Plant biodiversity is central to the implementation of sustainable production systems, ensuring global food security, and increasing crop resistance and resiliance to climate change and invasive and native biotic stresses. Plant genetic resources (PGR) have been collected and exchanged for centuries, but the rapid development of novel tools for genetic analysis is changing the way we can uncover diversity and exploit its value in agriculture. The integration of novel analytical tools is currently crucial for translating research into a much-needed, more efficient management and use of PGR.
The forthcoming Special Issue aims to provide an overview of recent topics on plant genetics and biotechnology in biodiversity, with enphasis on agricultural genetic diversity. Papers will present current trends on genetic resources description, conservation, management and research, and will highlight how new approaches and methodogies can boost both our understanding and exploitation of PGR.
This Special Issue is launched to honor the memory of Prof. Gian Tommaso Scarascia Mugnozza, and in recognition of his many contributions to plant breeding and 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 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.

Tentative title: The concept of centers of origin and domestication in Phaseolus, a case of multiple domestications
Tentative authors: Andrea Ariani, Jorge Berny Mier y Teran, Paul Gepts
Tentative abstract: The genus Phaseolus constitutes an interesting case study into the process of domestication. In this review, we will describe the geographic and, wherever possible, the ecological extent of the distributions of the wild progenitors of the five domesticated species of the genus, with particular emphasis on common bean (P. vulgaris). Such analysis was made possible through the successive collections during many decades by several noteworthy explorers, giving us an overall picture of the adaptation of these wild relatives. There is a positive correlation between the economic importance of the five domesticates and the distribution of their respective wild ancestor. Two species – common bean and lima bean (P. lunatus) – have extraordinarily large distributions, of some 10,000 km long. Genomic analysis suggest that these distributions arose through multiple, possibly bird-mediated dispersal events from hitherto unknown ancestors. Furthermore, these different events led to different climatic adaptations. In these different areas, gene flow between wild ancestors and domesticated descendants has predominated in the direction from domesticated to wild, while maintaining the contrasting phenotypes of wild vs. domesticated types. We end by discussing further necessities in the exploration of wild ancestors and species in the genus Phaseolus.

Title: The functional impact of transposable elements on the diversity of plant genomes

Abstract: Transposable elements (TEs) are self-mobilized DNA sequences that constitute a large portion of plant genomes. Being selfish DNA, they utilize different mobilization mechanisms to persist and proliferate in host genomes. It is important that new TE insertions generate de novo variability, most of which is likely to be deleterious, but some can be advantageous. Also, a growing body of evidence shows that TEs were continually recruited by their hosts to provide additional functionality – a process called molecular domestication. Here, we review potential ways in which transposable elements can provide novel functions to host genomes, from simple gene knock-outs to complex rewiring of gene expression networks. We discuss possible implications of TE presence and activity in crop genomes to agricultural production.

Tentative title: Exploitation Of Rice Landraces - A Feasible Option For Crop Improvement?

Abstract: Crop domestication is a complex process mediated by a series of fruitful phenotypic changes to modify a wild species suitable for cultivation, harvest as well as consumption. Rice Landraces are good source of genetic variability which can be used to complement and broaden the gene pool of advanced genotypes. They played a very important role in the local food security and sustainable development of agriculture. Genome wide association study (GWAS) examines the associations between markers and trait. GWAS makes it possible to simultaneously screen a very large number of accessions for variation underlying complex traits. Study of selection sweep in landraces can able to find the nature of selection by farmers and possible fixation of alleles. Whole genome sequencing using next-generation sequencing (NGS) technologies could identify millions of variants in a rapid, efficient and cost effective manner. The results from these studies will help in understanding the genetic diversity among rice landraces and will be shared with plant breeders in order to incorporate in their breeding program.
