Isolation and identification of Desmodium root exudates from drought tolerant species used as intercrops against Striga hermonthica
Plants from the genus Desmodium, in particular D. uncinatum, are used on sub-Saharan small-holder farms as intercrops to inhibit parasitism of cereal crops by Striga hermonthica and Striga asiatica via an allelopathic mechanism. The search for Desmodium species which are adapted to more arid conditions, and which show resilience to increased drought stress, previously identified D. intortum, D....
متن کاملIdentification of Striga hermonthica-Resistant Upland Rice Varieties in Sudan and Their Resistance Phenotypes
Rice has become a major staple cereal in sub-Saharan Africa. Currently, upland rice cultivation is expanding particularly in rainfed areas where the root parasitic weed Striga hermonthica, a major constraint to cereal production, is endemic. Laboratory, pot, and semi-controlled open air experiments were performed to evaluate resistance of selected rice varieties in Sudan to a resident S. hermon...
متن کاملEffect of Seed Priming on Early Development of Sorghum (Sorghum bicolor L. Moench) and Striga hermonthica (Del.) Benth
Striga hermonthica is an obligate, root parasite, that limits cereal production in sub-Saharan Africa. Successful control depends on eliminating its seed reserves in soil, thereby preventing parasitism. Two experiments were conducted to evaluate the effects of salinity on germination traits and seedling growth of sorghum (cultivar Wad Ahmed) and S. hermonthica. The experiments were conducted in...
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 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...
