Interaction between plant-specific transcription factors TCP and YABBY expressed in the tendrils of the melon Cucumis melo.

ABSTRACT: Plant tendrils are specialized organs that can twine around other structures to facilitate climbing. They occur in a variety of plant families and have diverse ontogenic origins. In cucurbits, tendrils originate from lateral shoots. Fine mapping verified that the tendril-less ctl mutation of the melon Cucumis melo corresponds to a frameshift mutation in the CmTCP1 gene, which encodes a TCP transcription factor. A yeast two-hybrid screen for CmTCP1/CTL-interacting proteins identified a member of the plant-specific YABBY transcription factor family, which was named CmYAB1. Each of the N- and C-terminal regions of CmTCP1 interacted with CmYAB1. The ctl mutation impaired the interaction between CmTCP1 and CmYAB1. Both proteins interacted in vitro and were localized to the nucleus in plant cell
