“…Loss or gain of function in the BR biosynthetic DWARF (DWF) or BZR1 genes altered the timing of ROS production and PCD in tapetal cells, resulting in delayed or premature tapetal degeneration ( Yan et al, 2020 ). Basit et al (2022a) showed that seed priming with BRs and spermine (SPM) mitigated Cr toxicity by limiting its uptake in rice. BR and SPM application improved the seed germination rate, Chl content, PSII system, and total soluble sugars, minimizing ROS production, MDA content, and electrolyte leakage under Cr stress.…”

“…BR and SPM application improved the seed germination rate, Chl content, PSII system, and total soluble sugars, minimizing ROS production, MDA content, and electrolyte leakage under Cr stress. In addition, BRs and SPM controlled antioxidant enzyme and non-enzyme activities to diminish Cr-induced cellular oxidative losses ( Basit et al, 2022a ). Likewise, brassinosteroids insensitive 1 ( BRI1 ) is a BR receptor that triggers BR signaling.…”

Plant hormones and neurotransmitter interactions mediate antioxidant defenses under induced oxidative stress in plants

Due to global climate change, abiotic stresses are affecting plant growth, productivity, and the quality of cultivated crops. Stressful conditions disrupt physiological activities and suppress defensive mechanisms, resulting in stress-sensitive plants. Consequently, plants implement various endogenous strategies, including plant hormone biosynthesis (e.g., abscisic acid, jasmonic acid, salicylic acid, brassinosteroids, indole-3-acetic acid, cytokinins, ethylene, gibberellic acid, and strigolactones) to withstand stress conditions. Combined or single abiotic stress disrupts the normal transportation of solutes, causes electron leakage, and triggers reactive oxygen species (ROS) production, creating oxidative stress in plants. Several enzymatic and non-enzymatic defense systems marshal a plant’s antioxidant defenses. While stress responses and the protective role of the antioxidant defense system have been well-documented in recent investigations, the interrelationships among plant hormones, plant neurotransmitters (NTs, such as serotonin, melatonin, dopamine, acetylcholine, and γ-aminobutyric acid), and antioxidant defenses are not well explained. Thus, this review discusses recent advances in plant hormones, transgenic and metabolic developments, and the potential interaction of plant hormones with NTs in plant stress response and tolerance mechanisms. Furthermore, we discuss current challenges and future directions (transgenic breeding and genome editing) for metabolic improvement in plants using modern molecular tools. The interaction of plant hormones and NTs involved in regulating antioxidant defense systems, molecular hormone networks, and abiotic-induced oxidative stress tolerance in plants are also discussed.

“…In general, trace metal stress plants by oxidizing them either directly or indirectly by producing reactive oxygen species (ROS) (Qianqian et al, 2022). Cr toxicity causes oxidative damage in plants through overproduction of ROS such as O 2-, H 2 O 2 , and OH - (Shahid et al, 2017;Basit et al, 2022). The process of reducing Cr(VI) to lower oxidation states is the root cause of Cr toxicity, where only ROS are produced (Shanker et al, 2005;Shahzad et al, 2018).…”

Chromium toxicity, speciation, and remediation strategies in soil-plant interface: A critical review

In recent decades, environmental pollution with chromium (Cr) has gained significant attention. Although chromium (Cr) can exist in a variety of different oxidation states and is a polyvalent element, only trivalent chromium [Cr(III)] and hexavalent chromium [Cr(VI)] are found frequently in the natural environment. In the current review, we summarize the biogeochemical procedures that regulate Cr(VI) mobilization, accumulation, bioavailability, toxicity in soils, and probable risks to ecosystem are also highlighted. Plants growing in Cr(VI)-contaminated soils show reduced growth and development with lower agricultural production and quality. Furthermore, Cr(VI) exposure causes oxidative stress due to the production of free radicals which modifies plant morpho-physiological and biochemical processes at tissue and cellular levels. However, plants may develop extensive cellular and physiological defensive mechanisms in response to Cr(VI) toxicity to ensure their survival. To cope with Cr(VI) toxicity, plants either avoid absorbing Cr(VI) from the soil or turn on the detoxifying mechanism, which involves producing antioxidants (both enzymatic and non-enzymatic) for scavenging of reactive oxygen species (ROS). Moreover, this review also highlights recent knowledge of remediation approaches i.e., bioremediation/phytoremediation, or remediation by using microbes exogenous use of organic amendments (biochar, manure, and compost), and nano-remediation supplements, which significantly remediate Cr(VI)-contaminated soil/water and lessen possible health and environmental challenges. Future research needs and knowledge gaps are also covered. The review’s observations should aid in the development of creative and useful methods for limiting Cr(VI) bioavailability, toxicity and sustainably managing Cr(VI)-polluted soils/water, by clear understanding of mechanistic basis of Cr(VI) toxicity, signaling pathways, and tolerance mechanisms; hence reducing its hazards to the environment.

“…A concentration of 100 M Cr 6+ and below on rice seed ( Oryza sativa ) has no apparent effect on germination potential, and when the chromium treatment concentration is >25 mg L −1 , the seeds only germinated without root (Nath et al, 2009 ). The reason is that chromium sometimes triggers the protease activity resulting in the inhibition of seed germination because the hypocotyl transport is suppressed by the activity of amylase and sugar (Zeid, 2001 ; Dotaniya et al, 2014b ), and in low concentrations, it might promote the α-amylase activity, favoring germination by sugars and thus promoting seed germination (Nayari et al, 1997 ; Basit et al, 2022a ). The low concentration range is mostly between 0 and 10 mg/L.…”

In recent years, heavy metals-induced soil pollution has increased due to the widespread usage of chromium (Cr) in chemical industries. The release of Cr into the environment has reached its peak causing hazardous environmental pollution. Heavy metal-induced soil pollution is one of the most important abiotic stress affecting the dynamic stages of plant growth and development. In severe cases, it can kill the plants and their derivatives and thereby pose a potential threat to human food safety. The chromium ion effect on plants varies and depends upon its severity range. It mainly impacts the numerous regular activities of the plant's life cycle, by hindering the germination of plant seeds, inhibiting the growth of hypocotyl and epicotyl parts of the plants, as well as damaging the chloroplast cell structures. In this review article, we tried to summarize the possible effects of chromium-induced stress on plant growth, developmental physiology, biochemistry, and molecular regulation and provided the important theoretical basis for selecting remedial plants in chromium-induced contaminated soils, breeding of low toxicity tolerant varieties, and analyzing the mechanism of plant resistance mechanisms in response to heavy metal stress.
