Quality Gene Mining and Breeding of Wheat

Dear Colleagues,

Wheat holds significant global importance as a staple food crop due to its widespread cultivation and economic significance. Therefore, losses in the yield and quality of wheat will severely affect our subsistence and life. Many traits relating to wheat production, such as disease resistance and its high quality, are mainly controlled by quality trait genes. Common wheat is a hexaploidy crop (2n = 6x = 42, AABBDD) with many wheat varieties, landraces and wild relatives. These germplasm carry plentiful excellent-quality genes for the genetic enhancement of wheat. Recent advances in wheat genomic sequencing and molecular genetics technologies have enabled us to mine and clone these quality genes for molecular breeding more efficiently. With the emergence of various powerful phenotype and genotype techniques, our ability to mine and clone quality trait genes has substantially increased. However, the precise mapping and accurate isolation of new genes from both wheat and its wild relatives remain relatively difficult. This Special Issue aims to present the latest developments in and applications of wheat phenotyping, genome sequencing, gene mapping, map-based cloning and molecular breeding techniques in the mining of quality genes in common wheat and its wild relatives.

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 250 words) can be sent to the Editorial Office for assessment.

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. Genes 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.
