Abstract:

The plants can trigger a series of defensive response against the attack from various pathogens, which includes a variety of signal reactions, such as the generation, transduction and interaction of signals, and then a series of defensive gene expression and metabolic changes, and finally the plants acquire resistance. During the process of defensive reactions, signaling molecules play important roles, such as plant hormones (salicylic acid, jasmonic acid, ethylene and abscisic acid), the second messengers (Ca2+, ROS and NO), low molecular peptide (glutathione), lipids and sugars. Significant progresses have been made in disease resistance response mediated by these signaling molecules in recent years. This paper reviewed the research progress and prospected the future research works.
