Background Flowering is a crucial stage during plant development. To complement our RNA-seq analysis and investigate differences in protein abundance in not4a vs WT in more detail, we carried out a quantitative proteomics analysis of total protein extracts from. The comparative analysis of Arabidopsis RNA-seq is shown in Figure S3. In this study, we performed fluorescent protein-based imaging and tissue-specific RNA-seq analysis in Arabidopsis hydathodes. 5 μg of total RNA was treated with Turbo DNaseI (Ambion) to remove any genomic DNA. Mol Plant. In comparison with the EST data that provided the bulk of the TAIR10 annotation, the RNA-Seq data offer single-base resolution and more precise measurement of levels of transcripts and their isoforms (Wang et al. PLoS One 10,. Abstract Small RNAs (sRNAs) play a wide range of important roles in plants, from maintaining genome stability and enhancing disease resistance to regulating developmental processes. RNA-seq analysis: The bowtie2 version 2. Here we show that m 6 A. The most appreciable effects were found for heat stress, which induces a global reduction in splicing and editing efficiency. Fig. The resulting ribosome-protected RNA fragments (or ribosome foot-prints) are used to generate a sequencing library (Ribo-seq) (Fig. Published RNA-seq data sets were analysed and described previously (Borg et al. In the central cell of tetraploid plants, DEMETER (DME) is upregulated, which.
