Due to extended periods of below-normal rainfall and rising temperatures, drought is a significant global issue for agricultural productivity. Hydrological, agricultural, meteorological droughts all pose different problems with regard the availability water important crops, which in turn impacts plant development yield. Depending on crop species stage maturity, stress degrades metabolism physiological processes, resulting decreased growth yield losses that can range from 30% 90%. Acclimatization adaptation are two basic techniques plants use survive drought. Rapid alterations processes chemical composition, including modifications osmotic pressure, root leaf size, antioxidant systems, part acclimatization. Xerophytism succulence characteristics drought-resistant have evolved assist preserve cellular integrity balance water-limited environments. Even these tactics, majority crops—such as maize, rice, wheat—remain extremely vulnerable stress. To lessen effects drought, researchers looked into number strategies, both conventional cutting-edge methods. Conventional techniques, like application growth-promoting bacteria (PGPB) morphological modifications, remain essential improving resilience. Recent breakthroughs provided innovative alternatives such nanoparticle (NP) treatments biochar, enhance Biochar enhances soil moisture retention nutrient accessibility, whereas nanoparticles augment absorption bolster molecular resilience under Furthermore, microbial inoculants absorption, facilitating arid conditions. This review examines three staple emphasizing traditional novel approaches consequences We highlight how combining insights ecology, biochemistry, biology, technologies biochar boost production resistance water-scarce

Aegilops tauchii is a D-genome donor of hexaploid wheat and potential source genes for various biotic abiotic stresses including heat drought. In the present study, we used multi-stage evaluation technique to understand effects drought on Ae. tauschii derived introgression lines (ILs). Preliminary (during stage-I) 369 ILs agronomic traits identified 59 agronomically superior ILs. second stage (stage-II), selected ( i.e. , ILs) were evaluated seedling (at 30 °C 35 °C) 20% poly-ethylene glycol; PEG) stress tolerance under growth chambers (stage-II). Heat significantly reduced vigour by 59.29 60.37 percent, respectively. Genotype × treatment interaction analysis index (STI) IL-50, IL-56, IL-68 as high-performing IL-42 IL-44 stress. It also revealed IL-50 stable stresses. Furthermore, in third (stage-III), field condition over two cropping seasons (viz., 2020–21 2021–22), which grain yield 72.79 48.70 Stability was performed identify IL-47, IL-51, IL-259 most stage-III. Tolerant with specific wider adaptability this study can serve resources genetic basis they be utilized developing high-yielding cultivars enhanced tolerance.

Characterization of flag leaf morphology identifies a major genomic region controlling flag leaf angle in the US winter wheat (Triticum aestivum L.)

Theoretical and Applied Genetics, Год журнала: 2024, Номер 137(9)

Abstract Key message Multi-environmental characterization of flag leaf morphology traits in the US winter wheat revealed nine stable genomic regions for different leaf-related including a major region governing angle. Flag is primary contributor to accumulating photosynthetic assimilates. (FLM) determine overall canopy structure and capacity intercept light, thus influencing efficiency. Hence, understanding genetic control these could be useful breeding desirable ideotypes wheat. We used panel 272 accessions from hard (HWW) USA investigate architecture five FLM length (FLL), width (FLW), angle (FLANG), length–width ratio, area using multilocation field experiments. Multi-environment GWAS 14,537 single-nucleotide polymorphisms identified 36 marker-trait associations traits, with being across environments. A novel FLANG ( qFLANG.1A ) was on chromosome 1A accounting 9–13% variation. Analysis spatial distribution set 2354 lines HWW showed higher frequency allele associated narrow KASP assay developed allelic discrimination its independent validation diverse spring accessions. Furthermore, candidate gene analysis two seven putative genes interest each regions. The present study enhances our wheat, particularly FLANG, results will dissecting underlying facilitating development climate-resilient varieties.

Wheat production in the Brazilian Cerrado region faces challenges related to drought and salinity, which limit plant development crop yield. This study evaluated multivariate adaptability of 11 tropical wheat cultivars salinity stresses during early development. plants were grown for 12 days at 25 °C under non-stressful (control) simulated stress conditions with -0.30 MPa iso-osmotic solutions prepared polyethylene glycol or sodium chloride, respectively. The germination, growth rate dry matter accumulation measured. results showed that have distinct morphological responses stressful environmental conditions, having a greater impact on shoot saline root system stability analyses performed using Lin Binns method GGE biplot revealed BIO 190057, BRS 404 TBIO Duque combine all traits simultaneously, being considered tolerant stresses. It was concluded identification adapted adverse is essential advancement sustainable cultivation region, contributing global food security.

GWAS analysis reveals the genetic basis of blast resistance associated with heading date in rice

Frontiers in Plant Science, Год журнала: 2024, Номер 15

Опубликована: Май 21, 2024

Rice blast is a destructive fungal disease affecting rice plants at various growth stages, significantly threatening global yield stability. Development of resistant cultivars stands as practical means control. Generally, association mapping with diversity panel powerfully identifies new alleles controlling trait interest. On the other hand, utilization breeding has its advantage that can be directly applied in program. In this study, we conducted genome-wide study (GWAS) for resistance using 296 commercial low population structure but large phenotypic diversity. We attempt to answer genetic basis behind among early maturing by subdividing based on Heading date 1 ( Hd1 ) functionality. Subpopulation-specific GWAS mixed linear model (MLM) nursery screening three years revealed total 26 significant signals, including nucleotide-binding site leucine-rich repeat (NBS-LRR) genes Os06g0286500 , Os06g0286700 and Os06g0287500 located Piz locus chromosome 6, one Pi-ta Os12g0281300 12. Haplotype analysis associated was exclusively specific Type 14 hd1 japonica rice. Our findings provide valuable insights highlight applicability our elite cultivar detect superior important agronomic traits.
