Matching DNA three bases at a time The exchange of genetic information between strands is vital for accurate repair and effective meiotic cell division. Using single-molecule methods molecular dynamics simulations, Lee et al. show that members the family recombinase enzymes responsible these strand reactions search recognize matching time. A single mismatch abolishes triplet recognition, except meiosis-specific recombinase. This enzyme can stabilize partially mismatched triplet, reflecting...
During meiosis, programmed double strand breaks (DSBs) are repaired preferentially between homologs to generate crossovers that promote proper chromosome segregation at Meiosis I. In many organisms, there two exchange proteins, Rad51 and the meiosis-specific Dmc1, required for interhomolog (IH) bias. This bias requires presence, but not activity of Rad51, while Dmc1 is responsible bulk meiotic recombination. How these activities regulated less well established. dmc1Δ mutants, actively...
There are many challenges facing the development of high-yielding, nutritious crops for future environments. One limiting factor is generation time, which prolongs research and plant breeding timelines. Recent advances in speed protocols have dramatically reduced time short-day long-day species by optimizing light temperature conditions during growth. However, winter with a vernalization requirement still require up to 6-10 weeks low-temperature before transition reproductive development....
Multi-environment trials (METs) are essential in plant breeding programs to evaluate crop productivity and adaptability diverse environments. In this study, we demonstrated the practical use of METs grain yield yield-related traits using 276 Korean rice cultivars, divided into three maturity groups (81 early-, 90 medium-, 105 medium–late-maturing cultivars) grown regions (Jeonju, Suwon, Miryang) two planting seasons (early regular planting) for years. Due narrow genetic variability...
Abstract Rice paddies are a major source of methane emissions. To meet the food demand growing population and to cope with global warming, reducing greenhouse gases enhancing yields critical. Here we demonstrate that loss-of-function rice allele, gs3 , mitigates emissions from methanogens by allocating more photosynthates grain less root increases yield enlarging size weight.
The soil-borne pathogen <i>Rhizoctonia solani</i> is one of the most devastating necrotrophic pathogens worldwide, responsible for causing rice sheath blight (RSB). This has a broad host range, affecting economically important monocots and dicots such as rice, wheat, potato, soybean, sugar beet, cucumber. Despite extensive screening germplasm, genes that confer full resistance to RSB have rarely been identified, leading slow progress in breeding resistant varieties. To identify...
Rice is a staple food worldwide, yet its nutritional quality considerably impacted by the milling process, which removes bran layer and other outer parts containing bioactive compounds. This study aimed to optimize degree of semi-waxy rice variety "Milyang 387" (M387) retain key functional components, such as γ-aminobutyric acid (GABA) γ-oryzanol, while preserving desirable cooking qualities. The compared antioxidant capacities, including GABA γ-oryzanol content, physicochemical properties,...
Rad51 is a core component of the eukaryotic homologous recombination machinery and responsible for key mechanistic steps during strand invasion. Higher order oligomers display remarkable degree structural variation, forming rings, compressed filaments, elongated filaments. It unclear whether can transition directly between these different oligomeric structures without disassembling first into monomers. We have used single-molecule microscopy to investigate behavior human assembled on...
Wheat is a major food crop that plays crucial role in the human diet. Various breeding technologies have been developed and refined to meet increasing global wheat demand. Several studies suggested strategies combine generation acceleration systems molecular methods maximize efficiency. However, real-world examples demonstrating effective utilization of these programs are lacking. In this study, we designed demonstrated synergized strategy (SBS) combines rapid efficient techniques, including...
The mammalian non-histone "high mobility group" A (HMGA) proteins are the primary nuclear that bind to minor groove of AT-rich DNA. They may, therefore, influence formation and/or repair DNA lesions occur in DNA, such as cyclobutane pyrimidine dimers (CPDs) induced by UV radiation. Employing both stably transfected lines human MCF7 cells containing tetracycline-regulated HMGA1 transgenes and Hs578T tumor cells, which naturally overexpress proteins, we have shown overexpressing HMGA1a protein...
Saccharomyces cerevisiae RDH54 is a key member of the evolutionarily conserved RAD52 epistasis group genes needed for homologous recombination and DNA double strand break repair. The RDH54-encoded protein possesses translocase activity functions together with Rad51 recombinase in D-loop reaction. By chromatin immunoprecipitation (ChIP), we show that Rdh54 recruited, manner dependent on Rad52, to site-specific induced by HO endonuclease. Because its relatedness Swi2/Snf2 remodelers, have...
Crop breeding should be accelerated to address global warming and climate change. Wheat (Triticum aestivum L.) is a major food crop. Speed (SB) speed vernalization (SV) techniques for spring winter wheat have recently been established. However, there are few practical examples of these strategies being used economically efficiently in programs. We aimed establish evaluate the performance breeder-friendly energy-saving generation acceleration system by modifying SV + SB system.In this study,...
Bakanae disease caused by Fusarium fujikuroi causes crop failure and yield losses in the majority of rice-growing countries. In this study, we employed a joint strategy quantitative trait locus (QTL) mapping–Genome-Wide Association Study (GWAS) to investigate novel genetic loci associated with resistance using population 143 BC1F8 RILs derived from cross between Ilpum × Tung Tin Wan Hien1. The phenotypic data bioassay genotypic generated DNA chip were utilized perform QTL mapping GWAS study....
The cost structure of the CGAM system, a predefined cogeneration system suggested to unify different methodologies thermoeconomic analysis, was investigated by using method called modified productive analysis (MOPSA). An emphasis has been specially put on how is affected chosen level aggregation that specifies subsystems. It found unit products dependent only when one considers entropy flow as parameters determine products. Copyright © 2004 John Wiley & Sons, Ltd.
