Genome-Wide Analysis of the miRNA-mRNAs Network Involved in Cold Tolerance in Populus simonii × P. nigra.

ABSTRACT:

Background

Cold tolerance is important for plants' geographical distribution and survival in extreme seasonal variations of climate. However, Populus simonii × P. nigra shows wide adaptability and strong cold resistance. Transcriptional and post-transcriptional regulation of cold-responsive genes is crucial for cold tolerance in plants. To understand the roles of regulatory RNAs under cold induction in Populus simonii × P. nigra, we constructed cDNA and small RNA libraries from leaf buds treated or not with -4 °C for 8 h for analysis.

Results

Through high-throughput sequencing and differential expression analysis, 61 miRNAs and 1229 DEGs were identified under cold induction condition in Populus simonii × P. nigra. The result showed t
