Microsporogenesis and microgametogenesis of two species, Cardiospermum grandiflorum Sw. and Urvillea chacoensis Hunz. (Sapindaceae, Paullinieae), were studied using light and transmission electron microscopy. Both species are monoecious, with staminate and hermaphrodite, although functionally pistillate, flowers.

Microsporogenesis and Microgametogenesis of Male‐Sterile Mutant ms1 in Alfalfa
Crop Science, 2013ABSTRACTThe use of male sterile lines is one of the ways to reduce the selfing rates and thus maximize heterosis in alfalfa (Medicago sativa L.). A spontaneous, stable male sterile mutant ms1 has been derived from M. sativa ‘Graze401’. In this paper, the microsporogenesis and microgametogenesis have been examined in ms1 and wild‐type plants under light

Morphological study of microgametogenesis of Leucocytozoon simondi
Journal of Ultrastructure Research, 1970The 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.

Scanning Electron Microscopy of Eimeria tenella Microgametogenesis and Fertilization
The Journal of Parasitology, 1977Microgametes of Eimeria tenella were observed in cecal tissue from infected chicks killed six days after inoculation with oocysts. Development from the microgamont stage to maturity was followed. We observed three commonly found, but distinctly different, stages in developing microgametes while they were still associated with microgamonts. In the first,

High voltage electron microscopy on microgametogenesis of Haemoproteus columbae
Zeitschrift f�r Zellforschung und mikroskopische Anatomie, 1974The 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 ...

Fine structure of leucocytozoon caulleryi during microgametogenesis and fertilization
Zentralblatt für Bakteriologie, Mikrobiologie und Hygiene. 1. Abt. Originale. A, Medizinische Mikrobiologie, Infektionskrankheiten und Parasitologie, 1984The 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.

Electron microscope studies of microgametogenesis in coccidia and related groups
Zeitschrift f�r Parasitenkunde, 1972The 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.

Mitochondrial atp6 transcript editing during microgametogenesis in male-sterile sorghum
Current Genetics, 2001A marked reduction of mitochondrial atp6 transcript-editing capability in sorghum anthers and pollen has been invoked as a factor in the loss of viability of male gametophytes in lines carrying the IS1112C male-sterile cytoplasm. We initiated a systematic examination of transcript editing of sorghum atp6 during microgametogenesis, from microspores ...

The Fine Structure of Microgametogenesis in Haemoproteus columbae Kruse*
The Journal of Protozoology, 1968SYNOPSIS. The structural changes leading to the formation of motile microgametes from a single immobile intracellular gametocyte have been examiued in the electron microscope. After pigeon blood infected with Haemoproteus columbae was exposed to the air at room temperature for a few minutes axonemes appeared in the parasite's cytoplasm and the ...
