AB - The mutant, C‐2A′‐34, lacks the β, ϵ‐carotenoids, α‐carotene, lutein and loroxanthin. When grown under heterotrophic or mixotropic conditions this strain develops significantly higher levels of β‐carotene and violaxanthin than does the original developmental mutant of Scenedesmus, C‐2A′. The decrease in chlorophyll a and chlorophyll b observed in C‐2A′‐34 is accompanied by the near absence of the LHC. The light intensity dependence of greening of this strain is comparable to that of C‐2A′; the loss of the β,ϵ‐carotenoids and modification of the pool of β,β‐carotenoids neither prevent the proximal pigment‐protein complexes of photosystems I and II from developing nor cause any short term photosensitivity. The increase in the β,β‐carotenoids in C‐2A′‐34 apparently compensates for the loss of the β,ε‐carotenoids required in formation of the proximal and distal antennae systems but not in the LHCs.
