“…Based on the results of this study, it was found that most of the ethylene-related DEGs were upregulated in stages 1 and 2 ( Figure 9 ), which may be related to the promotion of growth in the early post-germination stages. Studies have reported that brassinosteroid mainly promotes cell division and cell elongation (Pacifici et al, 2015 ), and that jasmonic acid is mainly involved in stress response (Zhao et al, 2019 ). Most of the DEGs related to brassinosteroid and jasmonic acid were increased in stage 5 ( Figure 9 ), indicating that other than growth promotion, there may have been anti-stress involved in stage 5.…”

The wild population of Madhuca pasquieri (Dubard) H. J. Lam is currently dwindling; its understory seedlings are rare, and there is a lack of molecular studies, which impedes the conservation of this species. This study exploited second-generation sequencing and widely targeted metabolomics analysis to uncover the dynamic changes in differentially expressed genes (DEGs) and differentially accumulated metabolites (DAMs) in five post-germination stages of M. pasquieri whole organism. Notably, the weighted gene co-expression network analysis (WGCNA), transcriptome, and metabolome association analyses all indicated significant enrichment of the flavonoid biosynthesis pathway in stage 4 (two-leaf), and an upregulation of the genes encoding flavonol biosynthesis in this stage. In stage 5 (nine-leaf), the flavonols were significantly accumulated, indicating that the changes in metabolites were driven at the transcript level. According to the significant changes in gene expression encoding auxin transport carriers and their correlation with flavonols during stage 5, the flavonols were speculated to have a direct inhibitory effect on the expression of PIN4 encoding gene, which may inhibit the process of polar auxin transport. The results provided important insights into the molecular network relationships between the transcription and metabolism of this rare and endangered species during the post-germination stages and explained the reasons for the slow growth of its seedlings at the molecular level.

“…In another study, it showed that JA boosted the biomass production of rice but inhibited the effect of salt which was present in water or soil [57,58,104]. In Pisum sativum, the JA application improved the profile of protein synthesis against salt stress [54,55].…”

“…Many investigations have been conducted to unravel the signaling pathway of JA in plants. It is evident from studies that in response to abiotic stress, there is a prompt induction of genes associated with the synthesis of JA, leading to the activation of the plant's defense mechanism through the regulated accumulation of JA within plant cells [47,[57][58][59]. There are specific stress-responsive genes that switch on upon exposure to stress.…”

“…While numerous HMs, like Cd, Pb, and Hg, are not necessary for plant growth, others including Fe, Mn, Cu, Mo, and Zn are required micronutrients for plant growth but have adverse effects on plant development at high concentrations [34,121]. In another study [57,122], heavy metals are considered highly poisonous for the growth of plants because these metals/metalloids are present in the environment and are highly absorbable when present in soil. These elements combine with water molecules and penetrate into root cells via micropores in root hairs.…”

“…JA plays a crucial role in various plant species to tackle the detrimental effects caused by heavy metal stress [50]. The application of JA has reduced the metal-induced stress in pigeon peas [57,122]. The elevation in endogenous JA levels is directly proportional to the effects caused by heavy metal stress.…”

Plants, being sessile, have developed complex signaling and response mechanisms to cope with biotic and abiotic stressors. Recent investigations have revealed the significant contribution of phytohormones in enabling plants to endure unfavorable conditions. Among these phytohormones, jasmonic acid (JA) and its derivatives, collectively referred to as jasmonates (JAs), are of particular importance and are involved in diverse signal transduction pathways to regulate various physiological and molecular processes in plants, thus protecting plants from the lethal impacts of abiotic and biotic stressors. Jasmonic acid has emerged as a central player in plant defense against biotic stress and in alleviating multiple abiotic stressors in plants, such as drought, salinity, vernalization, and heavy metal exposure. Furthermore, as a growth regulator, JA operates in conjunction with other phytohormones through a complex signaling cascade to balance plant growth and development against stresses. Although studies have reported the intricate nature of JA as a biomolecular entity for the mitigation of abiotic stressors, their underlying mechanism and biosynthetic pathways remain poorly understood. Therefore, this review offers an overview of recent progress made in understanding the biosynthesis of JA, elucidates the complexities of its signal transduction pathways, and emphasizes its pivotal role in mitigating abiotic and biotic stressors. Moreover, we also discuss current issues and future research directions for JAs in plant stress responses.
