Solanum tuberosum glucan synthase-like 05 is involved in root-knot nematode Meloidogyne hapla parasitism.

ABSTRACT: The Glucan Synthase-like 5 (GSL05) gene in potato is homologous to the Arabidopsis GSL05 that has a role in defense-related callose deposition. The role of GSL05-mediated callose deposition in potato roots during root-knot nematode Meloidogyne hapla infection was investigated. Silencing GSL05 in potato resulted in reduced elicitor-induced callose deposition in roots. When StGSL05 knockdown plants were inoculated with nematodes, more second-stage juveniles (J2s) successfully penetrated the roots and formed galls, suggesting a weakened callose-based physical barrier against nematode invasion and supporting the hypothesis that StGSL05 contributes to basal defense. Despite the increased nematode penetration and gall formation, the StGSL05 knockdown plants did not exhibit more egg masses or tot
