Drought has a significant impact on rice yield by restricting the crop's ability to grow and develop. Producing cultivars adapted water deficit conditions is still main interest of breeders geneticists. To address this challenge, set 413 highly diverse populations were evaluated under normal for two growing seasons 2021 2022. High genetic variation was found among genotypes all studied traits. The heritability estimates ranged from 0.82 (panicle length) 0.95 (plant height). Sterility percentage (SET%) most trait affected in seasons. 22 Rice classified as drought tolerant both years. Genome-wide association mapping performed traits using total 700,000 SNPs. GWAS results revealed important major SNPs associated with 26 Significant stable allele effects be study provided that can SNP markers used marker-assisted selection after validation different backgrounds.

Ultraviolet‑B (UV-B) radiation and drought are two environmental stresses that significantly reduce rice quality, yield, growth. Nevertheless, there currently few studies on the association between stress UV‑B stress. This review examined complex interactions stress, with an emphasis cumulative impact these have crop. The looks at how responds to a physiological, biochemical, molecular level, emphasizing shared signaling pathways defense mechanisms. According much literature, simultaneous exposure can synergistic effects intensify damage or cause particular adaptive reactions. Through integration of biotechnological methods advanced breeding techniques, offers strategies for developing cultivars resilient both radiation.

Water deficit affects rice growth, development, and yield. Knowledge of genetic diversity for water tolerance, as well the architecture that is responsible this trait, can accelerate cultivars’ improvement. In study, different tools were applied to assess identify genome regions associated with shoot root traits in germplasm grown under at an early vegetative stage. A panel 177 genotypes was evaluated length (RL), dry weight (RDW), (SL), (SDW). Genetic investigated using means grouping principal component analysis. For genome-wide association a general linear model applied, RL, RDW, SL, SDW phenotypic data converted into Best Linear Unbiased Prediction (BLUPs); genotypic (1185 single nucleotide polymorphism—SNPs-loci); population structure. Overall, little observed, but higher tolerance identified. Several significant SNPs mapped, 81, 5, 53, 41 SDW, respectively. Among identified genes, there are those encoding kinases, proteins involved phytohormone cell wall metabolism, Cytochrome P450. The obtained results provide insight which will be useful improving trait Brazil.

Abstract Sunflower ( Helianthus annuus L.) plays an essential role in meeting the demand for edible oil worldwide. The yield of sunflower seeds encompasses several component traits, including disc diameter. Over three consecutive years, 2019, 2020, and 2022, we assessed phenotypic variation diameter across a diverse set accessions (N = 342) replicated field trials. Upon aggregating data from multiple estimated broad sense heritability H 2 ) trait to be 0.88. A subset N 274 was genotyped by using tunable genotyping‐by‐sequencing (tGBS) method, resulting 226,779 high‐quality SNPs. Using these SNPs phenotype, conducted genome‐wide association study (GWAS) employing two statistical approaches: mixed linear model (MLM) fixed random circulating probability unification (farmCPU). MLM farmCPU GWAS approaches identified 106 8 significant located close 53 21 genes, respectively. analysis peaks: prominent signal on chromosome 10 relatively weaker 16, both which were also detected farmCPU. genetic loci associated with diameter, as well related candidate present promising avenues further functional validation serve basis improvement.

Rice, one of the world's staple crops, faces significant challenges due to abiotic stresses such as drought, salinity and extreme temperatures, which threaten global food security. Traditional breeding methods have limitations in developing stress-tolerant rice varieties within a short time frame. Thus, there is growing interest employing multi-omics approaches, integrating genomics, transcriptomics, proteomics, metabolomics epigenomics, unravel complex molecular mechanisms underlying stress tolerance rice.
