“…Chilling reduces the rate of photosynthesis and dry matter accumulation, which would ultimately result in grain yield loss for rice (Allen & Ort, 2001; Luo, 2011; Shi, Guo, Cheng, et al, 2022; Thakur et al, 2010). Our results showed that chilling treatments impaired photosynthesis, restrained the source availability and eventually led to grain yield reduction due to the carbon limitation.…”

“…Rice plants were cultivated in plastic pots, and the plant density was 3 plants per pot (22 cm diameter × 30 cm height). Water and fertilizer management practices were drawn from Shi, Guo, Cheng, et al (2022). In each pot, 2 g ammonium sulphate, 1 g potassium sulphate and 1 g diammonium phosphate were applied as the basal fertilizer.…”

“…Transcriptome analysis revealed that low nitrogen stress reduced the expression levels of genes related to the apple antenna system, light absorption, and electron transfer (Wen et al, 2022). A reduction in photosynthesis ultimately leads to a decrease in biomass production and yield (Shi et al, 2022). Glycolysis, the pentose phosphate pathway (PPP), and the tricarboxylic acid (TCA) cycle are the major metabolic pathways in plants and are influenced by nitrogen supply, providing energy and carbon skeletons for other metabolic pathways.…”

“…An inflated source/sink ratio may result in a waste of carbon assimilation, and a slow output of photosynthetic products from leaves will feed back to inhibit source assimilation activity [ 4 , 5 ]. On the other hand, a low source/sink ratio may lead to the consumption of assimilate from source organs and a decline in the photosynthetic area and yield [ 6 ]. Therefore, a reasonable source/sink ratio is crucial for achieving high crop yields.…”
