“…The effect of heat stress treatment on TSP content was statistically significant (Table 1). Likewise, the TSP content of Trigonella plants was reduced 69.4% at 40°C comparing to control samples (Osman et al, 2020). Tokyol and Turhan (2019) found that the TSP content of green bean genotypes reduced and/or induced with heat stress.…”

“…In addition to enzymatic antioxidants, non-enzymatic antioxidants, especially AsA, known with its strong antioxidant capacity and low energy requirement for its biosynthesis, provides the initial support to plants against oxidative stress (Alayafi, 2020) caused by photosynthesis, aerobic metabolism and abiotic stresses such as heat stress (Kumar et al, 2011). Temperature increases to which plants are exposed causes alteration of membrane fluidity affects membrane functions such as disruption of photosynthesis and respiration (Raja et al, 2020), misfolding of proteins and accumulation of protein aggregates which create proteotoxic stress (Osman et al, 2020;Haider et al, 2021). Plants actuate the antioxidant defense system to relieve the injurious effects of oxidative stress (Chaudhry and Sidhu, 2022).…”

The effects of heat stress on malondialdehid (MDA) content, ascorbic acid (AsA), isoperoxidases, total soluble protein (TSP) and SDS-PAGE protein profiles of small reddish bean (Phaseolus vulgaris L. cv. Keklik) leaves were investigated. For this purpose, the collected leaf samples (preferably the third from the apex) were placed into pyrex tubes with caps closed and incubated in a water bath: after a 30-minutes habituation at 30ºC, to apply heat stress the leaves were subjected to 35, 40, 45, 50, 55 and 60°C with gradual increments every 30-minutes. According to the results, the MDA content increased with escalating temperatures, starting with 40°C. Although there was fluctuation, the AsA content generally decreased with high temperatures. Besides, TSP content decreased after 50°C. Moreover, three asidic and four basic isoperoxidase bands were identified. There was a marked difference at acidic isoperoxidase band intensities under 40 and 45°C heat treatment. Protein bands with molecu1ar weight of approximately 14.5-195 kDa were determined. In conclusion, especially 40°C is critical for small reddish bean plants, besides 40°C and above temperatures causes oxidative stress in small reddish bean plant. Additionally, isoperoxidases and proteins may be an effective mean on heat stress tolerance.

“…Heat stress has a negative effect on protein structure and activity (Hasanuzzaman et al, 2013). It is known that high temperatures cause denaturing proteins by causing misfolding (Haq et al, 2019;Osman et al, 2020). The protein content of Trigonella was significantly decreased by 27.8% at 35°C and 69.4% at 40°C respectively comparing to control samples (Osman et al, 2020).…”

Some cucurbit plants (Cucumis sativus L., Cucurbita pepo L., Cucumis melo L. and Citrillus lanatus L.) were used for investigating some physiological changes and protein patterns under heat stress in plants. Leaf samples were exposed tohigh temperatures as follows 35, 40, 45, 50, 55 and 60°C. Percentage of ion leakage, chlorophyll content, leaf relative water content (RWC) and loss of turgidity, total soluble protein (TSP) content and protein profiles were determined in leaf samples kept at each temperature stage for 30 minutes. Ion leakage was increased especially 55 and 60°C in all cucurbits parallel to the temperature increasement. Total chlorophyll content was decreased slightly in both cucumber cultivars, zucchini, in both melon cultivars and watermelon due to high temperatures. The RWC of cucurbits was decreased on the contrary of the loss of turgidity, which was parallel to the increment of temperatures. While the TSP content in cucumber was decreased with temperature increasement, it was not changed in zucchini and watermelon. In melon cultivars TSP was not noticeably changed until 55°C, but significantly decreased at 60°C. When the SDS-PAGE profiles of cucurbits were examined, many protein bands were observed with sizes ranging from 6.5 kDa to 211 kDa.
