A high-throughput DNA extraction method from rice seeds

Rapid and inexpensive preparation of genomic DNA from rice seeds for marker-assisted selection and seed purity estimation is a major bottleneck for plant breeders. Here, we describe a high-throughput method that provides DNA at sufficient quantity and quality for these applications. Optimization of buffer composition and individual protocol stages allow processing of 384 samples within 2 h, yielding templates that reliably support downstream polymerase chain reaction of single copy amplicons up to 1.2 kb.
