title: root RNA-seq of Rosa rugosaCK
design: Approximately 1 g of tender roots from each plant of the control group (CK) received 100% P (0.092 g NH4H2PO4). The HA1 group received 60% P + HA (0.0552 g NH4H2PO4 + 0.0368 g HA, equivalent to 40% P). The HA2 group received 40% P + HA (0.0368 g NH4H2PO4 + 0.0552 g HA, equivalent to 60% P).
