Summary: Tomato is highly sensitive to temperature changes and climate change-induced global warming poses a major threat to its production. In this study, the photosynthetic capability of iaa9-3 and iaa9-5 mutants under heat-stress conditions was examined. It was found that these mutants maintained their photosynthetic capability even after 14 days of heat treatment, indicating the beneficial effect of the SlIAA9 mutation on plant adaptation to heat stress.

Summary: This study found that under high temperature conditions, the emission of leaf monoterpenes significantly increased in the INRA809 grape variety, while there was no significant change in the SMA130 variety. Additionally, when leaf temperature exceeded 30 degrees Celsius, INRA809 maintained higher photosynthetic rates and stomatal conductance values. This suggests that monoterpenes emission plays a significant role in heat tolerance of grapes under high temperatures.

Summary: Climate change poses a threat to global coffee production, emphasizing the importance of studying heat tolerance. This study found that acclimation to different light conditions does not affect photosynthetic heat tolerance in coffee varieties, but it is associated with leaf size and stomatal density. C. canephora exhibits higher heat tolerance than C. arabica.

Summary: Climate change increases the severity and duration of heatwaves, which has a significant impact on plants. The current method of determining heat limits for plants is based on a 30-minute test, which fails to consider the effect of heat-dose (intensity x exposure-duration) on heat limits. This study measured heat limits for dysfunction and damage in alpine species after exposure to various heat-doses, and found that exposure-duration had a significant impact on these heat limits. The findings suggest the need for a more comprehensive approach to assessing plants' heat tolerance.

Summary: This study investigates the transcriptome profiling of two Bacillus subtilis strains isolated from distinct environments and reveals variations in gene expression related to antibiotic synthesis. The two strains exhibit similar effects on Arabidopsis seedlings but differ in their ability to enhance drought, heat, and copper stress tolerance. Additionally, treatment with the strains activates distinct genes associated with the ABA signaling pathway.

Summary: The study investigated the impact of short-term and longer heat stress on the photosynthesis and secondary metabolites in an important invasive species, Heracleum sosnowskyi. Results showed that high temperature induced physiological responses such as accumulation of proline, anthocyanins, and furanocoumarins, along with lipid peroxidation damage. Further research could focus on suppressing these metabolites to control the spread of this invasive species.

Summary: The afterglow photosynthetic luminescence, known as AG emission, is a long-lived chlorophyll fluorescence emitted from PSII. It can be recorded by TL technique and used to study the energetic state and metabolism processes of the chloroplast, as well as the impact of various stress conditions on photosynthetic materials.
