteins are key repressors of a jasmonic acid signaling pathway. They play essential roles in the regulation of plant growth and development, as well as environmental stress responses. However, this gene family has not been explored in sweet potato.

| description | Jasmonate ZIM-domain (JAZ) proteins are key repressors of a jasmonic acid signaling pathway. They play essential roles in the regulation of plant growth and development, as well as environmental stress responses. However, this gene family has not been explored in sweet potato. In this study, we identified 14, 15, and 14 <i>JAZ</i><i>s</i> in cultivated hexaploid sweet potato (<i>Ipomoea batatas</i>, 2n = 6x = 90), and its two diploid relatives <i>Ipomoea trifida</i> (2n = 2x = 30) and <i>Ipomoea triloba</i> (2n = 2x = 30), respectively. These <i>JAZs</i> were divided into five subgroups according to their phylogenetic relationships with <i>Arabidopsis</i>. The protein physiological properties, chromosome localization, phylogenetic relationship, gene structure, promoter <i>cis</i>-elements, protein interaction network, and expression pattern of these 43 <i>JAZs</i> were systematically investigated. The results suggested that there was a differentiation between homologous <i>JAZs</i>, and each <i>JAZ</i> gene played different vital roles in growth and development, hormone crosstalk, and abiotic stress response between sweet potato and its two diploid relatives. Our work provided comprehensive comparison and understanding of the <i>JAZ</i> genes in sweet potato and its two diploid relatives, supplied a theoretical foundation for their functional study, and further facilitated the molecular breeding of sweet potato. |
