Summary: The interaction between nitric oxide (NO) and carbon monoxide (CO) enhances heat resistance in wheat seedlings, with NO produced by nitrate reductase (NR) participating in signal transduction. The increase in NO stimulates the formation of reactive oxygen species (ROS), further enhancing the antioxidant effects of CO.

Summary: Abiotic stress caused by heavy metals has a negative impact on plant growth, especially in crop plants, which affects grain yield and sustainable food security. Excessive copper availability impairs plant growth and reproductive performance. Hydrogen peroxide plays a role in mitigating oxidative damage caused by biotic or abiotic stress, but its influence needs further quantification. This study investigated the effects of hydrogen peroxide on the growth, grain yield, and copper uptake of stressed wheat, and found that foliar application of hydrogen peroxide improved growth and yield traits under copper stress.

Summary: This study investigated changes in wheat resistance to wheat streak mosaic virus (WSMV) at normal and elevated temperatures and their effects on the emission of volatile organic compounds (VOCs) in wheat cultivars. The results showed that VOCs in the leaves of resistant (R) and susceptible (S) cultivars responded differently to WSMV and temperature changes. Several metabolic pathways and compounds were up-regulated in R plants, especially at an earlier time and at elevated temperatures. The lipoxygenase pathway played an important role in increasing vector attractiveness and tolerance to biotic and abiotic stresses. The results emphasize the importance of understanding the synchronized regulation of defense-related VOCs for plant resistance to viruses and heat stress.

Summary: A new sensing platform based on G-quadruplex-hemin DNAzyme (GQH) functionalized gold-coated nanopipettes was established. GQH was immobilized on the gold-coated nanopipette and acted as a catalyst for the reaction of H2O2 with ABTS to promote the conversion of ABTS to ABTS+ ions inside the nanopipette, allowing real-time monitoring of transmembrane ion current changes. The correlation between ion current and H2O2 concentration in a certain range enables the use of this immobilized nanopipette for hydrogen peroxide sensing.

Summary: Melatonin is a multifunctional bioregulator in both mammals and plants. This study investigated the effect of melatonin on the resistance of wheat and rye seedlings to high temperature and the functioning of cellular protection systems. The results showed that melatonin treatment reduced the inhibition of growth caused by high temperature in wheat seedlings, while it had a smaller effect on rye seedlings. Melatonin treatment also prevented oxidative stress in both wheat and rye seedlings under high temperature conditions.

Summary: Extreme temperatures, especially in recent decades, have had a significant impact on plants and are one of the most dangerous abiotic stress factors. This review analyzes the latest information on the mechanisms by which plant cells receive signals of hyperthermia, including the role of membrane fluidization, changes in calcium channels, and increased generation of reactive oxygen species. The significance of gasotransmitters (NO, H2S) and their interactions with other mediators in transmitting heat stress signals to the cell nucleus is separately summarized. The role of key transcription factors (HSF, MBF, NAC, and WRKY) in plant adaptation to high temperatures is analyzed. Modern ideas on the activation and functioning of the main protective systems that provide plant resistance to hyperthermia, such as heat shock protein synthesis, antioxidant and osmoprotective systems, are summarized. Examples of genetic improvement of heat resistance in plants through gene transformation in the control of these systems are given.

Summary: Polyamines are plant metabolites that play important roles in various physiological processes. Among them, the least studied polyamine, cadaverine, was found to have a protective effect on wheat seedlings under heat stress by increasing the activity of antioxidant enzymes. The resistance of seedlings to heat damage was enhanced by cadaverine treatment, which also led to an increase in hydrogen peroxide content and the activity of antioxidant enzymes in the roots.
