Ries, David; Holtgräwe, Daniela ; Viehöver, Prisca; Weisshaar, Bernd: Rapid gene identification in sugar beet using deep sequencing of DNA from phenotypic pools selected from breeding panels. In: BMC Genomics. Jg.17 H. 1. 2016
Inhalt
- Results and discussion
- Improvement of InDel detection
- Improvement of variant calling and variant filtering
- Identification of a 31 kbp interval containing the RED gene
- Identification of the causal gene from three genes in the interval
- The number of accessions used has a high influence on mapping resolution
- About 30 fold coverage is sufficient for interval detection
- Conclusions
- Methods
- Selection of plant material
- Plant growth and DNA isolation
- Library preparation and sequencing
