The constituents of the roots bleeding sap are an important index characteristic of roots activity and roots-shoots relationship. To compare the differences between the constituents of roots bleeding sap from maize and soybean plants, roots bleeding saps were collected from maize (Zea mays L.
Aqueous extracts of human neoplastic and adjacent normal colonic mucosa were investigated for hemagglutination inhibition of both the anti-A serum and the Dolichos biflorus lectin. The anti-A antiserum was inhibited by the extracts from neoplastic tissues to a much higher extent than by that from
We report experiments to quantify the relationships between the relative abundance of ureide-N in root-bleeding sap, vacuum-extracted sap, and hot water extracts of stems and petioles of nodulated soybean (Glycine max [L.] Merrill cv Bragg) and the proportion of plant N derived from nitrogen
Improvement of soybean [Glycine max (L.) Merr.] yield and photosynthesis physiology have been achieved over decades of cultivar breeding. Identification of the mechanisms involved in shoot-root interactions would be beneficial for the development of yield improvement breeding strategies. The
