Giant mitochondria are a response to low oxygen pressure in cells of tobacco (Nicotiana tabacum L.)

J Exp Bot. 2002 May;53(371):1215-8. doi: 10.1093/jexbot/53.371.1215.

Abstract

Low oxygen pressure induces fast and reversible formation of giant mitochondria in cells of Nicotiana tabacum. These can have unusual shapes, attain a length of 80 microm and even form a reticulum. In contrast to animal cells, there is no such response to chemically induced oxidative stress.
