Abstract:
... Two diploid sugar beet genotypes of agronomical importance were transformed using Agrobactrium tumefaciens harboring pBI35Scry containing a synthetic cry1Ab gene. Leaf blade with attached shoot bases, a highly regenerative tissue, were used as explant substratum for transformation. PCR screening with cry1Ab-specific primers showed the presence of transgene in more than 50% of the regenerated kanam ...

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 ...

Abstract:
... Ordering dominant markers in F₂ populations is considered a difficult problem. The difficulties arise from the fact that recombinations cannot be observed directly from the data. In general, the multi-point maximum likelihood would be the appropriate criterion for ordering markers. This criterion takes into account all available information present in marker data. However, calculation of multi-poi ...

Abstract:
... The mechanism that controls the proportion of cannabichromene (CBC), a potential pharmaceutical, in the cannabinoid fraction of Cannabis sativa L. is explored. As with tetrahydrocannabinol (THC) and cannabidiol (CBD), CBC is an enzymatic conversion product of the precursor cannabigerol (CBG). CBC is reported to dominate the cannabinoid fraction of juveniles and to decline with maturation. This ont ...
