Morphology and ultrastructure of Schizaea fistulosa (Schizaeaceae) spores from Chile

The spores of Schizaea fistulosa from Chile were studied using light microscopy (LM), scanning (SEM) and transmission electron microscopy (TEM). The spores are monolete and elliptic in polar view. The major equatorial diameter is 71-85 µm and the polar diameter is 54-61 µm. The laesurae are 50-60 µm...

Ramos Giacosa, Juan P. Morbelli, Marta A. Giudice, Gabriela E. Schizaeaceae Schizaea fistulosa esporas morfología ultraestructura. Schizaeaceae Schizaea fistulosa spores morphology ultrastructure. The spores of Schizaea fistulosa from Chile were studied using light microscopy (LM), scanning (SEM) and transmission electron microscopy (TEM). The spores are monolete and elliptic in polar view. The major equatorial diameter is 71-85 µm and the polar diameter is 54-61 µm. The laesurae are 50-60 µm long and, in some cases, bifurcated. The sporoderm ultrastructure is first mentioned and described here. The exospore is two-layered in section, verrucate-tuberculate with single or fused elements forming short ridges. The perispore is single-layered, 10-30 nm thick and it is only visible under transmission electron microscopy. On the spore surface, numerous, single or fused, spheroids and nanospheroids of different sizes were observed attached to the perispore surface. The results are discussed and compared with previous studies in Schizaea Morfología y ultraestructura de las esporas de Schizaea fistulosa (Schizaeaceae) de Chile. Se estudiaron las esporas de Schizaea fistulosa de Chile con microscopía óptica (MO), electrónica de barrido (MEB) y transmisión (MET). Las esporas son monoletes y elípticas en vista polar. El diámetro ecuatorial mayor es de 71-85 µm y el diámetro polar de 54-61 µm. Las lesuras son de 50-60 µm de longitud y en algunos casos están bifurcadas. La ultraestructura de la esporodermis se describe por primera vez. El exosporio en sección posee dos capas y es verrucoso-tuberculado con elementos aislados o fusionados formando lomos cortos. El perisporio posee una sola capa, de 10-30 nm de espesor y solamente es visible con microscopía electrónica de transmisión. Sobre la superficie de la espora, se observan numerosos esferoides y nanoesferoides de diferentes tamaños, adheridos a la superficie. Se discuten los resultados y se los compara con estudios previos en Schizaea.
