We isolated the cDNA for a sigma factor from the moss Physcomitrella patens, which possesses unusually large N-terminal extension and the conserved subdomains 1.2-4.2. Phylogenetic analyses indicated that this novel sigma factor and PpSIG1*(2), a plastid sigma factor previously identified from Physcomitrella, were classified into SigA and SigB groups, two major classes of higher plant plastid sigma factors, respectively. According to the nomenclature recently proposed, we renamed PpSIG1* into… CONTINUE READING
