Pathogenic lifestyle and infection process of M. phaseolina. (a) Conidia or sclerotia are released from the pathogen. (b) Conidia or sclerotia disperse during early rainy season and contact the host tissue with the aid of transglutaminase-like proteins and cellulose-binding elicitor lectin. (c) Pathogen neutralizes the initial host defense with salicylate-1-monooxygenase. (d) Conidia form appressorium under the control of the central regulator PMK1. (e) Penetration peg invades into the plant epidermis. (f) Inside the host, the pathogen releases an array of different toxins and cell wall degrading enzymes and finally breakdown the host defense. (g) Results in host cell death and self-establishment.
