In addition, we anticipate that more genetic screens will be performed to identify the Rho1-interacting genes playing critical roles at other stages of development such as during gastrulation, segment groove formation and head involution during embryogenesis.
On the basis of these pioneering experiments, and the recent demonstration that Drosophila can be used to identify the core regulatory network that contributes to the development of AML (Osman et al., 2009; Sinenko et al., 2010), it is expected that more genetic screens performed in flies will provide novel entries to the study of acute and chronic leukaemias in mammals.
The company recently launched a test for hereditary high cholesterol as an indication for possible heart disease and says it plans to release more genetic health screening kits in the future.
As more components of the plant small RNA machinery are identified by more intricate genetic screens and biochemical methods, the relationship and divergence between plant species and lineages will increasingly be an area of interest.
In summary, we think that in addition to the approach of screening for stress tolerance among diverse rice genotypes (including wild relatives), there are many benefits to be gained from developing an approach to root biology based on the integration of our knowledge of the physiology of plant response to stress to define ideotypes that can form the basis of new more specific genetic screens.
Forward chemical genetics involves screening a library of compounds to find small molecules that generate a consistent phenotype in a biological assay, analogous to more traditional genetic screens.
However, using this system and others like it, it will be possible to conduct more extensive genetic screens for mutations that influence compensatory growth or regeneration.
More recent genetic screens have identified transcription factors DMRT1 and ATF7IP, as well as the telomere regulator TERT, as susceptibility genes for TGCTs.
More recently, this genetic screening approach has been applied to mammalian cell systems using different forms of RNAi libraries.
Recent technological advances in DNA sequencing have enabled more comprehensive approaches for genetic screening [ 38– 40].
