Predicted SSRs (genomic)Publication: Staton M, Best T, Khodwekar S, Owusu S, Xu T, Xu Y, Jennings T, Cronn R, Arumuganathan AK, Coggeshall M, Gailing O. Preliminary Genomic Characterization of Ten Hardwood Tree Species from Multiplexed Low Coverage Whole Genome Sequencing. PloS one. 2015 Dec 23;10(12):e0145031.
In order to develop SSR resources for ten important North American hardwood tree species, we individually barcoded and multiplex sequenced DNA from ten hardwood forest tree species using short reads produced from an Illumina HiSeq. Raw reads can be downloaded from the NCBI short read archive, project SRP021923. Bioinformatic processing included trimming, assembly, SSR identification and primer design, processing details including scripts are available.
Mapping PopulationLocations: University of Tennessee, Ames Plantation in Ames, TN and East Tennessee State Nursery Principal Investigators: Scott Schlarbaum (University of Tennessee), Oliver Gailing (Michigan Tech)
A honeylocust half sibling population has been established at the East Tennessee State Nursery and includes approximately 226 surviving individuals. Seeds were collected from a mother tree from Butternut Valley to develop this population. The population is being maintained by the UT Tree Improvement Program.
Parental analysis at Michigan Tech University identified 149 full siblings from this population. Additional seeds were collected from the mother tree for possible later population expansion. Transfer of the honeylocust full-sibling population from the East Tennessee State Nursery to the East Tennessee Research and Education Center in Knoxville was conducted to better maintain the population for future use. This was possible due to the relatively low number of full siblings (<100 trees) and small size of the seedlings.
Genotyping by sequencing is currently ongoing for a subset of this population with the aim to produce a genetic map. The genotypes will be posted when publicly available.
