“…During the vegetative growth phase, it manifests as reduced leaf expansion, plant height, and stem diameter, leading to weakened growth vigor. Additionally, it also affects the fruit setting rate and individual fruit quality during the reproductive growth phase, ultimately resulting in decreased yield and quality [3]. As a consequence, soil salinization has become a bottleneck factor in restricting the development of eggplant production.…”

Eggplant (Solanum melongena L.), a widely cultivated vegetable of the Solanaceae family, faces significant challenges in growth and yield due to soil salinization. This study aimed to investigate the functional role of the transcription factor SmMYB39 in salt stress tolerance in eggplant. This investigation was conducted through the utilization of bioinformatics analysis, quantitative real-time polymerase chain reaction (qRT-PCR), subcellular localization, validation of transcriptional activation activity, Virus-Induced Gene Silencing (VIGS), and protein interactome analysis. Bioinformatics analysis revealed that SmMYB39 has the closest relationship with SlMYB41, and its promoter contains multiple stress-responsive elements. qRT-PCR results demonstrated that SmMYB39 was significantly upregulated after 12 h of salt stress. Subcellular localization results indicated that the SmMYB39 protein is localized in the nucleus and exhibits transcriptional activation activity. Using VIGS, we observed that silencing of SmMYB39 led to reduced salt stress tolerance in eggplant. In addition, we have conducted research on the protein interactome of SmMYB39. In conclusion, our study demonstrates that SmMYB39 is a crucial transcription factor involved in salt stress response and has the potential to enhance salt tolerance in eggplant.

“…Biochar might reduce osmotic stress by adsorbing excess Na + from the soil [42]. Similarly, the addition of biochar resulted in a decrease in the uptake of Na+ and an increase in the uptake of K + with all irrigation treatments [25]. The LSD test was used to determine if there were significant differences between the columns.…”

“…Biochar could enhance soil properties, crop production, and water use efficiency with water scarcity by reducing the adverse impacts of salinity and drought stress [ 24 ]. According to Hannachi et al [ 25 ], biochar addition at 4.8 tons/ha enhanced the vegetative growth traits, the number of flowers, and fruit diameter. However, it did not compensate for the yield decrease or reduce the sodium ion content of fruits under salinity stress [ 26 ].…”

Enhancing saline water productivity in arid regions is essential for sustainable agriculture. Adding biochar can improve the quantity and quality of tomato yield under higher levels of salinity and lower levels of irrigation. The experiment aimed to evaluate the effects of biochar on enhancing tomato fruit quality and yield under salinity and drought stress. The experiment combines two treatments for irrigation water quality (0.9 and 2.3 dS m−1), four irrigation levels (40, 60, 80, and 100%) of crop evapotranspiration (ETc), and the addition of 5% of biochar to treated soil (BC5%) and untreated soil (BC0%). The results showed that the decrease in the water quality and irrigation levels negatively impacted the yield and properties of tomato fruit, while 5% of biochar application positively improved the yield. Adding biochar decreased the tomato yield by 29.33% and 42.51% under lower-saline-irrigation water than the control, negatively affecting the fruit’s physical parameters and mineral content. In contrast, adding biochar and irrigating with saline water at 60% of ETc improved the firmness and quality characteristics of the fruit by 56.60%, 67.19, 99.75, and 73.57% for vitamin C (VC), total titratable acidity (TA), total soluble solids (TSS), and total sugars (TS), respectively, compared to the control, and also reduced the sodium content of the fruits under all irrigation levels compared to untreated plants by biochar. Generally, biochar with saline water under deficit irrigation with 80 and 60% of ETc could be an excellent strategy to enhance the qualitative characteristics of tomato fruits and save approximately 20–40% of the applied water.

Soil salinization is a serious concern across the globe that is negatively affecting crop productivity. Recently, biochar received attention for mitigating the adverse impacts of salinity. Salinity stress induces osmotic, ionic, and oxidative damages that disturb physiological and biochemical functioning and nutrient and water uptake, leading to a reduction in plant growth and development. Biochar maintains the plant function by increasing nutrient and water uptake and reducing electrolyte leakage and lipid peroxidation. Biochar also protects the photosynthetic apparatus and improves antioxidant activity, gene expression, and synthesis of protein osmolytes and hormones that counter the toxic effect of salinity. Additionally, biochar also improves soil organic matter, microbial and enzymatic activities, and nutrient and water uptake and reduces the accumulation of toxic ions (Na + and Cl), mitigating the toxic effects of salinity on plants. Thus, it is interesting to understand the role of biochar against salinity, and in the present Review we have discussed the various mechanisms through which biochar can mitigate the adverse impacts of salinity. We have also identified the various research gaps that must be addressed in future study programs. Thus, we believe that this work will provide new suggestions on the use of biochar to mitigate salinity stress.
