Comparison of amino acid supply mechanisms between natural and nematode-induced sink tissues in Arabidopsis
Description:
We want to identify amino acid transporters that supply sink tissues of Arabidopsis thaliana with essential amino acids. For this purpose we will use plants, which are impaired in the synthesis of lysine or branched chain amino acids in the developing seed, an endogenous sink tissue, and giant cells induced by root-knot nematodes, an induced sink tissue. Microarrays will be used to identify transporters that are induced to compensate for the reduced synthesis of these amino acids. The transporters will be characterized in detail to gain knowledge about the mechanisms that supply sink tissues with essential amino acids. We will also investigate the influence of altered levels of lysine or branched chain amino acids on seed and nematode development.
