22080591-4	2012	In this study, we investigated the enzymatic activities of two Arabidopsis thaliana GT43 members, IRX9 (Irregular Xylem9) and IRX14, which have been genetically shown to be non-redundantly involved in the elongation of the xylan backbone.	Xylans	223-228	Nucleotide-diphospho-sugar transferases superfamily protein	Arabidopsis thaliana	126-131	
22080591-9	2012	Together, these findings provide the first biochemical evidence that IRX9 and IRX14 are xylosyltransferases that operate cooperatively in the elongation of the xylan backbone.	Xylans	160-165	Nucleotide-diphospho-sugar transferases superfamily protein	Arabidopsis thaliana	78-83
