A broadly resolved molecular phylogeny of New Zealand cheilostome bryozoans as a framework for hypotheses of morphological evolution

R. J. S. Orr, E. Di Martino, D. P. Gordon, M. H. Ramsfjell, H. L. Mello, A. M. Smith, L. H. Liow

The paper constructs a molecular phylogeny of New Zealand cheilostome bryozoans to test morphological evolution hypotheses and finds that lower taxonomic levels are robust while higher-level systematics need rethinking.

Compartmentalization of mRNAs in the giant, unicellular green algae Acetabularia acetabulum

I. J. Andresen, R. J. S. Orr, K. Shalchian-Tabrizi, J. Brate

The paper uses RNA-seq to analyze mRNA distribution in Acetabularia acetabulum, finding localized mRNA pools and even distribution of transport-related transcripts.

Enigmatic Diphyllatea eukaryotes: Culturing and targeted PacBio RS amplicon sequencing reveals a higher order taxonomic diversity and global distribution

R. J. S. Orr, S. Zhao, D. Klaveness, A. Yabuki, K. Ikeda, W. M. Makoto, K. Shalchian-Tabrizi

The paper cultures Diphyllatea strains, amplifies full 18S rRNA genes using PacBio RS II, and identifies three clades, revealing two morphotypes and broader global distribution.
