Jasmonic acid signaling and its research progress in woody plants

As an important plant endogenous hormone, jasmonic acids are widely involved in many biological processes, such as regulating plant growth and development, defense response, flowering time. Moreover, many studies have shown that JAs regulates fruit quality and metabolite content. This paper summarized the effects of jasmonic acid signal on stress response, flowering time regulation, floral organ development, color quality and metabolic components of plants, expounded the latest research progress of jasmonic acid signal in plants, especially in woody plants. We proposed that the study of jasmonic acid signaling should be biased towards economic plants, expanding screening of interaction factors, taking the differences of different genotypes and multiple biological pathways into account in order to fully reveal the diversity of jasmonate signal regulation pathway and the complexity of transduction mechanism, and explore its potential function in forest.
