Rice, Journal Year: 2025, Volume and Issue: 18(1)

Published: Feb. 18, 2025

Jasmonic acid (JA) signaling plays a crucial role in rice defense against the striped stem borer, Chilo suppressalis, notorious pest causing significant yield losses. This review explores current understanding of JA-mediated mechanisms rice, focusing on molecular basis, regulatory elements, and practical implications for management. JA biosynthesis pathways are induced upon C. suppressalis infestation, leading to activation various responses. These include upregulation JA-responsive genes involved production proteinase inhibitors, volatile organic compounds, other defensive compounds. The also discusses crosstalk between hormonal pathways, such as salicylic ethylene, fine-tuning Structural modifications plants, cell wall reinforcement accumulation secondary metabolites, have been highlighted key components suppressalis. Furthermore, applications this knowledge breeding insect-resistant varieties developing sustainable management strategies were explored. Future research directions proposed further elucidate complexities rice-insect interactions harness enhance crop protection.

Jasmonates Coordinate Secondary with Primary Metabolism

Metabolites, Journal Year: 2023, Volume and Issue: 13(9), P. 1008 - 1008

Published: Sept. 13, 2023

Jasmonates (JAs), including jasmonic acid (JA), its precursor 12-oxo-phytodienoic (OPDA) and derivatives jasmonoyl-isoleucine (JA-Ile), methyl jasmonate (MeJA), cis-jasmone (CJ) other oxylipins, are important in the regulation of a range ecological interactions plants with their abiotic particularly biotic environments. Plant secondary/specialized metabolites play critical roles implementing these functions JAs. Pathway transcriptional analyses have established central role JA-Ile-mediated core signaling promoting biosynthesis great diversity secondary metabolites. Here, we summarized advances JAs-induced metabolites, induced by OPDA volatile organic compounds (VOCs) CJ through independent JA-Ile. The JAs integrating coordinating primary metabolism, thereby orchestrating plant growth-defense tradeoffs, were highlighted discussed. Finally, provided perspectives on improvement adaptability resilience to changing environments production valuable phytochemicals exploiting JAs-regulated

A signaling cascade mediating fruit trait development via phosphorylation‐modulated nuclear accumulation of JAZ repressor

Journal of Integrative Plant Biology, Journal Year: 2024, Volume and Issue: 66(6), P. 1106 - 1125

Published: April 1, 2024

ABSTRACT It is generally accepted that jasmonate‐ZIM domain (JAZ) repressors act to mediate jasmonate (JA) signaling via CORONATINE‐INSENSITIVE1 (COI1)‐mediated degradation. Here, we report a cryptic cascade where JAZ repressor, FvJAZ12, mediates multiple inputs phosphorylation‐modulated subcellular translocation rather than the COI1‐mediated degradation mechanism in strawberry ( Fragaria vesca ). FvJAZ12 acts regulate flavor metabolism and defense response, was found be target of FvMPK6, mitogen‐activated protein kinase capable responding signal stimuli. FvMPK6 phosphorylates at amino acid residues S179 T183 adjacent PY residues, thereby attenuating its nuclear accumulation relieving repression for FvMYC2, which control expression lipoxygenase 3 FvLOX3 ), an important gene involved JA biosynthesis diverse array cellular metabolisms. Our data reveal previously unreported decipher links with fruit trait development.
