Fig. 2From: The PHOSPHATE1 genes participate in salt and Pi signaling pathways and play adaptive roles during soybean evolutionVariations in organ-specific expression of PHO1 gene family in wild and cultivated soybeans. a-e Expression variation of soybean PHO1 genes in Class I. f-i Expression variation of soybean PHO1 genes in Class II. G. max (Gm) includes five cultivars (SN14, HF, NF, HN, and DN), and G. soja (Gs) consists of five wild accessions (ZYD6, Y1, Y2, Y3, and Y4). The gene expressions in various tissues as indicated were analyzed, and the raw data are shown in Additional file 1: Figures S3 and S4Back to article page
