Sporogenesis of a myxosporidan with motile spores

Cell and Tissue Research, 1979
Three types of cells comprise each Fabespora vermicola sporoblast: valvogenic (VAV), capsulogenic (CAP), and germinative (GEM). Walls, polar caps, and sutures are the main assemblages produced by the VAV cells. The unique polar cap organelle extends over the aperture region of the polar capsule component of the CAP cell.

Sporogenesis in Streptomyces melanochromogenes

Archives of Microbiology, 1978
The mode of spore differentiation in a strain of Streptomyces melanochromogenes was followed by analysis of ultrathin sections of sporulating aerial hyphae at various stages of sporogenesis. A special accent was laid on the formation of the sporulation septum and its alterations in the course of spore delimitation and separation.

Role of glutamate in the sporogenesis of Bacillus cereus

Journal of Bacteriology, 1977
Bacillus cereus T, sporulating in a chemically defined medium under optimum conditions, requires substrate quantities of glutamate during the first 4 h of sporogenesis. Seventy percent of the glutamate utilized was catabolized to CO2 during this period, with the remaining glutamate carbon assimilated into various spore constituents, principally protein

‘Endogenous Factor’ in Sporogenesis in Bacteria

Nature, 1963
EXTENSIVE investigations on the morphological changes during sporogenesis have afforded valuable information about this phenomenon1. The initiation of eporulation can be better understood if the metabolic events during the transition from a vegetative cell to its sporulating phase are known. Several attempts have been made to investigate the physiology

In vitro sporogenesis in a fern

Zeitschrift für Pflanzenphysiologie, 1972
Summary In vitro developed plants of Ceratopteris thalictroides, obtained from gametophytes, developed sporangia and functional spores on a simple nutrient medium. Fertility was beset with senescence.

Sporogenesis and gametogenesis of some Boraginaceae

Feddes Repertorium, 1992
AbstractEmbryological details pertaining to the development and structure of anther and ovule, sporogenesis, gametogenesis and gametophytes of 9 species of 7 genera belonging to Boraginaceae are described. Anther is tetrasporangiate with ‘Dicotyledonous type’ of wall development.

Sporogenesis in Reboulia hemisphaerica

Botanical Gazette, 1926
1. The premeiotic protoplast shrinks away from its angular sporogenous walls. Within the space created it secretes a special external membrane that functions as the wall of the spore mother cell. 2. A marked contraction of the nuclear network is preliminary to the reduction division.
