Plant Defense Genes against Biotic Stresses

Two other reviews are focused on specific players involved in plants’ resistance to pathogens: (i) host proteases located at different subcellular compartments that act as integral enzymes of the plant immune system and regulate hypersensitive response, pathogen recognition, priming, and peptide hormone release [5] and (ii) NOD-like receptors, one of the largest gene families in plants subjected to rapid evolution, that can induce an autoimmunity state that strongly affects plant growth and yield [6]. [10] show that soluble sugar content was increased in tomato leaves during early infection by root-knot nematodes as a result of the activation of photosynthesis or the hydrolysis of starch, whereas an increase in sugar in the roots is a consequence of sugar translocation from source to sink tissue via transporters. [...]authors determine the function of sugar transporter genes in infected-tomato. The ectopic expression of an ethylene response transcription factor (VaERF20) from a Chinese wild Vitis genoptype in the model plant Arabidopsis thaliana displays enhanced resistance to Botrytis cinerea and to the bacterium Pseudomonas syringae pv. tomato DC3000 by activating salycilic acid and jasmonic acid/ethylene signaling [20].
