 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).

-Using microarrays, seven T3E genes from //X. citri //pv. //citri// were found to be upregulated in planta, five of which in all the three times investigated, i.e. 24 hpi, 72 hpi and 120 hpi (//xopE1//, //xopN//, //xopK//, //xopE3//, //xopAI//), and the two remaining at the later times of the infectious process (//xopE2// and //xopV//) (de Laia //et al.//, 2019).+Using microarrays, seven T3E genes from //X. citri// pv. //citri// were found to be upregulated in planta, five of which in all the three times investigated, i.e. 24 hpi, 72 hpi and 120 hpi (//xopE1//, //xopN//, //xopK//, //xopE3//, //xopAI//), and the two remaining at the later times of the infectious process (//xopE2// and //xopV//) (de Laia //et al.//, 2019).

-XopAI is conserved in the Citrus canker strains, including //X. citri// pv. //citri// and //X. citri// pv. //aurantifolii // (ex //X. fuscans// pv. //aurantifolii//) (Moreira //et al.//, 2010).

-XopAI homologs were also found in //X. citri// pv. //bilvae// and //X. citri// pv. //glycines//, as well as in the species //X. arboricola//, //X. hortorum//, //X. vesicatoria// (Moreira //et al.//, 2010;  Liu //et al.//, 2019).+XopAI homologs were also found in //X. citri// pv. //bilvae// and //X. citri// pv. //glycines//, as well as in the species //X. arboricola//, //X. hortorum//, //X. vesicatoria// (Moreira //et al.//, 2010; Liu //et al.//, 2019).
