Comparative Transcriptome Analysis Provides New Insights into the Molecular Regulatory Mechanism of Adventitious Root Formation in Ramie (Boehmeria nivea L.).

ABSTRACT: The occurrence of adventitious roots is necessary for the survival of cuttings. In this study, comparative transcriptome analysis between two ramie (Boehmeria nivea L.) varieties with different adventitious root (AR) patterns was performed by mRNA-Seq before rooting (control, CK) and 10 days water-induced adventitious rooting (treatment, T) to reveal the regulatory mechanism of rooting. Characterization of the two ramie cultivars, Zhongzhu No 2 (Z2) and Huazhu No 4 (H4), indicated that Z2 had a high adventitious rooting rate but H4 had a low rooting rate. Twelve cDNA libraries of the two varieties were constructed, and a total of 26,723 genes were expressed. In the non-water culture condition, the number of the distinctive genes in H4 was 2.7 times of that in Z2, while in the water
