Plant development: Two sides to organ asymmetry.
Three gene families have been identified which interact to polarize plant lateral organs. The results suggest that organ polarity is initially determined by a signal from the shoot tip which specifies adaxial organ identity and results in repression of abaxial identity, thereby aligning the polarity of organs with the stem.
