An hsp70 homolog is encoded on the plastid genome of the red alga, Porphyra umbilicalis.

M Reith1, J Munholland.   

Abstract

A PCR experiment using Porphyra umbilicalis DNA as the template and degenerate oligonucleotides representing conserved regions of hsp70 amino acid sequences generated a 1 kb product that hybridized exclusively to the plastid DNA of this red alga. DNA sequencing of two contiguous EcoRI plastid DNA clones revealed a 620 amino acid open reading frame with 71% identity to the dnaK gene of the cyanobacterium, Synechocystis 6803. Northern hybridization experiments detected a 2.3 kb transcript that is present in control (15 degrees C) cultures and increases approximately 7-fold upon heat shock (75 minutes at 30 degrees C).
