Transcriptomic Study of Treated with the Bacterial Protein CspD Reveals Some Specific Abiotic Stress Responses.

The ability of a cold-shock protein CspD from to protect both dicots and monocots against various pathogens is well confirmed under both greenhouse and field conditions; however, the molecular basis of this phenomenon at the transcriptomic level still remains unexplored. Expression profiles of some marker genes associated with SAR/ISR nonspecific resistance pathways and ROS scavengers were examined in CspD-treated plants, and the RNA-seq analysis of CspD-treated plants was first carried out. The ISR markers PDF1.

Pre-illumination of rice blast conidia induces tolerance to subsequent oxidative stress.

Many environmental factors, alone or combined, affect organisms by changing a pro-/antioxidant balance. Here we tested rice blast fungus (Magnaporthe oryzae) for possible cross-adaptations caused by relatively intense light and protecting from artificially formed reactive oxygen species (ROS) and ROS-dependent fungitoxic response of the host plant. Spore germination was found to be suppressed under 4-h and, to larger extent, 5-h illumination.
