Special Issue Information

Dear Colleagues,

Rice is the staple food of more than half of the world’s population and improving rice production is a major challenge due to the global population explosion and climate change. Traditional breeding has played a major role in improving rice yields, but it is time-consuming and laborious. With the rapid development of molecular biology in recent decades, molecular breeding using molecular marker-assisted selection, genome-wide selection, and other techniques has shown great advantages in improving the agronomic traits of rice. Additionally, genome editing technology can accurately modify the DNA sequences of multiple genes simultaneously and in a short period of time, which represents great application prospects for improving multiple traits in a variety of species, including rice. Therefore, the combined use of molecular breeding and traditional breeding will come to be a better means of improving the agronomic traits of rice.

This Special Issue focuses on recent advances in the role molecular breeding plays in improving the agronomic traits of rice. Submitted papers could cover the development of high-throughput molecular marker-assisted selection modules for several key known genes that are important for agronomic traits, the mining of breeding-favorable alleles of known genes or unknown genes, and the validation of their functions. All original research, opinions, and reviews are welcome.

Rice (Oryza sativa L.) serves as a staple food for over half the global population, but its cultivation faces significant challenges from abiotic stresses such as drought, salinity, temperature extremes, and heavy metal toxicity. These stresses adversely impact rice growth, yield, and quality, posing a threat to global food security. This review comprehensively explores the physiological, biochemical, and molecular responses of rice to abiotic stresses, highlighting key functional genes and signaling pathways. Advanced breeding strategies, including molecular marker-assisted selection (MAS), genome-wide association studies (GWASs), and CRISPR/Cas9-based genome editing, offer innovative solutions for enhancing stress tolerance. Integrated approaches combining traditional breeding, modern molecular techniques, and exogenous applications such as plant hormones and beneficial microorganisms are discussed. These methods aim to develop rice varieties resilient to multiple stresses, ensuring sustainable production. Future prospects emphasize the integration of multi-omics technologies and the establishment of stress-resistant germplasm banks to accelerate breeding programs. This review provides some support for the development of stress-tolerant rice varieties to help address agricultural challenges in the context of climate change. Full article

Global warming affects crop growth and development, threatening food security. As one of the essential food crops, rice is severely affected by high temperature stress, which compromises both its yield and quality. Therefore, gaining a deep understanding of the molecular mechanisms by which rice responds to heat stress and breeding rice varieties that are tolerant to such stress is crucial for maintaining food security. This review summarizes the impacts of heat stress on yield and quality-related traits at different growth and development stages of rice, the molecular mechanisms of rice perception and response to heat stress, and the improvement in and breeding of heat-tolerant rice varieties using existing superior alleles/QTLs. We also discuss the opportunities and challenges in creating highly heat-tolerant rice germplasm, providing new ideas and insights for the future breeding of heat-tolerant rice varieties.
