Ultra-weak photon emission as a non-invasive tool for the measurement of oxidative stress induced by UVA radiation in Arabidopsis thaliana

Popis výsledku v původním jazyce

All living organisms emit ultra-weak photon emission as a result of oxidative processes caused by the physical or chemical stress factors. In the present study, the effect of oxidative stress induced by the exposure of the plant model Arabidopsis thaliana to ultraviolet A (UVA) radiation was studied using ultra-weak photon emission. When Arabidopsis plants and leaves were exposed to UVA radiation, two kinetically distinguished phases in the ultra-weak photon emission decay were observed: the fast decayphase (?1 = 0.805+-0.024 min) and slow decay phase (?2 = 4.321+-0.166 min). The spectral analysis of the UVA radiation-induced ultra-weak photon emission showed that the photon emission during the fast decay phase is from both blue-green and red regionsof the spectrum, whereas the photon emission during the slow decay phases is solely from the blue-green region of the spectrum. These observations reveal that triplet excited carbonyls contribute to ultra-weak photon emission during both
