Special Issue Information

Dear Colleagues,

Over the past two decades, ecological and evolutionary research has been booming because of the integration of different disciplines, such as geography, computer science and big data science. Macro-ecology and macro-evolution are sprouting because of these interdisciplinary studies. However, they can become even more prosperous in the light of conservation, as human society and nature are now in an unprecedented era with extraordinary changes. Toward this end, in this Special Issue, we welcome the submission of papers that address the relevant conservation issues from the macro-ecological and macro-evolutionary perspectives. Interested authors are not necessarily required to submit their papers with sufficiently large spatial scales or long-term experimental periods. The submitted manuscripts should fit our Special Issue as long as the ideas and results convey take-home messages regarding the conservation, resilience or mitigation of biodiversity under global change and human influence.

Prof. Dr. Youhua Chen
Guest Editor

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. Biology 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 2700 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Abstract
Naturally transgenic plants are plants that have undergone Agrobacterium-mediated transformation under natural conditions without human involvement. Among Arachis hypogaea L., A. duranensis Krapov. & W.C. Greg, A. ipaensis Krapov. & W.C. Greg, A. monticola Krapov. & Rigoni, and A. stenosperma Krapov. [...] Read more.
Naturally transgenic plants are plants that have undergone Agrobacterium-mediated transformation under natural conditions without human involvement. Among Arachis hypogaea L., A. duranensis Krapov. & W.C. Greg, A. ipaensis Krapov. & W.C. Greg, A. monticola Krapov. & Rigoni, and A. stenosperma Krapov. & W.C. Greg are known to contain sequences derived from the T-DNA of “Agrobacterium”. In the present study, using molecular genetics and bioinformatic methods, we characterized natural transgenes in 18 new species from six sections of the genus Arachis. We found that small fragments of genes for enzymes of the agropine synthesis pathway were preserved only in some of the studied samples and were lost in the majority of the species during evolution. At the same time, genes, similar to cucumopine synthases (cus-like), remained intact in almost all of the investigated species. In cultivated peanuts, they are expressed in a tissue-specific manner. We demonstrated the intraspecific variability of the structure and expression of the cus-like gene in cultivated peanuts. The described diversity of gene sequences horizontally transferred from Agrobacterium to plants helps to shed light on the phylogeny of species of the genus Arachis and track possible hybridization events. Data on the ability of certain species to hybridize are useful for planning breeding schemes aimed at transferring valuable traits from wild species into cultivated peanuts. Full article
