||"In order to identify the metabolites
available to the embryo and measure their levels, ethanolic
extracts from vascular tissues collected 12 days after pollination
(DAP) were analyzed by 1H-NMR (Figure S1)."
glucose, alanine, glutamine and fumaric acid were
identified in the extracts at 13±2, 94±15, 1.0±0.5, 6±1
and 5.0±0.1 mM, respectively. This composition was found
to be very similar to that in phloem."
