Cryptomonadales

Chilomonas amygdalum Kent, 1880. Colourless cryptomonads, with stiff elongate-ovate body, almond-shaped, somewhat curved towards the ventral aspect, from three to four times as long as broad, flagella subequal, longer than the cell, endoplasm transparent, granular. Length 12.7 microns

Cryptomonas (crypt-oh-moan-ass), a common genus of cryptomonad flagellates with chloroplasts. There are two flagella which insert into a groove which opens subapically (the dent near the front of the cell is where is opens). The flagella can be seen upper left. Special extrusomes (ejectisomes) form a little cluster around the flagellar pocket (the pocket can not be seen). Off green chloroplasts, and the orange pink item to the right side is a crystalline inclusion encountered in many cryptomonads. With numerous small polysaccharide inclusions. Differential Interference Contrast.

Cryptomonas, a common cryptomonad flagellate. Prominent extrusomes are seen lining an invaginated canal anteriorly. Two flagella (not well seen in this image) emerge from the canal. The nucleus is seen just posterior to the linear array of extrusomes. This is a relatively large species approximately 45 microns long. From freshwater pond near Boise, Idaho. Brightfield illumination.

Plagioselmis prolonga has an unusual nucleomorph genomic structure, in that it lacks the ribosomal cistrons thought to be at the ends of all nucleomorph chromosomes. Based on its distant relationship to the only cryptomonad which has had its necleomorph genome sequenced, Guillardia theta, we expect the nucleomorph of P. prolonga to help elucidate the mechanisms behind genome reduction following secondary endosymbiosis.
