“…They function as signaling molecules during stress conditions and play a crucial role in reducing toxicity by decreasing ROS levels. This ability has led to the growing interest in utilizing strigolactones as potential plant growth regulators for managing salt stress in agriculture [14,58]. Furthermore, microorganisms, particularly plant growth-promoting rhizobacteria (PGPR), have shown promising results in alleviating abiotic stresses, including salt stress.…”

Salt stress has detrimental effects on wheat plants at several physiological, biochemical, and molecular levels. This stress leads to suppressed growth, reduced grain yield, and poor quality of harvested grains. However, two approaches have shown promise for improving wheat salt tolerance: using a synthetic strigolactone analog called GR24 and applying plant growth-promoting rhizobacteria (PGPR). GR24 plays a vital role in regulating plant growth and development and in defense against various stresses. Conversely, PGPR are beneficial bacteria that colonize the rhizosphere of plants and promote their growth through multiple mechanisms. In our study, we investigated the effects of salinity on the growth and yield traits of two different wheat cultivars and explored the combined role of PGPR and GR24 in mitigating the impact of salt stress. We created three different salinity levels using NaCl in pots (original, 5 dS m−1, and 10 dS m−1) and inoculated wheat seeds with a salt-tolerant Bacillus velezensis UTB96 strain. In addition, we applied 10 μM GR24 via foliar application during the pollination stage. Our observations showed that salt stress negatively affected wheat’s growth, yield, and phytochemical properties compared to the control. However, both single and combined applications of PGPR and GR24 mitigated the adverse effects of salinity. The combined treatment had a more substantial impact than either alone in inducing and improving biochemical and ionic characteristics. These included decreasing Na+ content in both leaves and roots, and EL, H2O2, and MDA content in leaves while increasing K+ content in both leaves and roots, growth and yield-related traits, RWC, chlorophyll pigments, total protein, soluble sugar, starch, proline, GB, and antioxidant enzyme activity (APX, POX, and CAT) of leaves. In conclusion, integrating PGPR and GR24 can efficiently induce salt tolerance and improve plant growth under stressed conditions. This combined approach has the potential for broad applicability in supporting plant growth in the presence of salt stress.

“…The authors emphasize the importance of these compounds in alleviating the negative impacts of nutrient deficiency, high salinity, drought, extreme temperatures, and toxic elements on plant growth and development. They [23] elucidate these hormones' pivotal role in optimizing nutrient uptake efficiency in situations of limited availability (Table 1). According to their explanation, strigolactones activate the symbiotic relationship between plants and arbuscular mycorrhizal fungi (AMF), thereby facilitating the absorption of nutrients from the soil.…”

Understanding the mechanisms of nutrient transfer between AMF and host plants is essential for enhancing our knowledge of plant nutrition and improving agricultural practices. Transporters are protein substances that enable the movement of nutritional elements between the host plant and AMF. They ensure even and adequate distribution and uptake of micronutrients, phosphorus, and nitrogen. Apart from transporters, AMF also have a crucial role in the distribution of nutrients within the host plants. These beneficial microbes establish an intricate system of hyphae that spreads in soil, assimilating limited nutrients that would otherwise be inaccessible to the host plant. These fungal networks augment the plant's ability to obtain nourishment, particularly in environments where some elements are limited. The mechanisms underlying the transporter network involved in nutrient exchange between AMF and host plants remain to be fully deciphered. Examining the connections of this network can bring to light the coordination between incongruent transporters and the entire process of nutrient interchange. Future studies should prioritize investigating the particular molecules and genes engaged in nutrient exchange to understand this essential mutual relationship better. Furthermore, assessing the impact of environmental factors on AMF associations can help devise strategies to optimize nutrient absorption in agricultural systems. By manipulating ecological factors such as soil nutrients or pH levels, it may be possible to increase the efficiency of nutrient transfer, thus improving plant growth and productivity.
