Welcome to Hyphomonas.com

Hyphomonas is an alphaproteobacterial species that doesn't divide by binary fission -- instead, Hyphomonas cells divide by asymmetric budding. In the EM photo above, a mother cell of Hyphomonas adhaerens (shown on the left) is forming a daughter bud (shown on the right). The DNA, proteins, and other components must pass through the stem structure. The mother cells are non-motile while the daughters are motile until they become mother cells themselves. Therefore, Hyphomonas has promise as a simple model of development.

The genome of Hyphomonas neptunium ATCC 15444 is now in Genbank as Refseq entry NC_008358. We hope that this will further interest in this fascinating microbe.
