 ## Test diurnal gene expression of circadian clock and flowering time genes in Bowman and Bowman-derived introgression lines.
 
-2-week old plants from the genotypes BW, BW(Ppd-H1), BW(eam7), and BW(Ppd-H1,eam7) were sampled at Zeitgeber Time (ZT) 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22.
+2-week old plants from the genotypes BW, BW(*Ppd-H1*), BW(*eam7*), and BW(*Ppd-H1,eam7*) were sampled at Zeitgeber Time (ZT) 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22.
 
-Gene expression of CO1, ELF3, FT1, GI, LHY, LUX1, LWD1, PHYB, PHYC, Ppd-H1, PRR1, PRR59, PRR73, PRR95 and VRN1 were tested.
+Gene expression of *CO1, ELF3, FT1, GI, LHY, LUX1, LWD1, PHYB, PHYC, Ppd-H1, PRR1, PRR59, PRR73, PRR95* and *VRN1* were tested.
