Accumulation of radioactive phosphorus-32 or sulphur-35 in the lesions produced by various treatments of the leaves of some Nicotiana plants water-cultured with the isotopes was tested. Zonate accumulation of phosphorus-32 was found at the tobacco leaf spots produced by 2 per cent CuSO_4 and by saturated KClO_3 solutions; especially at the lesions produced by the latter the accumulation of phosphorus-32 was more conspicuous than by the former. No accumulation of the isotopes was found in the case of 0.5 percent HCl. Accumulation of phosphorus-32 or sulphur-35 was not observed at the punched portions by cork borer of tobacco leaves even after 6 days from treatment at room temperature. Accumulation of phosphorus-32 or sulphur-35 was found at the necrotic spots of N. glutinosa inoculated with TMV 48 hoursbeforesampling.
