Transgenic rice (Oryza sativa L.) lines were generated through particle-bombardment-mediated transformation. Hygromycin phosphotransferase (hpt) was used as a selectable marker gene on co-integrate plasmids containing either one or two unselected genes, the Bialaphos-resistance gene (bar) coding for phosphinothricin acetyltransferase and the β-glucuronidase(More)
The success of contemporary breeding programmes involving genetic engineering depends on the stability of transgene expression over many generations. We studied the stability of transgene expression in 40 independent rice plant lines representing 11 diverse cultivated varieties. Each line contained three or four different transgenes delivered by particle(More)
Bacillus thuringiensis (Bt) crystal protein genes encode insecticidal delta-endotoxins that are widely used for the development of insect-resistant crops. In this article, we describe an alternative transgenic strategy that has the potential to generate broader and more sustainable levels of resistance against insect pests. Our strategy involves engineering(More)
Potato (Solanum tuberosum L.) genotypes with relatively high yield level and resistance to the late blight disease are being developed by the International Potato Centre (CIP) and made available to developing countries. However, for effective breeding for high yield and late blight resistance, these CIP materials and locally adapted genotypes need to be(More)
Reciprocal selection is a breeding procedure for population improvement and hybrid development. Both female and male parents contribute genes to their offspring, but the influence of female parent often extends beyond simple genetic transmission. Nine parents were crossed in a full diallel and evaluated for maternal genetic effects for resistance to rice(More)
We announce the genome sequence for Xanthomonas species strain Nyagatare, isolated from beans showing unusual disease symptoms in Rwanda. This strain represents the first sequenced genome belonging to an as-yet undescribed Xanthomonas species known as species-level clade 1. It has at least 100 kb of genomic sequence that shows little or no sequence(More)
Knowledge on gene action and trait expression are important for effective breeding. The objective of this study was to determine the general combining ability (GCA), specific combining ability (SCA), maternal effects and heritability of drought tolerance, yield and yield components of candidate sweetpotato clones. Twelve genotypes selected for their high(More)
