“…5 ). At a biochemical level, intraspecific variation in rice shows that maintained or increased expression of sucrose transporters in leaves, stems, and grains is related to heat tolerance ( Miyazaki et al , 2013 ; Phan et al , 2013 ; Zhang et al , 2018 ; Yaliang et al , 2020 ), particularly for transporters thought to be involved in phloem loading and apoplastic sucrose retrieval along the transport pathway ( Scofield et al , 2007 ; Julius et al , 2017 ). These findings suggest that sucrose transporters are promising targets to develop heat-resilient crop cultivars.…”

“…By catalysing sucrose degradation in sinks, they increase the amount of sucrose being unloaded from the phloem into these sinks. Increased or maintained expression and/or activity of invertases and sucrose synthases in reproductive sinks has been linked to heat tolerance in several crop species including rice, tomato, and chickpea ( Pressman et al , 2006 ; Li et al , 2012 ; Kaushal et al , 2013 ; Phan et al , 2013 ; Li et al , 2015 ; Bahuguna et al , 2017 ; Rezaul et al , 2019 ; Yaliang et al , 2020 ). With photosynthetic improvements to heat stress, the enzymes involved in sucrose transport and metabolism may become increasingly important for ensuring increased photosynthates reach vegetative and reproductive sinks.…”

As global land surface temperature continues to rise and heat wave events increase in frequency, duration and/or intensity, our key food and fuel cropping systems will likely face increased heat-related stress. A large volume of literature exists on exploring measured and modelled impacts of rising temperature on crop photosynthesis, from enzymatic responses within the leaf up to larger ecosystem scale responses that reflect seasonal and inter-annual crop responses to heat. This review discusses (i) how crop photosynthesis changes with temperature at the enzymatic scale within the leaf, (ii) how stomata and plant transport systems are affected by temperature, (iii) what features make a plant susceptible or tolerant to elevated temperature and heat stress, and (iv) how these temperature and heat effects compound at the ecosystem scale to affect crop yields. Throughout the review, we identify current advancements and future research trajectories that are needed to make our cropping systems more resilient to rising temperature and heat stress, which are both projected to occur due to current global fossil fuel emissions.

“…Furthermore, a large amount of sugar is introduced into the panicle during the ripening stage of rice, and the sugar signaling process is closely associated with the ripening process of rice grains [ 23 ]. High-temperature stress is one of the major environmental stresses that hinder grain development and growth by affecting sugar migration, which directly affects the quality and yield of seeds [ 24 ]. Not only high-temperature but also various abiotic stresses induce a common physiological response in the sugar/energy signaling system, thus indicating that an analysis of the sugar/energy signaling system and an analysis of the acting genes can play a vital role in the development of high-temperature-stress-tolerant rice varieties [ 25 , 26 ].…”

Background Recent temperature increases due to rapid climate change have negatively affected rice yield and grain quality. Particularly, high temperatures during right after the flowering stage reduce spikelet fertility, while interfering with sugar energy transport, and cause severe damage to grain quality by forming chalkiness grains. The effect of high-temperature on spikelet fertility and grain quality during grain filling stage was evaluated using a double haploid line derived from another culture of F1 by crossing Cheongcheong and Nagdong cultivars. Quantitative trait locus (QTL) mapping identifies candidate genes significantly associated with spikelet fertility and grain quality at high temperatures. Results Our analysis screened OsSFq3 that contributes to spikelet fertility and grain quality at high-temperature. OsSFq3 was fine-mapped in the region RM15749-RM15689 on chromosome 3, wherein four candidate genes related to the synthesis and decomposition of amylose, a starch component, were predicted. Four major candidate genes, including OsSFq3, and 10 different genes involved in the synthesis and decomposition of amylose and amylopectin, which are starch constituents, together with relative expression levels were analyzed. OsSFq3 was highly expressed during the initial stage of high-temperature treatment. It exhibited high homology with FLOURY ENDOSPERM 6 in Gramineae plants and is therefore expected to function similarly. Conclusion The QTL, major candidate genes, and OsSFq3 identified herein could be effectively used in breeding rice varieties to improve grain quality, while tolerating high temperatures, to cope with climate changes. Furthermore, linked markers can aid in marker-assisted selection of high-quality and -yield rice varieties tolerant to high temperatures.
