Gene expression levels of SGF14c (Glyma05g29080; black bars) and SGF14l (Glyma08g12220; gray bars) from different soybean tissues. The expression of genes was quantified by ultra-high-throughput sequencing after normalization of the read number by the total number of soybean reads (Libault et al., 2010a). Nine different soybean tissues (root hair, nodule, shoot apical meristem, flower, green pod, leaf, root, root tip, and stripped root) were used (Libault et al., 2010a). HAS, Hours after sowing; RH, root hairs inoculated (IN) and mock-inoculated (UN) with B. japonicum at 12, 24, and 48 h after inoculation.
