| Research Abstract |
This project aimed at uncovering the machineries (organelles) involved in thermogenesis in plants. To this end, we examined the gene expression landscape of skunk cabbage (Symplocarpus renifolius) during thermogenic and post-thermogenic stages. In-depth analysis suggested that cellular respiration and mitochondrial functions are significantly enhanced during the thermogenic stage. In contrast, genes involved in stress responses and protein degradation were significantly up-regulated during post-thermogenic stages. These data suggest that mitochondria may play key roles in plant thermogenesis.
