Summary: This study investigated the phenotyping of chromium (Cr) resistance in rice and identified rice cultivars with good seed germination vigor. The results showed that some rice cultivars exhibited moderate sensitivity and tolerance to Cr toxicity, while others showed the highest sensitivity and tolerance. Furthermore, it was found that a hybrid rice variety (HV14) exhibited less reduction in chlorophyll pigments induced by Cr compared to other varieties. HV14 modulated the antioxidant defense mechanism, reduced ROS accumulation, and increased total soluble sugar level, resulting in reduced electrolyte leakage.

Summary: Copper (Cu) bioavailability in agricultural systems can be limited, leading to imbalances in plant production. This study found that the combined application of vegetable protein hydrolysate (VPH) and copper complexed with peptides and amino acids (Cu-VPH) significantly increased the yield and photosynthetic performance of basil plants. Furthermore, it increased the copper and other mineral content in the plants. These findings emphasize the importance of optimizing agricultural interventions.

Summary: The study compared the effects of microplastics on microalgae from different habitats. The results showed that microplastics had a significant concentration effect on the growth of microalgae, inhibiting photosynthesis and activating the antioxidant system. The effects on freshwater microalgae were found to be more severe than on marine microalgae. This study provides reliable data for understanding the complex effects of microplastics on microalgae and comparing the differential effects among different microalgae.

Summary: The study found that when Callistemon citrinus plants were irrigated with a CaCl2 solution, the leaf morpho-anatomical structure could not maintain high photosynthetic performance under high salt conditions compared to plants treated with an iso-osmotic NaCl solution. The data collected suggest a close relationship between anatomical traits and eco-physiological strategies in maintaining photosynthetic efficiency under saline stress conditions, highlighting the fundamental role of leaf anatomy in setting the limits of plant physiology.

Summary: Growth stimulating bacteria can assist in remediating dry and arid soil, as well as alleviating plant stress. They enhance soil carbon flux, chlorophyll levels, net photosynthetic rate, and stomatal conductance. Additionally, the bacteria improve leaf growth, but reduce root biomass under drought conditions. By increasing antioxidant enzymatic activities and mineral acquisition, the bacteria protect plants from oxidative stress and enhance their overall growth potential.

Summary: Cadmium (Cd) toxicity hinders plant growth, but treatment with biostimulant and zinc oxide nanoparticles (ZnPs) improves biomass, chlorophyll content, and antioxidants in maize. The combination of biostimulant and ZnPs shows synergistic effects in Cd remediation, enhancing nutrient uptake and reducing structural cell damage. Zinc oxide positively regulates various proteins involved in energy generation, channel formation, localization, and stress response in maize, suggesting its ideal role as a protein interactor in plant physiology.

Summary: Polyamines (PAs) and nitric oxide (NO) play crucial roles in improving stress tolerance and maintaining growth and development in plants. They protect plants through activation of stress adaptation strategies such as membrane stabilisation, acid neutralisation, and suppression of ROS generation. NO interacts with PAs during developmental processes and stress responses. Supplementation of PAs to plants increases NO content. The exact mechanisms of the interrelation between NO and PAs are currently unknown. Understanding the crosstalk between PAs and NO can provide better tolerance to plants against stressful environments.

Summary: Recently, the use of salicylic acid (SA) to enhance plant resistance to abiotic stresses has become more prevalent. Global salt stress severely affects 2.1% of irrigated land (19.5% of total land). Wheat (Triticum aestivum) production in 2020 reached 761 million tons, making it the second most produced cereal after maize. The application of SA significantly increased photosynthetic attributes and antioxidant enzyme activity while interacting with meristematic cells. Further research is needed to understand the mechanisms of SA in wheat plants under stress.

Summary: This study aimed to assess the toxicity of Chlorpyrifos (CP) on Brassica juncea L. and investigate the ameliorative potential of phytohormone, 24-epi-brassinolide (EBL) mediated plant-microbe interaction in B. juncea L. The results showed that EBL and B2 treatment significantly increased the content of chlorophyll, carotenoids, flavonoids, anthocyanins, and xanthophylls in CP-stressed B. juncea seedlings. The supplementation of EBL and PGPR improved the expression of genes related to photosynthetic pigments and metabolic pathways. These findings suggest that EBL and PGPR can reduce CP-induced toxicity and promote recovery in B. juncea seedlings.

Summary: The increasing concentration of heavy metals (HMs) due to human activities is a serious problem, affecting plants along with other abiotic stresses. Meeting the nutritional demands of a growing population under these adverse conditions is crucial. Soil remediation of HMs is costly and unsustainable, but applying nanobionics to enhance plant stress tolerance shows promise. This review highlights the impact of nanobionics on plant physiological traits, growth indices, and discusses associated concerns and stress tolerance.

Summary: The goal of this study was to investigate the influence of flower structure and nectar composition on the reproductive success of Epipactis helleborine orchids in natural and anthropogenic habitats. We found that anthropogenic populations had higher fruiting rates and different pollinaria removal rates compared to natural populations. Floral display and flower traits showed limited effects on reproductive success, with nectar chemistry being the most important trait. The nectar of E. helleborine had lower sugar concentration in anthropogenic populations and a dominance of sucrose in natural populations.

Summary: Microplastic accumulation in the soil-plant system can stress plants and affect product quality. The effect of microplastics on plants is inconsistent and the molecular mechanisms are unknown. This study investigated the molecular mechanism underlying the growth of soybean plants in soil contaminated with microplastics and arbuscular mycorrhizal fungi. The results showed that microplastic stress led to a decline in plant growth, chlorophyll content, and soybean yield. Microplastic addition caused oxidative stress and inhibited rubisco and root activity. However, arbuscular mycorrhizal fungi inoculation alleviated the phytotoxic effects of microplastics, induced the plant defense system, and upregulated genes responsible for metal uptake in soybean.
