Project description:Genome-wide studies in plants have provided evidence for the role of H3K9ac and H3K27me3 in gene activation and repression, respectively. The roles of these histone modifications in rose remain unknown and represent a represent a limitation to the full understanding of how thousands of bioprocesses are regulated. To determine the genomic landscape of these marks, we performed a ChIP-seq analysis using H3K9ac and H3K27me3 antibodies on petals from a heterozygous plant.

Project description:MicroRNAs (miRNAs) are small non-coding RNAs that play important roles by regulating other genes. Rose, Rosa rugosa Thunb., is an important ornamental and edible plant, yet there are only a few studies on the miRNAs and their functions in rose. Here we carried out computational and experimental analysis of miRNAs, phased small interfering RNAs (phasiRNAs) and mRNAs in rose by analyzing 10 small RNA sequencing profiles from roots, petals, pollens, stamens, and leaves and 4 RNA-seq profiles in leaves and petals of rose. To identify the targets of miRNAs and phasiRNAs, we produced a degradome profile for rose leaf which is analyzed using the SeqTar algorithm. This study identified 25 conserved pre-miRNAs, of which 24 have not been reported previously. We also found 22 novel pre-miRNAs. Three hundred and thirty nine 21 nucleotide (nt) PHAS loci, and forty nine 24 nt PHAS loci were also identified. We identified more than 19,000 putative targets of the conserved miRNAs/tasiRNAs using a criteria of less than 4 mismatches between miRNA and targets. Among these targets, 592 have shown significant accumulation of degradome reads. Our results demonstrate that the miR482 family triggers the generations of phasiRNAs by targeting nucleotide-binding, leucine-rich repeat (NB-LRR) disease resistance genes in rose. Our results also suggest that the deregulated genes in leaves and petals are significantly enriched in GO and KEGG pathways related to metabolic processes and photosynthesis. These results significantly enhanced our knowledge of the miRNAs and phasiRNAs, as well as their potential functions in rose.

Project description:MicroRNAs (miRNAs) are small non-coding RNAs that regulate target mRNAs by inducing degradation or preventing translation of their target mRNAs.

Here we carried out computational and experimental analysis of miRNAs and phased small interfering RNAs (phasiRNAs) in rose by analyzing 10 small RNA profiles from roots, petals, pollens, stamens, and leaves. To identify the targets of miRNAs and phasiRNAs, we generated a degradome profile for rose leaf which is analyzed using the SeqTar algorithm. This study identified 25 conserved pre-miRNAs, of which 24 have not been reported previously. We also found 22 novel pre-miRNAs. Three hundred and thirty nine 21 nucleotide (nt) PHAS loci, and forty nine 24 nt PHAS loci were also identified. We identified more than 4000 putative targets of the conserved miRNAs using a criteria of less than 4 mismatches between miRNA and targets. Among these targets, at least 171 have shown significant accumulation of degradome reads. Our results demonstrate that the miR482 family triggers the generations of phasiRNAs by targeting nucleotide-binding, leucine-rich repeat (NB-LRR) disease resistance genes in rose. These results significantly enhanced our knowledge of the miRNAs and phasiRNAs, as well as their potential functions in rose.

Project description:The Barcelona Robertsonian system (BRbS) presents mice with standard karyotype (diploid number 40) but also carrying Robertsonian fusions (ehich lead to variable diploid numbers ranging from 28 to 39). To study the heterogeneity of their genetic background and possible genome divergence between them, samples from three populations were genotyped.
