Rhizobium sp. Degradation of Legume Root Hair Cell Wall at the Site of Infection Thread Origin

Rhizobium sp. Degradation of Legume Root Hair Cell Wall at the Site of Infection Thread Origin

Applied and Environmental Microbiology 50(3): 717-720

Using a new microinoculation technique, it was demonstrated that penetration of Rhizobium sp. into the host root hair cell occurs at 20 to 22 h after inoculation. The bacterium dissolved the cell wall matrix, leaving a layer of depolymerized wall microfibrils. Colony growth pressure stretched the weakened wall, forming a bulge into an interfacial zone between the wall and plasmalemma.
