A phylogenetic tree representing alignment of YGL138(t) protein and its homologues proteins. The rooted neighbor-joining tree using percentage identities was constructed based on a multiple sequence alignment generated with the program Clustal X and MEGA 4. Scale represents percentage substitution per site. Accession numbers of the protein sequences were as follows: Oryza sativa [YGL138(t), RAPDB: Os11g05552]; Coccomyxa sp. C-169 [GenBank: EIE18517]; Nodularia spumigena CCY9414 [GenBank: ZP_01629394]; Actinomyces coleocanis DSM 15436 [GenBank: ZP_03925628]; Arabidopsis thaliana [GenBank: NP_196014]; Micromonas pusilla CCMP1545 [GenBank: XP_003056150]; Sorghum bicolor [GenBank: XP_002442824]; Zea mays [GenBank: NP_001142003].
