Summary: Metal oxide nanoparticles are critical tools for overcoming crop productivity challenges, boosting crop production and resistance to abiotic stresses such as drought. They enhance osmotic adaptation and crop water balance by mitigating drought-induced reactive oxygen species. The impacts of different forms, features, and dosages of MONPs on plant growth and development under drought stress are summarized and discussed in this review.

Summary: Salt stress is a major abiotic barrier to crop yield and profitability, particularly in arid and semi-arid regions. Plants have developed various mechanisms to tolerate salinity, including the synthesis and accumulation of osmoprotectants. A combination of physiological and molecular techniques is used in agricultural research to understand how plants adapt to salt stress at different levels.

Summary: Strigolactones (SLs), as novel phytohormones, play a crucial role in enhancing plant tolerance to abiotic stresses by responding to nutrient deficiency, drought, high temperature, and light stress. They assist in initiating physiological responses and mediating the interaction with soil microorganisms, attracting beneficial microorganisms and providing essential elements to roots. In addition to their role in stress resistance, SLs also affect photosynthesis, bridge other phytohormones, and induce metabolic compounds.

Summary: Phyto-hormones in plants are crucial for regulating crop growth and yield, especially under salt stress. Recent studies have highlighted the significant role of exogenous hormones, such as gibberellin (GA) and salicylic acid (SA), in regulating cotton's response to salt stress. However, a comprehensive understanding of the mechanisms by which these hormones regulate growth and yield under salt stress is still lacking.

Summary: Triclosan (TCS) is a widely distributed antibacterial agent, and its high concentration in sludge can cause physiological damage to plants. Little is known about the physiological and molecular mechanisms of TCS in plants. Research has shown that TCS treatment leads to decreased germination rate, root development, photosynthesis efficiency, and increased ROS accumulation in tobacco plants. Transcriptome analysis revealed differential gene expression mainly enriched in plant hormone signal transduction pathways in response to TCS stress. Transgenic tobacco overexpressing a salicylic acid binding protein gene exhibited enhanced antioxidant enzyme activities and TCS resistance, highlighting the important role of the SA signal pathway in TCS response in plants.

Summary: Citrus productivity in the Mediterranean basin has been declining due to climate change and high salinity levels in the aquifers. The rootstock has been found to play a crucial role in stress tolerance, but the scion also has an important impact. The study demonstrates that a versatile photosynthetic system, appropriate stomatal density, and modulation of genes encoding Cl- transporters are important for citrus tolerance to high salinity.
