The activation energy and activation volume of the spectral blue shift subsequent to protochlorophyllide phototransformation (called Shibata shift in intact leaves) were studied in prolamellar body (PLB) and prothylakoid-(PT)-enriched membrane fracti

SUMMARY To understand the phenomenon by which infection of seed-transmitted Barley stripe mosaic virus (BSMV) alters membrane structures and inhibits protochlorophyllide biosynthesis of dark-grown barley (Hordeum vulgare L.) plants, we analysed the p

The proteome of the etioplast inner membranes (EPIM) of dark-grown wheat leaves (Triticum aestivum L.) was mapped as an essential part of studies on plastid differentiation. Proteins were separated by two-dimensional gel electrophoresis and analysed

The aurea and yellow-green-2 (yg-2) mutants of tomato (Solanum lycopersicum) are unable to synthesize the phytochrome chromophore from heme resulting in a block of this branch of the tetrapyrrole pathway. We have previously shown that these mutants a

The effects of modulated ADP/ATP and NADPH/NADP+ ratios, and of protein kinase inhibitors, on the in vitro reformation of phototransformable protochlorophyllide, i.e. the aggregated ternary complexes between NADPH, protochlorophyllide, and NADPH-prot

The spectral blue-shift of chlorophyllide (Chlide) in flash irradiated isolated prolamellar bodies (PLBs) of dark-grown wheat ( Triticum aestivum ) was analysed. The fluorescence emission at −196°C of Chlide varied depending on the composition of
Protochlorophyllide transformations and chlorophyll accumulation in epicotyls of pea (Pisum sativum)
Publikováno v:
Physiologia Plantarum. 96:706-713
Low-temperature fluorescence emission spectra of epicotyls of 6.5-day-old dark-grown seedlings of pea (Pisum sativum L.) showed the dominance of short-wavelength protoch lorophyllide forms with emission maxima at 629 and 636 nm, respectively. The pre

Protochlorophyllide a was isolated from dark-grown barley (Hordeum vulgare L.) seedlings. The circular dichroism spectrum was identical with that of protochlorophyll a prepared from chlorophyll a b...

A preparation of prolamellar bodies from wheat etioplasts was used as a source for NADPH-protochlorophyllide oxidoreductase (pchlide reductase). The enzyme was solubilized with Triton X-100 after reduction of the endogenous photoconvertible protochlo

Etioplast development and protochlorophyllide (Pchlide) accumulation was studied in wheat seedlings (Triticum aestivum L. cv. Walde, Weibull) grown in darkness on gibberellic acid (GA 3 ), gabaculine (3-amino-2,3-dihydrobenzoic acid), or on a combina
