Article Synopsis
  • - The study investigates how heavy metal stress affects chickpea growth and health, focusing on two varieties: a sensitive one (ILC 482) and a tolerant one (Azkan), particularly through analyzing microRNA responses.
  • - Heavy metal exposure (especially from cadmium, arsenic, and nickel) led to reduced growth and increased damage in both chickpea types, with ILC 482 showing greater sensitivity than Azkan.
  • - The research highlights significant interactions between plant genotype and heavy metal treatment, noting the importance of antioxidant enzyme activities and oxidative stress markers like hydrogen peroxide and malondialdehyde in assessing plant response to stress.

Article Synopsis
  • Chitosan (CTS) is a natural alternative for improving agricultural practices by preventing toxic metal uptake in plants, specifically addressing cadmium (Cd) stress in pepper plants.
  • The study found that Cd exposure reduced growth and chlorophyll levels while increasing stress indicators like proline and certain antioxidant enzymes.
  • Applying CTS reduced Cd absorption, lowered stress factors like hydrogen peroxide and abscisic acid, and enhanced growth and hormone levels in pepper plants, suggesting it can help mitigate the negative effects of Cd stress.

Agricultural land contaminated with heavy metals such as non-biodegradable arsenic (As) has become a serious global problem as it adversely affects agricultural productivity, food security and human health. Therefore, in this study, we investigated how the administration of N-acetyl-cysteine (NAC), regulates the physio-biochemical and gene expression level to reduce As toxicity in lettuce. According to our results, different NAC levels (125, 250 and 500 μM) significantly alleviated the growth inhibition and toxicity induced by As stress (20 mg/L).
