Three Proteins (Hpa2, HrpF and XopN) Are Concomitant Type III Translocators in Bacterial Blight Pathogen of Rice

Abstract: Type III (T3) proteic effectors occupy most of the virulence determinants in eukaryote-pathogenic Gram-negative bacteria. During infection, bacteria may deploy a nanomachinery called translocon to deliver T3 effectors into host cells, wherein the effectors fulfill their pathological functions. T3 translocon is hypothetically assembled by bacterial translocators, which have been identified as one hydrophilic and two hydrophobic proteins in animal-pathogenic bacteria but remain unclear in plant pathogens. Now we… Show more

“…The former is conceived as a translocon formed by interactions of T3 translocators with each other and with PM constituents (B€ uttner, 2016; Figure 6I), either lipids (B€ uttner et al, 2002;Haapalainen et al, 2011;Lee et al, 2001) or proteins (Goure et al, 2004;Li et al, 2015Oh and Beer, 2007). Known T3 translocators include one hydrophilic protein (Ji and Dong, 2015a), such as Hpa1 of xanthomonads, and two hydrophobic proteins (B€ uttner, 2016;Ji and Dong, 2015a), such as HrpF (B€ uttner et al, 2002) and XopN (Mo et al, 2020) of xanthomonads. In the model, recognition of the hydrophilic translocator by a PM constituent is the first step towards translocon assembly (Goure et al, 2004;Mueller et al, 2008).…”
