Plant Biotechnology Journal, EarlyView.ABSTRACT Low temperature triggers Ca2+ signalling and reprogramming of gene expression and metabolism in plants. However, how the Ca2+ signal is transduced to the downstream metabolic pathways remains unknown. The involvement of a cold‐induced calmodulin‐like protein, MfCML50, from Medicago falcata in regulation of cold tolerance was examined in the ...

Multigene families encode the major enzymes of antioxidant metabolism in Eucalyptus grandis L
Genetics and Molecular Biology, 2005 Antioxidant metabolism protects cells from oxidative damage caused by reactive oxygen species (ROS). In plants, several enzymes act jointly to maintain redox homeostasis.

Plant Biotechnology Journal, EarlyView.ABSTRACT Drought is the major abiotic stress threatening global crop yields, thus identifying potential candidates with promising breeding value has become a central goal of current breeding programmes. Here, we found that miR164b functions as a negative regulator in plant drought tolerance, whose expression is dramatically inhibited under drought ...

Biochemical responses of Hyacinth bean (Lablab purpureus) to salinity stress [PDF]
, 2010 Effect of salinity on Hyacinth bean, Lablab purpureus (HA-4 cultivar) was evaluated in 10-day old seedlings with 100-500 mM NaCl over 72 h of exposure. The stress reduced dry and fresh wt., leaf surface area, root and shoot length, total chlorophyll,

Plant Biotechnology Journal, EarlyView.ABSTRACT Oomycete pathogens secrete hundreds of RXLR effectors into plant cells to modulate host immunity by targeting diverse plant proteins. Here, we report that the Peronophythora litchii RXLR effector PlAvh133 acts as a virulence factor and targets the litchi glycolate oxidase (GLO) LcGLO1, a key enzyme in photorespiration, thereby suppressing ...
