“…It has been reported that sucrose content decreases with the increase in temperature ( Loka and Oosterhuis, 2010 ). Studies have shown proteomic changes in different tissues like leaves and anthers of plants at high temperatures, as well as differential expression of proteins related to various physiological processes, such as carbohydrate metabolism ( Das et al., 2015 ; Kumar et al., 2022 ; Zhou et al, 2017 ). The balance between sucrose synthesis and catabolism in leaves is mediated by influencing the activity of sucrose synthase (SS) and sucrose phosphate synthase (SPS), two key enzymes that also control the biosynthesis of carbon into starch ( Stitt and Zeeman, 2012 ) However, few researchers have studied the effect of night temperature on the biosynthesis of leaf sucrose.…”

IntroductionSoybean is sensitive to light and temperature. Under the background of global asymmetric climate warming.MethodsThe increase of night temperature may have an important impact on soybean yield. In this study, three varieties with different level of protein were planted under 18°C and 28°C night temperatures for investigating the effects of high night temperatures on soybean yield formation and the dynamic changes of non-structural carbohydrates (NSC) during the seed filling period (R5-R7).Results and discussionThe results indicated that high night temperatures resulted in smaller seed size, lower seed weight, and a reduced number of effective pods and seeds per plant, and thus, a significant reduction in yield per plant. Analysis of the seed composition variations showed carbohydrates were more substantially affected by high night temperature than protein and oil. We observed “carbon hunger” caused by high night temperature increased photosynthesis and sucrose accumulation in the leaves during the early stage of high night temperature treatment. With elongated treated time, the excessive carbon consumption led to the decrease of sucrose accumulation in soybean seeds. Transcriptome analysis of leaves after 7 days of treatment showed that the expression of most sucrose synthase and sucrose phosphatase genes decreased significantly under the high night temperature. Which could be another important reason for the decrease of sucrose. These findings provided a theoretical basis for enhancing the tolerance of soybean to high night temperature.

“…Recently, 14 common QTLs were identified among the 42 and 43 QTLs underlying the rice response to biotic or heat constraints respectively. Meta-expression analysis of the 1265 genes underlying the 14 QTLs showed that 24 genes were involved in calcium signaling, supporting its importance in plant response to both constraints ( Kumar et al., 2022 ). However, common QTLs identified with constraints applied individually do not necessarily imply that they would also be detected when applying these constraints in combination.…”

“…Rice is the staple food for a whole continent and sustainability of rice cultivation is indispensable. The meta-analysis of genomic regions involved in heat and drought stress of rice by Kumar et al (2022) sheds light in the genetic makeup of this trait and thus opens avenues for improvement. The global demand for high-quality plantbased protein increases steadily.…”

Humanity is facing enormous challenges in the years to come: sustainability of agriculture and sustainability of our supply with food, feed and renewable materials are neither granted nor free. Especially, but not only, in the Global South, a sustainable increase in agricultural productivity and a steady reduction of avoidable losses are undoubtedly key issues that need to be addressed.In order to pinpoint the most pressing challenges and strategies to achieve targets, the United Nations have formulated the Sustainable Development Goals (https:// sdgs. un. org/ goals). Among these, several are directly or indirectly addressing agriculture, food supply and sustainability, most notably SDG2 (zero hunger), SDG12 (responsible consumption and production), SDG13 (climate action) and SDG15 (life on land).
