MORPHOLOGY OF CELL WALL PORE CHANNELS IN GENUS EUASTRUM RALFS (DESMIDIALES)
Abstract
The study of the cell wall structure was performed for 10 species of Euastrum – E. ansatum (Ehrenb.) Ralfs, E. bidentatum Näg., E. binale (Turp.) Ehrenb. ex Ralfs, E. dubium Näg., E. elegans (Bréb.) Kütz. ex Ralfs, E. germanicum (Schmidle) W. Krieger, E. oblongum (Grev.) Ralfs ex Ralfs, E. pectinatum Bréb. ex Bréb. in Ralfs, E. validum West et G.S.West, E. verrucosum (Ehrenb.) ex Ralfs. The investigation of the cell wall ultrastructure has established, for the first time, that the pore canal in 6 of 10 species always has to some degree coiled form. Three species (E. germanicum, E. pectinatum и E. verrucosum) have both coiled and straight canals, and E. ansatum – only straight ones. Also new type of pores (P7), typical only for representatives of the genus Euastrum, was noted. Besides, simple and effective method of preparing desmidium algal cells for investigation with transmission electron microscope has been developed.
