Summary
The mitotic cycle in root apical meristems of mycorrhizal and non-mycorrhizal plants ofAllium porrum L.+Glomus sp., strain E3, has been examined by3H-TdR labelling. Significant slowing down of the mitotic cycle in the mycorrhizas through an extension of G1, S and metaphase was observed, while G2 was drastically reduced. Lengthening of the cycle was proportional to increasing infection. The ways in which the fungus could influence cell division are discussed.
