“…In response to the invasion of necrotic pathogens, jasmonic acid is (+)-7-isojasmone-1-isoleucine (JA-Ile), which can be sensed through the COI1-JAZ co-receptor system in the disease-resistant response [36]. Although we did not observe that JA-Ile was inhibited at 24hpi, it was significantly inhibited at 36hpi and 48hpi.…”

The potato early blight was caused by Alternaria solani (Aso). At present, potato early blight resistant varieties are lacking. The experiment of Aso inoculation on a.k.a. Favorita showed that the content of chlorophyll decreased continuously within 2 days after inoculation. In addition, the contents of JA-Ile, SA, ABA and IAA were determined by LC-MS.The results of two defense-related hormones showed that jasmonic acid content decreased significantly, while jasmonic acid content did not change significantly. In order to understand the difference in gene expression of potatoes infected by Aso, the 24 hpi, 36 hpi and 48 hpi transcriptome were determined. The results showed that the gene annotation and cluster analysis of DEGs revealed a variety of defense responses to Aso infection, especially the plant hormone signal transduction pathway. The differential expression of 10 DEGs was confirmed by qPCR analysis. Finally, through weighted gene co-expression network analysis (WGCNA), "samonl" was determined as a key hormone-related network in the process of Aso infection in potatoes. This study provides an important clue for understanding the interaction between potato and Aso and for disease resistance breeding.

“…The perception mechanism of the JA-signaling pathway is well known in Arabidopsis, which is activated through the formation of the COI1-JAZ complex mediated by the JA-Ile ligand 11,12,30 . COI1 co-receptor acts like a primary receptor recognizing the ligand JA-Ile and then binding to JAZ repressors 11,12 , which are degraded by 26S proteasome 9,10 .…”

“…Besides Arabidopsis and the bryophyte Marchantia polymorpha 29 , understanding of the molecular mechanisms involved in JA-Ile perception and the activation of the JA-signaling pathway in other plant species is very limited 30 . Previously, we have described the high conservation of COI1 and JAZ proteins in F. vesca suggesting a critical role for the JA-signaling pathway in this species 20,28 . This study aimed was to evaluate if the new degron IPMQRK found in F. vesca JAZ1 is conserved in F. × ananassa and the Rosaceae family and if it can interact with the corresponding COI1 protein in the presence of COR.…”

The phytohormone jasmonoyl-isoleucine (JA-Ile) regulates fundamental plant processes as developmental and defense responses. JA-Ile mediates the interaction between the F-box protein COI1 (part of the SCF COI1 E3 ubiquitin ligase) and a JAZ repressor leading to early jasmonate responses. The Arabidopsis JAZ1 protein contains the canonical LPIARR degron sequence, which is responsible for the stabilization of the AtCOI1-JA-Ile-AtJAZ1 complex. In strawberry (Fragaria × ananassa) JAZ family was described at the transcriptional level during fruit development but the information about the interaction mode of this complex is still scarce at the molecular level. To gain insight into the strawberry JA-Ile receptor complex, we evaluated the interaction at the structural level, and protein models were built and analyzed for FaCOI1 and FaJAZ1, FaJAZ8.1, and FaJAZ10. The interaction between FaCOI1 and FaJAZ1, FaJAZ8.1 and FaJAZ10 were explored using several ligands, through molecular docking and molecular dynamics (MD) simulations, finding the strongest interaction with (+)-7-iso-JA-Ile than other ligands. Additionally, we tested interactions between FaCOI1 and FaJAZs by yeast two-hybrid assays in the presence of coronatine (COR, a JA-Ile mimic). We detected strong COR-dependent interactions between FaCOI1 and FaJAZ1. Interestingly, FaJAZ1 contains a new non-canonical (IPMQRK) functional degron sequence, in which Arg and Lys are the key residues for maintaining the interaction of the FaCOI1-COR-FaJAZ1 complex as we observed in mutated versions of the FaJAZ1 degron. Phylogenetic analysis showed that the IPMQRK degron is only present in orthologs belonging to the Rosoideae but not in other Rosaceae subfamilies. Together, this study uncovers a new degron sequence in plants, which could be required to make an alternative and functional JA-Ile perception complex in strawberry. Jasmonates (JAs) are phytohormones that regulate development and stress processes in land plants 1-3. The (+)-7-iso-jasmonoyl-l-isoleucine (JA-Ile) is the bioactive jasmonate in Arabidopsis 4 and accumulates at the early stages of development in grape and strawberry fruits 5,6. The bacterial phytotoxin coronatine (COR) is structurally and functionally analogous to JA-Ile 7 .

“…(+)-Jasmonoyl- l -isoleucine (JA-Ile, 1 ) is a lipid-derived plant phytohormone, implicated in the regulation of plant growth, fertility, and defense against pathogens and insects 1 – 3 . JA-Ile-mediated signal transduction depends on the COI1-JAZ co-receptor system, composed of an F-box protein CORONATINE INSENSITIVE 1 (COI1) and JASMONATE ZIM-DOMAIN (JAZ) repressor protein 4 – 6 .…”

In recent years, the biology of the evolutionary origin of phytohormone signaling has made significant progress. Among them, the ligand-receptor co-evolution found in jasmonate signaling has attracted the attention of plant scientists. Dinor-cis-12-oxo-phytodienoic acid (dn-cis-OPDA, 4) and dn-iso-OPDA (5) are ancestral plant hormones of the bryophyte Marchantia polymorpha L. We succeeded in the first practical synthetic supply of these hormones as well as their possible catabolites. These compounds are expected to be useful in the study of ancestral jasmonate signaling in bryophytes.
