Vladimir Andreevich Tranzschel

Vladimir Andreevich Tranzschel (Russian: Владимир Андреевич траншель) (January 16 [O.S. January 4] 1868–January 21, 1942) was a Russian botanist, mycologist and plant pathologist, especially an expert on rust fungi.

Known forTranzschel’s Law in Rust fungus evolution

He graduated from Saint Petersburg University in 1889 and became an assistant at the Imperial Forestry Institute in Saint Petersburg. 1898–1900, he was stationed at the University of Warsaw, but soon returned to Saint Petersburg and took a position a curator at the Botanic Garden of the Imperial Academy of Sciences. He remained affiliated with the Academy for the remainder of his career, from 1912 as senior botanist. He travelled and made collections in European Russia, Germany, Switzerland, Austria, Crimea, Kyrgyzstan, Pamir Mountains, Ussuri and Primorsky.[1]

He is particularly known for Tranzschel's Law, that states that telia of microcyclic species of rust fungi that are descendants of macrocyclic, heteroecious rusts simulate aecia of the ancestral macrocyclic rust and occur on the aecial host of the latter.[2] Tranzschel devised his law to assists in identification of the aecial host of a suspected heteroecious rust by looking for hosts attacked by a microcyclic rust with morphologically similar telia to the former. Modern evolutionary thinking about rust fungi and molecular investigations have confirmed its validity .[3]

In addition, Tranzschel described a number of new species of rust fungi and wrote fungas for various parts of Russia. Together with A. Henckel, Tranzschel also translated Kerner von Marilaun’s Pflanzenleben from German to Russian.[4]

The rust fungus genus Tranzschelia Arthur was named to his honour.[6]
