Summary of the expression of eye patterning genes in eye primordia of P. tepidariorum. (A) The studied genes distinguish the different eyes. Apart from general eye genes (blue), other genes mark the median eyes (orange) and the lateral eyes (green) and even distinguish the anterior lateral eyes (red). (B) The four eye pairs of spiders express their specific combinations of eye developmental genes. ALE, anterior lateral eyes; PLE, posterior lateral eyes; MLE, median lateral eyes; ME, median eyes.
