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 کاملStructural 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 کاملPearl Millet and Sorghum Improvement in India
The International Food Policy Research Institute (IFPRI) was established in 1975. IFPRI is one of 15 agricultural research centers that receive principal funding from governments, private foundations, and international and regional organizations, most of which are members of the Consultative Group on International Agricultural Research (CGIAR). IFPRI's research, capacity strengthening, and comm...
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 کاملPast and present dynamics of sorghum and pearl millet diversity in Mount Kenya region
Crop populations in smallholder farming systems are shaped by the interaction of biological, ecological, and social processes, occurring on different spatiotemporal scales. Understanding these dynamics is fundamental for the conservation of crop genetic resources. In this study, we investigated the processes involved in sorghum and pearl millet diversity dynamics on Mount Kenya. Surveys were co...
