Aluminum (Al) toxicity is one of the factors limiting alfalfa production on acid soils. This study aims to investigate the different mechanisms in growth, Al content, pectin content, pectin methylesterase (PME) and the degree of pectin methyl-esterification (DM) in the two root segments of different ecotypes alfalfa during the time of Al stress. It was found interesting that lower root elongation and higher Al content were observed in the Al-sensitive ecotype compared to the Al-resistant ecotype of alfalfa. The Al accumulation increased with the increased of stress time. Meanwhile, the pectin and PME activity of cell wall significantly increased. While DM in Al-sensitive ecotype decreased, more free pectin acid residues on the cell wall of Al-sensitive ecotype. The Al content was higher in 0-5 mm root segments and the cell wall for both materials. The increase in pectin content and PME activity along with the decrease in DM in this segment could determine the alfalfa sensitivity to Al more effectively. The correlation analysis showed that there was a relationship between Al content, pectin content, PME activity of cell wall and DM. The different temporal dynamics and spatial differences caused the increase of Al content, pectin content and cell wall PME activity, changes of DM under Al toxicity cooperates to determine the difference of Al resistance that confers different ecotypes of alfalfa.

A wide variety of bacteria are present in soil but in rhizospheric area, the majority of microbes helps plant in defending diseases and facilitate nutrient uptake. These microorganisms are supported by plants and they are known as plant growth-promoting rhizobacteria (PGPR). The PGPRs have the potential to replace chemical fertilizers in a way that is more advantageous for the environment. Fluoride (F) is one of the highly escalating, naturally present contaminants that can be hazardous for PGPRs because of its antibacterial capacity. The interactions of F with different bacterial species in groundwater systems are still not well understood. However, the interaction of PGPR with plants in the rhizosphere region reduces the detrimental effects of pollutants and increases plants’ ability to endure abiotic stress. Many studies reveal that PGPRs have developed F defense mechanisms, which include efflux pumps, Intracellular sequestration, enzyme modifications, enhanced DNA repair mechanism, detoxification enzymes, ion transporter/antiporters, F riboswitches, and genetic mutations. These resistance characteristics are frequently discovered by isolating PGPRs from high F-contaminated areas or by exposing cells to fluoride in laboratory conditions. Numerous studies have identified F-resistant microorganisms that possess additional F transporters and duplicates of the well-known targets of F. Plants are prone to F accumulation despite the soil’s low F content, which may negatively affect their growth and development. PGPRs can be used as efficient F bioremediators for the soil environment. Environmental biotechnology focuses on creating genetically modified rhizobacteria that can degrade F contaminants over time. The present review focuses on a thorough systemic analysis of contemporary biotechnological techniques, such as gene editing and manipulation methods, for improving plant-microbe interactions for F remediation and suggests the importance of PGPRs in improving soil health and reducing the detrimental effects of F toxicity. The most recent developments in the realm of microbial assistance in the treatment of F-contaminated environments are also highlighted.
