Scientists have mapped two distinct routes the gray mold fungus Botrytis deweyae uses to invade Solomon's seal leaves, and identified the molecular pathways it activates to survive once inside, laying groundwork for targeted treatments against this disease.
1
B. deweyae penetrates P. cyrtonema leaves via two mechanisms: direct surface penetration using secreted gelatinous substances and infection cushions, or entry through stomatal pores
2
The MAPK signaling pathway, specifically the Hog1 gene (K04441), drives the fungus's osmotic stress response inside the host, triggering antioxidant enzyme expression for survival
3
Glyceride metabolism facilitates lipid transport and localization across the cell membrane, actively supporting the infection process
