Summary: This study aimed to predict heterosis in rice breeding programs by using genetic distance. The results showed a positive correlation between marker-based genetic distance and mid-parent heterosis, as well as between genetic distance and better-parent heterosis. Therefore, microsatellite marker-defined distances can be used to predict high grain yield and low sterility in rice hybrids.

Summary: Plant hybridization is essential for breeding new varieties with desired traits. This study aimed to evaluate gene action, heritability, and heterosis of various traits in rice under water deficit conditions. Crossing four different water-deficit tolerant rice genotypes produced populations with improved performances and adaptability to water deficit condition. The study also identified different types of gene interactions influencing the inheritance of specific traits. The findings provide valuable insights for future phenotypic and genotypic association studies in rice and for developing water deficit tolerant rice cultivars.

Summary: This article investigates the differences between two major subspecies of Asian cultivated rice, japonica/geng and indica/xian. It reviews their origin, domestication, physiological and phenotypical differences, as well as molecular mechanism variations. Additionally, an ideal plant architecture for geng rice varieties in northern regions is proposed.

Summary: In this study, a population of chromosome segment substitution lines (CSSLs) derived from a cross between two different types of rice was used to analyze multiple traits of brown rice. The results showed significant correlations among most of the brown rice traits and identified 61 QTLs for these traits under three environments. Additionally, 30 pairs of gene interactions were determined for specific brown rice traits, providing further understanding of the genetic basis of brown rice traits and facilitating genetic improvement of rice yield and quality through breeding.

Summary: The successful breeding and cultivation of perennial rice provides an opportunity for sustainable development, increasing crop productivity, farmer livelihoods, and soil health while reducing resource use. Planting perennial rice not only improves crop yields but also accumulates organic carbon and nitrogen in the soil, thus improving soil quality. Farmers prefer cultivating perennial rice as it saves labor and input costs.

Summary: By conducting single-locus and multi-locus genome-wide association studies on a panel of 529 rice core varieties, a total of 152, 106, 12, 111, and 64 SNPs associated with various yield-related traits were detected. Furthermore, 74 significant quantitative trait nucleotides were identified across different multi-locus GWAS methods, and 20 common QTNs were discovered by both single-locus and multi-locus methods. Two candidate key genes (LOC_Os09g02830 and LOC_Os07g31450) were found to affect grain width and thousand-grain weight, respectively.

Summary: High temperatures can impair photosynthesis and reduce rice productivity, but heat-tolerant wild rice is able to maintain leaf growth and biomass at 45 degrees C with increased soluble sugar concentrations. Differential abundance of carboxylation and heat-sensitive proteins may contribute to the higher thermal tolerance of wild rice compared to cultivated rice.

Summary: In this study, rice germplasm from Pakistan and the United States was used to identify key genes related to yield through a genome-wide association study. The results showed the genetic diversity in the germplasm and provided new genes for yield improvement. The study also discovered pleiotropic loci, candidate genes, and novel markers associated with yield, which can be used for marker-assisted selection and QTL pyramiding to improve rice breeding programs.

Summary: The study on intraspecific hybrid sterility in Asian cultivated rice reveals the origin, differentiation, and genetic aspects among subgroups. The identification of conserved and specific loci responsible for hybrid sterility between subgroups contributes to the divergence of Asian cultivated rice. Future research aims to characterize the genes for hybrid sterility and segregation distortion to unlock the mysterious relationship between hybrid sterility and Asian cultivated rice divergence.

Summary: Rice is a staple food for most of the world's population, but drought negatively affects its yield. This study identified stable QTLs for drought tolerance in rice and conducted a meta-QTL analysis for use in breeding programs. The identified genes can be used in molecular breeding and genetic engineering for drought resistance in rice.

Summary: This study evaluated the performance of different genomic prediction models for two traits across three different crops. The results showed that the Bayes B model with a subset of significant markers and selecting the training population based on narrow sense heritability improved prediction accuracy. The study also found that traits with higher heritabilities were associated with higher prediction accuracy.

Summary: The commercial japonica/GJ variety DHX2 displayed hybrid sterility when crossing with other GJ varieties, which was improved by knocking out extra copies of the Sc gene in DHX2. The genome of DHX2 may have undergone slight introgression from Basmati1, and both DHX2 and Basmati1 harbored three copies of Sc. Additionally, the introduction of GS3 and BADH2/fgr genes from Basmati1 conferred the slender and fragrance grain characteristics of DHX2, providing a novel strategy for hybrid breeding.

Summary: This study demonstrates the significance of Bacillus subtilis synthesized Fe3O4 NPs in alleviating arsenic toxicity in rice plants. The Fe3O4 NPs reduce arsenic accumulation, act as a nano adsorbent, and restrict arsenic uptake, thus reducing stress-related parameters and enhancing the growth of rice seedlings.
