Do mitochondria play a role in remodelling lace plant leaves during programmed cell death?
Results depicted mitochondrial dynamics in vivo as PCD progresses within the lace plant, and highlight the correlation of this organelle with other organelles during developmental PCD. To the best of our knowledge, this is the first report of mitochondria and chloroplasts moving on transvacuolar strands to form a ring structure surrounding the nucleus during developmental PCD. Also, for the first time, we have shown the feasibility for the use of CsA in a whole plant system. Overall, our findings implicate the mitochondria as playing a critical and early role in developmentally regulated PCD in the lace plant.
Diets high in fast foods, snacks, soft drinks, and meat were associated with relatively low concentrations of carotenoids and alpha-tocopherol. This pattern contained the largest number of participants, and could contribute to the extensive health disparities seen in this region.
