Methionine (Met) is an essential amino acid that is often unavailable at sufficient dietary levels. In order to better understand Met pathway regulation, a cDNA encoding cystathionine beta-lyase (CbL; EC 4.4.1.8) has been cloned from Solanum tuberosum. An antisense construct of this gene was used to generate transgenic potato plants with reduced CbL levels. Transgenic plants exhibiting leaf CbL activity levels of up to 50% below wild-type levels were obtained. Metabolite analysis revealed a… CONTINUE READING
