The Evolution of Plant Physiology
In the majority of those that are subaerially dispersed, birds and insects are the
dispersal vector and the sporopollenin is likely to protect against enzymatic
digestion in the digestive tracts. In any case, the presence of a sporopollenin wall
might ...

Pollen and Pollination
Sporopollenin may be isolated by acetolysis, a technique widely used in
palynology (Wiermann and Gubatz 1992), since it is the only component resistant
to this reaction (Erdtman 1960). According to this technique polliniferous material
is ...
