Sorghum [Sorghum bicolor (L.) Moench] is ranked as the fifth most important grain crop and serves as a major food staple and fodder resource for much of the world, especially in arid and semi-arid regions. The recent surge in sorghum research is driven by its tolerance to drought/heat stresses and its strong potential as a bioenergy feedstock. Completion of(More)
Peanut genotypes from the US mini-core collection were analysed for changes in leaf proteins during reproductive stage growth under water-deficit stress. One- and two-dimensional gel electrophoresis (1- and 2-DGE) was performed on soluble protein extracts of selected tolerant and susceptible genotypes. A total of 102 protein bands/spots were analysed by(More)
ABSTRACT Aflatoxin (AF) and sterigmatocystin (ST) are toxic secondary metabolites produced by the same biochemical pathway found in several Aspergillus spp. The expression of the homologous ST/AF structural gene, stcU in A. nidulans and ver-1 in A. parasiticus, was affected by external pH of liquid growth media. Both stcU and ver-1 mRNAs appeared earlier(More)
lecular markers within mapping populations (Wendel and Parks, 1984; Torres et al., 1985; McCouch et al., Molecular tools have not identified the gene(s) governing apomixis 1988; Paterson et al., 1988, 1991; Saito et al., 1991; Lytnor have they been used to successfully transfer the trait to important, sexually reproducing food crops. Several molecular(More)
Several lines of evidence have indicated that lipoxygenase enzymes (LOX) and their products, especially 9S- and 13S-hydroperoxy fatty acids, could play a role in the Aspergillus/seed interaction. Both hydroperoxides exhibit sporogenic effects on Aspergillus spp. (Calvo, A., Hinze, L., Gardner, H.W. and Keller, N.P. 1999. Appl. Environ. Microbiol. 65:(More)
Since Upland cotton (Gossypium hirsutum) is known to have relatively low levels of genetic diversity, a better understanding of variation and relationships among possible sources of novel genes would be valuable. Therefore, analysis of genetic variation of the genus Gossypium, especially the diploids, which are the putative donors of the A and D genomes for(More)
Segregation of resistance to Meloidogyne arenaria in six BCF peanut breeding populations was examined in greenhouse tests. Chi-square analysis indicated that segregation of resistance was consistent with resistance being conditioned by a single gene in three breeding populations (TP259-3, TP262-3, and TP271-2), whereas two resistance genes may be present in(More)
The small genome of sorghum (Sorghum bicolor L. Moench.) provides an important template for study of closely related large-genome crops such as maize (Zea mays) and sugarcane (Saccharum spp.), and is a logical complement to distantly related rice (Oryza sativa) as a "grass genome model." Using a high-density RFLP map as a framework, a robust physical map of(More)
The sorghum [Sorghum bicolor (L.) Moench] inbred line BTx623 has served as a parent for development of several mapping populations, also providing a source for the generation of DNA libraries for physical mapping, and as the inbred line selected for sorghum genome sequencing. Since genetic mapping, physical mapping and genome sequencing are all based on the(More)
