Boron-Mediated Plant Somatic Embryogenesis: A Provocative Model

Figure 2

A hypothetical model based on the results shown for the involvement of boron on plant somatic embryogenesis. The putative candidate genes and biological processes upregulated in response to boron supplementation are highlighted. The minimal and optimal supplies of boron activate different transcription factors, hormones, and other cellular proteins known to be responsible for the induction of embryogenic potential in the cell (see text for details).
