Polygalacturonase-inhibitor proteins in pearl millet: possible involvement in resistance against downy mildew.
Polygalacturonase-inhibitor protein (PGIP) is a defense protein found in plant cell walls. It prevents the degradation of pectin by modulating the endo-polygalacturonase activity. The present study has used heterologous anti-bean PGIP probes to investigate the role of PGIP in pearl millet [Pennisetum glaucum (L) R. Br.] resistance against downy mildew caused by oomycete pathogen Sclerospora gra...
متن کاملGene Effects Controlling Heritability of Downy Mildew Resistance in Nigerian Elite Pearl Millet Lines
Downy mildew disease caused by the fungus Sclerospora graminicola Schroet, causes yield losses across the millet growing zones of Nigeria. Identification of the source of resistance and gene actions controlling resistance is useful in developing appropriate breeding strategies. Therefore there was need to study downy mildew resistance in Nigerian elite pearl millet lines. Five pearl millet pare...
متن کاملEvaluation of Pearl Millet Male-sterile Lines and their Maintainers for Resistance to Downy Mildew and Smut
Downy mildew caused by Sclerospora graminicola (Sacc.) Schroët. and smut caused by Moesziomyces penicillariae (Bref.) Vanky are the most important diseases (in that order) limiting the productivity of pearl millet [Pennisetum glaucum (L.) R. Br.] in Asia and Africa (Thakur et al. 1992; Singh et al. 1993). These diseases are more serious on commercial F1 hybrids than on open-pollinated varieties...
متن کاملElicitation of resistance and associated defense responses in Trichoderma hamatum induced protection against pearl millet downy mildew pathogen
Endophytic Trichoderma hamatum UoM 13 isolated from pearl millet roots was evaluated for its efficiency to suppress downy mildew disease. Under laboratory conditions, T. hamatum seed treatment significantly enhanced pearl millet seed germination and seedling vigor. T. hamatum seed treatment resulted in systemic and durable immunity against pearl millet downy mildew disease under greenhouse and ...
متن کاملTotal crude protein extract of Trichoderma spp. induces systemic resistance in pearl millet against the downy mildew pathogen
Several proteins and peptides of microbial origin are reported for their elicitor properties, which play a vital role in the development of local and systemic resistances in plants. In this study, the efficacy of total crude proteins (TCP) extracted from six different Trichoderma spp. (T. asperellum, T. harzianum, T. atroviride, T. virens, T. longibrachiatum, and T. brevicompactum) was evaluate...
