    • Figure 1.  Conservation of miRNAs in fruits. MIRNA families among 46 fruit species, most of which are included in the database repository-sRNAanno[18] with six fruit species appended based on the newly released data[1924]. The tree diagram on the left shows the general evolutionary relationship of the fruit species. Boxes are highlighted if a MIRNA family has been identified in the fruit species via sequencing or annotated based on its genome sequence. Groups of MIRNA families are highlighted in different colors according to the degree of conservation. Fruit species lacking a MIRNA family or with uncertain identification are left blank. The bar graph on the right shows the number of miRNA loci in each fruit species.
