Abstract
Fourteen genes encoding proteins of the light harvesting complex (Lhc) are expressed in a photoautotrophic cell culture from the wild species of tomato (Lycopersicon peruvianum). For two genes, Lhca2 (cab7) and Lhcb2(*)1 (cab4), a rhythmic oscillation of the transcript accumulation is observed under light/dark and constant dark conditions indicating that gene expression is controlled by a circadian clock in the tomato cell culture. The circadian expression of the Lhc genes remains present after application of 2,2'-dipyridyl. However, the amplitude of Lhc mRNA oscillations and the photosynthetic capacity (Fmax/Fo) decrease significantly. The transcript accumulations of psbA, rbcS and rbcL are less or not at all affected by 2,2'-dipyridyl.
