MicroRNAs (miRNAs) constitute a novel mechanism of gene regulation affecting plant development, growth, and stress response. To study the role miRNAs in arsenic (As) stress, microarray profiling was performed Brassica juncea using custom Phalanx Plant OneArray™ containing 381 unique miRNA probes representing 618 from 22 species. hybridization roots exposed to As for 1h 4h revealed that total 69 belonging 18 families had significantly altered expression. The As-responsive also exhibited time-...
The mechanisms of perception arsenic (As)-induced stress and ensuing tolerance in plants remain unresolved. To obtain an insight into these mechanisms, biochemical transcriptional profiling two contrasting genotypes Brassica juncea was performed. After screening 14 varieties for As tolerance, one tolerant (TPM-1) sensitive (TM-4) variety were selected exposed to arsenate [As(V)] arsenite [As(III)] 7 d 15 analyses. demonstrated higher accumulation upon exposure both 500 μM As(V) 250 As(III)...
Zinc is an essential element that also renowned for widespread contamination and toxicity at high concentrations. The present study was carried out to analyze the responses induced by lower, as well higher, doses of zinc (0–200 mg/L), in form oxide nanoparticles (ZnO NPs) wheat maize, a period 21 days. Accumulation increases with increasing Zn both higher being (121 mg/kg root 66 shoot) than maize (95 48 shoot). activity alpha-amylase showed increase, while dehydrogenase decline, response...
Arsenic (As) is a toxic metalloid classified as group 1 carcinogen. The presence of As in high concentrations paddy soil and irrigation water results into accumulation rice grains posing threat to the health millions people worldwide. main reason for contamination biogeochemical weathering rocks release bound groundwater. Human intervention through intensive agricultural practices excessive groundwater consumption have contributed greatly prevailing contamination. flooded cultivation...
Coronaviruses are the well-known cause of severe respiratory, enteric and systemic infections in a wide range animal hosts including man. The scientific interest on coronaviruses has increased since outbreak COVID-19 (SARS-CoV-2) that initiated Wuhan, China. This was soon declared 'Public Health Emergency International Concern' by World Organisation (WHO). Presently, best strategy against this pandemic is prevention through regular hand face washes, use masks, gloves personal protective...
The consequences of heavy metal contamination are progressively degrading soil quality in this modern period industry. Due to reason, improvement the is necessary. Remediation a method removing pollutants from root zone plants order minimize stress and increase yield grown it. use remove toxins soil, such as metals, trace elements, organic chemicals, radioactive substances, referred bioremediation. Biochar fly ash techniques also studied for effectiveness improving contaminated soil. This...
Multifunctional plant growth-promoting bioinoculants are used to enhance growth, harvest yields, and add economic value agricultural crops. In this study, such bioinoculant, BC-II-20 ( Pseudomonas sp.), was isolated from the rhizospheric soil of a medicinal Bergenia ciliata Garhwal Himalayas, Uttarakhand, India. After characterization, supplementation with sp. study growth stimulation in commercially important plant, Andrographis paniculata (Kalmegh), it depicted enhanced physiological...
Abstract Nanotechnology is a rapidly developing discipline that has the potential to transform way we approach problems in variety of fields, including agriculture. The use nanotechnology sustainable agriculture gained popularity recent years. It various applications agriculture, such as development nanoscale materials and devices boost agricultural productivity, enhance food quality safety, improve efficiency water nutrient usage, reduce environmental pollution. proven be very beneficial...
Soil health is the foundation of sustainable agriculture, and its preservation paramount in global arsenic (As) contamination challenges. As a critical issue for environmental agricultural sustainability. Rapid urbanization industrial expansion release toxic heavy metal(loid)s, including As, into soil. Arsenic disrupts rhizosphere ecosystem, affecting plant health, microbial communities, overall soil functionality. Ensuring face imperative human well-being developing resilient, environment....
