The effect of heat stress on the accumulation of proline and on the level of polyamines (PAs) in tobacco plants was investigated. Responses to heat stress were compared in the upper and lower leaves and roots of tobacco plants that constitutively over-express a modified gene for the proline biosynthetic enzyme Δ1-pyrroline-5-carboxylate synthetase (P5CSF129A) and in the corresponding wild-type. In the initial phases of heat stress (after 2h at 40°C), the accumulation of proline increased in the… CONTINUE READING
