Abstract

Paralyzed flagellar mutants pf-1, pf-2, pf-7, and pf-18 of the green alga Chlamydomonas reinhardtii (Dangeard) were shown to store a significantly greater amount of starch than the motile wild type 137c+. The increase in starch storage was significant relative to protein, chlorophyll, and cell number. Analysis of average cell size revealed that the paralyzed mutants were larger than the wild type. This increase in storage molecule accumulation supports an inverse relationship between chemical energy storage and energy utilization for biomechanical/motile cellular functions. Chlamydomonas reinhardtii provides a useful model for studies of the role of cytoskeletal activity in the energy relationship and balance of organisms.
