“…High temperatures shorten the growth period by accelerating the growth of leaves and preventing them from obtaining the reserve energy they need to grow (Peer et al, 2020). Plants show varying degrees of sensitivity to high temperature, which depends on the severity, scope and timing of stress (Peer et al, 2020). For example, the cells of P. yezoensis seedlings are divided into horizontal divisions at the early stage of germination, and the thallus cells are arranged in a straight line; the cells start to divide vertically upon reaching 7–10 cells (Tian et al, 2020).…”

Pyropia haitanensis is one of the main cultivated macroalgae in China. In recent years, the cultivation of P. haitanensis conchospores in seawater is conducted in advance to obtain earlier harvest. However, the high seawater temperature may exert negative impacts on the algae. Seven temperature conditions (25, 26, 27, 28, 29, 30 and 31°C) were set in the culture of P. haitanensis to investigate the effects of temperature on the conchospore germination and early seedling development of P. haitanensis. The results showed that conchospore germination rate decreased with the increase in temperature. The temperatures of 25 and 26°C were suitable for P. haitanensis conchospore germination. Higher temperature (27°C) promoted conchospore germination on the 1st and 2nd days but decreased the germination considerably on the 3rd day. The conchospore mortality rate reached 89% after culture at high temperature (31°C) for 4 days. Additionally, the development of conchospore seedlings was normal, the total number of cells increased, and the survival rate was high (53%–90%) in the range of 25–29°C. At 25°C, the absolute growth rate of seedlings was as high as 302%. However, the development slowed down and the absolute growth rate decreased with the increase in temperature. At 30 and 31°C, seedling development was abnormal or even ceased, the survival rate was as low as 20% (30°C) and 11% (31°C), and the absolute growth rates were negative under the two conditions. The mortality of seedling was remarkably higher at 31°C than at other temperatures and gradually increased with the increase in temperature (25–31°C). And, the potential mechanisms underlying high temperature damages were analysed. Therefore, the temperature range suitable for the seedling collection and cultivation of P. haitanensis conchospore is 25–29°C.

“…Many studies have demonstrated the negative impact of heat stress on the physiology of crop growth and development. Peer et al (2020) extensively reviewed heat stress impacts on various physiological aspects, including water relations, membrane stability, respiration, and photosynthesis and indicated that they are negatively impacted while plant hormones, growth regulators, and metabolites are attuned at both the primary and secondary level. Plants respond to these modulations through the increased synthesis of heat shock proteins, reduced reactive oxygen species (ROS) production, membrane stability maintenance, osmoprotectant agglomeration, mitogen-activated protein kinase (MAPK) and calcium-dependent protein kinase (CDPK) cascade induction, antioxidant generation, and chaperone signaling, which eventually culminates in thermotolerance.…”

“…1). There has been considerable progress in understanding heat stress physiology from the whole plant to cellular level (Peer et al 2020), advancing in phenomics to capture heat stress responses (Basavaraj and Rane 2020), deciphering epigenetic regulation at the molecular level (Shanker et al 2020) and identifying promising candidates genes, such as glyoxalase (Garai et al 2020), to address heat stress induced damage in crops. This special issue collated recent advances and current knowledge on heat stress responses in crops to provide a framework for designing objectives and hypotheses for further research in our quest to develop crop varieties that can sustain productivity under future hotter environments.…”

The predicted increase in global mean temperature and its variability is a significant challenge for sustainable crop productivity under current and future climates. Research on understanding heat stress responses, identifying physiological processes, developing phenotyping protocols and unraveling molecular pathways that can help breed heat stress resilient crops is prominent in the crop science community. Research teams and laboratories contributing to this special issue title 'Heat Stress on Crop Growth and Development' have consolidated information on multiple dimensions of heat stress. The collection of reviews and research papers provides an excellent platform for developing future research objectives and is a valuable reference for students and researchers working on the heat stress response in crops.

“…Hence, understanding the complexities of heat tolerance mechanisms is a key to manipulate tolerance in plants (Milner, 2020). The plant responses to heat stress vary depending on the plant and even the tissue or organ within the same plant affected (Peer et al, 2020). The devastating effects of heat stress on plant metabolism includes, disrupting cellular homeostasis and uncoupling major physiological and biochemical processes.…”

The effects of high temperatures on melon cvs. Miranda and Poli, watermelon cv. Crimson Tide and zucchini cv. Asma leaves. The leaves obtained from plants were subjected to 35, 40, 45, 50, 55 and 60°C temperatures with gradual increments every 30-minutes. Samples, obtained at each treatment, were analyzed for ascorbic acid content, NADP(H) oxidase, catalase, gluthatione reductase, peroxidases activities and isoperoxidase patterns. The ascorbic acid content slightly increased parallel to temperature increment in zucchini but did not change in watermelon and in both melon cultivars. Melon cv. Poli exhibited comparatively less oxidative damage than cv. Miranda with a lower NAD(P)H oxidase activity. Heat stress induced NAD(P)H activity in watermelon and zucchini comparing to control plants. Results revealed that antioxidative enzyme activities were increased generally up to 50°C then decreased gradually in melon cultivars. Besides cv. Poli generally had higher enzyme activities than cv. Miranda. The activity of catalaes become prominent in watermelon while the activity of ascorbate peroxidase become prominent in zucchini. Acidic isoperoxidase bands with different relative mobility values were found in all species. Besides, basic isoperoxidase band could not be determined in both melon cultivars and watermelon while a basic isoperoxidase band was found in zucchini.
