Description
Four major QTL explaining lignin content and cell wall degradability variation have been identified in the F288 x F271 RIL progeny (Roussel et al., 2002, Maydica 47: 9-20). Gene expression has been considered as a way in identification of candidate gene underlying QTL. Five lines chosen for their allelic pattern at four main QTL were considered for expression studies, two lines with all four favorable alleles (RIL99, RIL54), two lines with the unfavorable allele at bin 6.06 QTL position (RIL39 , RIL71), and one line with the unfavorable allele at bin 9.02 QTL position (RIL118). Expression studies will be investigated in ear internode at two stages (emerging tassel and early silking).
Data processing
The data were normalized with the gcrma algorithm (Irizarry et al., 2003), available in the Bioconductor package (Gentleman and Carey, 2002).
