The RACK 1-dependent miRNA pathway is involved in the regulation of plant chlorophyll biosynthesis
In order to further explore the crucial roles of receptor of activated C kinase 1(RACK 1) in the regulation of microRNA (miRNA) biogenesis and its target genes in higher plants, we systematically reanalyzed and uncovered small RNA sequence data of the <i>Arabidopsis rack 1</i> mutants wi...

| Summary: | In order to further explore the crucial roles of receptor of activated C kinase 1(RACK 1) in the regulation of microRNA (miRNA) biogenesis and its target genes in higher plants, we systematically reanalyzed and uncovered small RNA sequence data of the <i>Arabidopsis rack 1</i> mutants with the Gene Expression Omnibus(GEO) database that were available on the National Center for Biotechnology Information (NCBI) website. Nineteen novel miRNAs were identified. By resolving the differential expression of identified miRNAs, we identified HEMA and HEMB1, which are essential for the chlorophyll synthesis. This study provides a key theoretical basis for in-depth and systematic investigating the mechanism of RACK1 in the regulation of chloroplast development and photosynthesis. Our research also provides useful ideas and strategy for other researchers to explore potential data and information by using the public and shared databases. |
