Special Issue Information

Dear Colleagues,

Plants are constantly challenged by diverse environmental stresses, including drought, salinity, extreme temperatures, heavy metals, and pathogen attacks. To survive and thrive under these adverse conditions, plants have evolved intricate signaling networks and adaptive mechanisms that regulate growth, development, and productivity. Understanding these stress responses and signaling pathways is crucial for advancing sustainable agriculture and ensuring global food security.

This Special Issue of Plants aims to bring together cutting-edge research and comprehensive reviews that deepen our knowledge of plant stress physiology, molecular signaling, and adaptive strategies. By highlighting recent advances, we seek to foster interdisciplinary dialogue and provide new insights into how plants perceive, respond to, and overcome environmental challenges. Contributions that integrate physiological, biochemical, molecular, and omics approaches are particularly welcome.

We invite researchers worldwide to submit original research articles, reviews, and perspectives that will collectively advance the field and inspire innovative solutions for crop improvement and resilience.

Abstract
Jasmonates (JAs) are a diverse group of jasmonic acid (JA)-linked metabolites, including the biosynthetic intermediate 12-oxophytodienoic acid (OPDA). Although changes in JAs have been associated with plant responses to abiotic stress, the involvement and kinetics of specific forms such as JA, JA-Ile and [...] Read more.
Jasmonates (JAs) are a diverse group of jasmonic acid (JA)-linked metabolites, including the biosynthetic intermediate 12-oxophytodienoic acid (OPDA). Although changes in JAs have been associated with plant responses to abiotic stress, the involvement and kinetics of specific forms such as JA, JA-Ile and OPDA require further clarification. This study analyzed jasmonate profiles in roots and leaves of two oat genotypes differing in drought tolerance. Jasmonates were quantified using UPLC-MS/MS, expression of key biosynthetic genes was assessed by qRT-PCR, and JA/OPDA treatments were applied to evaluate their effects on physiological and morphological responses to drought. Drought induced contrasting jasmonate dynamics in roots and leaves, with overall JA levels increasing in leaves and decreasing in roots, with genotype- and compound-specific differences. JA and JA-Ile ((+)-7-iso-jasmonoyl-L-isoleucine) showed similar trends, whereas OPDA displayed a distinct pattern. The tolerant genotype exhibited an early and marked reduction in root OPDA, while the susceptible one showed minimal change. Exogenous OPDA increased drought symptoms, reduced leaf relative water content and strongly decreased root length by limiting the formation of new thin roots. In contrast, JA application alleviated drought symptoms, reflected in a lower area under the drought progress curve, without affecting root length. Results suggest that under water deficit, reduced OPDA, likely due to its conversion into JA and JA-Ile, is associated with the development of small-diameter roots essential for maintaining water status in oat. Together, these results highlight tissue-specific differences in jasmonate dynamics during drought and show that OPDA and JA treatments lead to distinct drought-related responses in both leaves and roots.
