Abstract: -(Histochemistry and ultrastructure of the ontogenesis of the tetrasporangia of Hypnea musciformis (Wulfen) J. V. Lamour. (Gigartinales, Rhodophyta)). Tetraspore development was studied in Hypnea musciformis (Wulfen) J. V. Lamour. using light and electron microscopes, and techniques of histochemistry. Tetrasporangial differentiation arises from a cortex cell that enlarges. This cell undergoes mitosis to form a tetrasporangial mother cell and a stalk cell. The histochemichal study indicated that the cell wall l… Show more

“…TB-O staining produces a violet metachromatic reaction in the cell walls of all sections of G. domingensis as seen in green and red strains of K. alvarezii (Schmidt et al, 2009), Chondrus crispus (Gordon and McCandless, 1973), Chondria tenuissima C. Agardh (Tsekos, 1985) and H. musciformis (Bouzon, 2006). This metachromatic reaction is used in histological studies as an indicator of acidic polysaccharides (Gordon-Mills et al, 1978).…”

“…Regiões eletrontransparentes, também denominadas regiões fibrilares ou genóforos, foram observadas na região central dos cloroplastos. Nessa região, estaria localizado o DNA dos cloroplastos (Bouzon, 2006 (Poppe et al, 2003), indicando uma maior sensibilidade dos cloroplastos à UV-B, quando comparados a outras estruturas celulares. Alterações similares nos tilacóides foram também observadas em Odonthalia dentata, como conseqüência do tratamento com radiação UV-B (Holzinger et al, 2004).…”
