Allelic variation at a major QTL for cell wall related traits and coordinated changes in gene expression in maize

ngs2015_12_zeawall2-zeawall2-Address the hypothesis that allelic variation at a major QTL for cell wall related traits gives rise to coordinated changes in gene expression in maize-Two pairs of BC2S2 maize lines carrying F271 or F288 alleles in an 18-20 Mb interval of chromosome 6 in an otherwise F271 genetic background were grown in the field at Mauguio (Hérault, France) in 2015 with two row replicates. Irrigation was applied during the summer to prevent water stress. The bottom third of upstream-ear internodes (without nodes) of three representative plants in each of the two replicates were harvested two days before silking. All samples were immediately frozen in liquid nitrogen and stored at -80°C. 10 samples with 2 biological replicates. allele,genomic comparison
