The relative importance of random genetic drift and local adaptation in causing population
substructuring in plant species remains an important empirical question. Here I estimate the …

Here, a complete study is described of all the genes and isoenzymes for aspartate
aminotransferase (AspAT) present in Arabidopsis thaliana. Four classes of cDNAs …

Mating systems are influenced by several ecological factors, including plant density, number
of flowers per plant, and pollinator movements. In this study, we investigated the …

Genetic variation among 12 populations of the American chestnut (Castanea dentata) was
investigated. Population genetic parameters estimated from allozyme variation suggest that …

Exclusion of combined nitrogen (NaNO3) from the growth medium caused certain changes
in metabolic processes leading to cessation in growth of the non-heterocystous, non …

Allelic variation in seedlings from 60 North American populations of the alien annual grass
Bromus tectorum was determined at 25 loci using starch gel electrophoresis. Populations …

The present investigation was carried out to study the role of calcium chloride in enhancing
tolerance and reducing cadmium toxicity in pea seedlings. Some treatment with 1 and 5 mM …

Goodyera procera is an endangered terrestrial orchid in Hong Kong. Information on its
reproductive biology and pattern of genetic variation is needed to develop efficient …

An improved genetic map of diploid (2n= 2x= 16) alfalfa has been developed by analyzing
the inheritance of more than 800 genetic markers on the F 2 population of 137 plant …

Epichloë species are endophytic symbionts of grasses which may differ in the relative
importance of their sexual or asexual life cycles. Sexual reproduction of the fungus by …
