In any adult eye, all ommatidia in the dorsal half are of one chiral form while those in the ventral region are all of the other. When ommatidia are first formed they are symmetric structures3 (achiral; which we color-code as black), and as they develop they acquire asymmetry, adopting...
Pollen coat proteins (PCPs) are cysteine-rich small-molecule proteins, which exhibit high levels of polymorphism and are expressed in gametocytes. Previous investigations have revealed that PCP genes are involved in pollen wall synthesis, pollen-stigma r
