The evolution of land flora was an epochal event in the history planet Earth. success plants, and especially flowering colonizing all but most hostile environments required multiple mechanisms adaptation. mainly polysaccharide-based cell walls which are indispensable for water transport structural support, one important adaptations to life on land. Thus, development vasculature is regarded as a seminal wall evolution, impact further refinements diversification compositions architectures radiation plant families less well understood. We approached this from glyco-profiling perspective and, using carbohydrate microarrays monoclonal antibodies, studied 287 species selected represent evolutionary dichotomies adaptation variety habitats. results support conclusion that indeed accompanied by changes fine structure these can obscure earlier events. Convergent identified our analyses do not appear be associated with plants similar lifestyles taxonomically distantly related. conclude linked phylogeny more strongly than habitat or lifestyle propose there many approaches any given ecological niche.
