1. Morfologia, anatomia e histoquímica de Noteroclada confluens Taylor ex Hook.Wilson (Pelliaceae, Marchantiophyta) / Morphology, anatomy and histochemistry of Noteroclada confluens Taylor ex Hook. & Wilson (Pelliaceae, Marchantiophyta)
Noteroclada confluens Taylor ex Hook. & Wilson é uma hepática de aparência folhosa, pertencente à família Pelliaceae (Marchantiophyta). Ocorre predominantemente em regiões montanhosas, declives e locais próximos à córregos, em solos argilosos. O presente estudo teve por objetivo descrever a morfologia, anatomia e histoquímica das estruturas do game

2. Embriologia de Miconia albicans (Sw.) Triana (Melastomataceae), especie agamospermica / Embriology of Miconia albicans (Sw.) (Melastomataceae), agamospermous species
Miconia albicans (Melastomataceae) is a species with diplosporic obligate agamospermy and no pollen viability in ?Cerrado? and Atlantic Forest vegetations. The sterility of pollen grains wasn?t restricted to one developmental stage and the major abnormality of the cells from pre-anthesis flower anthers was the deformation of the reproductive cell wall, mainl

3. RADIOSENSITIVITY OF SEVERAL DEHYDROGENASES AND TRANSAMINASES DURING SPOROGENESIS OF BACILLUS SUBTILIS1
Rowley, D. B. (Syracuse University, Syracuse, N.Y.), and H. R. Newcomb. Radiosensitivity of several dehydrogenases and transaminases during sporogenesis of Bacillus subtilis. J. Bacteriol. 87:701–709. 1964.—Cells of Bacillus subtilis grown in a chemically defined medium for 17 hr, subsequently washed, and transferred to a phosphate solution containing Ca

4. Macromolecular Synthesis During Microcycle Sporogenesis of Bacillus cereus T
Microcycle sporogenesis induced in Bacillus cereus T by phosphate limitation occurs over a narrow range of phosphate to spore inoculum ratios. Sufficient phosphate is required to satisfy the demands for a twofold increase in deoxyribonucleic acid; net ribonucleic acid synthesis is not required. The total ribonucleic acid content of the culture was variable,

5. Metabolic Requirements for Microcycle Sporogenesis of Bacillus megaterium1
Spores of Bacillus megaterium QM B1551 germinated, elongated, and resporulated (microcycle sporogenesis) in simple chemically defined media which permitted no cell division. The second-stage spores thus produced were heat-stable and required heat activation for germination. The original amount of spore deoxyribonucleic acid tripled before completion of the c

6. Microcycle Sporogenesis of Bacillus cereus in a Chemically Defined Medium
A chemically defined medium which allowed germination, outgrowth, and subsequent resporulation of Bacillus cereus T spores, without intervening cell division (microcycle sporogenesis), is described. No medium replacement was required. The second-stage spores were heat-stable and had similar germination characteristics and dipicolinic acid content to primary

7. ENDOGENOUS FACTOR IN SPOROGENESIS IN BACTERIA II. : Growth and Sporulation in Bacillus subtilis1
Kerravala, Zarrine J. (University of Illinois, Urbana), V. R. Srinivasan, and H. Orin Halvorson. Endogenous factor in sporogenesis in bacteria. II. Growth and sporulation of Bacillus subtilis. J. Bacteriol. 88:374–380. 1964.—The presence of an endogenous factor in Bacillus subtilis which could initiate sporogenesis in suspensions of washed vegetative cel

8. Role of Acetate in Sporogenesis of Bacillus cereus
Nakata, H. M. (Washington State University, Pullman). Role of acetate in sporogenesis of Bacillus cereus. J. Bacteriol. 91:784–788. 1966.—The distribution of radioactivity associated initially with acetate-2-C14 was followed during sporogenesis of Bacillus cereus strain T. This was accomplished by replacing cells committed to sporulation into a chemicall
