Abstract Background Soil salinity causes huge economic losses to agriculture productivity in arid and semiarid areas worldwide. The affected plants face disturbances osmotic adjustment, nutrient transport, ionic toxicity reduced photosynthesis. Conventional breeding approaches produce little success combating various stresses plants. However, non-conventional approaches, such as vitro tissue culturing, genetic variability the development of salt-tolerant plants, particularly woody trees. Results Embryogenic callus cultures date palm cultivar Khalas were subjected salt levels ranging from 0 300 mM eight subcultures. regenerants obtained salt-treated regenerated evaluated using same concentration NaCl with which calli treated. All salt-adapted (SA) showed improved growth characteristics, physiological performance, ion concentrations K + /Na ratios than non-adapted (SNA) control. Regression between leaf Na net photosynthesis revealed an inverse nonlinear correlation SNA regenerants. Leaf contents stomatal conductance a strong linear relationship SA compared correlation, very poor coefficient determination fidelity selected was also tested 36 random amplified polymorphic DNA (RAPD) primers, 26 produced scorable bands. primers generated 1–10 bands, average 5.4 bands per RAPD primer; there no variation negative Conclusion This is first report variants salt-stressed their potential adaptation cv. Khalas. massive production stress-adapted may be much easier approach. Such can perform better during exposure stress non-treated

Abstract The rapid development and application of molecular marker assays have facilitated genomic selection genome‐wide linkage association studies in wheat breeding. Although PCR‐based markers (e.g. simple sequence repeats functional markers) genotyping by sequencing contributed greatly to gene discovery marker‐assisted selection, the release a more accurate complete bread reference genome has resulted design single‐nucleotide polymorphism (SNP) arrays based on different densities or targets. Here, we evaluated seven types SNP terms their number, distribution, density, associated genes, heterozygosity application. results suggested that Wheat 660K array contained highest percentage (99.05%) genome‐specific SNPs with reliable physical positions. density analysis indicated were almost evenly distributed across whole genome. In addition, 229 266 located 66 834 annotated promoter intervals. genes revealed covered all 35K (97.44%), 55K (99.73%), 90K (86.9%) 820K (85.3%) arrays. Therefore, could act as substitute for other 6 shows promise wide range possible applications. summary, is cost‐effective may be best choice targeted genetic improvement.

As one of the essential cereal crops, wheat provides 20% calories and proteins consumed by humans. Due to population expansion, dietary shift climate change, it is challenging for breeders develop new varieties meeting production requirements. Marker-assisted selection (MAS) has distinct advantages over conventional in plant breeding, such as being time-saving, cost-effective goal-oriented. This review makes attempts give a description different molecular markers: sequence tagged site (STS), simple repeat (SSR), genotyping sequencing (GBS), single nucleotide polymorphism (SNP) arrays, exome capture, Kompetitive Allele Specific PCR (KASP), cleaved amplified polymorphic (CAPS), semi-thermal asymmetric reverse (STARP) target (GBTS). We also summarize some quantitative trait loci (QTL)/genes well their linked markers, which are potentially useful MAS. paper updated information on markers critical traits potential applications breeding programs.

Wheat is a crop of historical significance, as it marks the turning point human civilization 10,000 years ago with its domestication. Due to rapid increase in population, wheat production needs be increased by 50% 2050 and this growth will mainly based on yield increases, there strong competition for scarce productive arable land from other sectors. This increasing demand can further achieved using sustainable approaches including integrated disease pest management, adaption warmer climates, less use water resources frequency abiotic stress tolerances. Out 200 diseases wheat, 50 cause economic losses are widely distributed. Each year, about 20% lost due diseases. Some major rusts, smut, tan spot, spot blotch, fusarium head blight, common root rot, septoria powdery mildew, blast, several viral, nematode, bacterial These badly impact mortality plants. review focuses important present United States, comprehensive information causal organism, damage, symptoms host range, favorable conditions, management strategies. Furthermore, genetic breeding efforts control manage these discussed. A detailed description all QTLs, genes reported cloned provided review. study utmost importance programs throughout world breed resistance under changing environmental conditions.

Abstract High-throughput sequencing (HTS) has instigated a paradigm shift in plant pathology, showcasing its transformative role the management of diseases. As powerful tool, HTS aids identifying pathogens and enhances disease strategies by detecting novel emerging pathogens, tracking outbreaks, contributing to developing disease-resistant cultivars. Despite these benefits, implementation faces obstacles due complexity data interpretation economic factors that affect widespread adoption. This comprehensive review summarizes strengths, limitations, opportunities associated with using managing The article also delves into prospects HTS, incorporating technological advancements, synergy complementary methodologies, capacity-building initiatives, development best practices guidelines. By acknowledging addressing while harnessing full capabilities we advocate for refined approach is critical ensuring global food security, especially context growing population climate change.

Among several important wheat foliar diseases, Stripe rust (YR), Leaf (LR), and Stem (SR) have always been an issue of concern to the farmers breeders. Evolution virulent pathotypes these rusts has posed frequent threats epidemic. Pyramiding rust-resistant genes are most economical environment-friendly approach in postponing this inevitable threat. To achieve durable long term resistance against three rusts, attempt study was made searching for novel sources resistant alleles a panel 483 spring genotypes. This is unique comprehensive where evaluation diverse comprising germplasm from various categories adapted different agro-climatic zones challenged with 18 simultaneous screening field conditions. The genotyped using 35K SNP array evaluated each at two locations consecutive crop seasons. High heritability estimates disease response were observed between environments type. A significant effect population structure visible response. Using compressed mixed linear model approach, 25 genomic regions found associated least rusts. Out these, seven all on chromosome groups 1 6 along 2B. For YR, LR, SR, there 16, 18, 27 QTL (quantitative trait loci) identified respectively, out four environments. Several got annotated viz. NB-LRR, E3-ubiquitin protein ligase, ABC transporter protein, etc. Alien introgressed (on 1B 3D) pleiotropic 7D) captured seedling adult plant responses, respectively. present demonstrates use genome-wide association identification large number favorable leaf, stripe, stem broadening genetic base. Quick conversion into user-friendly markers will accelerate deployment loci breeding programs.
