Special Issue Information

Dear Colleagues,

Jasmonates are key plant hormones involved in regulating growth, development, and stress responses. They play an essential role in mediating plant defense mechanisms against biotic and abiotic stresses, influencing secondary metabolism and environmental adaptation. Recent research has greatly expanded our understanding of jasmonate biosynthesis, signaling, and its interaction with other hormones. However, challenges remain in terms of fully understanding the integration of jasmonate signaling with environmental cues and other regulatory pathways. 

This Special Issue will focus on recent advancements in jasmonate research, covering topics such as jasmonate biosynthesis, signaling pathways, and their role in plant growth and stress responses. We invite contributions that explore the molecular mechanisms of jasmonates in response to environmental changes, particularly in the context of climate change. Articles may also discuss the application of jasmonate-based strategies in agriculture to enhance crop resistance and productivity. Original research, reviews, and opinion papers are welcome, contributing to a deeper understanding of jasmonate biology and its potential applications in plant science and agriculture.

In response to stresses, jasmonates increase rapidly, leading to plant resistance against necrotrophic pathogens and chewing insect herbivores. Jasmonate biosynthesis is regulated at many levels, including transcriptionally, through alternative splicing, and the phosphorylation of the 13S-lipoxygenase (LOX) that catalyzes an early step in jasmonate biosynthesis. In pepper, transcriptomic analysis of a foliar wounding time course was conducted to deepen our understanding of these regulatory mechanisms. All four CaLOXs are constitutively expressed. CaLOX2, which encodes an enzyme with a Ser in a predicted regulatory phosphosite, shows a rapid but short-lived increase in wound-induced expression. In contrast, CaLOX7, which encodes a protein with a non-phosphorylatable Ala at the phosphosite, shows higher wound-induced expression at 6 h. As well, at this timepoint, there is a predicted increase in exon 4 retention in CaLOX8 transcripts in wounded plants. ChimeraX protein modeling predicts that the retention of exon 4 may negatively affect enzyme activity, possibly by blocking access to the enzyme’s active site. The transcription, alternative splicing, and post-translational regulation of CaLOX enzymes support the dynamic fluctuations observed in the jasmonates, which increase rapidly upon wounding and return to basal levels at 6 h post-stress.

Jasmonates are lipid-derived phytohormones that regulate plant development and defense across the green lineage. Thus, understanding the intricacies of jasmonate biosynthesis and signaling is of paramount importance to improve crop yields and food safety. For the last 40 years, the canonical jasmonate biosynthetic pathway has been thoroughly dissected in angiosperms; however, only recent efforts have started to decode the alternative jasmonate biosynthetic networks that operate in bryophytes. In the nonvascular model Marchantia polymorpha, a cis-to-iso isomerization constitutes a key step in the formation of dn-iso-OPDA and Δ4-dn-iso-OPDA, the bioactive jasmonates recognized by a conserved COI1/JAZ co-receptor complex. Their biosynthesis depends on a uniquely expanded fatty acid repertoire that includes, alongside the canonical C16 and C18 omega-3 polyunsaturated fatty acids (PUFAs) found in angiosperms, substantial pools of eicosanoids such as arachidonic acid and eicosapentaenoic acid, essentially absent from flowering plants. Here we trace the jasmonate biosynthetic pathway in bryophytes step-by-step, from PUFA precursors production through lipoxygenase oxygenation and downstream reactions to the processing and catabolic modifications of bioactive compounds. By integrating current knowledge across bryophyte lineages, we identify mechanistic parallels and divergences relative to angiosperms, highlight key unresolved questions, and propose future directions for the field. Deciphering jasmonate biosynthesis in bryophytes is essential for reconstructing the evolutionary origins of jasmonate signaling and understanding how this pathway contributed to the successful colonization of land by plants.
