Summary: In this study, bacteria from the genus of Azotobacter, Bacillus and Pseudomonas were isolated from Phaseolus vulgaris roots and used as plant growth-promoting bacteria for various plants. The results showed that different bacteria had different effects on plant growth in both sterile and non-sterile soil. Bacillus had the most influence on Sinapis alba in sterile soil, while Pseudomonas had the greatest effect on root and shoot length in non-sterile soil. Azotobacter stimulated the growth of Brassica napus in non-sterile soil, while Bacillus had a positive effect on Amaranthus retroflexus. Azotobacter also promoted the growth of Rumex patientia and Panicum miliaceum, while Pseudomonas enhanced the growth of Linum usitatissimum in non-sterile soil. However, not all differences observed in plants with the selected bacteria were statistically significant compared to the control.

Summary: Nitrogen and phosphorus are essential nutrients for vegetation ecosystem but often insufficient in soil. Chemical fertilizers pose environmental risks, making plant growth-promoting rhizobacteria (PGPR) an environmentally friendly alternative. Rhizospheric diazotrophs fix nitrogen and promote plant growth, while phosphate-solubilizing bacteria enhance plant phosphorus uptake. Research into the mechanisms and influences of rhizospheric nitrogen fixation (NF) and phosphate solubilization by PGPR is lacking. Further genetic research and co-inoculation with diazotrophs and PSB strains can enhance soil nutrient sustainability.

Summary: Arsenic contamination in soil and water is a global problem with detrimental effects on crops and human health. Different transporters, such as Lsi1, Lsi2, and Lsi6, are involved in the transfer of arsenic from soil to rice grains. Various mitigation strategies, including the use of bacteria, fungi, nanoparticles, and specific plant genotypes, have been employed to reduce arsenic levels in crops. Factors like nitric oxide, Fe, and jasmonate also influence plant response to arsenic-induced oxidative stress. This review highlights the importance of understanding the biochemical, molecular, and physiological effects of arsenic on plants and the need for further research on effective remediation methods.

Summary: The climate crisis and unsustainable agricultural practices have led to decreased soil fertility and crop yield. Agricultural lands also contribute significantly to greenhouse gas emissions. Biochar can help address these issues by neutralizing carbon, restoring the environment, and managing agriculture. The relationship between biochar, soil microbial communities, and rhizosphere functions is complex and still not fully understood. This review explores the role of biochar in mitigating climate change, increasing carbon sequestration, and supporting crop productivity, as well as its potential in reducing soil microplastics and heavy metal contamination.

Summary: This study investigated the effect of calcium chloride (CaCl2) treatment on GABA accumulation in fresh-cut cantaloupe and the underlying mechanisms. The results showed that CaCl2 treatment increased GABA content and the activities of GAD and SSADH enzymes, while reducing glutamate content and GABA-T activity. Additionally, CaCl2 treatment upregulated the expressions of CmCML11 and CmCAMTA5, as well as several GABA shunt genes, through the transcriptional activation by CmCAMTA5. Furthermore, the interaction between CmCML11 and CmCAMTA5 enhanced the transcriptional activation of GABA shunt genes. Overall, this study reveals that CaCl2 treatment promotes GABA accumulation in fresh-cut cantaloupe through the combined effect of CmCML11 and CmCAMTA5 in regulating the expressions of GABA shunt genes.

Summary: This study identified the high nitrogen use efficiency (NUE) black sesame variety 17-156 and analyzed its underlying physiological and molecular mechanisms. The results showed that 17-156 possesses a sophisticated nitrogen metabolizing machinery to uptake and assimilate higher quantities of inorganic nitrogen, simultaneously improving carbon metabolism and growth. Many important genes were up-regulated in 17-156 under high nitrogen condition. Additionally, 38 potential candidate genes were identified for future studies to improve sesame's NUE. These findings provide valuable resources for understanding the regulatory network of nitrogen metabolism and developing sesame cultivars with improved NUE.

Summary: Selenium (Se) can reduce uptake and translocation of cadmium (Cd) in plants by regulating root morphology. This study investigated the effects of Se(IV) on root exudates, root morphology, root endogenous hormones, and Cd uptake efficiency in rice under Cd stress. The results showed that Se(IV) significantly reduced Cd concentrations in shoots and roots, and decreased Cd uptake efficiency via root hairs. Se(IV) also affected root morphology, root exudates, and the synthesis of hormones like IAA and JA. However, transcriptome analysis revealed no upregulated differentially expressed genes (DEGs) in IAA synthesis.
