Abstract

A variety of plants were colchicine treated to double their chromosome number. Chromosomes are genetic carriers that determine the individual traits of organisms. The doubling of chromosomes will lead to modifications in plant morphology, physiology and genetics. To determine the response of mulberry trees induced by colchicine, using mulberry variety Yu-711 leaves as research materials, two small RNA libraries (control and experimental groups) were constructed. It was found that 45 known miRNA genes and 78 predicted novel miRNA genes in the sequence results. A comparison of data between the control group and the experimental group revealed 37 differentially expressed miRNA genes, 19 genes of which were up-regulated and 18 genes of which were down-regulated. Eight miRNAs were selected from 37 differentially expressed miRNA genes. These miRNAs were verified by quantitative real-time PCR, and the expression levels of these miRNAs were found to be consistent with those obtained by sequencing, which proved the accuracy of sequencing results. The PsRNATarget software was used to predict the target genes of 8 miRNAs. The Gene Ontology and Kyoto Encycopedia of Genes and Genomes analysis were used to collect the functions of target genes and confirm that target genes are mainly involved in biological processes, cell components and molecular functions. novel-77 miRNA was selected from 37 differentially expressed miRNAs. What will serve as a fundamental data in understanding mulberry miRNAs function in molecular biology research and further provides the molecular mechanism of mulberry gene regulation as induced by colchicine is that the prediction of novel_77 precursor sequence and the target gene (XM_010104258.2), as well as the secondary structure analysis.
