Unusual Features of the Light Response System Regulating Ferredoxin Gene Expression
The ferrdoxin gene system. Recently we identified a cDNA clone encoding ferredoxin I and showed that the level of the corresponding transcript in pea seedlings is increased by white light (Sagar et al., 1988a, b) and by red light acting through the phytochrome system (Dobres et al., 1987; Kaufman et al., 1985, 1986). The light responses of this gene — which we have designated Fed-1 — differ strikingly from those of RbcS and Cab which have so far served as the main models for light responsive genes, providing us with an opportunity to significantly broaden our understanding of light regulatory mechanisms.
