ABSTRACT Leaf colour mutants play an important role in understanding chlorophyll metabolism and photosynthesis. In this study, we characterised a temperature‐sensitive yellow leaf cotton mutant. Genome re‐sequencing comparison identified 10.327 Kb deletion on the D12 chromosome (D12:670726‐681053) The region contains two annotated genes, GH_D12G0047 GH_D12G0048 . Investigations integrating gene mapping, comparative transcriptome analysis, annotation, virus‐induced silencing complementation, found of or GhSCY2D , crucial constituent Sec2 complex essential for function chloroplasts, being responsible phenotype. mutant had disrupted chloroplast structure hindered synthesis when temperature was below 28°C but regained normal green at 32°C. By analysing data hormonal level changes under conditions 25°C 32°C, it that jasmonic acid signalling pathway GhSCY2 work concert to maintain structural integrity chloroplasts. outcomes study reveal indispensable sustaining homoeostasis, providing new insights into regulation paving way advancement high photosynthetic efficiency breeding strategies.

Photorespiration causes a substantial decrease in crop yield because of mitochondrial decarboxylation. Alternative pathways (APs) have been designed to relocate the decarboxylation step or even fix additional carbon. To improve success transferring those engineered APs from model species crops, we must understand how they will interact with metabolism and plant physiology affects their performance. Here, used multiple mathematical modeling techniques analyze compare existing AP designs. We show that carbon-fixing are most promising candidates replace native photorespiration major species. Our results demonstrate different metabolic routes use increase which can profit them. anticipate our guide design new help ones.

The bioengineering of photorespiration has emerged as a key target for improving photosynthesis and crop yield. In our previous study, two photorespiratory bypasses, GOC GCGT, were successfully established in rice, the transgenic plants exhibited increased However, reduced seed-setting rates observed both GCGT rice. To overcome this bottleneck, we introduced bypass into potato, potato is vegetatively reproduced without need pollination, unlike After was tested field experiments at different locations China with contrasting climates. Consequently, yield per plant by 21.3%-69.2% potatoes under normal growth conditions enhanced 12.9%-29.9% adverse environments. acquired more stable increase than Moreover, advantages high light, noticed earlier further verified study through various because obviously higher grown northern area solar radiation those south relatively lower radiation. Mechanistic analyses indicated that while suppressed, much fewer photosynthates accumulated potatoes. These results demonstrate increases stably well show promising prospects practical application yields, particularly high-light conditions.
