Description:

Dark-grown seedlings of Pinus mugo Turra and Pinus sylvestris L. accumulate chlorophyll (Chl) and its precursor protochlorophyllide (Pchlide). Pchlide reduction is a key regulatory step in Chl biosynthesis. In the dark, Pchlide is reduced by light-independent Pchlide oxidoreductase (DPOR) encoded by three plastid genes chlL, chlN, and chlB (chlLNB). To investigate the differences in chlLNB gene expressions, we compared the dark-grown and 24-h illuminated seedlings of P. mugo and P. sylvestris. Expression of these genes was found constitutive in all analyzed samples. We report light-independent accumulation of important proteins involved in Chl biosynthesis (glutamyl-tRNA reductase) and photosystem formation (D1 and LHCI). Chl and Pchlide content and plastid ultrastructure studies were also performed. and K. Breznenová ... [et al.]
