Abstract excerpt

In the mechanism underlying the phototactic behavior of Chlamydomonas, Ca(2+) has been thought to control the dominance between the two flagella so as to steer the cell to correct directions. A newly isolated mutant, lsp1, that displays weak phototaxis was found to be defective in this Ca(2+)-dependent shift in flagellar dominance; in demembranated and reactivated cell models, the trans flagellum (the flagellum...
