Special Issue Information

Dear Colleagues,

Rice is one of the most important cereal crops and the staple food of over half of the world’s population, especially in Asian countries. Due to its small genome and simple genetic transformation, rice is considered an ideal model crop. In recent years, technologies such as map-based cloning, high-throughput sequencing, whole-genome association analysis, and gene editing have allowed for the cloning of genes for important agronomic traits in rice and the exploration of a variety of allele variations, providing important references for genetic improvement and breeding. In addition, germplasm resources are the chip of crop breeding, and no breakthrough in crop breeding could have been achieved without the innovation of important germplasm.

In order to promote academic exchange on the latest trends and achievements in rice molecular breeding and germplasm improvement, this Special Issue will focus on rice genetic improvement and breeding, promote collaborative exploration of the latest research trends and directions, and seek opportunities for cooperation in this field. We welcome all original research papers and comments for submission to this Special Issue.

The contributions of this Special Issue may include, but are not limited to, the exploration of new genes for rice molecular breeding and germplasm innovation. Particularly popular topics include the cloning and functional research of rice genes, such as gene cloning, gene editing, whole-genome association analysis, and the identification of significant alleles, as well as the innovative progress of high-yield, high-quality, multi-resistant, safe, and efficient new rice germplasm.

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. 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).

Improving the efficiency of germplasm innovation has always been the aim of rice breeders. Traditional hybrid breeding methods for variety selection rarely meet the practical needs of rice production. The emergence of genome-editing technologies, such as CRISPR/Cas9, provides a new approach to the genetic improvement of crops such as rice. The number of published scientific papers related to “gene editing” and “CRISPR/Cas9” retrievable on websites both from China and other countries exhibited an increasing trend, year by year, from 2014 to 2023. Research related to gene editing in rice accounts for 33.4% and 12.3% of all the literature on gene editing published in China and other countries, respectively, much higher than that on maize and wheat. This article reviews recent research on CRISPR/Cas9 gene-editing technology in rice, especially germplasm innovation and genetic improvement of commercially promoted varieties with improved traits such as disease, insect, and herbicide resistance, salt tolerance, quality, nutrition, and safety. The aim is to provide a reference for the precise and efficient development of new rice cultivars that meet market demand. Full article
