❯ … Find the orthologs of Arabidopsis NAC001 (AT1G01010) in rice and maize. …
  6 calls, ×2 each: gramene_homologs · orthodb_orthologs · gene_tree_members

Rice: one ortholog, Os07g0683200. Gramene (v69) classes it as
ortholog_one2many, and the current Ensembl Compara gene tree
(EPlGT01160000455820) has it as the only rice member.

Maize: none found. Neither Gramene nor the current Ensembl gene
tree lists a maize member for AT1G01010.

What OrthoDB adds: OrthoDB (v12) puts NAC001 in the group "NAC
domain-containing protein" (261582at33090) … That group has no rice or
maize members. So the rice match rests on Gramene and Ensembl, which
use the same Compara pipeline, and OrthoDB does not back it up.

… Maize clearly has NAC genes, but none falls in NAC001's tree. …
