Jasmonates, as a plant endogenous hormone, can induce the biosynthesis of terpenoids, alkaloids and flavonoids and other medicinal active ingredients, and play an important role in the plant secondary metabolic process. The tanscription factors can activate the expression of multiple genes in the biosynthesis of plant secondary metabolites by binding the cis-elements of the target genes. Then, it effectively activates or inhibits the activities of the enzymes on the biosynthesis of plant secondary metabolites, further regulate specific biosynthesis and accumulation of secondary metabolites. Here, We review recent major progresses regarding the regulation of secondary metabolites by JAs-responsive transcription factors (TFs) (including AP2/ERFs, bHLH, MYB and WRKY). That provides suggestions for further analysis of jasmonic acid signaling pathway and regulation of secondary metabolism, and explores the potential value of transcription factor in improving the medicinal active ingredients.

Militarine is a monomer molecule with abundant and distinctive biological properties, also the lead member of secondary metabolites in Bletilla striata, while its biosynthesis mechanism is still unknown. To improve the production efficiency of militarine, sodium acetate and salicylic acid (SA) were introduced as elicitors into the suspension-cultured callus of B. striata.

Ink disease caused by the hemibiotrophic root pathogen Phytophthora cinnamomi (Pc) is devastating for the European chestnut (Castanea sativa), unlike Asian chestnuts and interspecific hybrids which are resistant to Pc. The role that hormone responses play for Pc resistance remains little understood, especially regarding the temporal regulation of hormone responses. We explored the relationship between changes in tree health and physiology and alterations in leaf and root phytohormones and primary and secondary metabolites during compatible and incompatible Castanea spp.

Root-associated endophytic fungi can create symbiotic relationships with trees to enhance stress tolerance, but the underlying mechanisms, especially with regard to waterlogging tolerance, remain unclear. This study aimed to elucidate the effects of Funneliformis mosseae and Serendipita indica on the growth, root cross-section structure, and root transcriptional responses of peach under waterlogging stress, with a focus on polyamine and proline metabolism. Genes and transcription factors associated with secondary cell wall biosynthesis were selected, and their expression profiles were analyzed.
