Setaria as a model system:
Setaria viridis is a C4 Panicoid grass with many favorable attributes for a model C4 genetic system including short stature, rapid lifecycle, high seed production and simple growth requirement (link to article). We are currently developing numerous resources to accelerate the adoption of this model plant.

Brachypodium distachyon is an excellent model organism for studying temperate grasses. In order to facilitate reverse genetics, we have created an EMS-mutagenized Bd21-3 TILLING population of ~ 5000 M2 families. TILLING (Targeting Induced Local Lesions IN Genomes) is an efficient technique to identify mutations in genes of interest through PCR-based screens of mutagenized populations. By integrating TILLING methods with Illumina sequencing of target gene amplicons, we have developed a High throughput protocol and informatics pipeline for efficiently identifying single base pair mutations among pools of mutant individuals. To date, we have screened for 67 SNPs in 6 target genes and 55 SNPs were confirmed as positive through Sanger sequencing thus providing a high efficiency of 82% on average. Currently, we are optimizing our method to minimize per gene cost.
If you are interested in obtaining mutants from this TILLING population, we would be happy to provide it for a service fee (to cover the cost). Please submit a request to Ying Rong (email@example.com).
