title: RNA-seq of leaves represent adult phasein Pyrus
design: Leaf samples were collected from three independent hybrid offsprings of Whangkeumbae and zaosu (Pyrus bretschneideri Rehd), Adu leaves were collected from the upper of the flower node of 6-year-old Pyrus trees and Juv leaves were collected from the basal part of the tree. To reduce the differences caused by leaf age, fully expanded leaves were collected. A total amount of 3 g RNA per sample was used as input material for the RNA sample preparations. And sequencing libraries were generated using NEBNext Ultra RNA Library Prep Kit for Illumina (NEB, USA).
