Special Issue Information

Dear Colleagues,

For many years, the phylogeny and evolution of crop plants have been of great interest to researchers. However, it is only with the development of modern molecular genetic techniques and genomic resources that our understanding of crop evolution has really improved. The evolution of crops combines domestication and subsequent adaptation to new conditions. Further, crop plants are experiencing artificial selection, which can lead to a decrease in the effective population size and an increase in the probability of genetic drift. In this regard, crop evolution can shed light on processes such as domestication, population responses to long-term directional selection, the genetic consequences of recent selective sweeps and restrictions, and can also be a useful model for investigating the molecular basis of adaptive trait evolution. Knowledge of phylogenetic relationships leads to a better understanding of the overall evolutionary processes that generate plant biodiversity. On the other hand, knowledge of how evolutionary forces affect diversity is essential for modern crop breeding and ensuring global food security. Thus, this Special Issue focuses on modern research on the phylogeny and evolution of crop plants, covering a wide range of topics from their origin to the conservation of their genetic resources.

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. Diversity 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.

Abstract
In this article, we analyzed the origin of wild polyploid oats (Avena L., Poaceae) using the region 18S rDNA (partially)–ITS1–5.8S rDNA obtained via NGS. There are six tetraploid (2n = 28) and four hexaploid (2n = 42) wild species differing by specific [...] Read more.
In this article, we analyzed the origin of wild polyploid oats (Avena L., Poaceae) using the region 18S rDNA (partially)–ITS1–5.8S rDNA obtained via NGS. There are six tetraploid (2n = 28) and four hexaploid (2n = 42) wild species differing by specific genome combinations: A. barbata, A. vaviloviana (AB), A. agadiriana (AB or BB), A. magna, A. murphyi, A. insularis (AC or CD), A. ludoviciana, A. sterilis, A. fatua, and A. occidentalis (ACD). We compared the pool of marker sequences of polyploid oats with those of their putative diploid ancestors: A. atlantica (As-genome), A. hirtula (As), A. canariensis (Ac), A. ventricosa (Cv), and A. clauda (paleopolyploid with Cp and A-related rDNA). We found 15 major ribotypes (more than 1000 reads per rDNA pool) in polyploid oats. Comparing them, we found that the AB-tetraploid oats possibly inherited their A-genome ribotypes from A. atlantica (As1-ribotype), whereas their B-genome ribotype is specific and can be a derivative of the A-genome family. Our data do not support the hypothesis of the CD-genome set in A. magna, A. murphyi, and A. insularis: they have an AC-genome ribotype constitution instead. The C-genome-related sequences could have been obtained from A. ventricosa. Hexaploids show a different ribotype pattern than tetraploids; the main ribotypes of A. fatua, A. ludoviciana, and A. sterilis probably belong to the D-group and are also shared with one of the major ribotypes of A. clauda.

Plastids and mitochondria are organelles of plant cells with small genomes, which may exhibit discordant microevolution as we earlier revealed in pea crop wild relatives. We sequenced 22 plastid and mitochondrial genomes of Pisum sativum subsp. elatius and Pisum fulvum using Illumina platform, so that the updated sample comprised 64 accessions. Most wild peas from continental southern Europe and a single specimen from Morocco were found to share the same organellar genome constitution; four others, presumably hybrid constitutions, were revealed in Mediterranean islands and Athos Peninsula. A mitochondrial genome closely related to that of Pisum abyssinicum, from Yemen and Ethiopia, was unexpectedly found in an accession of P. sativum subsp. elatius from Israel, their plastid genomes being unrelated. Phylogenetic reconstructions based on plastid and mitochondrial genomes revealed different sets of wild peas to be most related to cultivated P. sativum subsp. sativum, making its wild progenitor and its origin area enigmatic. An accession of P. fulvum representing ‘fulvum-b’ branch, according to a nuclear marker, appeared in the same branch as other fulvum accessions in organellar trees. The results stress the complicated evolution and structure of genetic diversity of pea crop wild relatives. Full article
