Strigolactones (With Shinjiro Yamaguchi)
Strigolactones (SLs) are multifunctional hormones that contribute to the
control of shoot branching, and serve as signals between plants and
arbuscular mycorrhizal fungi and between host plants and parasitic Striga
plants. They are produced in minute quantities and so studying
strigolactones has been difficult. Strigolactone research has benefited
from the identification of pea, Arabidopsis and rice mutants
affected in SL synthesis or signaling. Because they contribute to
beneficial symbiotic interactions with mycorrhizal fungi, as well as
detrimental interactions with parasitic plants, understanding how SLs
are produced and act is a high priority particularly in tropical regions
where Striga parasites are endemic. Progress in the past
decade has been rapid, but we have much still to learn about this
fascinating family of hormones. First posted April 25, 2011, revised by Vagner Benedito ( November 30, 2012, revised November 2, 2015.
