Branching, or bushiness in plants is controlled by breakdown of the hormone strigolactone by carboxylesterase enzymes. New work at UC Davis reveals the structure of two of these enzymes in plants ...

“We have been studying a new plant hormone signal, strigolactone, that governs numerous processes of growth and development including branching and root architecture.” The work stems from a study by ...

For many plants, more branches means more fruit. But what causes a plant to grow branches? New research from the University of California, Davis shows how plants break down the hormone strigolactone, ...

Unlocked enzyme structure shows how strigolactone hormone controls plant growth Peer-Reviewed Publication. University of California - Davis ...

Direct conversion of carlactonoic acid to orobanchol by cytochrome P450 CYP722C in strigolactone biosynthesis. Science Advances , 2019; 5 (12): eaax9067 DOI: 10.1126/sciadv.aax9067 Cite This Page : ...

Traditional methods to study strigolactone, ... sufficient quantities of 16-OH-CLA—thanks to the microbial cell factory—allowed the team to uncover its precise structure for the first time.

The structure revealed a fragment of the hormone covalently bound to two of the catalytic amino acids of AtD14. The authors' observations imply that, after the hormone strigolactone binds to AtD14 ...

Unlocked enzyme structure shows how strigolactone hormone controls plant growth. As sessile organisms, plants have to continually adapt their growth and architecture to the ever-changing environment.

As such, this sulfotransferase is probably involved in stereocontrol of the strigolactone molecular structure and its functional deletion results in the preferential production of orobanchol in ...

Crop breeding and agriculture are two areas that are likely to enjoy significant benefits from the ability to control strigolactone levels. “Knowing the full biosynthesis pathway is a crucial step in ...
