“…Contrarily, JA was much more bioactive than indole-3-carbaldehyde and 3-ICA against Bgt E21, and the disease severity of Bgt E21 decreased significantly with the concentration increase of JA treatment ( Table 2 ). In plants, the plant hormone JA and its derivatives are involved in regulating a diverse set of processes including cellular development, defense, and resistance to both abiotic and biotic stress ( Ruan et al., 2019 ; Gomi, 2021 ). For instance, when applied to plants, the JA-derivative lasiojasmonate A (LasA), isolated from Lasiodiplodia mediterranea , a pathogen of grapes, induces many JA-regulated response in planta at both the genetic and physical level ( Chini et al., 2018 ).…”

The discovery of natural bioactive compounds from endophytes or medicinal plants against plant diseases is an attractive option for reducing the use of chemical fungicides. In this study, three compounds, indole-3-carbaldehyde, indole-3-carboxylic acid (3-ICA), and jasmonic acid (JA), were isolated from the EtOAc extract of the culture filtrate of the endophytic fungus Lasiodiplodia pseudotheobromae LPS-1, which was previously isolated from the medicinal plant, Ilex cornuta. Some experiments were conducted to further determine the antifungal activity of these compounds on wheat powdery mildew. The results showed that JA was much more bioactive than indole-3-carbaldehyde and 3-ICA against Blumeria graminis, and the disease severity caused by B. graminis decreased significantly with the concentration increase of JA treatment. The assay of the interaction of 3-ICA and JA indicated that there was a significant synergistic effect between the two compounds on B. graminis in each of the ratios of 3-ICA to JA (3-ICA:JA) ranging from 1:9 to 9:1. When the compound ratio of 3-ICA to JA was 2:8, the synergistic coefficient was the highest as 22.95. Meanwhile, a histological investigation indicated that, under the treatment of JA at 500 μg/ml or 3-ICA:JA (2:8) at 40 μg/ml, the appressorium development and haustorium formation of B. graminis were significantly inhibited. Taken together, we concluded that JA plays an important role in the infection process of B. graminis and that 3-ICA as a synergist of JA enhances the antagonism against wheat powdery mildew.

“…Studies have shown that MeJA can promote terpene biosynthesis in plants and is involved in the stomatal closure of cucumbers [ 11 ]. Furthermore, relevant studies have shown that MeJA can regulate the respiratory metabolism, carotenoid synthesis, ethylene synthesis, phenylpropane metabolism, and anthocyanin metabolism of fruit and vegetable products.…”

The plant hormone jasmonic acid plays an important role in plant growth and development, participating in many physiological processes, such as plant disease resistance, stress resistance, organ development, root growth, and flowering. With the improvement in living standards, people have higher requirements regarding the quality of vegetables. However, during the growth process of vegetables, they are often attacked by pests and diseases and undergo abiotic stresses, resulting in their growth restriction and decreases in their yield and quality. Therefore, people have found many ways to regulate the growth and quality of vegetable crops. In recent years, in addition to the role that JA plays in stress response and resistance, it has been found to have a regulatory effect on crop quality. Therefore, this study aims to review the jasmonic acid accumulation patterns during various physiological processes and its potential role in vegetable development and quality formation, as well as the underlying molecular mechanisms. The information provided in this manuscript sheds new light on the improvements in vegetable yield and quality.

“…MeJAresponsive element is the most abundant element, containing 350 instances. As we all know, Methyl jasmonic acid regulates physiological processes such as plant growth and development, especially the response of plants to biotic and abiotic stresses [30]. DnMYB23 contained 24 MeJA-responsive elements in its 2-k upstream regulatory region.…”

R2R3-MYB is one of the largest and most important gene families, participating in the regulation of plant growth and development and response to abiotic stresses. However, the function of R2R3-MYB genes in Dendrobium nobile remains largely unknown. Here, a comprehensive genome-wide analysis of D. nobile R2R3-DnMYBs was performed, investigating phylogenic relationships, gene structures, motif composition, chromosomal locations, collinearity analysis, and cis-acting elements. Totally, 125 DnMYB genes were identified in the D. nobile genome, and they could be subdivided into 26 groups by further divided through phylogenetic analysis. Most genes with similar exon-intron structures and motif compositions in eaach subgroup exhibited similar functions. All of DnMYB genes were mapped on 19 chromosomes with the co-linearity relationship. Moreover, their expression patterns were analyzed in various tissues and abiotic stresses. The results showed that DnMYBs were significantly differential expressed in different tissues, following abiotic stresses and phytohormone treatments, indicating their possible roles in biological processes and some abiotic stress tolerance and adaptation. This work provides a comprehensive understanding of the R2R3-MYB family of D. nobile, and lays a foundation for future research on the potential function of DnMYB gene in the growth and development of D. nobile.
