Horizontal gene transfer by the parasitic plant Striga hermonthica.
Horizontal gene transfer has been postulated to occur between crops to co-occurring parasitic plants, but empirical evidence has been lacking. We present evidence that an HGT event moved a nuclear monocot gene into the genome of the eudicot parasite witchweed (Striga hermonthica), which infects many grass species in Africa. Analysis of expressed sequence tags revealed that the genome of S. herm...
متن کاملThe strigolactone germination stimulants of the plant-parasitic Striga and Orobanche spp. are derived from the carotenoid pathway.
The seeds of parasitic plants of the genera Striga and Orobanche will only germinate after induction by a chemical signal exuded from the roots of their host. Up to now, several of these germination stimulants have been isolated and identified in the root exudates of a series of host plants of both Orobanche and Striga spp. In most cases, the compounds were shown to be isoprenoid and belong to ...

متن کاملEffect of Inoculation with Klebsiella oxytoca ‘10 mkr 7’ on Striga Suicidal Germination in Zea mays
The Striga species are obligate root parasitic plants. Plant growth promoting rhizobacteria could enhance Striga suicidal germination. In screen-house studies we quantified the effect of bacterial inoculation with increasing maize plant density on the parasitic weed Striga hermonthica. The design used was a randomized complete block with a factorial design (4 plant density levels, 2 S. hermonth...
متن کاملA Taylor-Made Design of Phenoxyfuranone-Type Strigolactone Mimic
Strigolactones are a class of plant hormones that inhibit axillary bud outgrowth and are released from plant roots to act as a rhizosphere communication signal. The Orobanchaceae parasitic plant Striga hermonthica perceives strigolactone as its germination signal, indicating host presence. After germination, the Striga plant parasitises the host plant and suppresses host growth by draining phot...
