The PCD phenotype results from axonemal abnormalities and dysfunction of motile cilia and flagella. |
However, even under these conditions, cells with flagella have a mating advantage over aflagellate cells in the population. |
In test-tube studies, the enzyme can destroy flagellin whether it's part of a bacterium's flagella or just free-floating in a solution. |
Such differences strongly suggest convergent reduction in the antennal flagella of odonates and mayflies. |
This bacterial strategy is reasonable, since the above-mentioned advantage would be lost if the planktonic cell had peritrichous flagella. |
Cilia and flagella are hairlike organelles extending from the cell surface. |
