Abstract:
Surface-penetrating phytopathogenic fungi frequently form appressoria. These are specialised infection structures pivotal to fungal ingress into the host. Recently, we demonstrated that one member of a family of cutinases in Magnaporthe grisea is involved in surface sensing, mediating appressorium differentiation and penetration peg formation and hence facilitates host penetration. Cutinase2 serves as an upstream activator of cAMP/PKA and DAG/PKC signalling cascades and is essential for full virulence. Here, we speculate on the role of rice blast hydrophobins as surface interactors facilitating fungal cutinase activity.

Mechanism of Filopodia Formation
Their main function is to guide migrating cells during normal tissue morphogenesis or cancer metastasis by recognizing and making initial contacts with the extracellular matrix. However, they can also act as stationary cell anchors or help to establish communication...
Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
