The Identification and Characterization of WOX Family Genes in Coffea arabica Reveals Their Potential Roles in Somatic Embryogenesis and the Cold-Stress Response.

ABSTRACT: WUSCHEL-related homeobox (WOX) genes play significant roles in plant development and stress responses. Difficulties in somatic embryogenesis are a significant constraint on the uniform seedling production and genetic modification of Coffea arabica, hindering efforts to improve coffee production in Yunnan, China. This study comprehensively analyzed WOX genes in three Coffea species. A total of 23 CaWOXs, 12 CcWOXs, and 10 CeWOXs were identified. Transcriptomic profile analysis indicated that about half of the CaWOX genes were actively expressed during somatic embryogenesis. The most represented CaWOXs were CaWOX2a, CaWOX2b, CaWOX8a, and CaWOX8b, which are suggested to promote the induction and
