Abstract |
Sycamore (Acer pseudoplatanus L.) calluses resistant to azaguanine were isolated after mutagenesis with nitrosoguanidine. One callus SNC61 was highly variable in its growth on 10 μg/ml azaguanine and it was concluded that its resistance was not due to a stable alteration in the callus. Another callus SNE31 was isolated after 4.5 months culture in 0.5 or 1 μg/ml azaguanine which had a 10-fold increase in resistance to azaguanine. This was shown to be accompanied by a reduction to 50% of the normal level of hypoxanthine phosphoribosyltransferase (E.C.2.4.2.8).
