Special Issue Information
Dear Colleagues,
Reproduction in plants is crucial not only for shaping genetic diversity within and maintaining genetic diversity between species, by promoting, limiting, or avoiding the exchange of genes and chromosomes between different genomes, but also for modeling the genetic structure of populations, hence contributing to the composition of individual genotypes within species and the organization of their genomes. Consequently, strategies for preserving plant germplasm resources, as well as methods and schemes for improving crop plant populations and breeding new varieties, depend on plant reproductive systems. Furthermore, comprehending the genetic and molecular bases of plant reproductive systems can also help to overcome the reproductive barriers that limit crop yield and quality in crop species and, in general, to understand the evolutionary dynamics, genetic structure, and diversity partitioning models of plant populations.
With the strengthening of genomics and biotechnologies, the scientific community is now aware that mapping and cloning, as well as editing or silencing, the genes that control meiosis, gametogenesis, pollen–pistil interaction, fertilization and fertilization-independent seed and seedless fruit production are promptly achievable. In addition, studying and unveiling the mechanisms that regulate plant reproductive systems in crop species and their wild relatives, including progenitors, are crucial as the overall production of cultivated populations (i.e., varieties) typically depend on genetic factors and networks controlling the fundamental steps of seed and fruit developmental pathways.
I am confident that the control of plant reproduction systems and sexual barriers (e.g., male sterility and self-incompatibility, apomixis, etc.) can potentially change the distribution and scale of actions for preserving and exploiting biodiversity, and investments for breeding new varieties disrupt the existing commercial supply chains and lead to greater use efficiency of agronomic inputs, thereby contributing to the amelioration of environmental quality traits and mitigation of climate change risks. Within this context, genomics along with biotechnologies will play a central role in the advancement of knowledge in plant genetics and breeding, as their main applicative tools and platforms are suitable for studying reproductive systems and their effects on population genetics, including the transmission and expression of quali-quantitative traits.
This SI of Plants is dedicated to all these compelling and inspiring topics. The main aim is to outline recent advances and novel findings in the genetics and genomics of plant reproductive systems in both cultivated species and wild ancestors, and to provide a better understanding of their potential applications in crop plant improvement.

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. Plants 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 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.
