Sub-functionalization to ovule development following duplication of a floral organ identity gene.

Developmental biology - 1 Sept 2015

Galimba Kelsey D, Di Stilio Verónica S

Abstract excerpt

Gene duplications result in paralogs that may be maintained due to the gain of novel functions (neo-functionalization) or the partitioning of ancestral function (sub-functionalization). Plant genomes are especially prone to duplication; paralogs are particularly widespread in the floral MADS box transcription factors that control organ identity through the ABC model of flower development. C class genes establish...
