Genetic separation of autonomous endosperm formation (AutE) from the two other components of apomixis in Hieracium.

Plant reproduction - 1 Jun 2013

Ogawa Daisuke, Johnson Susan D, Henderson Steven T, Koltunow Anna M G

Abstract excerpt

In apomictic Hieracium subgenus Pilosella species, embryo sacs develop in ovules without meiosis. Embryo and endosperm formation then occur without fertilization, producing seeds with a maternal genotype encased in a fruit (achene). Genetic analyses in H. praealtum indicate a dominant locus (LOA) controls meiotic avoidance, and another dominant locus (LOP) controls both fertilization-independent embryogenesis and...
