“…Ruiz-Lozano et al (2001) observed that soybean plants inoculated with AMF could cope better with premature nodule senescence induced by drought stress. In faba bean (Vicia faba) under drought conditions, inoculation with mycorrhiza was shown to enhance nodulation in comparison to non-mycorrhizal plants (Abdel-Fattah et al, 2002). Under drought stress, inoculation with G. mosseae caused an increase in P uptake by maize plants in comparison to an uninoculated plant (Abdelmoneim et al, 2014).…”

Drought is a critical factor limiting the productivity of legumes worldwide. Legumes can enter into a unique tripartite symbiotic relationship with root-nodulating bacteria of genera Rhizobium, Bradyrhizobium, or Sinorhizobium and colonization by arbuscular mycorrhizal fungi (AMF). Rhizobial symbiosis provides nitrogen necessary for growth. AMF symbiosis enhances uptake of diffusion-limited nutrients such as P, Zn, Cu, etc., and also water from the soil via plant-associated fungal hyphae. Rhizobial and AMF symbioses can act synergistically in promoting plant growth and fitness, resulting in overall yield benefits under drought stress. One of the approaches that rhizobia use to survive under stress is the accumulation of compatible solutes, or osmolytes, such as trehalose. Trehalose is a non-reducing disaccharide and an osmolyte reported to accumulate in a range of organisms. High accumulation of trehalose in bacteroids during nodulation protects cells and proteins from osmotic shock, desiccation, and heat under drought stress. Manipulation of trehalose cell concentrations has been directly correlated with stress response in plants and other organisms, including AMF. However, the role of this compound in the tripartite symbiotic relationship is not fully explored. This review describes the biological importance and the role of trehalose in the tripartite symbiosis between plants, rhizobia, and AMF. In particular, we review the physiological functions and the molecular investigations of trehalose carried out using omics-based approaches. This review will pave the way for future studies investigating possible metabolic engineering of this biomolecule for enhancing abiotic stress tolerance in plants.

Unequal understanding among tin mining stake holders on trade regulation often triggered social conflict and therefore it was suggested to build political will especially among national, provincial, and regencial/municipal government levels. One important effort to bring out political will is presenting an independent and scientific study on comparision between socio-economic and environmental impact of tin mining. Purposive sampling was conducted to inconventional miners at reserved forest at Lubuk Kelik hamlet, pepper farmers at Silip village, and rubber farmers at Bencah village. Tin mining changed soil properties and microclimate, reduced vegetation composition and structure, arbuscular mycorrhizal fungi, phosphate solubilizing microorganism, ants, and Collembola population. Land conversion increased and contributed up to 95% income. The welfare improvement, however, was apparent as the recovery cost was neglected by inconventional tin miners, and only pepper land conversion showed benefit. Inconventional tin mining regulation needs improvement in order to increase land use efficiency and recovery cost. Understanding on ecological balance of more people and for more sustainable social welfare should be improved as well.

“…Enhancing agronomic procedures and raising high-yielding salinity-tolerant cultivars could increase productivity per unit area, especially in saline media. Asrar and Elhindi, 2011;Kumar et al, 2010;Parádi et al, 2002;Abdel-Fattah et al, 2002) arbuscular mycorrhizal fungi are frequently more tolerant of environmental challenges and more competitive than non-mycorrhizal related plants. One of Bangladesh's most serious issues with the coastal districts is salinity.…”

Salinity stress can negatively impact the growth and productivity of young wheat seedlings, leading to diminished grain yield and quality. Poor salinity management can cause soil sodicity in farming soils, where sodium (Na) binds to negatively charged clay, causing clay swelling and dispersal, subsequently decreasing the crop yield. Thus, the use of salinity tolerant varieties can be a plausible solution. This article investigates the effects of salinity stress on the germination and early seedling growth of 15 wheat genotypes in Bangladesh. The seeds were exposed to four levels of salinity (0, 6, 9, and 12 dS/m) and various germination parameters were measured, such as water imbibition, germination rate, seedling tissue water content, and seedling vigour index. The results showed significant differences among the genotypes and the salinity levels for all the parameters. BARI Gom 25 was found to be the most tolerant genotype, followed by BARI Gom 24, BARI Gom 29, and Binagom-1. The article also discussed the implications of these findings for saline soil remediation and wheat production in coastal areas of Bangladesh
