Special Issue Information

Dear Colleagues,

The journal Plants will be publishing a special issue on the function of lipids in plant stress. Lipids store energy, form cell membranes and surface barriers, and signal and modulate abiotic and biotic plant stress responses. Extensive chemical modifications to lipids, which include hydrolysis, oxidation, glycosylation, acylation, and desaturation, occur in response to both biotic and abiotic stressors. Physical changes to lipids in membranes and related metabolism also occur. Lipids and lipid-derived metabolites interact with proteins to regulate enzyme activity and/or transcription. Any of these changes, and likely some yet to be described, have the potential to mediate and/or modulate plant responses to stress.

The special issue will explore the roles of lipids and lipid properties, both positive and negative, during plant abiotic and biotic stress responses.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Plants is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Long-Chain acyl-CoA Synthetase LACS2 Contributes to Submergence Tolerance by Modulating Cuticle Permeability in Arabidopsis
Plants 2020, 9(2), 262; https://doi.org/10.3390/plants9020262 - 18 Feb 2020
Abstract
In Arabidopsis thaliana, LONG-CHAIN ACYL-COA SYNTHETASEs (LACSs) catalyze the synthesis of long-chain acyl-CoAs and function in diverse biological processes. We have recently revealed that LACS2 is primarily involved in the production of polyunsaturated linolenoyl-CoA, essential for the activation of ethylene response transcription [...] Read more.
In Arabidopsis thaliana, LONG-CHAIN ACYL-COA SYNTHETASEs (LACSs) catalyze the synthesis of long-chain acyl-CoAs and function in diverse biological processes. We have recently revealed that LACS2 is primarily involved in the production of polyunsaturated linolenoyl-CoA, essential for the activation of ethylene response transcription factors-mediated hypoxia signaling. Here, we further reported the dual role of LACS2 in the regulation of submergence tolerance by modulating cuticle permeability in Arabidopsis cells. LACS2-overexpressors (LACS2-OEs) showed improved tolerance to submergence, with higher accumulation of cuticular wax and cutin in their rosettes. In contrast, knockout of LACS2 in the lacs2-3 mutant resulted in hypersensitivity to submergence with reduced wax crystals and thinner cutin layer. By analyses of plant surface permeability, we observed that the hypoxic sensitivities in the LACS2-OEs and lacs2-3 mutant were physiologically correlated with chlorophyll leaching, water loss rates, ionic leakage, and gas exchange. Thus, our findings suggest the role of LACS2 in plant response to submergence by modulating cuticle permeability in plant cells. Full article
