A comprehensive germplasm evaluation study of wheat accessions conserved in the Indian National Genebank was conducted to identify sources of rust and spot blotch resistance. Genebank accessions comprising three species of wheat-Triticum aestivum, T. durum and T. dicoccum were screened sequentially at multiple disease hotspots, during the 2011-14 crop seasons, carrying only resistant accessions...
Crop maintenance is one of the crucial factors that determine the quantity and quality of the agricultural products. Protecting crops from plant diseases is an important aspect that increases the profit of the farmer. This study aims at developing a computational model that will facilitate crop production by accurately identifying diseases that affect productivity of turmeric plants. The turmer...
background and objectives: septoria leaf blotch disease (stb) caused by the fungus mycosphaerella graminicola (fuckel) j. schroeter (anamorph: septoria tritici roberge), is one of the most destructive foliar diseases of wheat in the world, that its worldwide damage in outburst years is about 30 to 50 per cent. the pathogen is a bipolar heterotallic ascomycete that its sexual life cycle is repea...
Assortative mating promotes reproductive isolation and allows allopatric speciation processes to continue in secondary contact. As mating patterns are determined by mate preferences and intrasexual competition, we investigated male-male competition and behavioral isolation in simulated secondary contact among allopatric populations. Three allopatric color morphs of the cichlid fish Tropheus wer...
water is the most limiting factor in irrigated agriculture, mainly in mediterranean environments, as in the case of southwest spain. in this area, almond is one of the most valuable crops due to its high drought tolerance. this work examines the crop coefficients (kc) based on four drainage lysimeters installed in an experimental young almond orchard. complementary, two deficit-irrigation treat...
Ringspot symptoms in European mountain ash (Sorbus aucuparia L.), fig mosaic, rose rosette, raspberry leaf blotch, pigeonpea sterility mosaic (Cajanus cajan) and High Plains disease of maize and wheat were found to be associated with viruses that share several characteristics. They all have single-stranded multipartite RNA genomes of negative orientation. In some cases, double membrane-bound vi...
Xylella fastidiosa is a Gram-negative plant-pathogenic bacterium causing many economically important diseases, including almond leaf scorch disease (ALSD) in California. Genome information greatly facilitates research on this nutritionally fastidious organism. Here we report the complete genome sequences of two ALSD strains of this bacterium, M12 and M23.
Several leaf spotting or blotching fungal diseases occur on forest trees in Guilan province (N Iran). Some of them such as maple tar spot affect health of host trees severely, but many are of minor effect. This study was carried out to identify unknown and less known fungi causing leaf spot and leaf blotch diseases on broad leaf trees in this region. So far numerous fungi were collected. Four s...
