Type	Gene number	Change after PEG-treatment
I	671	D↑R↑

II	260	D↑R-
	63	D↓R-
III	2	D↑R↓

D: uncapped mRNA abundance indicated by parallel analysis of RNA end tags; R: transcript abundance indicated by RNA-Seq reads. Genes with log₂ (fold change) ≥ 1 and a P-value < 0.001 were considered as up regulated genes and genes with log₂ (fold change) ≤ − 1 and a P-value < 0.001 were considered as down regulated genes. Genes with −1 < log₂ (fold change) < 1 and a P-value > 0.001 were designated as unchanged
