| dc.description.abstract | Strigolactones released from plant rootstrigger both seed germination of parasitic weeds such
as
Striga
spp. and hyphal branching of the symbionts arbuscular mycorrhizal (AM) fungi.
Generally, strigolactone composition in exudates is quantitatively and qualitatively different
among plants, which may be involved in susceptibility and host specificity in the parasite
–
plant
interactions. We hypothesized that difference in strigolactone composition would have a
significant impact on compatibility and host specificity/preference in AM symbiosis.
Strigolactones in root exudates of
Striga
-susceptible (Pioneer 3253) and -resistant (KST 94)
maize (
Zea mays
) cultivars were characterized by LC
-
MS/MS combined with germination assay
using
Striga hermonthica
seeds. Levels of colonization and community compositions of AM
fungi in the two cultivars were investigated in field and glasshouse experiments.
5-Deoxystrigol was exuded exclusively by the susceptible cultivar, while the resistant cultivar
mainly exuded sorgomol. Despite the distinctive difference in strigolactone composition, the
levels of AM colonization and the community compositions were not different between the
cultivars.
The present study demonstrated that the difference in strigolactone composition has no
appreciableimpactonAMsymbiosis,atleastinthetwomaizecultivars,andfurthersuggeststhat
the traits involved in
Striga
