Microbodies in conifer needle mesophyll
Protoplasma, 1974Microbodies are described in the mesophyll tissue of several conifer species. Cytochemical staining ofPinus strobus andPicea mariana with 3,3′ diaminobenzidine indicated the presence of catalase in microbodies. In older tissue microbody staining was variable with peroxidative activity occurring in mesophyll cell walls and the cytoplasm.

Occurrence of microbodies in chloromonadophycean algae
Archives of Microbiology, 1974Microbody-like organelles occur in the cytoplasm of two chloromonadophycean algae,Vacuolaria virescens Cienkowsky andGonyostomum semen Diesing. Microbodies ofVacuolaria andGonyostomum have a granular matrix which lacks a crystalloid core; they are often present in close association with elements of the endoplasmic reticulum.

Microbody of Methanol‐Grown Yeasts [PDF]
European Journal of Biochemistry, 1975 Profuse appearance of microbodies was observed in the cells of methanol‐utilizing yeasts in connection with the enhanced catalase activity. These microbodies were isolated successfully by means of sucrose gradient centrifugation from the methanol‐grown cells of Kloeckera sp. no. 2201.

Microbody proliferation and segregation cycle in the single-microbody alga Cyanidioschyzon merolae
Planta, 1999The proliferation cycle of the microbody was studied in the primitive red alga Cyanidioschyzon merolae, which contains one microbody per cell. Cells were synchronized with a dark/light cycle, and the morphology of the microbody and its interaction with other organelles were observed three-dimensionally by fluorescence microscopy, transmission electron ...

Zeitschrift für Pflanzenphysiologie, 1984
Summary Microbody fractions not contaminated by mitochondria, plastids, or protein bodies were isolated from sunflower cotyledons during the transition of the cotyledonary microbody population from glyoxysomal to leaf peroxisomal function. In these microbody fractions, specific enzyme activities could be determined based on microbody protein content.

Microbodies in Different Algae
1984Microbodies with distinctive morphological features in electron micrographs were first described in 1954. Since then they have been seen, not only in many animal and plant tissues but also in protozoa, fungi and algae, indicating that their occurrence is ubiquitous (Hruban and Rechcigl 1969, Gerhardt 1978).

Biogenesis of Plant Microbodies
1987The development of microbodies involves an import of proteins across the organelle membrane. Details of this process were studied with glyoxysomal malate dehydrogenase from watermelon cotyledons. The enzyme was synthesized as a cytosolic, higher–molecular–weight precursor (41 kD).

Microbodies (Peroxisomes) in Sebaceous Glands
Proceedings, annual meeting, Electron Microscopy Society of America, 1971The cells of the supracaudal gland of guinea pig have abundant cytoplasm, round and ovoid mitochondria, abundant free ribosomes, a few rough cisternae, abundant vesicular reticulum, complex agglomerates of tubular reticulum, a few residual bodies and a few multivesicular bodies. Golgi complex is small. Electron lucid lipid droplets are numerous.

Existence of DNA in yeast microbodies
Proceedings, annual meeting, Electron Microscopy Society of America, 1978We have found that microbodies appeared profusely together with a remarkable increase in catalase activity in normal alkane-grown cells of hydrocarbon-utilizing Candida yeasts, and that the microbodies multiplied by division in these cells. These features of Candida yeasts seem to provide a useful model system for studies on the biogenesis of the ...

The Biosynthesis of Microbodies (Peroxisomes, Glyoxysomes)
1982Publisher Summary This chapter discusses the biosynthesis of microbodies, such as peroxisomes and glyoxysomes. With respect to biochemical properties, microbodies are characterized by at least one oxidase reducing O 2 to H 2 O 2 . This production of peroxide and its employment by catalase-catalyzed reactions led to the term “peroxisome.” Ribosomes ...
