Apomictic

The adjectival form of apomixis. Apomixis

Greek: apo = without; mixis = mixing. Asexual reproduction by seeds produced from the maternal tissue of a flower. Apomictic seeds occur mainly in grasses, and they have the advantage of being the equivalent of vegetative propagation, being free of most vegetatively transmitted diseases (particularly viruses). The so-called 'apomictic gene' is a topic of interest among molecular biologists because it could very easily preserve agricultural characteristics, including hybrid vigour, in heterozygous seeds of open-pollinated crops. Apothecium

An open fruiting body shaped like a 'dry martini' glass, produced by some Ascomycetes, with asci on the open, upper surface. Sometimes called 'cup fungi'.
