Abstract
from this pathway play a key role in plant development. From the miRNA-seq, the number of clean reads was ranging from 12,132,221 to 25,632,680. A total of 220 miRNAs were predicted in this study, and all of them were identified as novel miRNA. The top three candidate KEGG pathways of miRNA were ribosome signaling pathway (13 miRNAs), spliceosome pathway (13 miRNAs), and plant hormone signal transduction pathways (10 miRNAs). With the mRNA and miRNA integrated analysis, we found some key genes were regulated by some miRNAs. Among them, the scarecrow-like 6 protein can be up or down regulated by mir8, mir120, mir184, mir_214, mir125, and mir130. The function of Della protein was regulated by mir24, mir74, mir94, mir139, and mir190. This study contributes to understanding how heterosis regulates the traits, such as crop production, fruit weight, and fruit length.
