Background
Mango is a major tropical fruit in the world and is known as the king of fruits because of its flavour, aroma, taste, and nutritional values. Moreover, various parts of mango trees have been used for medical purposes. Although various regulatory roles of miRNAs and lncRNAs have been investigated in many plants, there is yet an absence of study in mango. This is the first study to provide information on ncRNAs of mango with the aim of identifying miRNAs and lncRNAs of mango and discovering of their potential functions by the interaction prediction of the miRNAs, lncRNAs and their target genes.
Results
In this analysis, 104 miRNAs and 7,610 temperature responsive lncRNAs were identified and the target genes of these ncRNAs were characterized. By analysing the interaction of miRNAs and their target genes, it was observed that miRNAs are mainly involved in growth, development, and stress responses of mango. For the lncRNAs, cold responsive lncRNAs bound to low temperature responsive proteins expressed at low temperature stress. GO enrichment analysis of heat and cold responsive lncRNAs revealed that they involved in all three basic processes; biological process, cellular component, and molecular function. Moreover, mango lncRNAs can target miRNAs to reduce the stability of lncRNAs and can function as molecular decoys or sponges of miRNAs.
Conclusion
This paper would provide the new information about miRNAs and lncRNAs of mango and would help for the further investigation of mango ncRNAs.
