Leaf extracts of 27 `Yuzu' and related acid citrus cultivars were analyzed using polyacrylamide gel electrophoresis for isozyme variation of glutamate oxaloacetate transaminase (GOT) and shikimate dehydrogenase (SDH). SDH yielded 12 different isozyme phenotypes and six cultivars were discriminated by this enzyme alone. GOT produced 10 different isozyme phenotypes and four cultivars were separat...

Maturity group (based on the number of days to maturity) is an important growth trait for determining crop productivity, but there has been no attempt to examine the effects of elevated [CO(2)] on yield enhancement of rice cultivars with different maturity groups. Since early-maturing cultivars generally show higher plant N concentration than late-maturing cultivars, it is hypothesized that [CO...

With the objective to identify previously unknown parental relationships among grapevine cultivars, 352 cultivars of Vitis vinifera L. were analyzed at 17 microsatellite loci. 29 were found to be duplicate genotypes of other cultivars. From the 323 unique genotypes, 89 possible pairs of parents were identified for 52 cultivars (i.e., each putative progeny cultivar shared at least one allele wit...

We used native polyacrylamide gel electrophoresis to identify polymorphism levels in α- and β-esterase loci from leaf tissues of Brazilian soybean cultivars for the analysis of population genetic diversity and structure, and to investigate relationships between conventional and genetically modified cultivars. The cultivars included lines developed by a soybean-grower cooperative (CD), by ...
