Figure 1From: Selenite activates the alternative oxidase pathway and alters primary metabolism in Brassica napus roots: evidence of a mitochondrial stress responseSelenite induces the accumulation of mitochondrial superoxide. Three-week old B. napus plants were treated with 50 μM selenite for the time indicated, at which point root tips were excised and incubated with the fluorescent probe MitoSox. Epifluorescence of Mitosox was representative of 8–10 root tips from 5 different plants.Back to article page
