Identification of MicroRNAs Related to Phytohormone Signal Transduction and Self-incompatibility of Rabbiteye Blueberry Pollen

MicroRNAs (miRNAs) related to phytohormone signal transduction and self-incompatibility may play an important role in the xenia effect. However, associated research this area is still lacking rabbiteye blueberry ( Vaccinium ashei ). In study, we identified miRNAs, predicted their target genes, performed functional enrichment analysis of screened for miRNAs signaling self-incompatibility. A total 491 were identified, which 27 67 known as well 274 416 new found cultivars Brightwell Premier, respectively. Compared with ‘Premier’, 31 upregulated 62 downregulated ‘Brightwell’. Kyoto Encyclopedia Genes Genomes (KEGG) indicated that 4985 genes involved biosynthesis amino acids, plant–pathogen interaction, spliceosome pathways. 10, one, five, two, two candidate auxin, cytokinin, gibberellin, abscisic acid, ethylene, brassinosteroid, salicylic acid signaling, respectively, pollen identified. Further novel_miR_49 was a miRNA self-incompatibility, gene maker-VaccDscaff21-snap-gene-21.37 . addition, KEGG showed they ribosome, aminoacyl-tRNA biosynthesis, glycosylphosphatidylinositol-anchor The results revealed microRNAs regulated based on signaling. Results suggest more effects regulation hormone necessary elucidating molecular mechanism
