A Working Model of MoAbp1 Function

Caption

During growth, appressorium formation, and infection of Magnaporthe oryzae, the actin network is a very dynamic structure with continuous polymerization and disassembly. MoAbp1 is localized to actin patches through the actin-depolymerizing factor homology (ADFH) domain. It recruits MoArk1 and MoCap1 to actin patches through the free SH3 (F-SH3) and extended SH3 (E-SH3) domains, respectively. In this way, MoAbp1 mediates endocytosis and F-actin assembly to regulate growth and pathogenicity in M. oryzae. Solid arrows indicate conclusions based on our studies.
