Arabidopsis exocyst subunit SEC6 is involved in cell plate formation during Microgametogenesis
Biochemical and Biophysical Research Communications, 2022Cytokinesis during pollen mitosis I is critical for cell division and differentiation in the male gametophyte development, but the vesicle trafficking mechanisms in this process are largely unknown. Exocyst is an octameric tethering complex which plays multiple important roles in plant cell vesicle trafficking.

Microsporogenesis, microgametogenesis, and pollen morphology of Ambrosia artemisiifolia L. in China
Plant Systematics and Evolution, 2011Ambrosia artemisiifolia L. from Ambrosia of the Heliantheae of the Asteraceae family is a recognized harmful weed worldwide and one of the major invasive foreign plants in China. In this study, we investigated its reproductive features, focusing on its microsporogenesis, microgametogenesis, and pollen morphology.

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 ...

MOLECULAR GENETIC ANALYSES OF MICROSPOROGENESIS AND MICROGAMETOGENESIS IN FLOWERING PLANTS
Annual Review of Plant Biology, 2005In flowering plants, male reproductive development requires the formation of the stamen, including the differentiation of anther tissues. Within the anther, male meiosis produces microspores, which further develop into pollen grains, relying on both sporophytic and gametophytic gene functions.

Ultrastructural observations of microgametogenesis in Eimeria bakuensis (Syn. E. ovina) of sheep
Parasitology Research, 1988The ultrastructure of microgametogenesis of Eimeria bakuensis was studied in the intestinal epithelium of an experimentally infected sheep. During development the nuclei became situated peripherally in the microgamont. Nuclear chromatin condensed into peripheral, dense portions that became the nuclei of the microgametes.

Fine structural changes associated with microgametogenesis of Eimeria acervulina in chickens
Zeitschrift f�r Parasitenkunde, 1973The fine structure of the changes occurring during microgametogenesis and of the microgametes of Eimeria acervulina was studied in experimentally infected chickens. Early microgametocytes had relatively electron-transparent nuclei with few, scattered, dense masses. Micropores were seen at the surface of these microgametocytes. Intranuclear microtubules

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.

In the present study, microsporogenesis, microgametogenesis and pollen wall ontogeny in Campsis radicans (L.) Seem. were studied from sporogenous cell stage to mature pollen using transmission electron microscopy. To observe the ultrastructural changes that occur in sporogenous cells, microspores and pollen through progressive developmental stages ...

We have investigated the sequential stages of microgametogenesis by electron microscopy, to determine the basis of maternal inheritance of plastids in Epilobium. The development of both the vegetative and generative cells has been followed using a semi-artificial growth system for pollen tubes.
