5.3.1.6 | additional information | construction of T-DNA knockout mutants of the RPI2 gene, which encodes the cytosolic ribose-5-phosphate isomerase. Knockout of the RPI2 gene does not significantly change the total RPI activity in the mutant plants, but knockout of RPI2 interferes with chloroplast structure and decreases chloroplast photosynthetic capacity. Rpi2 mutants accumulate less starch in the leaves and flower significantly later than wild-type when grown under short-day conditions, and rpi2 mutants display premature cell death in the leaves when grown at an above-normal temperature of 26°C, phenotypes, detailed overview | Arabidopsis thaliana |
