Expression Profiling and MicroRNA Regulatory Networks of Homeobox Family Genes in Sugarcane Saccharum spontaneum L.

ABSTRACT: Homeobox (HB) genes play important roles in plant growth and development processes, particularly in the formation of lateral organs. Thus, they could influence leaf morphogenesis and biomass formation in plants. However, little is known about HBs in sugarcane, a crucial sugar crop, due to its complex genetic background. Here, 302 allelic sequences for 104 HBs were identified and divided into 13 subfamilies in sugarcane Saccharum spontaneum. Comparative genomics revealed that whole-genome duplication (WGD)/segmental duplication significantly promoted the expansion of the HB family in S. spontaneum, with SsHB26, SsHB63, SsHB64, SsHB65, SsHB67, SsHB95, and SsHB96 being retained from the evolutionary event befo
