Potential Selection System for Mutants with Increased Lysine, Threonine, and Methionine in Cereal Crops1
- C. E. Green and
- R. L. Phillips2
Simultaneous addition of lysine and threonine inhibits growth in maize (Zea mays L.) callus cultures and embryo cultures from several cereals. Methionine or homoserine reverses lysine-threonine inhibition. Isolation of feedback inhibition resistance mutants is proposed for several cereals by selecting callus or seedlings which grow in the presence of lysine-threonine. Resulting mutants may be overproducers of lysine, threonine, or methionine.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
