Encyclopedia
Theodor Hartig was a German forestry biologist and botanist. He was the son of Georg Ludwig Hartig
(1764–1837), a German agriculturist. His son Robert
(1839–1901) was also a forestry scientist and mycologist and desbribed the Hartig net
, a hyphal network that extends into the plant root.
Hartig was the first to discover and name the sieve tube element
cells (as Siebfasern - sieve fibres and Siebröhren - sieve tubes) in 1837.
As Hartig described many gall wasp species, his zoologist author abbreviation is Hartig.

Sieve tube element
Sieve tubes are mainly to transport sugars and nutrients up and down the plant. In plant anatomy, sieve vascular tissue tube elements, also called sieve tube members, are a type of elongated sclerenchyma cells in phloem tissue. The ends of these cells are connected with other sieve elements, and...
