Chromosome Breakage with Plant Pigments


LATELY, the property of the bacterial products in causing chromosome breakage has been worked out by certain authors1–5. Such results have been taken to indicate the mutagenic property of the soil accounting for spontaneous mutation and chromosome breakage. Several algal groups, too, form an important constituent of the soil, and it was desired to find out how far their decomposition products contribute to the mutagenic property of the substratum.
