Plant defense priming in lab and field

 0.00

Abstract: Plants can be primed for more rapid and robust activation of defense. Priming follows perception of molecular patterns of microbes or plants, recognition of pathogen-derived effectors, or colonization by beneficial microbes. However the process can also be induced by wounding or treatment with some natural or synthetic compounds (including certain fungicides and insecticides). The primed mobilization of defense is often associated with induced disease resistance, stress tolerance, and preservation of yield. Although the phenomenon has been known for decades, the molecular basis of priming is poorly understood. This article summarizes recent progress made in unraveling molecular aspects of defense priming that is the accumulation of dormant mitogen-activated protein kinases, chromatin modifications, and the activity of transcription coactivator HsfB1. It also illuminates the potential of defense priming for plant production in the field.
