Indirect immunofluorescence detection of heteromannan in medial transverse sections of wheat (a, c) and rice (b, d) grains at 12 DAA. Micrographs c and d are ×4 enlargements of the outer endosperm regions of micrographs a and b to show that the heteromannan signal is present throughout the endosperm and sub-aleurone tissues in wheat, but remains absent in rice. M maternal pericarp, N nucellus, NP nucellar projection, NE nucellar epidermis, SA sub-aleurone, Al aleurone, I integuments, SE starchy endosperm, VB vascular bundle, ETC endosperm transfer cells, SC seed coat.
