Amid escalating challenges from global climate change and increasing environmental degradation, agricultural systems worldwide face a multitude of abiotic stresses, including drought, salinity, elevated temperatures, heavy metal pollution, and flooding. These factors critically impair crop productivity and yield. Simultaneously, biotic pressures such as pathogen invasions intensify the vulnerability of agricultural outputs.

Background: Diseases in humans caused by amphizoic amoebae that can result in visual impairment and even blindness, have recently been identified more frequently worldwide. Etiologically complex incidents of keratitis, including those connected with strains detected in Poland, were evaluated in this study.
Methods: Corneal samples from cases resistant to antimicrobial therapy assessed for epidemiological, microbiological and parasitological aspects were investigated by phase-contrast microscope, slit lamp and by confocal microscopy.

This study investigated the effects of chitosan/gelatin (CG) coatings containing pomegranate peel extract (PPE) on the physical-chemical, microbiological, volatile profile, and sensory characteristics of strawberries over 12 days of refrigerated storage. The coatings containing PPE minimized the weight loss of the fruits by 11 % and delayed their fungal contamination by 6-8 days. Uncoated fruits showed soluble solids content, pH, and titratable acidity values characteristics of highly deteriorated fruits.

Micromycetes from the genus Alternaria are commonly found in plant food raw materials, and their produced emerging mycotoxins (EMT) pose a risk to human health. Based on polyphase taxonomy, we studied the species composition of the Alternaria spp. population in samples of Russian grain and berries; non-toxinogenic species of Alternaria of the Infectoriae section and toxinogenic species of the Alternaria section were found.

Article Synopsis
- Cotton has potential for cleaning copper-polluted soil, yet its tolerance mechanisms to copper toxicity remain unclear.
- Two cotton lines, A2304 (Cu-tolerant) and A1415 (Cu-sensitive), were studied for their morphological and physiological responses to copper excess, revealing A2304's superior antioxidant activities and lower reactive oxygen species.
- A2304 exhibited smarter gene expression changes for copper handling, reducing active copper ion concentrations while maintaining similar overall copper uptake compared to A1415, thus potentially mitigating copper toxicity effects.
