Unraveling the unique role of DELLA proteins in grapevine flowering
The transition from vegetative to reproductive stages in plants involves both internal and external cues, with grapevines (Vitis vinifera L. cv. Pixie) presenting a unique case. Research shows that a mutation in the grapevine's DELLA proteins enhances the conversion of tendrils to inflorescences, diverging from DELLA's typical role in suppressing flowering in annual plants.
