“…These are created, maintained and modulated by cell to cell transport of auxin (as reviewed in Adamowski and Friml 2015), a plant-specific process so far not verified for other plant hormones. [Beside auxin, transporters involved in long-distance transfer of ABA, strigolactones, cytokinins and, eventually, also jasmonic acid conjugates , Kretzschmar et al 2012, Borghi et al 2015, Zurcher et al 2016, Li et al 2017) have been characterized. However, currently it is still unclear if these indeed function in polar transport of the respective hormones and not simply in phloem/xylem (un)loading, which needs to be demonstrated.]…”

Different subclasses of ATP-binding cassette (ABC) transporters have been implicated in the transport of native variants of the phytohormone auxin. Here, the putative, individual roles of key members belonging to the ABCB, ABCD and ABCG families, respectively, are highlighted and the knowledge of their assumed expression and transport routes is reviewed and compared with their mutant phenotypes. Protein-protein interactions between ABC transporters and regulatory components during auxin transport are summarized and their importance is critically discussed. There is a focus on the functional interaction between members of the ABCB family and the FKBP42, TWISTED DWARF1, acting as a chaperone during plasma membrane trafficking of ABCBs. Further, the mode and relevance of functional ABCB-PIN interactions is diagnostically re-evaluated. A new nomenclature describing precisely the most likely ABCB-PIN interaction scenarios is suggested. Finally, available tools for the detection and prediction of ABC transporter interactomes are summarized and the potential of future ABC transporter interactome maps is highlighted.

“…It is widely accepted that one of the most important phyto‐hormone mediating the plant cell response to (a)biotic stresses is represented by jasmonoyl‐isoleucine (JA‐Ile), the primarily active form of jasmonic acid, able to translocate through membranes and to move through xylem from roots to leaves and backward in the model species Arabidopsis thaliana (Koo and Howe , Chini et al , Poudel et al , Li et al ). Recently, an independent role as signalling molecule has also been proposed for OPDA‐Ile‐like related compounds (Arnold et al , Wasternack and Hause ).…”

Multiple stresses are becoming common challenges in modern agriculture due to environmental changes. A large set of phytochemicals collectively known as oxylipins play a key role in responses to several stresses. Understanding the fine-tuned plant responses to multiple and simultaneous stresses could open new perspectives for developing more tolerant varieties. We carried out the molecular and biochemical profiling of genes, proteins and active compounds involved in oxylipin metabolism in response to single/combined salt and wounding stresses on Medicago truncatula. Two new members belonging to the CYP74 gene family were identified. Gene expression profiling of each of the six CYP74 members indicated a tissue- and time-specific expression pattern for each member in response to single/combined salt and wounding stresses. Notably, hormonal profiling pointed to an attenuated systemic response upon combined salt and leaf wounding stresses. Combined, these results confirm the important role of jasmonates in legume adaptation to abiotic stresses and point to the existence of a complex molecular cross-talk among signals generated by multiple stresses.

“…endogenous JA and JA--Ile were found to be mobile in tomato and wild tobacco [26,27]. The identification of NPF2.10/GTR1 as JA and JA--Ile transporter [43,44] and of AtABCG16/JAT1 mediating nuclear JA--Ile influx [45], further underline the importance of a regulated distribution of jasmonate species across cells and organs. Due to unidentified multiple enzymes [15] and gene redundancy (Supplemental Figure 1), were low in both scions and rootstocks of wt/aos grafted plants and increased significantly in both organs upon scion wounding (Fig.…”

Multicellular organisms rely upon the movement of signaling molecules across cells, tissues and organs to communicate among distal sites. In plants, herbivorous insects, necrotrophic pathogens and mechanical wounding stimulate the activation of the jasmonate (JA) pathway, which in turn triggers the transcriptional changes necessary to protect plants against those challenges, often at the expense of growth. Although previous evidence indicated that JA species can translocate from damaged into distal sites, the identity of the mobile compound(s), the tissues through which they translocate and the consequences of their relocation remain unknown. Here, we demonstrated that endogenous JA species generated after shoot injury translocate to unharmed roots via the phloem vascular tissue in Arabidopsis thaliana. By wounding wild--type shoots of chimeric plants and by quantifying the relocating compounds from their JA--deficient roots, we uncovered that the JA--Ile precursor 12--oxo-phytodienoic acid (OPDA) is a mobile JA species. Our data also showed that OPDA is a primary mobile compound relocating to roots where, upon conversion to the bioactive hormone, it induces JA--mediated gene expression and root growth inhibition. Collectively, our findings reveal the existence of long--distance transport of endogenous OPDA which serves as a communication molecule to coordinate shoot--to--root responses, and highlight the importance of a controlled distribution of JA species among organs during plant stress acclimation. c 1x 3x sw
