How to get good fungal and bacterial identifications from GenBank sequences

Submitted by Bevan Weir on 29 October, 2014 - 21:44

ncbi logoGenBank from the NCBI is an amazing and invaluable resource for DNA sequences, and combined with the searching tool BLAST it is really easy to identify your unknown gene sequence.

The trouble is that many of the organism identifications of GenBank sequences are dubious, outdated, or just plain wrong. Identifying a sequence as the wrong species is just bad science no matter what your reason, but is especially important for regulatory agencies. The problem of incorrect identifications is a self-compounding problem as these incorrect identifications are used by other sequence submitters to name their sequences.

Agrobacterium or Rhizobium, which name to use?

agrobacteria gall on rootAgrobacterium is a well-known genus in bacteriology and molecular biology, but research has shown that it cannot easily be separated from the Rhizobium genus, thus all Agrobacterium species should be renamed as Rhizobium species (the earlier name). However there has been some opposition to renaming Agrobacterium, in this article I explain the research and taxonomy, and suggest a solution.

Curator of the ICMP

From July this year I am now the curator of the International Collection of Microorganisms from Plants (ICMP) held by Landcare Research in Auckland, New Zealand. This is recognised as a “nationally significant collection” by the NZ government, and is registered as WDCM 589.

The ICMP has a large collection of Bacteria and Fungi isolated from plants and the natural environment. Many of these are important plant pathogens.
