The Alanine:Glyoxylate-Aminotransferase ( agt1 ) gene model in Arabidopsis thaliana and in Peperomia cyclaminoides. The gene model for the agt1 gene in P. cyclaminoides Pe114 was derived from both genomic and cDNA sequences. Compared with the gene model in Arabidopsis thaliana, Peperomia cyclaminoides has an additional intron (intron X) that is 380 bp long and located in exon II. This intron can be found among all sequenced Peperomia accessions and ranges in length from 211-390 bp. We also checked its presence in a number of sequenced plant genomes available in Phytozome (v.7.0); the intron is absent only from Arabidopsis and grasses. Since it can be found in papaya, we suggest two independent losses of this intron: within the diversification of both Poaceae (or possibly a larger monocot group) and Brassicales.
