Boron Toxicity and Deficiency in Agricultural Plants

International Journal of Molecular Sciences, Journal Year: 2020, Volume and Issue: 21(4), P. 1424 - 1424

Published: Feb. 20, 2020

Boron is an essential plant micronutrient taken up via the roots mostly in form of boric acid. Its important role metabolism involves stabilization molecules with cis-diol groups. The element involved cell wall and membrane structure functioning; therefore, it participates numerous ion, metabolite, hormone transport reactions. has extremely narrow range between deficiency toxicity, inadequate boron supply exhibits a detrimental effect on yield agricultural plants. problem can be solved by fertilization, whereas soil toxicity ameliorated using various procedures; however, these approaches are costly time-consuming, they often show temporary effects. Plant species, as well genotypes within dramatically differ terms requirements; thus, available which deficient for one crop may exhibit toxic effects another. widely documented intraspecies genetic variability regarding utilization efficiency tolerance, together knowledge physiology genetics boron, should result development efficient tolerant varieties that represent long-term sustainable solution or excess supply.

Abiotic Stress in Crop Species: Improving Tolerance by Applying Plant Metabolites

Plants, Journal Year: 2021, Volume and Issue: 10(2), P. 186 - 186

Published: Jan. 20, 2021

Reductions in crop yields brought about by abiotic stress are expected to increase as climate change, and other factors, generate harsher environmental conditions regions traditionally used for cultivation. Although breeding genetically modified edited organisms have generated many varieties with greater tolerance, their practical use depends on lengthy processes, such biological cycles legal aspects. On the hand, a non-genetic approach improve yield involves exogenous application of natural compounds, including plant metabolites. In this review, we examine recent literature related different primary (proline, l-tryptophan, glutathione, citric acid) secondary (polyols, ascorbic acid, lipoic glycine betaine, α-tocopherol, melatonin) metabolites improving tolerance stress. We focus drought, saline, heavy metal, temperature parameters that forecast become more extreme or frequent continues alter. The benefits applications often evaluated measuring effects metabolic, biochemical, morphological variety plants, which usually result improved when applied greenhouse field. As strategy has proven be an effective way raise stress, also discuss prospect its widespread implementation short term.

Plant stress response and adaptation via anthocyanins: A review

Plant Stress, Journal Year: 2023, Volume and Issue: 10, P. 100230 - 100230

Published: Sept. 19, 2023

Global climate change has caused an increase in extreme weather events and subjected plants to a variety of abiotic stress. Plants being rooted the soil are unable avoid stress by relocation. Therefore, have evolved sophisticated mechanisms cope with that negatively affects photosynthesis, respiration, cell water potential, eventually normal growth development. Anthocyanins, kind flavonoid, water-soluble natural pigments various colors plants, which can safeguard from wide range environmental Anthocyanins antioxidant functions play indispensable role scavenging reactive oxygen species (ROS). Moreover, anthocyanins act as "sunscreens" form chelates metals/metalloids alleviate metal Nonetheless, biosynthesis stability affected external factors. Here, we review regulatory anthocyanin synthesis, effects factors on production, response including drought, salt stress, high light intensity, ultraviolet rays, heavy metals, low temperature. Considering important tolerance, increasing content manipulating genes potentially be useful improve plant resistance, putative solutions for resilience environments today future.

Phytochelatins: Sulfur-Containing Metal(loid)-Chelating Ligands in Plants

International Journal of Molecular Sciences, Journal Year: 2023, Volume and Issue: 24(3), P. 2430 - 2430

Published: Jan. 26, 2023

Phytochelatins (PCs) are small cysteine-rich peptides capable of binding metal(loid)s via SH-groups. Although the biosynthesis PCs can be induced in vivo by various metal(loid)s, mainly involved detoxification cadmium and arsenic (III), as well mercury, zinc, lead, copper ions, which have high affinities for S-containing ligands. The present review provides a comprehensive account recent data on PC biosynthesis, structure, role metal(loid) transport sequestration vacuoles plant cells. A comparative analysis accumulation hyperaccumulator plants, accumulate their shoots, excluders, roots, investigates question whether endogenous concentration determines plant's tolerance to metal(loid)s. Summarizing available data, it concluded that not hyperaccumulation machinery, though they play key homeostasis. Unraveling physiological metal(loid)-binding ligands is fundamental problem modern molecular biology, physiology, ionomics, toxicology, important development technologies used phytoremediation, biofortification, phytomining.

In recent years, heavy metals (HMs) attain lot of consideration due to their toxic nature in the environment. Natural as well anthrpogenic activities like urbanization & industrialization, use fertilizers, and waste managemgemt contamination increased HMs exposure living organisms. Due continous encountering with HMs, plants facing oxidative stress, nutritional imbalance, metaolic disturbance yield lost. Only, limited concentration are tolerable for plants, whereas higher these disrupted metabolic cellular plants. To overcome toxicity have a molecule name phytochelatins (PCs). PCs important HM detoxification maintain integrity. They prompted reaction management. It involved metal chelation sequestration cytosol vacuoles, respectively.
