Special Issue Information

Dear Colleagues,

The functional genomics involved in model development link genotype to phenotype. The aim of functional genomics is to understand the expression pattern of genes, gene expression regulation, the interaction of genes and their products, changes in gene expression during the onset of various stress responses, and the functional roles of different genes in cellular processes, and thus to resolve how genes work together to produce a particular phenotype.

The molecular breeding of crops is a technique using DNA markers tightly linked to phenotypic traits to assist in a selection scheme for a particular crop-breeding objective. The molecular breeding of crops is involved in the identification and characterization of suitable genetic markers, and is thus used to improve crops.

The focus of this Special Issue is on functional genomics and the molecular breeding of crops. Examples of topics of interest for this Special Issue include developmental processes, stress responses, functional genomics, comparative genomics, and the molecular breeding of crops. The formats suitable for submission include original research reports, reviews, perspectives/opinions, and methodology articles.

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. 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).

Waxy maize is mainly cultivated in South Korea for the production of food and snacks, and colored maize with increased anthocyanin content is used in the production of functional foods and medicinal products. Association mapping analysis (AMA) is supported as the preferred method for identifying genetic markers associated with complex traits. Our study aimed to identify molecular markers associated with two anthocyanin content and six seed coat color traits in near-isogenic lines (NILs) of colored waxy maize assessed through AMA. We performed AMA for 285 SSR loci and two anthocyanin content and six seed coat color traits in 10 NILs of colored waxy maize. In the analysis of population structure and cluster formation, the two parental lines (HW3, HW9) of “Mibaek 2ho” variety waxy maize and the 10 NILs were clearly divided into two groups, with each group containing one of the two parental inbred lines. In the AMA, 62 SSR markers were associated with two seed anthocyanin content and six seed coat color traits in the 10 NILs. All the anthocyanin content and seed coat color traits were associated with SSR markers, ranging from 2 to 12 SSR markers per characteristic. The 12 SSR markers were together associated with both of the two anthocyanin content (kuromanin and peonidin) traits. Our current results demonstrate the effectiveness of SSR analysis for the examination of genetic diversity, relationships, and population structure and AMA in 10 NILs of colored waxy maize and the two parental lines of the “Mibaek 2ho” variety waxy maize.
