 === How discovered? ===
-The //xopAM// gene in //X. campstris// pv. //campestris// strain 8004 (Xcc8004) was identified as a candidate T3E due to the presence of a PIP box (TTCGB-N<sub>15</sub>-TTCGB) within  the  upstream  sequence  of  its  putative  translational  start  codon (Jiang //et al.//, 2009).

 === (Experimental) evidence for being a T3E ===
-Using the HR-inducing domain AvrBs1<sub>59-445</sub> as a type-3 translocation reporter, the N-terminal region of XopAM<sub>Xcc8004</sub> was found to act as a type 3 secretion signal, since the translational reporter fusion triggered a //Bs1//-specific hypersensitive response in a //hrpF//- and //hpaB//-dependant manner (Jiang //et al.//, 2009).

-Using a promoterless β-glucuronidase (//gus//) gene as a transcriptional reporter, //xopAM// <sub>Xcc8004</sub> was found to be under control of HrpG and HrpX (Jiang //et al.//, 2009).
