  • Title: Morphometric analysis of cell size patterning involved in gravitropic curvature of the stipe of Coprinus cinereus.
    Author: Greening JP, Moore D.
    Journal: Adv Space Res; 1996; 17(6-7):83-6. PubMed ID: 11538640.
    Abstract:
    During gravitropic bending of the stipe of Coprinus cinereus the majority of elongation occurred in the apical region of the lower surface of the stipe, although some elongation was seen throughout the stipe. The final rate of elongation was similar at both the upper and lower stipe surfaces but the lower surface achieved this rate first (close to the reaction time 25 min), whilst the upper surface of the stipe only attained its final elongation rate after a period of acceleration of 150 min. Detailed morphometric analysis of cell size patterning in transverse sections revealed no significant differences in cross sectional area, spatial or proportional distribution of different cell types between the upper and lower regions of the gravitropic bend. Measurements of longitudinal cell size revealed significant differences in compartment size between the lower and upper region. Hyphal compartments of lower regions of the bend were on average four to five times longer than those of the upper region.
