Special Issue Information

Dear Colleagues,

Plant growth is restricted by abiotic and biotic stresses, such as drought, high temperatures, cold, pathogenic bacteria and other adverse factors. Additionally, plants have evolved a wide array of resistant mechanisms. With the explosive development of OMICS technologies, e.g., genomics, transcriptomics, proteomics, and metabolomics, crop improvement is entering on a new era of biological information. In addition, it is important to investigate gene function and regulatory mechanisms via gene editing, overexpression, yeast two-hybrid methods and other molecular means for the purpose of future plant breeding. The combination of omics and molecular methods can help to accelerate the breeding process for stress resistance. Thus, we are launching this Special Issue of Agronomy, entitled “Analysis of Plant Resistance Mechanism for Crop Breeding”.

We aim to collect remarkable studies into:

  • Integration using multi-omics to reveal the complex genetic regulatory networks and hub genes controlling the mechanisms of stress tolerance;
  • Genetic regulatory network and model analysis of abiotic and biotic stress responses;
  • New functional genes or genetic loci identification for stresses tolerance.

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. Agronomy 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 2600 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.

Bacterial wilt, caused by the Ralstonia solanacearum species complex, is one of the most damaging bacterial diseases in tobacco and other Solanaceae crops. In this study, we conducted an analysis and comparison of transcriptome landscape changes in seedling roots of three tobacco BC4F5 lines, C244, C010, and C035, with different resistance to bacterial wilt at 3, 9, 24, and 48 h after R. solanacearum infection. A number of biological processes were highlighted for their differential enrichment between C244, C010, and C035, especially those associated with cell wall development, protein quality control, and stress response. Hence, we performed a genome-wide identification of seven cell wall development-related gene families and six heat shock protein (Hsp) families and proposed that genes induced by R. solanacearum and showing distinct expression patterns in C244, C010, and C035 could serve as a potential gene resource for enhancing bacterial wilt resistance. Additionally, a comparative transcriptome analysis of R. solanacearum-inoculated root samples from C244 and C035, as well as C010 and C035, resulted in the identification of a further 33 candidate genes, of which Nitab4.5_0007488g0040, a member of the pathogenesis-related protein 1 (PR-1) family, was found to positively regulate bacterial wilt resistance, supported by real-time quantitative PCR (qRT-PCR) and virus-induced gene silencing (VIGS) assays. Our results contribute to a better understanding of molecular mechanisms underlying bacterial wilt resistance and provide novel alternative genes for resistance improvement. Full article
