Abstract: A method for the rapid isolation and identification of the DNA sequence of transposable element-tagged genes is provided. The method comprises a modified AFLP approach using a transposable element-anchored amplification to identify and clone an amplification product that is associated with a mutant phenotype. Once cloned, the amplification product of interest may be used to screen a cDNA library directly or may be sequenced and compared to available databases for sequence homology. A modification of this approach provides a method for the identification of the location of an additional type of insertion event into genomic DNA, more specifically transgene insertion into the genome of a host organism.

Abstract: Nucleotide sequences are isolated from Arabidopsis thaliana that code for proteins essential for plant growth and development. The essentially of the proteins may be exploited by recombinantly expressing the proteins and using them in screening assays to identify compounds that interact with or inhibit the proteins and are therefore potential herbicides.
