Ultrastructural study on dynamics of plastids and mitochondria during microgametogenesis in watermelon

Micron, 2012
Dynamics of plastids and mitochondria during microgametogenesis in watermelon were examined by means of transmission electron microscopy. Plastids are present as proplastids in the microspore and as amyloplasts in the vegetative cell of the bicellular pollen grain, whereas the generative cell is completely devoid of plastids, suggesting that microspore

Ultrastructure of microsporogenesis and microgametogenesis in Brachypodium distachyon

Protoplasma, 2015
Brachypodium distachyon has emerged as a model system for forage grass and cereal grain species. Here, we report B. distachyon pollen development at the ultrastructural level. The process of microsporogenesis and microgametogenesis in B. distachyon follows the typical angiosperm pollen development sequence.

High voltage electron microscopy on microgametogenesis of Haemoproteus columbae

Cell and Tissue Research, 1974
The microgametogenesis of Haemoproteus columbae was investigated by high voltage and conventional electron microscopy and the results were compared. The features of microgametogenesis which have become clear by high voltage electron microscopy include the distribution and arrangement of axonemes in the microgametocyte and the budding process and ...

Morphological study of microgametogenesis of Leucocytozoon simondi

Journal of Ultrastructure Research, 1970
The fine structure of the microgametocytes and microgametogenesis of Leucocytozoon simondi , a parasite of ducks and geese, was studied and compared to those of the related genus Plasmodia . The morphology of the microgametocyte of L. simondi is identical to that of avian malarial parasites.

Fine structural study of the microgametogenesis of Eimeria auburnensis

Zeitschrift f�r Parasitenkunde, 1969
The microgametogenesis of Eimeria auburnensis from experimentally infected calves killed 16 to 18 days after inoculation was investigated with the electron microscope. Early microgametocytes had nuclei with compact nucleoli and relatively few electron-dense masses.

Electron microscope studies of microgametogenesis in coccidia and related groups

Zeitschrift f�r Parasitenkunde, 1972
The fine structure of the microgamonts and microgametes of coccidia and related groups was investigated and is herein described and diagrammatically depicted. Particular attention is given to the developmental processes during the differentiation of the microgametes. The species included in the study are: Eimeria perforans, E. maxima, E.

The action of metabolic inhibitors on microgametogenesis in Plasmodium yoelii nigeriensis

Zeitschrift f�r Parasitenkunde, 1977
Mature gametocytes of Plasmodium yoelii nigeriensis were incubated in vitro with a variety of antibiotics whose activities were directed against DNA, RNA, protein and microtubule assembly. Following incubation for periods between 5 and 90 min, exflagellation was induced and the degree of inhibition produced by each drug was assayed microscopically. The

Fine structure of leucocytozoon caulleryi during microgametogenesis and fertilization

Zentralblatt für Bakteriologie, Mikrobiologie und Hygiene. 1. Abt. Originale. A, Medizinische Mikrobiologie, Infektionskrankheiten und Parasitologie, 1984
The fine structure of microgametogenesis and fertilization in Leucocytozoon caulleryi was studied. When the peripheral blood of chickens containing mature gametocytes was withdrawn or ingested by Culicoides arakawae , differentiation of the microgametocytes began immediately.
