The present study reports the setting up of Diversity Arrays Technology (DArT) markers in olive (Olea europaea L.). Two genomic representations were generated using the PstI/. TaqI combination. A first one was aimed to cover the variability available at the World Olive Germplasm Bank (WOGB) and it was based on DNA from 87 olive cultivars carefully selected from the WOGB to represent the olive variability.
Phytophthora infestans (Mont.) de Bary, the causal organism of late blight, is economically the most important pathogen of potato and resistance against it has been one of the primary goals of potato breeding. Some potentially durable, broad-spectrum resistance genes against this disease have been described recently
Turf-type tall fescue (Festuca arundinacea Schreb.) germplasm available both commercially and in cultivar trials is surprisingly similar in quality and performance. To test genetic diversity within this germplasm, Diversity Arrays Technology (DArT) was used to detect DNA polymorphism among 93 entries from the 2006 National Turfgrass Evaluation Program tall fescue test in Riverside, CA.
Genomic selection (GS) or genome-wide selection (GWS) was a landmark proposal made 11 yr ago providing a genome-wide paradigm for marker-assisted selection (MAS) in plants and animals (Meuwissen et al., 2001; Goddard & Hayes, 2009)
Solanum × michoacanum (Bitter.) Rydb. is a diploid, 1 EBN (Endosperm Balance Number) nothospecies, a relative of potato originating from the area of Morelia in Michoacán State of Mexico that is believed to be a natural hybrid of S. bulbocastanum × S. pinnatisectum. Both parental species and S. michoacanum have been described as sources of resistance to Phytophthora infestans (Mont.) de Bary
The wheat (Triticum aestivum L.) cultivar ‘Stephens’ has been grown commercially in the USA Pacific Northwest for 30 years. The durable resistance of ‘Stephens’ to stripe rust (Puccinia striiformis f. sp. tritici) was believed to be due to a combination of seedling and adult plant resistance genes.
The genetic associations and differences of four protein fractions were investigated in Tibetan wild barley. Albumin, globulin and hordein contents were under genetic control probably via multiple genes/quantitative trait loci. A correlation analysis showed that globulin was significantly associated with albumin, glutelin and hordein, while hordein was closely correlated with glutelin.
