Abstract
The cell wall is one of the defining characteristics of plants and is a fundamental
component in normal growth and development. Cell wall composition is a
potentially valuable source of phylogenetic information as notable similarities
and differences exist between and within major embryophyte groups. In
particular, there is a pronounced chemical demarcation between the
eusporangiate pteridophytes (high mannan, low tannin) and the leptosporangiate
pteridophytes (low mannan, high tannin). The results of recent biochemical and
immunocytochemical investigations have shown that changes in cell wall
composition accompanied the bryophyte–lycopodiophyte and
eusporangiate–leptosporangiate transitions.
