A phytochrome regulated pea transcript encodes ferredoxin I

Abstract
We have sequenced the pea (cv. Alaska) cDNA clone pEA46 (16) and shown that it codes for ferredoxin I. This clone has previously been shown to correspond to a transcript whose levels are controlled by phytochrome (Kaufman et al. (1985) Plant Physiol. 78: 388–393; Thompson et al. (1983) Planta 158: 487–500). The deduced amino acid sequence includes part of an hydrophobic transit sequence that shows only very limited homology to that of Silene pratensis ferredoxin. Genomic blotting analysis indicates that ferredoxin I is encoded by one or two genes. A genomic clone (4601) has been isolated that contains the ferredoxin gene and at least 14 kb of flanking sequences.
