Sporangium
Definition:
(n.) A spore case in the cryptogamous plants, as in ferns, etc.
Example Sentences:
(1) This "belt," usually first observed toward the center of the sporangium, developed without changing thickness or appearance over the surface of the forespore.
(2) It is proposed that simple, eucarpic, monocentric chytrids which discharge zoospores following dissolution of the sporangium wall evolved into multipapilliate species of Rhizophydium and 2 lines of evolution from these species are documented with examples.
(3) The cytoplasmic sporangium cleavage is brought about by the fusion of flagellar sheaths and cleavage vesicles.
(4) The mature resting sporangium (RS) wall of Coelomomyces dodgei (Chytridiomycetes; Blastocladiales) consists of three principal layers: (I) an outer pigmented layer (1.8-2.2 microns) that contains polysaccharide, (II) a middle electron translucent layer (1.3-1.6 microns) comparatively free of polysaccharide, and (III) an inner layer (125 nm) rich in polysaccharide that surrounds the meiospores.
(5) By inference, the sporulation division septum locus is distal to the ultimate normal cell division septum, i.e., proximal to the "old" pole of the B. megaterium sporangium.
(6) With the progress of spore encapsulation, the tyrocidine production migrated from the soluble fraction into the forespore, terminating with the separation of forespores from the sporangium membrane.
(7) Similarity of these bodies to sporangium-like structures is suggested.
(8) Using a transcriptional fusion of the spoIVC gene to the lacZ gene of Escherichia coli, we found that spoIVC expression was turned on at the third to fourth hour of sporulation (at about the developmental stage [IV] that its products are required in spore formation) and that this transcription was largely restricted to the mother cell chamber of the sporangium.
(9) However, a decrease in bacterial toxicity occurred with sporangium lysis.
(10) The transcriptional activity of the two genomes of the sporangium during spore formation was determined by pulse-labeling bacteria with 3H-uracil at different times of sporulation and preparing them for high resolution autoradiography.
