Evaluation 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 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 کاملDraft genome sequence of Sclerospora graminicola, the pearl millet downy mildew pathogen
Sclerospora graminicola pathogen is the most important biotic production constraints of pearl millet in India, Africa and other parts of the world. We report a de novo whole genome assembly and analysis of pathotype 1, one of the most virulent pathotypes of S. graminicola from India. The draft genome assembly contained 299,901,251 bp with 65,404 genes. This study may help understand the evoluti...
متن کاملPolygalacturonase-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 کاملPlasmon Mutations in Cytoplasmic Male-Sterile Pearl Millet, PENNISETUM TYPHOIDES.
Spontaneous mutations from sterile to fertile were demonstrated in four different cytoplasmic male-sterile stocks of pearl millet. One stock, ASM-3, was of African origin, and the other three, LMS-1A, ASM-5, and ASM-7, all had the same cyptoplasm of Indian origin, but differed in nuclear make-up. These reversions were shown to be plasmon mutations, rather than genic in nature. ASM-3 mutated at ...
