Electron microscopic studies show that the electron density of the mitochondria of the thermogenic appendix of Sauromatum guttatum inflorescences changes during development. Two to 3 days before heat-production, the mitochondria accumulate osmiophilic, electron-dense material between the inner and outer membranes. During heat-production and the release of volatiles compounds the osmiophilic material disappears from the inter membrane space. Deposits with the same electron density are also found in the endoplasmic reticulum. It is concluded that the mitochondria may also have the capacity to accumulate that material in the inter membrane space.
电子显微镜研究表明,魔芋花序产热附属器线粒体的电子密度在发育过程中会发生变化。在产热前两到三天,线粒体内外膜之间积累了嗜锇性、电子致密物质。在产热和挥发性化合物释放过程中,嗜锇性物质从膜间空间消失。在内质网中也发现了具有相同电子密度的沉积物。由此得出结论,线粒体也可能有能力在膜间空间积累该物质。
