Query: NC_009464:650997 Uncultured methanogenic archaeon RC-I, complete genome
Lineage: Methanocella arvoryzae; Methanocella; Methanocellaceae; Methanocellales; Euryarchaeota; Archaea
General Information: This organism is a key methane producer in the rhizome of rice. A large portion of the methane that is emitted in rice fields is produced by methanogenic archaea. Rice Cluster I (RC-I) methanogens in the rice rhizosphere play a key role in this methane production.
