- ... Experiments were conducted to test the hypothesis that cellular compounds, especially wall‐associated compounds, released during emergence of secondary roots, stimulate the growth of arbuscular mycorrhizal (AM) fungi. Purified cell walls, crude cell‐wall extracts, crude cytoplasmic extracts, and phenolic compounds previously identified as cell wall‐associated, from Ri T‐DNA‐transformed roots of ho ...

- ... Vesicular-arbuscular mycorrhizal fungi are symbionts for a large variety of crop plants; however, the form in which they take up carbon from the host is not established. To trace the course of carbon metabolism, we have used nuclear magnetic resonance spectroscopy with [13C]glucose labeling in vivo and in extracts to examine leek (Allium porrum) roots colonized by Glomus etunicatum (and uncolonize ...
