Improper use of water resources in irrigation that contain a significant amount salts, faulty agronomic practices such as improper fertilization, climate change etc. are gradually increasing soil salinity arable lands across the globe. It is one major abiotic factors inhibits overall plant growth through ionic imbalance, osmotic stress, oxidative and reduced nutrient uptake. Plants have evolved with several adaptation strategies at morphological molecular levels to withstand stress. Among various approaches, harnessing crop genetic variability different genepools developing tolerant plants offer most sustainable way salt stress mitigation. Some important determinants controlling tolerance been uncovered using classical approaches. However, its complex inheritance pattern makes breeding for challenging. Subsequently, advances sequence based approaches functional genomics greatly assisted underpinning novel variants whole genome level. This current review aims shed light on physiological, biochemical, responses under defense mechanisms plants, underlying genetics bi-parental QTL mapping Genome Wide Association Studies, implication Genomic Selection breed lines.

The present day's ongoing global warming and climate change adversely affect plants through imposing environmental (abiotic) stresses disease pressure. major abiotic factors such as drought, heat, cold, salinity, etc., hamper a plant's innate growth development, resulting in reduced yield quality, with the possibility of undesired traits. In 21st century, advent high-throughput sequencing tools, state-of-the-art biotechnological techniques bioinformatic analyzing pipelines led to easy characterization plant traits for stress response tolerance mechanisms by applying 'omics' toolbox. Panomics pipeline including genomics, transcriptomics, proteomics, metabolomics, epigenomics, proteogenomics, interactomics, ionomics, phenomics, have become very handy nowadays. This is important produce climate-smart future crops proper understanding molecular responses genes, transcripts, proteins, epigenome, cellular metabolic circuits resultant phenotype. Instead mono-omics, two or more (hence 'multi-omics') integrated-omics approaches can decipher well. Multi-omics-characterized be used potent genetic resources incorporate into breeding program. For practical utility crop improvement, multi-omics particular combined genome-assisted (GAB) being pyramided improved yield, food quality associated agronomic open new era omics-assisted breeding. Thus, together are able processes, biomarkers, targets engineering, regulatory networks precision agriculture solutions crop's variable ensure security under changing circumstances.

Transcriptomics, proteomics, and metabolomics interventions prompt crop improvement against metal(loid) toxicity

Plant Cell Reports, Год журнала: 2024, Номер 43(3)

Опубликована: Фев. 27, 2024

The escalating challenges posed by metal(loid) toxicity in agricultural ecosystems, exacerbated rapid climate change and anthropogenic pressures, demand urgent attention. Soil contamination is a critical issue because it significantly impacts crop productivity. widespread threat of can jeopardize global food security due to contaminated supplies pose environmental risks, contributing soil water pollution thus impacting the whole ecosystem. In this context, plants have evolved complex mechanisms combat stress. Amid array innovative approaches, omics, notably transcriptomics, proteomics, metabolomics, emerged as transformative tools, shedding light on genes, proteins, key metabolites involved stress responses tolerance mechanisms. These identified candidates hold promise for developing high-yielding crops with desirable agronomic traits. Computational biology tools like bioinformatics, biological databases, analytical pipelines support these omics approaches harnessing diverse information facilitating mapping genotype-to-phenotype relationships under conditions. This review explores: (1) multifaceted strategies that use adapt their environment; (2) latest findings metal(loid)-mediated metabolomics studies across various plant species; (3) integration data artificial intelligence high-throughput phenotyping; (4) bioinformatics single and/or multi-omics integration; (5) insights into adaptations future outlooks; (6) capacity advances creating sustainable resilient thrive metal(loid)-contaminated environments.

Crop resilience measures must be strengthened in response to the global climate impact. Temperature stress exacerbates impact on crop growth and grain yield, threatening sustainability of grapevine production dependent wine industries. Grape (Vitis spp.) is one most widely cultivated fruit crops world, as well economically important fruit. However, grape yield quality are highly environmental conditions, particularly temperature stress. Understanding molecular mechanisms that control responses stresses development stress-resilient varieties have markedly advanced through rapid evolution high-throughput sequencing technologies, state-of-the-art multi-omics analytic platforms, automated phenotyping facilities. In current review, we summarized recent genomic progress omics-based breakthroughs grapes contributed abiotic tolerance via genetic strategies during last decades. Furthermore, delve into prospective challenges opportunities pertaining use multi-omics-based breeding aimed at designing climate-resilient varieties. Advances efficient de novo or re-domestication histories, characterization numerous trait genes using various omics tools, also discussed. By describing underlying adaptability future meet demand due population bursts following decades while keeping change mind, information will offer potential solutions for sustainable businesses.

Heterotrimeric G proteins – comprising Gα, Gβ, and Gγ subunits are ubiquitous elements in eukaryotic cell signaling. Plant genomes contain both canonical Gα subunit genes a family of plant-specific extra-large protein (XLGs) that encode consisting domain with Gα-like features downstream long N-terminal domain. In this review we summarize phenotypes modulated by the XLG arabidopsis highlight recent studies maize rice reveal dramatic phenotypic consequences clustered regularly interspaced short palindromic repeats (CRISPR) mutagenesis these important crop species. XLGs have redundant specific roles control agronomically relevant plant architecture resistance to abiotic biotic stresses. We also point out areas current controversy, suggest future research directions, propose revised, phylogenetically-based nomenclature for genes.

Salinity stress significantly affects rice yield, especially when it occurs during the germination stage. Direct seeding is an emerging method to conserve water in cultivation. However, date, there have been limited efforts screen germplasm for salt tolerance under this approach. In study, 40 genotypes were evaluated using a combination of and growth parameters. A total 59 microsatellite markers used assess genetic diversity, revealing significant variation both traits. Based on parameters, IR36, Sri Malaysia 2, MR185 performed well saline conditions, while Hashemi Tarom BAS2000 exhibited weak tolerance. MR219, MR211, MR263 identified as superior salt-tolerant against all MCHKAB salt-sensitive, showing reduced key traits, including root shoot development. Marker-based genotyping 287 alleles. The number alleles per locus ranged from two nine with average 4.86. polymorphic information content (PIC) four eight. RM21, RM481 RM566, RM488, RM9, RM217, RM333, RM242, RM209, RM38, RM539, RM475, RM267, RM279, RM430 found highly PIC value > 0.7 contain highest (≥6). Model- distance-based population structures inferred presence three clusters studied germplasm. cluster analysis, Shiroodi, Tarom, varieties, whereas MR211 MR219 are Malaysian varieties be tolerant high potential direct methods.
