Laccase from Sycamore Maple (Acer pseudoplatanus) Polymerizes Monolignols.
Current understanding of the final oxidative steps leading to lignin deposition in trees and other higher plants is limited with respect to what enzymes are involved, where they are localized, how they are transported, and what factors regulate them. With the use of cell suspension cultures of sycamore maple (Acer pseudoplatanus), an in-depth study of laccase, one of the oxidative enzymes possi...
متن کاملAcer pseudoplAtAnus L., Acer plAtAnoides L. and BetulA pendulA Roth. as bioindicatoRs of uRban poLLution in sofia
Acer pseudoplatanus L., Acer platanoides L. and Betula pendula Roth. have been studied under the urban pollution in Sofia during 3 years period. The aim of the study was, by statistical multifactorial analysis, to assess the value changes in morphological parameters of species under air pollution and potential for species usage as bioindicators in observed regions. The statistical analysis incl...
متن کاملRapid Degradation of Abnormal Proteins in Vacuoles from Acer pseudoplatanus L. Cells.
In Acer pseudoplatanus cells, the proteins synthesized in the presence of an amino acid analog ([(14)C]p-fluorophenylalanine), were degraded more rapidly than normal ones ([(14)C]phenylalanine as precursor). The degradation of an important part of these abnormal proteins occurred inside the vacuoles. The degradation process was not apparently associated to a specific proteolytic system but was ...
متن کاملProtein Phosphorylation in Amyloplasts Isolated from Suspension-Cultured Cells of Sycamore (Acer pseudoplatanus L.).
Highly purified amyloplasts were isolated from cultured cells of sycamore (Acer pseudoplatanus L.). Incubation of amyloplasts with [gamma-(32)P]-ATP resulted in the labeling of more than ten polypeptides. Pulsechase experiments showed the reversibility of the process with some but not all of the polypeptides. The phosphorylation reaction of one polypeptide, M(r) 100, was shown to be calcium dep...
متن کاملThe Fine Structure and Development of the Companion Cell of the Phloem of Acer Pseudoplatanus
At maturity the companion cell of the phloem of the sycamore Acer pseudoplatanus has a large nucleus, simple plastids closely sheathed with rough endoplasmic reticulum, and numerous mitochondria. The cytoplasm contains numerous ribosomes, resulting in a very electron-opaque cytoplasm after permanganate fixation. Bodies similar to the spherosomes of Frey-Wyssling et al. (4) are collected in clus...
