Supplemental Figure S1. Summary of cell wall epitope detection in Arabidopsis, Lepidium and tobacco seeds.

(ME) = micropylar endosperm, (LE/CE) = peripheral and chalazal endosperm, (Em) = embryo, (T) = testa, (M) = mucliage.
(-) = probe did not bind, (+), (++) and (+++) = relative amount of probe binding for each tissue where (+) denotes weak binding and (+++) denotes intense binding.
(a) = restricted to embryo surface / inner face of endosperm.
(b) = abundant in cotyledons. [+] and [+++] = detectable upon enzyme deconstruction of the wall.
