Responses of grapevine rootstocks to drought stress

Drought response of rootstocks is important for overall viticulture as a result of increase in water scarcity due to climate change and irrigation limitations in winegrowing region. Grapevines are generally well-adapted to arid and semi-arid climates, and they appear to primarily rely on drought avoidance mechanisms in water stress situations. In terms of the response of the grapevine to drought conditions, rootstock...

Growth and photosynthesis response of the green alga, Picochlorum oklahomensis to iron limitation and salinity stress

The extreme environment of the Great Salt Plains (GSP) results in low algal biomass, such that natural selection is likely driven by survival of multiple abiotic stresses rather than rapid growth and biotic interactions. The objective of this study was to determine the effect of combined salinity stress and iron limitation on growth and photosynthesis in the green alga, Picochlorum oklahomensis isolated from the GSP...
