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

Summary: | 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 cells. In situ expression analysis revealed the coexistence of the
CmTCP1
and
CmYAB1
mRNAs in the abaxial domains of developing tendrils. An RNA-seq analysis of the seven
YABBY
genes in the melon genome revealed relatively high expression ratios of
CmYAB1
in tendrils compared with those in leaves. These results suggest a novel function of the YABBY protein through its interaction with a TCP protein in the development of cucurbit tendrils. |
