Regulation and evolution of the interaction of the seed B3 transcription factors with NF-Y subunits

In this review, we first summarize our current understanding of the role of each member in the network in the light of recent advances regarding their regulation and structure/function relationships. In a second part, we discuss new insights concerning the evolution of the LAFL genes to address the more specific question of the conservation of LEAFY COTYLEDONS 2 in both dicots and monocots and the putative origin of the network. Last we examine the current major limitations to current knowledge and future prospects to improve our understanding of this regulatory network.
