Project description:To uncover the involvement of miRNAs and siRNAs in somatic embryogenesis of the perennial woody crop citrus, we carried out high-throughput (Illumina) sequencing (HTS) of sRNAs and RNA degradome tags in non-embryogenic and embryogenic tissue of Valencia sweet orange. A total of 191 stem-loop structures were identified, emanating 50 known and 45 novel miRNAs, 130 miniature inverted-repeat transposable elements (MITEs) derived small interfering RNAs (siRNAs) and 94 other siRNAs. Combining with the result of degradome sequencing, a total of 235 phased siRNAs (phasiRNAs), and 195 cleaved target genes were identified for miRNAs/siRNAs.

Project description:Small RNAs (21-24 nt) are pivotal regulators of gene expression that guide both transcriptional and post-transcriptional silencing mechanisms in diverse eukaryotes, including most if not all plants. MicroRNAs (miRNAs) and short interfering RNAs (siRNAs) are the two major types, both of which have a demonstrated and important role in plant development, stress responses and pathogen resistance. In this work, we used a deep sequencing approach (Sequencing-By-Synthesis, or SBS) to develop sequence resources of small RNAs from Citrus sinensis tissues (including leaves, flowers and fruit). The high depth of the resulting datasets enabled us to examine in detail critical small RNA features, such as size distribution, tissue-specific regulation and sequence conservation between different organs in this species. We also developed database resources and a dedicated website (http://smallrna.udel.edu/) with computational tools for allowing other users to identify new miRNAs or siRNAs involved in specific regulatory pathways, verify the degree of conservation of these sequences in other plant species and map small RNAs on genes or larger regions of the maize genome under study.

Small RNA libraries were derived from leaves, flowers and fruit of Citrus sinensis. Total RNA was isolated using the TriReagent (Molecular Research Center) for leaves and flowers and the Guanidinium-free for fruits, and submitted to Illumina (Hayward, CA, http://www.illumina.com) for small RNA library construction using approaches described in (Lu et al., 2007) with minor modifications. The small RNA libraries were sequenced with the Sequencing-By-Synthesis (SBS) technology by Illumina. PERL scripts were designed to remove the adapter sequences and determine the abundance of each distinct small RNA. We thank Erik Mirkov for providing the plant material, as well as Kan Nobuta and Gayathri Mahalingam for assistance with the computational methods.

Project description:To excavate the underlying molecular regulation network that during citrus fruit development and ripening, we used RNA-seq to generate high-resolution profiles of global gene expression in four different fruit tissues at six development stages. Using weighted gene coexpression network analysis, we identified modules of coexpressed genes and hub genes of tissue-specific networks. In general, this study was aimed to uncover the new molecular insights into citrus fruit development and ripening, and to reveal the specific nonclimacteric characteristics of citrus fruit.

Project description:Somatic embryogenesis in nucellar tissues is widely recognized to induce polyembryony in major citrus varieties such as sweet oranges, satsuma mandarins and lemons. This capability for apomixis is attractive in agricultural production systems using hybrid seeds, and many studies have been performed to elucidate the molecular mechanisms of various types of apomixis. To identify the gene responsible for somatic embryogenesis in citrus, a custom oligo-DNA microarray including predicted genes in the citrus polyembryonic locus was used to compare the expression profiles in reproductive tissues between monoembryonic and polyembryonic varieties. The full length of CitRKD1, which was identified as a candidate gene responsible for citrus somatic embryogenesis, was isolated from satsuma mandarin and its molecular function was investigated using transgenic ‘Hamlin’ sweet orange by antisense-overexpression. The candidate gene CitRKD1, predominantly transcribed in reproductive tissues of polyembryonic varieties, is a member of the plant RWP-RK domain proteins. CitRKD1 of satsuma mandarin comprised two alleles (CitRKD1-mg1 and CitRKD1-mg2) at the polyembryonic locus controlling embryony type (mono/polyembryony) that were structurally divided into two types with or without a miniature inverted-repeat transposable element (MITE)-like insertion in the upstream region. CitRKD1-mg2 with the MITE insertion was the predominant transcript in flowers and young fruits where somatic embryogenesis of nucellar cells occurred. Loss of CitRKD1 function by antisense-overexpression abolished somatic embryogenesis in transgenic sweet orange and the transgenic T1 plants were confirmed to derive from zygotic embryos produced by self-pollination by DNA diagnosis. Genotyping PCR analysis of 95 citrus traditional and breeding varieties revealed that the CitRKD1 allele with the MITE insertion (polyembryonic allele) was dominant and major citrus varieties with the polyembryonic allele produced polyembryonic seeds.
