Structural basis of unique ligand specificity of KAI2-like protein from parasitic weed Striga hermonthica
The perception of two plant germination inducers, karrikins and strigolactones, are mediated by the proteins KAI2 and D14. Recently, KAI2-type proteins from parasitic weeds, which are possibly related to seed germination induced by strigolactone, have been classified into three clades characterized by different responses to karrikin/strigolactone. Here we characterized a karrikin-binding protei...
متن کاملHorizontal 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 کاملidentification of new maize inbred lines with resistance to striga hermonthica (del.) benth.
striga hermonthica is a noxious, obligate hemi-parasite of cereal grasses that causes severe grain yield loss in susceptible maize cultivars in africa. the development of host plant resistance is one of the most practical stiga control strategies. in this study experiments on 36 maize inbred lines were conducted in pots and in field during the two rainy seasons of 2009 at kibos and alupe statio...
متن کاملIssn: 1992-1705
Striga hermonthica is a widely spread root parasitic weed on cereals in Sub Saharan Africa including Sudan. The most important hosts comprise sorghum, millet and sugar cane. Host specificity and existence of two distinct strains on sorghum and millet were previously reported. Reports on a third strain specific to maize are controversial. The present study was undertaken to investigate anatomica...
متن کاملResistance to Striga hermonthica in Wild Accessions of the Primary Gene Pool of Pennisetum glaucum.
ABSTRACT Resistance to Striga hermonthica in 274 wild Pennisetum glaucum subsp. monodii and stenostachyum accessions was evaluated at Samanko, Mali in 1997 and 1998, and at Cinzana, Mali and Sadoré, Niger in 1998. Data recorded included number of striga plants per plot at least three times during the season, date of striga emergence, number of Pennisetum plants, Pennisetum anthesis date, and do...
