A Chimeric Soybean Plant

摘要

The Chimaera of Greek mythology was a 'fire-breathing monster, the foreparts of whose body were those of a lion, the middle parts those of a goat, and hinder parts those of a dragon.' (Neilson-Jones, 1969). The occurrence of plant chimeras in nature is a common phenomenon. Chimeras are a direct result of the segregation of normal and mutant organelles into genotypically and phenotypically distinct vegetative sectors. Progeny of chimeric plants manifest a direct relationship between sector phenotypesand nuclear or cytoplasmic genotypes.
