The fivefold discrepancy in size between the S. cerevisiae (84 kb) and mammalian (16.6 kb) mitochondrial genomes indicates the fact that there must be a great difference in their genetic organization in spite of their common function.

According to the current hypothesis, the gradient in phototropin phosphorylation induces the movement of auxin to the shaded side of the coleoptile. Once the auxin reaches the shaded side of the tip, it is transported basipetally to the elongation zone, where it stimulates cell elongation. The acceleration of growth on the shaded side and the slowing of growth on the illuminated side (differential growth) give rise to the curvature toward light.
