“…These proteins are critical for protein-protein interactions with COI1, which creates the COI1-JA-Ile-JAZ co-receptor complex with the JA-Ile (jasmonoyl-L-isoleucine) ligand and then forms the COI1-JAZ co-receptor complex with the COI1-JA-Ile-JAZ co-receptor complex ( Chini et al., 2007 ; Thines et al., 2007 ; Yan et al., 2007 ; Bai et al., 2011 ). The sensing of JA-Ile by the COI1-JAZ co-receptor in the plant body causes stress reactions ( Saito et al., 2021 ). JAZ1-7, 9-12 mutations in Arabidopsis improve JA responses while suppressing COI1 phenotypes in flowering time, rosette expansion, and defense ( Liu et al., 2021 ).…”

Plant-specific TIFY [TIF(F/Y)XG] proteins serve important roles in the regulation of plant stress responses. This family encodes four subfamilies of proteins, JAZ (JASMONATE ZIM-domain), PPD (PEAPOD), ZML (Zinc-finger Inflorescence-like), and TIFY. In this work, a total of 16 JAZ, 3 PPD, 7 ZML, and 2 TIFY genes were found in cassava (Manihot esculenta Crantz) at the genome-wide level. The phylogenetics, exon-intron structure, motif organization, and conserved domains of these genes were analyzed to characterize the members of the JAZ, PPD, and ZML subfamilies. Chromosome location and synteny analyses revealed that 26 JAZ, PPD, and ZML genes were irregularly distributed across 14 of the 18 chromosomes, and 18 gene pairs were implicated in large-scale interchromosomal segmental duplication events. In addition, JAZ, PPD, and ZML gene synteny comparisons between cassava and three other plant species (Arabidopsis, Populus trichocarpa, and rice) uncovered vital information about their likely evolution. The prediction of protein interaction network and cis-acting elements reveal the function of JAZ, PPD, and ZML genes. Subsequently, expression patterns of JAZ, PPD, and ZML genes were validated by qRT-PCR as being expressed in response to osmotic, salt, and cadmium stress. Moreover, almost all JAZ subfamily genes were responsive to jasmonic acid (JA) treatment. In particular, MeJAZ1, MeJAZ13, and MeJAZ14, were highly up-regulated by three treatments, and these genes may deserve further study. This comprehensive study lays the groundwork for future research into TIFY family genes in cassava and may be valuable for genetic improvement of cassava and other related species.

“…Jasmonates are lipid‐derived hormones that play essential roles in plant development and defence against herbivores and necrotrophic pathogens (Howe et al ., 2018; Wasternack & Feussner, 2018). Extensive studies on angiosperms, mainly Arabidopsis thaliana , identified (+)‐7‐ iso ‐JA‐Ile as the ligand of the jasmonate co‐receptor complex formed by the F‐box coronatine insensitive 1 (COI1) and the jasmonate ZIM domain (JAZ) repressors (Xie et al ., 1998; Chini et al ., 2007; Thines et al ., 2007; Katsir et al ., 2008; Fonseca et al ., 2009; Sheard et al ., 2010; Fu et al ., 2021; Saito et al ., 2021). More recently, studies in the bryophyte Marchantia polymorpha and the lycophyte Huperzia selago identified two isomers of dn‐OPDA: dn‐ cis ‐OPDA and dn‐ iso ‐OPDA as the COI1/JAZ ligands in both species, and Δ 4 ‐dn‐ iso ‐OPDA as an additional ligand in M. polymorpha (Monte et al ., 2018, 2022; Kneeshaw et al ., 2022).…”

Evolution of the jasmonate ligands and their biosynthetic pathways

Summary Different plant species employ different jasmonates to activate a conserved signalling pathway in land plants, where (+)‐7‐iso‐JA‐Ile (JA‐Ile) is the ligand for the COI1/JAZ receptor in angiosperms and dn‐cis‐OPDA, dn‐iso‐OPDA and Δ4‐dn‐iso‐OPDA act as ligands in Marchantia polymorpha. In addition, some jasmonates play a COI1‐independent role. To understand the distribution of bioactive jasmonates in the green lineage and how their biosynthetic pathways evolved, we performed phylogenetic analyses and systematic jasmonates profiling in representative species from different lineages. We found that both OPDA and dn‐OPDA are ubiquitous in all tested land plants and present also in charophyte algae, underscoring their importance as ancestral signalling molecules. By contrast, JA‐Ile biosynthesis emerged within lycophytes coincident with the evolutionary appearance of JAR1 function. We identified that the OPR3‐independent JA biosynthesis pathway is ancient and predates the evolutionary appearance of the OPR3‐dependent pathway. Moreover, we identified a negative correlation between dn‐iso‐OPDA and JA‐Ile in land plants, which supports that in bryophytes and lycophytes dn‐iso‐OPDA represents the analogous hormone to JA‐Ile in other vascular plants.

“…3) 32 . Based on this result, we reported the affinity between 1/2 and SlCOI1-SlJAZ pairs using GST-SlCOI1 and fluorescein-labeled SlJAZ degron short peptides (Fl-SlJAZPs) 39 . According to this previous report, SlJAZ12 was excluded in the FA assay because it does not have a conserved JAZ degron sequence 32 .…”

Subtype-selective agonists of plant hormone co-receptor COI1-JAZs identified from the stereoisomers of coronatine

Severe genetic redundancy is particularly clear in gene families encoding plant hormone receptors, each subtype sharing redundant and specific functions. Genetic redundancy of receptor family members represents a major challenge for the functional dissection of each receptor subtype. A paradigmatic example is the perception of the hormone (+)-7-iso-jasmonoyl-L-isoleucine, perceived by several COI1-JAZ complexes; the specific role of each receptor subtype still remains elusive. Subtype-selective agonists of the receptor are valuable tools for analyzing the responses regulated by individual receptor subtypes. We constructed a stereoisomer library consisting of all stereochemical isomers of coronatine (COR), a mimic of the plant hormone (+)-7-iso-jasmonoyl-L-isoleucine, to identify subtype-selective agonists for COI1-JAZ co-receptors in Arabidopsis thaliana and Solanum lycopersicum. An agonist selective for the Arabidopsis COI1-JAZ9 co-receptor efficiently revealed that JAZ9 is not involved in most of the gene downregulation caused by COR, and the degradation of JAZ9-induced defense without inhibiting growth.
