Multi-Omics Approaches Against Abiotic and Biotic Stress—A Review

Plants, Journal Year: 2025, Volume and Issue: 14(6), P. 865 - 865

Published: March 10, 2025

Plants face an array of environmental stresses, including both abiotic and biotic stresses. These stresses significantly impact plant lifespan reduce agricultural crop productivity. Abiotic such as ultraviolet (UV) radiation, high low temperatures, salinity, drought, floods, heavy metal toxicity, etc., contribute to widespread losses globally. On the other hand, those caused by insects, fungi, weeds, further exacerbate these challenges. stressors can hinder systems at various levels, molecular, cellular, development processes. To overcome challenges, multi-omics computational approaches offer a significant tool for characterizing plant’s biomolecular pool, which is crucial maintaining homeostasis signaling response changes. Integrating multiple layers omics data, proteomics, metabolomics, ionomics, interactomics, phenomics, simplifies study resistance mechanisms. This comprehensive approach enables regulatory networks pathway maps, identifying potential targets improving through genetic engineering or breeding strategies. review highlights valuable insights from integrating unravel stress responses factors. By decoding gene regulation transcriptional networks, techniques reveal critical mechanisms underlying tolerance. Furthermore, role secondary metabolites in bio-based products enhancing mitigation discussed.

Plants other than animal-pollinated herbs provide wild bees with vital nutrients

Global Ecology and Conservation, Journal Year: 2024, Volume and Issue: 52, P. e02984 - e02984

Published: May 10, 2024

Adult pollinators that forage primarily for energy have traditionally guided our understanding of plant–pollinator interactions, leading to assumptions about the importance different plants pollinators. Consequently, pollinator conservation strategies potentially overlook balance juvenile diets. I studied a representative bee, Osmia bicornis, explore contributions various nutritional quality diet. Using ecological stoichiometry and micronutrient ecology, investigated proportions vital body-building chemical elements (C, N, P, S, K, Na, Ca, Mg, Fe, Zn, Mn Cu; henceforth "nutrients") in larval pollen loads. considered botanical origin, location sexual dimorphism niche as factors influencing nutrient Redundancy analysis indicated main factor determining proportion was which accounted 70.17% variation; contributed 20.21%, sex 8.43%. Among 30 taxa composing loads, determinants content were oak, maple, chestnut, cabbage family, buttercup, grasses. Trees wind-pollinated provided important nutrients.

Uncovering the significance of the ratio of food K:Na in bee ecology and evolution

Ecology, Journal Year: 2023, Volume and Issue: 104(8)

Published: May 26, 2023

Abstract Bees provide important ecological services, and many species are threatened globally, yet our knowledge of wild bee ecology evolution is limited. While evolving from carnivorous ancestors, bees had to develop strategies for coping with limitations imposed on them by a plant‐based diet, nectar providing energy essential amino acids pollen as an extraordinary, protein‐ lipid‐rich food nutritionally similar animal tissues. Both display one characteristic common plants, high ratio potassium sodium (K:Na), potentially leading underdevelopment, health problems, death. We discuss why how the K:Na contributes considering this factor in future studies will new knowledge, more accurately depicting relationship their environments. Such understanding plants function interact needed effectively protect bees.

The Plant Ionome as a Functional Trait: Variation across Bioclimatic Regions and Functional Groups

Physiologia Plantarum, Journal Year: 2025, Volume and Issue: 177(1)

Plant chemical composition is a trait gaining increasing importance in plant ecology. However, there limited research on the patterns and drivers of its variation among different functional groups bioclimatic regions. We conducted an analysis ionomes utilising X-ray fluorescence 83 species from four distinct (grasses, legumes, forbs woody species); we marked plots across 15 sites located both desert Mediterranean The primary factors influencing variations are predominantly attributed to rather than soil composition. Across all groups, plants region characterised by greater association with calcium, whereas exhibit higher affinity for strontium (Sr), suggesting potential role drought tolerance. Among grasses uniquely ionomic features, primarily due their silicon (Si) concentrations. species' affinities certain elements interactions likely driven physiological constraints, within group mostly environmental conditions. conclude that form phenotypes shaped natural selection under large-scale variability, making ionome important trait.

Comparison of inductively coupled plasma mass spectrometry and molybdenum blue colorimetry for total phosphorus determination in freshwater invertebrates

PLoS ONE, Journal Year: 2025, Volume and Issue: 20(1), P. e0317871 - e0317871

Published: Jan. 28, 2025

Molybdenum blue colorimetry (MBC) is the dominant, well-established method used for determining total P in environmental media, including organismal tissues. However, other elemental methods determination are available, inductively coupled plasma mass spectrometry (ICP-MS). Given extensive literature using MBC to determine samples, it important assess analyses by ICP-MS and ensure that two produce comparable data. In this work, we compared freshwater invertebrates, potential analytical interferences, applying both three standard reference materials (SRMs) 106 invertebrate samples. Average recoveries SRMs were slightly higher (99.8 ± 5.2%) than (96.5 5.4%), but indicated good accuracy. Total invertebrates determined was strongly linearly correlated ( r = 0.96) with a slope of 1.01. On whole, measured exceeded MBC, average pair-wise differences %P biologically negligible (0.044 0.054). samples run on kinetic energy discrimination modes favorably (e.g., SRM recovery 102% methods), indicating influence polyatomic ions analysis. Similarly, analysis spike (100.2 3.4%) (107.0 2.8%) considered acceptable. We conclude represents reliable alternative while also offering opportunity measure additional relevant elements single
