FIG. 4.

Classification based on Riley codes of genes differentially regulated (≥3-fold) during bacteroid development. Genes expressed only in early/intermediate bacteroids (7 days p.i.) are represented by black bars, and genes expressed only in mature bacteroids (≥15 days p.i.) are represented by unfilled bars. Genes expressed throughout bacteroid development are represented by gray bars. (A) Upregulated genes. (B) Downregulated genes. The functional classifications were derived from annotations available via RhizoDB.
