Gibberellins-independent stem length regulation by YABBY1 in cucurbit crops

Blog Article

The enhanced translation of YABBY1 transcription factor could suppress stem elongation in a dose-dependent manner in cucurbit Crevice Nozzle crops, however, the genome editing mutant of YABBY1 was insensitive to exogenous gibberellins (GAs) treatment.To further explore the potential interaction of gibberellins signaling and CmoYABBY1, we investigated the gibberellins content and gene expression levels of gibberellins pathway between the bushy pumpkin Ball Bearing CmoM-4 and WT.The results suggested that CmoYABBY1 locates downstream of the GAs pathway, and the increased translation level of CmoYABBY1 in CmoM-4 may disturb the downstream signaling of gibberellins in a yet unknown regulatory mechanism.
