“…In the presence of acetate, photosynthesis is less important for algal growth than in photoautotrophic conditions without acetate. Photosynthesis is one of the most heat sensitive functions in plants (Sharkey, 2005; Sharkey and Zhang, 2010) and is also the major source of ROS when photosynthetic activity is compromised by heat (Pospíšil, 2016; Qin-Di et al , 2021; Niemeyer et al , 2021). Although moderate high temperature of 35°C did not affect thylakoid structures or PSII activities significantly, the increased non-photochemical quenching (NPQ, photoprotection pathway) (Rochaix, 2014; Erickson et al , 2015) in 35°C-treated Chlamydomonas cells still suggested non-optimal or compromised photosynthesis at 35°C (Zhang et al , 2022 a ).…”

“…Carbon metabolism and sugar availability were shown to be essential for heat tolerance in Arabidopsis (Olas et al , 2021). Without sufficient carbon supply from source tissues (e.g., leaves), long-term moderate high temperatures may result in significant loss of plant yield (Li et al , 2015; Qin-Di et al , 2021). Arabidopsis seedlings treated with 5-day heat at 35°C had reduced growth and viability (Song et al , 2021).…”

High temperatures impair plant/algal growth and reduce food/biofuel production, but the underlying mechanisms remain elusive. The unicellular green alga Chlamydomonas reinhardtii is a superior model to study heat responses in photosynthetic cells due to its fast growth rate, many similarities in cellular processes to land plants, simple and sequenced genome, and ample genetic, genomic, and high-throughput tools. The interaction of heat responses with the availability of organic carbon sources is important for the algal biofuel/bioproduct industry but understudied. We cultivated Chlamydomonas wild-type cultures under highly controlled conditions in photobioreactors at control of 25°C, moderate high temperature of 35°C, or acute high temperature of 40°C with and without constant organic carbon supply (acetate) for 1- or 4-days. Our results showed that moderate high temperature was beneficial to algal growth with constant acetate supply but detrimental without it. The overlooked and dynamic effects of 35°C can be explained by induced carbon metabolisms, including acetate uptake/assimilation, glyoxylate cycle, gluconeogenesis pathways, and glycolysis. Acute high temperature at 40°C for more than 2 days was lethal to algal cultures even with constant acetate supply. Our research provides insights to understand algal heat responses and help improve thermotolerance in photosynthetic cells.

“…Rice ( Oryza sativa L.) is a major food crop cultivated in countries around the world, especially in Asia, and feeds more than 50% of the global population. Rising temperature due to global warming has a serious impact on rice production, and the damage may continue to rise in the future, particularly for Asian rice ( Qin-Di et al., 2021 ). Growing rice above its optimal growth temperature of 5°C results in a corresponding thermal response profile at the cellular and metabolic levels to maintain its own survival and growth ( Barnabás et al., 2008 ).…”

“…Growing rice above its optimal growth temperature of 5°C results in a corresponding thermal response profile at the cellular and metabolic levels to maintain its own survival and growth ( Barnabás et al., 2008 ). Heat stress is an essential environmental factor limiting rice growth and reproduction, causing different damage to different development stages of rice, and it will suffer from different degrees of heat stress from germination to seedling, anthesis, grain filling, and grain maturation stages ( Qin-Di et al., 2021 ). It has been reported that rice yield decreases by 3.2% for every 1°C increasing in global temperature ( Zhao et al., 2017 ).…”

High temperature is one of the main constraints affecting plant growth and development. It has been reported that abscisic acid (ABA) synthesis gene 9-cis-epoxycarotenoid dioxygenase (NCED) positively regulates plant resistance to salt, cold, and drought stresses. However, little is known about the function of the NCED gene in heat tolerance of rice. Here, we found that OsNCED1 was a heat stress inducible gene. Rice seedlings overexpressing OsNCED1 showed enhanced heat tolerance with more abundant ABA content, whereas the knockout mutant osnced1 accumulated less ABA and showed more sensitive to heat stress. Under heat stress, increased expression of OsNCED1 could reduce membrane damage and reactive oxygen species (ROS) level of plants, and elevate the activity of antioxidant enzymes. Moreover, real time-quantitative PCR (RT-qPCR) analysis showed that overexpression of OsNCED1 significantly activated the expression of genes involved in antioxidant enzymes, ABA signaling pathway, heat response, and defense. Together, our results indicate that OsNCED1 positively regulates heat tolerance of rice seedling by raising endogenous ABA contents, which leads to the improved antioxidant capacity and activated expression of heat and ABA related genes.
