"Imagine you’re a flower bud. You are blind, deaf, and dumb, but somehow you know how to create beautiful artwork. Through your efforts, a lovely rose, petunia or orchid will result. How would you do it? An article on Live Science suggests an amazing, though partial, answer: the bud has a map of
the finished product. “The shape of a flower’s petals and leaves are dictated by a biological map hidden inside the flower’s growing bud,” according to a new study from the John Innes Centre and the University of East Anglia, both in the UK.
They discovered that concealed maps within the flower buds are made up of patterns of arrows that act as instructions for how each cell in the bud should grow. As such, the maps essentially influence a flower bud’s cell polarity, or the functions of the cells.
The “arrows” are made up of proteins called PIN proteins that migrate to the tips of cells. When they concentrate, a pointed leaf results. When they fan out, a rounded shape, like a flower petal results. Other proteins follow the “arrows” to cause growth in those areas. PLoS Biology discussed the paper in a little more detail. The original paper in PLoS Biology described how the growth proteins follow the “polarity field” set up by the PIN proteins." CEH
Consider the lilies how they grow: they toil not, they spin not; and yet I say unto you, that Solomon in all his glory was not arrayed like one of these.
