Arachis hypogaea; peanuts; disease resistance; Sclerotinia minor; blight; fungal diseases of plants; genetic markers; microsatellite repeats; polymerase chain reaction; DNA primers; genotype
Abstract:
... The production of cultivated peanut, an important agronomic crop throughout the United States and the world, is consistently threatened by various diseases and pests. Sclerotinia minor Jagger (S. minor), the causal agent of Sclerotinia blight, is a major threat to peanut production in the Southwestern US, Virginia and North Carolina. Although information on the variability of morphological traits ...

Abstract:
... Fusarium head blight (FHB), caused primarily by Fusarium graminearum (Schwabe), is an important wheat disease. In addition to head blight, F. graminearum also causes Fusarium seedling blight (FSB) and produces the mycotoxin deoxynivalenol (DON) in the grain. The objectives of this study were: (1) to compare the relationship between resistance of wheat lines to F. graminearum in the seedlings and s ...

Abstract:
... For breeding potato varieties resistant to late blight, identification of resistance genes to Phytophthora infestans (Rpi genes) is essential. Introduction of Rpi genes from wild Solanum species into cultivated potato is likely to be a good method to achieve durable resistance to P. infestans. In this study, we identified two Rpi genes (Rpi-ber1 and Rpi-ber2) derived from two different accessions ...
