Abstract
Plant genomes harbor dozens to hundreds of nucleotide-binding site-leucine-rich repeat (NBS-LRR, NBS for short) type disease resistance genes (Shao et al., 2014; Zhang et al., 2015). Proper regulation of these genes is important for normal growth of plants by reducing unnecessary fitness costs in the absence of pathogen infection. Recent studies have revealed that microRNAs are involved in regulation of NBS genes in plants (Zhai et al., 2011; Shivaprasad et al., 2012). This protocol describes computational methods for the genome-wide identification of plant NBS genes potentially regulated by microRNAs.
Equipment
- Personal computer (an internet connection is needed) (Intel Core i5-2300 CPU, 8 GB RAM)
Sequence data and software
- Sequence data compilation
The coding sequence (CDS) and protein sequences of interested genomes should be downloaded from relevant databases. A recommended database containing a relatively large number of sequenced plant genomes is Phytozome (http://www.phytozome.org/) (Goodstein et al., 2012). MicroRNAs of interested genomes can be retrieved from the miRBase (http://www.mirbase.org/) (Kozomara and Griffiths-Jones, 2014) or from in-house sequenced data. - Required software and online tools
The following software should be locally installed in your computer:- Hmmer 3.0 (http://hmmer.janelia.org/) (Johnson et al., 2010), for perform local hidden Markov models (HMM) search of NBS homologous proteins.
- NCBI BLAST+ or NCBI BLAST (http://blast.ncbi.nlm.nih.gov/Blast.cgi), for perform local blastp search of NBS homologous proteins.
- ActivePerl 5.14.2 (http://www.activestate.com/activeperl/downloads), for running scripts written in perl language.
- The online tools to be used are:
- COILS (http://www.ch.embnet.org/software/COILS_form.html) (Lupas et al., 1991), a program for identification of coiled-coils (CC) domain in protein sequences.
- Pfam (http://pfam. sanger.ac.uk/) (Finn et al., 2014), a database for identification of protein domains.
- psRNATarget (http://plantgrn.noble.org/psRNATarget/) (Dai and Zhao, 2011), a website designed for prediction microRNA targets in plants.
- Hmmer 3.0 (http://hmmer.janelia.org/) (Johnson et al., 2010), for perform local hidden Markov models (HMM) search of NBS homologous proteins.
