KUPREVICH, VASILII FEOFILOVICH (Botanist) 



V. F. Kuprevich was born January 24, 1897. From 1934 to 

 1938, he worked in the Biological Institute of the Byelorussian 

 S.S.R. Academy of Sciences. In 1938, he was made chief of a 

 laboratory of the Botannical Institute of the U. S.S.R. Academy 

 of Sciences, and from 1949 to 1952, he was Director of this 

 Institute. In 1952 V. F. Kuprevich was elected an Academician 

 of the Byelorussian S.S.R. Academy and President of the Acade- 

 my of Sciences of Byelorussian S.S.R. Since 1953 he has been 

 a Corresponding Member of the U. S.S.R. Academy of Sciences. 

 In 1945 V. F. Kuprevich became a member of the Communist 

 Party of the Soviet Union. He is presently a Deputy of the 

 U. S.S.R. Supreme Soviet. 



Kuprevich has studied the physiology and biochemistry of 

 diseased plants and the classification of mushrooms. He has 

 investigated the physiology of diseased plants. He was the first 

 to discover the presence of extracellular enzymes in obligate 

 parasites and proposed progressive curtailment and specializ- 

 ation of extracellular enzymatic apparatus in parasitic mush- 

 rooms in the process of their evolution. The basis of the 

 pathological process is the action of extracellular enzymes of 

 a parasite on the protoplast of the host and responsive reactions 

 of the latter which led to necrosis, or the suppression of the 

 activity of the parasitic enzymes. Kuprevich showed that leaves 

 can assimilate carbon dioxide transmitted along with water 

 from other parts of the plant. These investigations led to the 

 discovery of the feeding process of plants by carbon dioxide 

 from the soil. Kuprevich discovered extracellular enzymes 

 which are secreted by the thinnest roots of higher plants. He 

 proved the possibility of heterotrophenous feeding of higher 

 plants in natural environments and eliminated the principal
