-
The most striking feature of Striga is that its seeds germinate only when they recognize the presence of the compound called strigolactone, which is secreted from the roots of host plants.

Shinjiro Yamaguchi, team leader of the Cellular Growth and Development Research Team at the RIKEN Plant Science Center, has recently clarified that strigolactone, which is also known for its role in attracting mycorrhizal fungi, is in fact a plant hormone that inhibits shoot branching.

"There is now no doubt that strigolactone is a branching-inhibiting hormone."

-
A research team at Osaka Prefecture University recently solved this mystery when they clarified that strigolactone attracts mycorrhizal fungi.

-
The secretion of strigolactone has been known for 40 years, but the question of how strigolactone is produced had remained a mystery.

-
The 2005 paper showed that strigolactone is produced from carotenoids, much like the branching-inhibiting hormone that Yamaguchi was looking for, which is produced when carotenoids are cleaved by CCD.

-
He found that almost no strigolactone was produced in D17 - or D10-deficient mutant plants, whereas large amounts of strigolactone were produced in D3-deficient mutant plants.

Studies on mutant plants provide insights into the role of strigolactone, a plant hormone that inhibits shoot branching and attracts both beneficial symbionts and damaging root parasites

-
When strigolactone was administered to mutant plants, Yamaguchi was able to verify that the excess shoot branching observed in the D17 - and D10-deficient mutant plants returned to normal, while the D3-deficient mutant plants were unaffected.

"Many researchers have been searching for plants like the D10-deficient mutants that do not produce strigolactone, because these plants cannot be parasitized by Striga."
