Photosynthesis and fructose 2,6-bisphosphate content in water stressed wheat leaves
2000
Ramachandra Reddy, A.
Net photosynthetic rates, sucrose levels, fructose 2,6-biphosphate content and the related enzyme activities were investigated in control and water stressed leaves of Triticum aestivum L. var sonalica. Fructose 2,6-biphosphate accumulated in waterstressed plants and reduced leaf photosynthesis, sucrose content and the activities of fructose 1,6-biphosphate and sucrose phosphate synthase. C-incorporation into sucrose was drastically reduced in stressed plants. Fructose - 6-phosphate-2-kinase activity was extremely high in stressed plants while the activity of fructose 2,6-biphospate was low.
