Impact of two different types of heat stress on chloroplast movement and fluorescence signal of tobacco leaves

Popis výsledku v původním jazyce

Although the chloroplast movement can be strongly affected by ambient temperature, the information about chloroplast movement especially related to high temperatures is scarce. For detailed investigation of the effects of heat stress (HS) on tobacco leaves (Nicotiana tabacum L. cv. Samsun), we used two different HS treatments in dark with wide range of elevated temperatures (25-45 °C). The leaf segments were either linearly heated in water bath at heating rate of 2 °C/min from room temperature up to maximal temperature (Tm) and then linearly cooled down to 25 °C or incubated for 5 min in water bath at the same Tm followed by 5 min incubation at 25 °C (T-jump). The changes in light-induced chloroplast movement caused by the HS pretreatment were detectedafter the particular heating regime at 25 °C using a method of time-dependent collimated transmittance (CT) and compared with the chlorophyll O-J-I-P fluorescence rise (FLR) measurements.
