Other claims from this paper (8)
- Observation Other Erysiphe species formed five-lobed appressoria through successive 120-degree branching within six hours.
- Observation Each branching produced a dormant outward lobe and a growing inward limb that formed varied curved structures.
- Observation Extracellular outlines confirmed the observed branching pattern.
- Observation Some appressorial lobes redivided after 36 hours into botryose, jigsaw or candelabra-like patterns.
- Observation Conidia developed one true germ tube, with rare secondary unswollen tubes.
- Observation On host surfaces, secondary tubes and appressorial extensions grew into colony-forming hyphae.
- Observation Lobed appressoria of Neoerysphe and Phyllactinia branched at 120 degrees.
- Observation Podosphaera xanthii showed a simpler appressorial branching pattern.
