Climate change is a defining challenge of the 21st century, and this decade critical time for action to mitigate worst effects on human populations ecosystems. Plant science can play an important role in developing crops with enhanced resilience harsh conditions (e.g. heat, drought, salt stress, flooding, disease outbreaks) engineering efficient carbon-capturing carbon-sequestering plants. Here, we present examples research being conducted these areas discuss challenges open questions as call plant community.

Multi-Omics Pipeline and Omics-Integration Approach to Decipher Plant’s Abiotic Stress Tolerance Responses

Genes, Год журнала: 2023, Номер 14(6), С. 1281 - 1281

Опубликована: Июнь 16, 2023

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.

Regulatory networks in plant responses to drought and cold stress

PLANT PHYSIOLOGY, Год журнала: 2024, Номер 195(1), С. 170 - 189

Опубликована: Март 21, 2024

Abstract Drought and cold represent distinct types of abiotic stress, each initiating unique primary signaling pathways in response to dehydration temperature changes, respectively. However, a convergence at the gene regulatory level is observed where common set stress-responsive genes activated mitigate impacts both stresses. In this review, we explore these intricate networks, illustrating how plants coordinate stress signals into collective transcriptional strategy. We delve molecular mechanisms perception, signaling, activation pathways, with focus on insights gained from model species. By elucidating shared aspects plant responses drought cold, provide insight adaptive strategies plants, paving way for engineering stress-resilient crop varieties that can withstand changing climate.

Gene-by-environment interactions in plants: Molecular mechanisms, environmental drivers, and adaptive plasticity

The Plant Cell, Год журнала: 2022, Номер 35(1), С. 109 - 124

Опубликована: Ноя. 7, 2022

Abstract Plants demonstrate a broad range of responses to environmental shifts. One the most remarkable is plasticity, which ability single plant genotype produce different phenotypes in response stimuli. As with all traits, plasticity evolve depends on presence underlying genetic diversity within population. A common approach for evaluating role variation driving differences has been study genotype-by-environment interactions (G × E). G E occurs when genotypes phenotypic trait values environments. In this review, we highlight progress and promising methods identifying key drivers E. Specifically, methodological advances using algorithmic multivariate approaches understand combined new genomic innovations can greatly increase our understanding about molecular These developing be applied proliferating garden networks that capture natural gradients unravel mechanisms An increased used enhance resilience productivity agronomic systems.

OsNAC5 orchestrates OsABI5 to fine‐tune cold tolerance in rice

Journal of Integrative Plant Biology, Год журнала: 2023, Номер 66(4), С. 660 - 682

Опубликована: Ноя. 16, 2023

Due to its tropical origins, rice (Oryza sativa) is susceptible cold stress, which poses severe threats production. OsNAC5, a NAC-type transcription factor, participates in the stress response of rice, but detailed mechanisms remain poorly understood. Here, we demonstrate that OsNAC5 positively regulates tolerance at germination and seedlings by directly activating expression ABSCISIC ACID INSENSITIVE 5 (OsABI5). Haplotype analysis indicated single nucleotide polymorphisms NAC-binding site OsABI5 promoter are strongly associated with tolerance. also enhanced stability, thus regulating cold-responsive (COR) genes, enabling fine-tuned control action for rapid, precise plant responses stress. DNA affinity purification sequencing coupled transcriptome deep identified several target genes involved COR expression, including DEHYDRATION-RESPONSIVE ELEMENT BINDING FACTOR 1A (OsDREB1A), OsMYB20, PEROXIDASE 70 (OsPRX70). In vivo vitro analyses suggested gene transcription, marked upregulation OsNAC5-overexpressing lines downregulation osnac5 and/or osabi5 knockout mutants. This study extends our understanding regulation via through OsABI5-CORs module, may be used ameliorate advanced breeding.
