Effect of heat stress on polyamine metabolism in proline-over-producing tobacco plants

Popis výsledku v původním jazyce

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 1-pyrroline-5-carboxylate synthetase (P5CSF129A) and in the corresponding wild-type. In the initial phases of heat stress (after 2 h at 40 ?C), the accumulation of proline increased in the wild type but slightly decreased in the transformants. The response to heat stress in proline-over-producing tobacco plants involved a transient increase in the levels of free and conjugated putrescine (Put) and in the levels of free spermidine (Spd), norspermidine (N-Spd) and spermine (Spm) after a 2-h lag phase, which correlated with stimulation of the activity of the corresponding biosynthetic enzymes. Diamine oxidase (DAO) activity increased in both plant genotypes, most significantly in th
