Plant hormone has dual role in triggering flower formation, Penn study finds
Date:5/8/2014

bberellin-deficient breeds of rice to produce more compact plants that don't topple over in wind and rain. The new understanding of gibberellin's role gained from this study could help create plant breeds that are even more productive.

"We think it can be used to enhance yield," Wagner said. "Seeds are the product of a flower so if you want more seed you want more flowers. Being able to modulate the accumulation or degradation of gibberellin could allow one to optimize or enhance the seed set and yield in crop plants."

The Penn team plans to explore other plants to see if gibberellin operates the same way across species and in perennials as well and to further explore how different levels of the hormone trigger regulatory events that either inhibit or promote flower production.
