Genome-wide identification of JAZ genes has been performed in many plant species. However, systematic information about pineapple (<i>Ananas comosus</i> L. Merr.) <i>JAZ</i> genes (<i>AcJAZs</i>) is still not available. In this study, we identified 14 <i>AcJAZ</i> genes and classified them into five groups along with the Arabidopsis and rice orthologs. The <i>AcJAZ</i> genes have 3-10 exons, and the putative AcJAZ proteins have between two and eight conserved regions, including the TIFY motif and Jas domain. The <i>cis</i>-acting element analysis revealed that the putative promoter regions of <i>AcJAZs</i> contain betBiologyInvestigation of the JASMONATE ZIM-DOMAIN Gene Family Reveals the Canonical JA-Signaling Pathway in Pineapple.PMC894560131970333, 321703802019N51010021, KJB19006ACao LAslam MGuo XQin YZheng PDeng FHu BCheng YZhao XYe LHe XJiao SWang YYe KDong CZhao HfalseInvestigation of the JASMONATE ZIM-DOMAIN Gene Family Reveals the Canonical JA-Signaling Pathway in Pineapple.JASMONATE ZIM-DOMAIN (JAZ) proteins are negative regulators of the jasmonate (JA)-signaling pathway and play pivotal roles in plant resistance to biotic and abiotic stresses.
