Osmotic stress-induced polyamine oxidation mediates defence responses and reduces stress-enhanced grapevine susceptibility to Botrytis cinerea.

abstract：:To obtain and concentrate reduced N from the environment, plants have evolved a diverse array of adaptations to utilize soil, biotic and atmospheric N. In symbiotic N(2)-fixing systems the potential for oversupply exists and regulation of activity to match demand is crucial. N status in plants is likely to be most str...
