Expanded gene families. A Expansion (red numbers) and contracted (blue numbers) gene families in different plants; “ + ” represents the number of gene families that have expanded on the node; and “−” represents the number of gene families that have contracted on the node. Black dots indicate a common ancestor. B Biosynthesis of the amino acid regulation pathway in the KEGG analysis of E. angustifolia
