Name derivation:
|

|
|

Classification:
|
||||
|
Bumillaria Borzi, 1889; 5 of 6 species descriptions are currently
accepted taxonomically (Guiry and Guiry 2014). Order
Tribonematales;
Family Tribonemataceae |

Flagellar Apparatus:
|
||||
|
With
transmission and scanning electron microscopy, the three-dimensional
structure of the flagellar apparatus of Bumillaria and
other members of the genus Tribonema was investigated. The structure includes a
counterclockwise displacement of basal bodies, two different connective fiber
types, a microtubular and striated root system, and
the emergence of an extensive cytoskeletal mictotubular system from the arching rootlet. (Lokhorst and Star, 2003) |

Inhibition of Photosynthetic Activity:
|
||||
|
In
a study of the effects of bisulfite-sulfite and nitrile on the photosynthetic activity of various algae,
it was found that these solubility products of SO2 and NO2
inhibited photosynthetic activity of the yellow-green algae Bumilleria. In
a 0.10 mM HSO3-/SO32-
solution, Bumilleria exilis photosynthesis
was inhibited 33%, while in a 1.0 mM NO2-
solution it was inhibited by 11% (Wodzinski et al.
1977) |
||||
Evolution:
|
||||
|
Based
on the examination of plastid and nuclear 18S rRNA
of Xanthophyceae, it has been found that coccoid and filamentous species possessing bipartite cell
walls, such as Bumilleria,
form a distinct and previously unrecognized lineage within the class and do
not form monophyletic orders between the Mischococcales
(cocccoid) and Tribonematales
(filamentous) – the order to which Bumilleria belong.
