WebbWith the advent of facile gene mapping and cloning, allied to knowledge of plant resistance gene structure, renewed efforts are leading to mapping and isolation of new sources of late blight resistance in potato wild species, many of which are being performed under the auspices of the BIOEXPLOIT project (Sub-project 2). WebbGenetic diversity and relationships of 40 accessions of Ipomoea, representing ten species of series Batatas, were examined using ISSR markers and restriction-site variation in four non-coding regions of chloroplast DNA. A total of 2071 ISSR fragments were generated with 15 primers in these accessions and, on average, 52 bands per accession were … slowfox tanzmusik by youtube
