Two glycoside hydrolases decompose the sporangium matrix to release spores during sporangium dehiscence in Actinoplanes missouriensis [PDF]
The actinomycete Actinoplanes missouriensis grows as a substrate mycelium and forms terminal sporangia containing a few hundred spores surrounded by an unidentified matrix called the sporangium matrix.

Documenting the Sporangium Development of the Polypodiales Fern Pteris multifida
Reconstructing the development of sporangia in seed-free vascular plants provides crucial information about key processes enabling the production of spores that are important in the life cycle of these plants.

Involvement of a putative acyltransferase gene in sporangium formation in Actinoplanes missouriensis [PDF]
The actinomycete Actinoplanes missouriensis forms branched substrate mycelia during vegetative growth and produces terminal sporangia, each of which contains a few hundred spherical flagellated spores, from the substrate mycelia through short ...

Sporangium Exposure and Spore Release in the Peruvian Maidenhair Fern (Adiantum peruvianum, Pteridaceae). [PDF]
We investigated the different processes involved in spore liberation in the polypod fern Adiantum peruvianum (Pteridaceae). Sporangia are being produced on the undersides of so-called false indusia, which are situated at the abaxial surface of the ...

Phycomyces: Growth Responses of the Sporangium [PDF]
During the development of the sporangiophore of the fungus Phycomyces blakesleeanus there occurs a period of several hours when the sporangiophore does not elongate; instead, its "growth" is diverted into the formation of a sporangium at its top. This period of head formation is called stage II. Clearly, growth has not ceased but rather the geometry of

Involvement of an orphan response regulator of the two-component regulatory system in the formation of physiologically mature sporangia in Actinoplanes missouriensis [PDF]
The actinomycete Actinoplanes missouriensis forms terminal sporangia that contain dormant sporangiospores. Upon contact with water, sporangia release zoospores through a process called sporangium dehiscence.

A unique sigma/anti-sigma system in the actinomycete Actinoplanes missouriensis [PDF]
Bacteria of the genus Actinoplanes form sporangia that contain dormant sporangiospores which, upon contact with water, release motile spores (zoospores) through a process called sporangium dehiscence.

Development of Sporangium in Botrychium [PDF]
1. The sporogenous tissue develops from a single hypodermal archesporial cell. 2. As the successive sporogenous cells are formed, each retains its individuality throughout the development of the sporogenous tissue. 3. Divisions in the sporogenous tissue are simultaneous up to the mother-cell stage. 4.

The genera Mohria and Anemia (Anemiaceae: Pteridophyta) can be separated on both their sporangia and spores. In Mohria the capsule is globose with an apical annulus but in Anemia it is ovate-globose to cylindrical with a subapical annulus.
