title: RNA-seq of maize: K55_HN_Root_rep2
design: With the sufficient inorganic nitrogen input in the maize breeding process, our hypothesis is the response to nitrogen stress between New-Era, and Old-Era inbreds were changed. Two Old-Era inbreds (K55 and W153R) and two New-Era inbreds (SD40 and B73) planted in the growth chamber were used for RNA-seq.
