Arbuscular mycorrhizal (AM) fungi are multinucleate, coenocytic, obligate symbionts with no known sexual stages and very wide host and habitat ranges. While contributing vitally to the growth of land plants they face unique challenges in metabolism, transport, growth and development. To provide clues to the strategies that AM fungi have adopted, random sequencing of cDNA's from Glomus intraradices was undertaken. Putative genes for enzymes, transporters, structural proteins and cell-cycle regulatory factors were discovered. Among the EST's of particular interest are sequences with homology to known trehalase, arsenite transporter, cysteine synthase, tubulins, actin, dynein, cell cycle regulatory proteins, and three meiosis-related proteins. The significance of these sequences is discussed in the context of what is known about AM metabolism, transport, growth and phylogeny.
