“…Both elevated day‐time temperature alone and elevated day‐ and night‐time temperatures at grain filling have been long shown to affect rice starch composition and cooking properties. However, elevated NTAT alone was recently proved to significantly affect rice grain qualities both in the field and in controlled environmental growth conditions .…”

Stressful environments can alter starch biosynthesis in cereal endosperm. The aim of this review is to carefully examine how starch functional properties are altered when plants encounter environmental parameters outside of the normal range. This is important because while growers and processors require grain yield stability and product uniformity this will be challenging in an era of variable weather patterns. Being able to predict the general physico‐chemical nature of the starch as a result of growth status is a step towards the “precise” agriculture required for the 21st century. Variations in soil moisture and nutrient availability, ambient temperature, and atmospheric composition were all shown to affect starch functionality. Elevated temperature led to the most significant changes in both tropical and temperate cereals and amylose content was the most sensitive parameter under various environmental conditions. Genotypic variation appears to be a primary contributor for the response of cereal starches to environmental stress. Nonetheless, while a large amount of data from single controlled environmental stress experiment is currently available, comparably little is known about whether similar results would be achieved in multifactorial and large‐scale settings. The challenges in terms of the need for more detailed experimental descriptions to lessen the study‐to‐study discrepancies of data and to enhance their interpretability were also discussed.

High temperatures during rice grain ripening reduced yield and grain quality. The proportion of milky white grains was 43.6 % at 30°C but only 6.5 % at 25°C. Grain filling was initially faster at 30°C and finished earlier, and the final dry matter content was less, than at 25°C. High temperature strongly suppressed the expression of the sucrose transporter gene OsSUT1 and starch synthesisrelated genes SuSy2, AGPS2b, BEIIb and Granule-bound starch synthase in grains during early grain filling; the transcription levels of OsSUT1 at 14 days after flowering (DAF) were about 60 % lower in grains, flag leaf blade, flag leaf sheath and first leaf sheath. These facts are possibly involved in the earlier termination of grain filling at 21 DAF, following the rapid rise of grain dry weight from 0 to 7 DAF, due to possible reduction in assimilate supply via OsSUT1 under the high temperature. When panicles were partly clipped, the resultant increase in assimilate supply to the remaining grains significantly upregulated the expression of OsSUT1 and the starch synthesis-related genes at 14 DAF, which consequently accelerated starch accumulation in the grains and ultimately increased the grain weight of remaining grains at 30°C. These results indicate that high temperature during grain filling reduces grain yield and quality by changing the expression of OsSUT1 and starch synthase-related genes, resulting in earlier ripening due to hastened or premature assimilate supply to grains.

“…The rice plant's translocation system may affect the occurrence of BBWG. Tanaka et al (2009) observed earlier degradation of the nucellar epidermis under high temperatures in a heat-sensitive cultivar. Nitrogen application at the panicle formation stage increased the cross-sectional area of large vascular bundles (Nitta et al, 2000).…”
