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

Genes, Journal Year: 2023, Volume and Issue: 14(6), P. 1281 - 1281

Published: June 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.

Heavy metal concentrations exceeding permissible limits threaten human life, plant and all other life forms. Different natural anthropogenic activities emit toxic heavy metals in the soil, air, water. Plants consume from their roots foliar part inside plant. may interfere with various aspects of plants, such as biochemistry, bio-molecules, physiological processes, which usually translate into morphological anatomical changes. They use strategies to deal effects contamination. Some these include restricting cell wall, vascular sequestration, synthesis biochemical compounds, phyto-chelators organic acids, bind free moving ions so that are minimized. This review focuses on several genetics, molecular, signaling levels, integrate produce a coordinated response toxicity interpret exact behind tolerance stress. It is suggested some model species must be thoroughly studied comprehend approaches put knowledge practical use.

Heavy metal stress and mitogen activated kinase transcription factors in plants: Exploring heavy metal‐ROS influences on plant signalling pathways

Plant Cell & Environment, Journal Year: 2024, Volume and Issue: 47(8), P. 2793 - 2810

Published: April 23, 2024

Due to their stationary nature, plants are exposed a diverse range of biotic and abiotic stresses, which heavy metal (HM) stress poses one the most detrimental targeting plant processes. HMs instigate overproduction reactive oxygen species (ROS), mitigate adverse effects ROS, induce multiple defence mechanisms. Besides negative implications these molecules play multitude signalling roles in plants, acting as central player complex network cells. One ROS-associated mechanisms is mitogen-activated protein kinase (MAPK) cascade, pathway transduces extracellular stimuli into intracellular responses. Plant MAPKs have been implicated involved response, phytohormone regulation, cell cycle cues. However, influence various on MAPK activation has not well documented. In this review, we address summarise several aspects related HM-induced ROS signalling. Additionally, touch how signals activate cascade downstream transcription factors that responses HMs. Moreover, propose workflow could characterise genes associated with during HM

Coptis chinensis Franch is a perennial herb from the Ranunculaceae family with long history of medicinal use. As part, rhizome coptis often accumulates excessive cadmium (Cd) even at low concentrations in soil, which not only compromises its safety but also raises concerns about adverse effects on human health. Therefore, effective strategies are needed to mitigate this accumulation and ensure safe use traditional medicine.

Due to anthropogenic activities, environmental pollution of heavy metals/metalloids (HMs) has increased and received growing attention in recent decades. Plants HM-contaminated soils have slower growth development, resulting lower agricultural yield. Exposure HMs leads the generation free radicals (oxidative stress), which alters plant morpho-physiological biochemical pathways at cellular tissue levels. evolved complex defense mechanisms avoid or tolerate toxic effects HMs, including absorption accumulation cell organelles, immobilization by forming complexes with organic chelates, extraction via numerous transporters, ion channels, signaling cascades, transcription elements, among others. Nonetheless, these internal defensive are insufficient overcome toxicity. Therefore, unveiling adaptation tolerance is necessary for sustainable agriculture. Recent breakthroughs cutting-edge approaches such as phytohormone gasotransmitters application, nanotechnology, omics, genetic engineering tools identified molecular regulators linked tolerance, may be applied generate HMs-tolerant future plants.
