Summary: This review aims to reveal the individual role and action mechanism of methyl salicylate in systemic acquired resistance, plant-plant communication, and various stress conditions in fruits and plants. Despite the similarities in action between methyl salicylate and salicylic acid, they have distinct functions in plants.

Summary: Balanced photosynthesis is crucial for plant survival and agricultural benefits. Drought stress disrupts photosynthetic efficiency, but chloroplast retrograde signaling and genetic imprints can help preserve photosynthetic capacity. Agronomic and genetic engineering approaches, along with isoprene regulation, offer potential solutions for rescuing photosynthetic apparatus during drought stress.

Summary: The study showed that exogenous silicon can significantly promote the growth of tomato plants under low-calcium conditions by protecting photosynthetic pigments, enhancing energy production, boosting Calvin cycle enzyme activity, and ensuring efficient photosynthesis. The method of silicon application affects its effectiveness, with foliar spraying alleviating photosynthetic inhibition and root application promoting root growth.

Summary: Hydroponic experiments were conducted to investigate the effects of prolonged sulfate limitation and Cd exposure on Arabidopsis thaliana and Nicotiana tabacum. Both species showed adverse effects on morphology, photosynthetic and biochemical parameters, and nutritional status under low sulfate treatments and Cd stress. The responses to low sulfate supply, Cd exposure, or a combination of both factors were species-specific, and Cd exposure had opposing effects on the levels of certain elements in the roots.

Summary: This study found that external boron application can reduce cadmium uptake in wheat and alleviate the toxicity of cadmium. Boron treatment decreased cadmium concentrations and malondialdehyde levels, while increasing antioxidant enzyme activity. The metabolites affected by boron application were mainly related to linoleic acid metabolism, galactose metabolism, sphingolipid metabolism, glycolysis/gluconeogenesis, and propanoate metabolism in diabetic complications.

Summary: This study investigated the effects of different concentrations of salicylic acid (SA) on the growth and cadmium (Cd) content of lettuce under Cd stress. The results showed that 100-200 mg/L SA significantly improved the plant height and biomass of lettuce under Cd stress. SA at concentrations of 200 mg/L and 500 mg/L reduced the activities of peroxidase and superoxide dismutase caused by Cd stress, and down-regulated the expression of genes related to Cd uptake, leading to a reduction in Cd content in lettuce shoots.

Summary: This study investigated the role of salicylic acid (SA) and potassium (K) in enhancing the resilience of quinoa against the combined stress of salinity and cadmium (Cd). The results showed that the addition of SA and K helped quinoa plants adapt better to the stress, reducing plant biomass and accumulation of Na and Cd in plant tissues.

Summary: Water deficit is a significant stress that affects crop growth and production. This study found that salicylic acid (SA) plays a crucial role in regulating the photosynthetic adaptability of maize seedlings under water deficit by protecting the chloroplast integrity and repairing the damaged photosystem II reaction center. SA treatment enhanced chlorophyll content and activity of key enzymes related to photosynthesis, thereby improving the water-deficit tolerance in maize seedlings.

Summary: Research isolated 36 salt-tolerant plant growth-promoting bacteria (ST-PGPB) from sodic soil in India, with 13 strains showing better growth properties in high salt concentrations. Inoculation with Bacillus pumilus strain JPVS11 improved rice growth performance, chlorophyll content, and soil enzyme activities, indicating its potential as a beneficial bacterium for mitigating salinity effects in rice.

Summary: The use of biochar can improve soil and plant enzymatic activities, enhance nutrient cycling and accumulation, and increase the utilization of inorganic fertilizer and crop growth. Combining biochar with nitrogen fertilizer can increase soil enzymatic activities and improve the activity of nitrogen metabolism-related enzymes in plants. The combination of 30 t ha(-1) biochar and 450 kg ha(-1) nitrogen fertilizer can promote rapeseed growth and yield, while 15 t ha(-1) biochar with 225 kg ha(-1) nitrogen fertilizer can improve nitrogen use efficiency.
