Theory of cell body lensing and phototaxis sign reversal in "eyeless" mutants of Chlamydomonas.

Physical review. E - 1 Jul 2026

Birwa Sumit Kumar, Yang Ming, Pesci Adriana I, Goldstein Raymond E

Abstract excerpt

Phototaxis of many species of green algae relies upon directional sensitivity of their membrane-bound photoreceptors, which arises from the presence of a pigmented "eyespot" behind them that blocks light passing through the cell body from reaching the photoreceptor. A decade ago it was discovered that the spherical cell body of the alga Chlamydomonas reinhardtii acts as a lens to concentrate incoming light, and...
