摘要

In their review of mitochondrial redox biology in plants, Graham Noctor et al. [1] discuss the role of stromules (stroma-filled plastid tubules [2,3]) in the transport of metabolites and proteins between cellular compartments. In contrast to their comment that no similar extensions have been described in mitochondria, we would like to draw attention to previous research showing that such protuberances are also common to both mitochondria and peroxisomes in plants (Figure 1) ([4—7]; and see movies byProfessor Brian E.S. Gunning FRS available from http:// www.plantcellbiologyondvd.com). Indeed, such membranous extensions have been reported to be emanating from mitochondria in chick spinal cord [8], from hydrogeno-somes in trichomonad species [9] and from the apicoplasts of Sarcocystis, an apicomplexan parasite [10]. These membranous extensions are thus a feature common to endo-symbiosis-derived organelles and peroxisomes.
