<p>Protein domain analysis of CrTAA1 and its homologs.</p>

Protein domains of CrTAA1 and its homologs in Ceratopteris richardii were analyzed and compared with the five Arabidopsis TAA1 and TAR homologs. Protein sequences and IDs were retrieved from Phytozome (https://phytozome-next.jgi.doe.gov/), and analyzed using the InterPro database (www.ebi.ac.uk/interpro/search/sequence/). Green colors indicate members of the TAA1 and TAR1/2 subgroup, which participate in canonical IAA biosynthesis through the IPyA pathway, while blue colors indicate members of the TAR3/4 subgroup.
