Special Issue Information

Dear Colleagues,

Plants are often challenged by abiotic stresses such as drought, salinity, high temperature and so on. The exposure of plants to abiotic stresses causes the activation of hormones, signaling cascades, transcription factors, and downstream responses. Mostly, multiple genes are responsible for controlling abiotic stress responses. Recent advances in molecular biology and genomics have begun to provide detailed clues about molecular processes behind these responses. The identification of candidate genes, small RNAs, and metabolic pathways that involved in abiotic stress responses through transcriptomic, epigenomic, and proteomic analysis and/or validation by reverse genetics (CRISPR-Cas9) or overexpression has generated a lot of knowledge in this area.

The scope of this Special Issue is to summarize the knowledge in molecular mechanisms behind these abiotic stresses. Authors are invited to submit original research articles, communication papers, reviews papers, related to but not limited to the following suggested topics:

  • Genes and gene network involved in abiotic stress responses;
  • Transcriptomic or proteomic analysis to find out genes related to abiotic stress;
  • Functional genomics in the abiotic stress response;
  • Genome-wide identification of abiotic-stress-responsive gene families;
  • Co-expression network analysis (WGCNA, clust and so on) to identify gene modules underlying the abiotic stress response;
  • Small RNAs in abiotic stress responses;
  • GWAS to identify genetic factors associated with abiotic stresses;
  • Epigenetic mechanisms (DNA, histone, and RNA methylation) behind abiotic stresses.

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 submissions that pass pre-check are 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. Agriculture is an international peer-reviewed open access semimonthly 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 2600 CHF (Swiss Francs).

As one of the most salt-tolerant grasses, characterizing salt-tolerance genes of Zoysia matrella [L.] Merr. not only broaden the theoretical information of salt tolerance, but also provide new salt-resistant genetic resources for crop breeding. The salt-inducible protein disulfide isomerase (ZmPDI) of Zoysia matrella [L.] Merr. was proved to enhance salt tolerance in homologous overexpression transgenic plants. In order to evaluate its potential application in crops, we conducted the salt tolerance evaluation in heterologous overexpression transgenic rice (OX-ZmPDI), Wild-type (WT) rice, and LOC_Os11g09280 (OsPDI, homologous gene of ZmPDI in rice) knock-out rice generated by CRISPR-Cas9 system (CR-OsPDI). Our findings revealed that OX-ZmPDI rice was higher and exhibited longer main root length, more proline (Pro) and malondialdehyde (MDA), and higher peroxidase (POD) activity than WT control after salt treatment, while CR-OsPDI resulted in contrary phenotypes. These results indicated that ZmPDI can significantly enhance the salt tolerance in rice, whereas loss-of-function of OsPDI reduces the salt tolerance. To further investigate these differences at the molecular level, we collected roots from OX-ZmPDI transgenic, CR-OsPDI transgenic, and wild-type (WT) plants at 0 and 24 h after salt treatment for RNA-seq and data-independent acquisition (DIA) proteome sequencing. Combined analysis of the transcriptome and proteome revealed that ZmPDI has the potential to enhance the salt tolerance of rice by modulating the expression of laccase-6, zingipain-2, WIP3, FKBP65, AKR4C10, GBSSII, Pho1, and TRXf1. Those results provided new information for the molecular regulation mechanism by which ZmPDI improves salt tolerance, and prove the potential of ZmPDI for application in crop breeding. Full article
