Research Areas

Whole genome analyses have become familiar along with innovations in the field of molecular biology. We have been using high-throughput DNA sequencing techniques such as next-generation sequence instruments to analyze gene mutations. LETmax mutants have become more and more useful and important in modern genetic studies, enabling the discovery of genes that control important traits, and revealing the functions and mechanisms underlying their operation. The discovery of genes using mutants may lead to emergence of a new field in biology, “mutagenomics”.
