Other claims from this paper (7)
- Observation No significant cytoplasmic pH gradient was observed within the apical 50 microm of growing cells in any of the three tip-growing cell types.
- Observation Mean cytoplasmic pH of dye-ester-loaded cells was estimated at 7.15 to 7.25 for the three cell types.
- Intervention effect Acidifying or alkalinising the cytoplasm of Neurospora hyphae slowed growth but did not abolish it.
- Intervention effect Manipulating cytoplasmic pH of Agapanthus pollen tubes completely inhibited growth.
- Intervention effect Manipulating cytoplasmic pH of Dryopteris rhizoids completely inhibited growth.
- Intervention effect Modifying external pH affected the growth pattern of all cell types.
- Intervention effect In hyphae and pollen tubes, changes in external pH had a small transient effect on cytoplasmic pH and the cells rapidly readjusted to their original pH.
