“…Western blot analysis using the monoclonal antibody (P25) generated against pea phyA (Cordonnier et al, 1986) was performed as described by Heyer and Gatz (1992b). For the western blot analysis shown in Figure 4B a different set of antibodies was used.…”

We have generated transgenic potato plants (Solanum fuberosum) containing the potato phytochrome protein encoded by the PHYA gene cDNA (phyA) in sense or antisense orientation under the control of the 35s cauliflower mosaic virus promoter. Plants with increased and decreased phyA levels were analyzed. When grown under white light, development and growth of sprouts and plants were barely distinguishable from wild type. Under continuous far-red light, stem extension, leaf expansion, and hook opening of sprouts were accelerated in phyA overexpressors and delayed in antisense plants. Sprouts with reduced phyA levels were less sensitive to red light with regard to stem extension and expression of the small subunit genes for ribulose bisphosphate carboxylase. Under low red 1ight:far-red light ratios, increased phyA levels reduced the stem extension component of the shade-avoidance response, whereas decreased levels led to an increase in the response.

“…In algae, phytochrome detected in some fresh-water and marine chlorophyta (Taylor & Bonner 1967;Cordonnier et al 1986), in red algae (López-Figueroa & Niell 1988;López-Figueroa et al 1989), in brown algae (López-Figueroa et al 1989), in cyanobacteria (Scheibe 1972;Björn & Björn 1976, 1980, and in phyco-and photobionts of lichens (Czeczuga et al 2008). Phytochrome also was detected in Treobuxia sp.…”

The effect of light quality on the photosynthetic pigments as chromatic adaptation in 8 species of lichens were examined. The chlorophylls, carotenoids in 5 species with green algae as phycobionts (Cladonia mitis, Hypogymnia physodes, H. tubulosa var. tubulosa and subtilis, Flavoparmelia caperata, Xanthoria parietina) and the chlorophyll a, carotenoids and phycobiliprotein pigments in 3 species with cyanobacteria as photobionts (Peltigera canina, P. polydactyla, P. rufescens) were determined. The total content of photosynthetic pigments was calculated according to the formule and particular pigments were determined by means CC, TLC, HPLC and IEC chromatography. The total content of the photosynthetic pigments (chlorophylls, carotenoids) in the thalli was highest in red light (genus Peltigera), yellow light (Xanthoria parietina), green light (Cladonia mitis) and at blue light (Flavoparmelia caperata and both species of Hypogymnia). The biggest content of the biliprotein pigments at red and blue lights was observed. The concentration of C-phycocyanin increased at red light, whereas C-phycoerythrin at green light. In Trebouxia phycobiont of Hypogymnia and Nostoc photobiont of Peltigera species the presence of the phytochromes was observed.

“…Cross-reacting proteins had been detected with monoclonal antibodies directed against pea phytochrome in the green algae Mougeotia, Mesotaenium and Chlamydomonas (Cordonnier et al, 1986). More recently, phytochrome-like proteins were detected in Dunaliella and Chlorella (Ruyters et al, 1991) and in several Rhodophyceae, Phaeophyceae and Chlorophyceae using monoclonal antibodies raised against phytochrome from etiolated Avena saliva and Zea mays (L6pez-Figueroa et al, 1989a).…”
