A single amino-acid change in the acetolactate synthase (ALS) protein of
tobacco confers resistance to the herbicide chlorsulfuron. A deleted,
nonfunctional fragment from the acetolactate synthase gene, carrying the
mutant site specifying chlorsulfuron resistance plus a closely linked novel
restriction site marker, was cloned into a binary vector. Tobacco
protoplasts transformed with Agrobacterium tumefaciens carrying this vector
yielded chlorsulfuron-resistant colonies. DNA gel blot analysis of DNA from
these colonies suggested that in three transformants homologous
recombination had occurred between the endogenous ALS gene and the deleted
ALS gene present in the incoming T-DNA. Plants were regenerated from these
chlorsulfuron-resistant colonies, and in two of the transformants, genetic
analysis of their progeny showed that the novel gene segregated as a single
Mendelian locus. Possible models for the generation of these recombinant
plants are discussed.
