jpy12130-sup-0001-FigureS1.TIFimage/tif161KFig. S1. Maximum likelihood tree of 33 Pseudo-nitzschia strains based on LSU rDNA sequences. Nodal support corresponded to maximum likelihood bootstrap vales and Bayesian posterior probability vales (ML/BI). Pseudo-nitzschia inflatula (AF417639) was used as outgroup. Local strains and new species in bold.
jpy12130-sup-0002-FigureS2.tifimage/tif1464KFig. S2. ITS2 secondary structures for Pseudo-nitzschia arbrensis and P. caciantha, the closest species in the ITS phylogenetic tree. Many differences can be observed both in nucleotide sequences and in bulge conformation.
