R gene enrichment and Sequencing (RenSeq, Jupe et al. 2013) is a genome complexity reduction method which allows to enrich for nucleotide-binding, leucine reach repeat (NLR) type plant disease resistance genes prior to sequencing. RenSeq was established and successfully used with Illumina platforms (Jupe et al. 2013, Andolfo et al. 2014), however the repetitive nature of NLR genes hampered de novo assembly of this family. Here we describe a protocol which enables to prepare long enriched libraries that are suitable for Pacific Biosciences Single-Molecule Real Time (SMRT) sequencing. Reads Of Inserts (ROI) generated with this protocol are around 3-4 kb in length (longer than the average NLR sequence). These long reads are especially well suited for de novo assembly of whole NLR genes including their regulatory elements
