In Arabidopsis , overexpression of these isoforms also provides improved tolerance against salinity and helps maintain lower levels of MG compared to wild type plants
The absorbance at 360 nm of a reaction mixture containing 20 mM Tris-HCL Ph 7.6, 1 mM EDTA, 10 mM ammonium sulphate, 0.2 mM dithiothreitol (Sigma), 0.2 mM MESG (Berry & associates), 1.25U PNP (Sigma), 4 M small GTPase and 0.5 mM GTP (Cytoskeleton Inc.)
At the whole leaf level o thef Arabidopsis wildtype, increase in photo-protective anthocyanins was visible in plants grown at 300 mol m 2 s 1 , which was more pronounced, but also accompanied by small necrotic lesions at leaf edges at 700 mol m 2 s 1 , and intensified even more at 1500 mol m 2 s 1 , while the photosynthesis-associated pigments (chlorophyll and carotenoids) were reduced (Heyneke et al

This increased availability of glutathione may contribute to a more pronounced skin-brightening effect
