RNA-seq of leaves represent juvenile phase in Pyrus
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).
