ABC model - permalink - collapse

All > Science > Biotechnology and Genetics > Food Biotechnology

Widely accepted model of flower organ identity that appears generally applicable to distantly related dicotyledon ous, although less well to monocotyledon ous plants. The model incorporates the Arabidopsis genes required for flower organ identity.
