Special Issue Information

Dear Colleagues,

In the past decades, methods for plant breeding have been largely and successfully exploited in developing improved varieties using conventional tools and methodologies. Nowadays, the availability of genomic tools and resources is leading to a new revolution in plant breeding, as they facilitate the study of the genotype and its relationship with the phenotype, not only for Mendelian traits but also for complex traits. Next generation sequencing (NGS) technologies allow the quick and cheap sequencing of genomes and transcriptomes, making available a huge array of genetic information. The analysis of NGS data by means of bioinformatics allows the discovery of new genes and regulatory sequences, and makes available large collections of molecular markers useful for marker-assisted selection (MAS). Genome-wide expression studies provide breeders with an understanding of the molecular basis of complex traits. Genomic approaches such as GWAS and GBS make it possible to screen mutant and germplasm collections for allelic variants in target genes. The re-sequencing of genomes is very useful for the genome-wide discovery of markers amenable for high-throughput genotyping platforms, like SSRs and SNPs, or the construction of high-density genetic maps. All these tools and resources facilitate the study of genetic diversity, which is important for germplasm management, enhancement and use. Also, they allow the identification of markers linked to genes and QTLs by means of conventional genetic mapping or association mapping. These new markers are used for marker-assisted breeding (MAB), including marker-assisted backcross selection, breeding-by-design, or new strategies, like genomic selection (GS). In conclusion, advances in genomics are providing breeders with new tools and methodologies that will allow a great leap forward in plant breeding, including genetic dissection and breeding for complex traits. The present topic is aimed at grouping all studies and contributions that make use of conventional or NGS-based genomic tools for plant breeding.

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. 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 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 550 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.

Pompia is a citrus fruit endemic of Sardinia, Italy, with an essential oil profile showing outstanding anti-inflammatory and anti-microbic properties. Despite its remarkable pharmaceutical potential, little taxonomic and genetic information is available for this species. We applied flow cytometry and classical cytogenetic techniques to assess the DNA content and to reconstruct the karyotype of several Pompia accessions. Molecular data from plastid DNA barcoding and nuclear DNA sequencing were used to study the genetic distance between Pompia and other citrus species. Flow cytometric estimates of DNA content and somatic chromosome counts suggest that Pompia is a regular diploid Citrus species. DNA polymorphisms of nuclear and chloroplast markers allowed us to investigate the genetic relationships between Pompia accessions and other Citrus species. Based on DNA polymorphism data we propose that Pompia is a very recent interspecific hybrid generated by a cross between C. aurantium (as seed bearer) and C. medica (as pollen donor). Our findings pave the way for further and more specific investigations of local Pompia germplasm resources that may help the preservation and valorisation of this valuable citrus fruit tree.
