 Based on the complete genome sequence, XopAI (XAC3230) was proposed as a Hrp regulon candidate (da Silva //et al.//, 2002). Based on the complete genome sequence, XopAI (XAC3230) was proposed as a Hrp regulon candidate (da Silva //et al.//, 2002).
  
-Co-regulation of //xopAI// with other HrpG-controlled genes was also proposed by Noël //et al.// (2006) based on the observation that 200 bp of the 5' sequence including promoter and coding regions of //xopE2// (//avrXacE3//) and //xopAI// (XAC3230) from //X. citri// pv. //citri// are more than 85% identical to the corresponding region of //xopJ//, which is a member of the HrpG regulon from //X. euvesicatoria// pv. //euvesicatoria// (ex //X. campestris// pv. //vesicatoria//).+Co-regulation of //xopAI// with other HrpG-controlled genes was also proposed by Noël //et al.// (2006) based on the observation that 200 bp of the 5' sequence including promoter and coding regions of //xopE2// (//avrXacE3//) and //xopAI// (XAC3230) from //X. citri// pv. //citri// are more than 85% identical to the corresponding region of //xopJ//, which is a member of the HrpG regulon from //X. euvesicatoria// pv. //euvesicatoria// (ex //X. campestris// pv. //vesicatoria//).
  
 Based on homology to effectors from //Pseudomonas syringae// and a strongly conserved 43‐amino‐acid N‐terminal domain that is also found in the N‐termini of effectors in class XopE and XopJ, XopAI was proposed to be a T3E (Stavrinides //et al.//, 2006; White //et al.//, 2009). Based on homology to effectors from //Pseudomonas syringae// and a strongly conserved 43‐amino‐acid N‐terminal domain that is also found in the N‐termini of effectors in class XopE and XopJ, XopAI was proposed to be a T3E (Stavrinides //et al.//, 2006; White //et al.//, 2009).
