“…To meet the global food production demand, crop yields of most staple crops must increase by over 60–110% in the next 30 years [ 28 ]. At the same time, atmospheric CO 2 has been envisaged to reach 550 ppm in 2050 [ 29 ], and this is usually accompanied by rising terrestrial air temperature, all in the name of global warming [ 30 ].…”

Photosynthetic carbon converted to sucrose is vital for plant growth. Sucrose acts as a signaling molecule and a primary energy source that coordinates the source and sink development. Alteration in source–sink balance halts the physiological and developmental processes of plants, since plant growth is mostly triggered when the primary assimilates in the source leaf balance with the metabolic needs of the heterotrophic sinks. To measure up with the sink organ’s metabolic needs, the improvement of photosynthetic carbon to synthesis sucrose, its remobilization, and utilization at the sink level becomes imperative. However, environmental cues that influence sucrose balance within these plant organs, limiting positive yield prospects, have also been a rising issue over the past few decades. Thus, this review discusses strategies to improve photosynthetic carbon assimilation, the pathways actively involved in the transport of sucrose from source to sink organs, and their utilization at the sink organ. We further emphasize the impact of various environmental cues on sucrose transport and utilization, and the strategic yield improvement approaches under such conditions.

“…Photosynthesis is the basis of plant yield in addition to being the most sensitive physiological process under high temperature stress (Ashraf & Harris, 2013). High temperature stress has a significant effect on photosynthesis (Baslam et al., 2020). At high temperature, plants must maintain a high photosynthetic rate to ensure survival or growth.…”

Global warming increases seawater temperature, causing high temperature stress to marine organisms, including algae. This study aimed to explore the global proteomic response of Sargassum fusiforme under high temperature stress. Sargassum fusiforme seedlings were cultured in natural seawater for 24 hr and subjected to different temperatures (22°C, control group; 27°C and 32°C, high temperature stress group) for 1, 3, 5 and 7 days. Changes in their membrane lipid peroxidation after high temperature stress were investigated. Proteomic changes in the air bladders of S. fusiforme were analysed using isobaric tags for relative and absolute quantification, along with liquid chromatography-tandem mass spectrometry. Data were analysed using bioinformatics methods. Results showed that high temperature stress destroyed the cell membrane of the air bladders. Further, 28 and 53 differentially expressed proteins (DEPs) were found in the 27°C and 32°C treatment groups respectively. These DEPs were mainly involved in glycolysis, single-organism catabolism, purine nucleoside diphosphate metabolism and carbohydrate catabolism. In addition, DEPs were significantly enriched in 10 pathways, such as glycolytic process, biosynthesis of antibiotics, ribosome, biosynthesis of secondary metabolites and biosynthesis of amino acids. Proteomics analyses indicated that proteins associated with synthesis, folding, degradation, photosynthesis and energy and carbohydrate metabolism are differentially expressed under high temperature stress and normal conditions.

“…Lights regulate the expression of many genes, including chloroplast biogenesis, chloroplast gene expression, and photosynthesis-associated processes, such as chloroplast movements [ 166 , 167 ]. There exist more than 40 TFs that act downstream of photoreceptor genes in Arabidopsis [ 168 ]. The TFs regulating starch biosynthesis have been also identified in rice [ 169 , 170 , 171 , 172 , 173 , 174 ], maize [ 175 , 176 , 177 , 178 ], barley [ 179 ], cassava [ 180 , 181 ], Panicum virgatum [ 182 ], sweet potato [ 183 ], and Arabidopsis [ 184 , 185 , 186 , 187 ].…”

“…C and N metabolic engineering aims to analyze and modify metabolic pathways to achieve some objectives related to, among others, improving yields, adapting to stresses, and facilitating the efficient production of industrially relevant compounds (See also [ 168 , 377 , 378 ]). Few significant improvements in C and N assimilation been achieved [ 379 , 380 ], due to the synchronous activation of a series of metabolic pathways that might be needed to influence assimilation.…”

C and N are the most important essential elements constituting organic compounds in plants. The shoots and roots depend on each other by exchanging C and N through the xylem and phloem transport systems. Complex mechanisms regulate C and N metabolism to optimize plant growth, agricultural crop production, and maintenance of the agroecosystem. In this paper, we cover the recent advances in understanding C and N metabolism, regulation, and transport in plants, as well as their underlying molecular mechanisms. Special emphasis is given to the mechanisms of starch metabolism in plastids and the changes in responses to environmental stress that were previously overlooked, since these changes provide an essential store of C that fuels plant metabolism and growth. We present general insights into the system biology approaches that have expanded our understanding of core biological questions related to C and N metabolism. Finally, this review synthesizes recent advances in our understanding of the trade-off concept that links C and N status to the plant’s response to microorganisms.
