- Observation Rust fungus gall development caused hyperplasia of the epidermis and spongy parenchyma in Byrsonima variabilis.
- Mechanism Cell-to-cell translocation of metabolites from mesophyll cells toward the rust gall is favoured by homogalacturonan and arabinan epitopes detected at hyphae passage sites in the pycnial and aecial stages.
- Mechanism Arabinogalactan-proteins may favour mycelial nutrition and differentiation and cell wall adhesion of the rust fungus.
- Mechanism Homogalacturonans and arabinans confer porosity to mesophyll cell walls, which favours the traffic of molecules toward the rust fungus gall.
- Observation Labelling of arabinogalactan-proteins, homogalacturonans and arabinans was unexpectedly detected in fungal cell walls, a novelty for the plant-fungus interaction.
- Mechanism Primary metabolites detected in the rust fungi support hyphae growth and spore maturation.
