Fabaceae; complementary DNA; cowpeas; cultivars; drought; enzyme activity; gene expression; glutathione-disulfide reductase; leaves; metabolism; metabolites; molecular cloning; molecular weight; plant physiology; reactive oxygen species; thiols; water stress
Abstract:
... Reactive oxygen species (ROS) are commonly found in plants as natural by-products of the metabolism but their production is greatly enhanced under abiotic stresses. Particular metabolites and enzymes belonging to the ascorbate-glutathione cycle are able to scavenge these deleterious molecules and modulate the cellular redox-status. In the March issue of Journal of Plant Physiology, we have shown t ...

Abstract:
... Root colonization of plants with certain rhizobacteria, such as Pseudomonas chlororaphis O6, induces tolerance to biotic and abiotic stresses. Tolerance to drought was correlated with reduced water loss in P. chlororaphis O6-colonized plants and with stomatal closure, indicated by size of stomatal aperture and percentage of closed stomata. Stomatal closure and drought resistance were mediated by p ...

Abstract:
... Assessing the viability of a population requires understanding of the resources used by animals to determine how those resources affect long-term population persistence. To understand the true importance of resources, one must consider both selection (where a species occurs) and fitness (reproduction and survival) associated with the use of those resources. Failure to do so may result in incorrect ...

Climatologists, breeders and agronomists need tools to translate variable climatic conditions in semi-arid environments into probable performance, and to translate genotype characteristics into agro-ecological fit of cultivars. Although geographic adaptation of West African sorghum cultivars is largely related to local characteristics of the wet season, they require, in addition to drought toleran ...

Abstract:
... Water-deficit stress poses unique challenges to plant cells dependent on a hydrostatic skeleton and a polysaccharide-rich cell wall for growth and development. How the plant cell wall is adapted to loss of water is of interest in developing a general understanding of water stress tolerance in plants and of relevance in strategies related to crop improvement. Drought tolerance involves adaptations ...
