Hypocotyl elongation of near isogenic lines of the Sh1 locus under different light treatments. In A, the two NILs were grown under dark for 2 d, then moved to LDUVB or UVB-free lights or continued in the dark for 10 d. In B and C, the NILs were grown under either UVB-free WL (white light) or LDUVB light for 4 d, then moved to LDUVB and UVB-free WL, respectively. Hypocotyl length was measured every other day after switch the lights for 12 d. Each data point was the mean from three plants. The solid square, triangle, or circle represents NIL-LH, NIL-SH or both, respectively. Solid dark, purples, and dashed blue lines indicate dark, LDUVB, and UVB-free WL, respectively.
