Expression Pattern of FT/TFL1 and miR156-Targeted SPL Genes Associated with Developmental Stages in Dendrobium catenatum.

ABSTRACT: Time to flower, a process either referring to juvenile-adult phase change or vegetative-reproductive transition, is strictly controlled by an intricate regulatory network involving at least both FT/TFL1 and the micro RNA (miR)156-regulated SPL family members. Despite substantial progresses recently achieved in Arabidopsis and other plant species, information regarding the involvement of these genes during orchid development and flowering competence is still limited. Dendrobium catenatum, a popular orchid species, exhibits a juvenile phase of at least three years. Here, through whole-genome mining and whole-family expression profiling, we analyzed the homologous genes of FT/TFL1, miR156, and SPL with special reference to the developmental stages. The FT/TFL1 family contains nine members; am
