Arabitol dehydrogenase
A non-antibiotic marker for the selection of transgenic plants
Last modified 4 November 2006

	E. coli strain C and other related bacteria have the ability to use arabitol as the sole carbon source. The photo at left shows E. coli strains K12 (top row) and C (bottom row) growing on minimal medium with arabitol (left column) and LB (right column). The gene was isolated from E. coli C. The wildtype sequence is in GenBank as AF359520
	Photo at left shows a rice callus growing on arabitol-supplemented medium Best appears to be 0.25% sucrose and 2.75% arabitol Transformation frequencies are equivalent to those obtained with hygromycin as the selectable marker
	Germination of rice seedlings on medium supplemented with arabitol Left: Nontransgenic Right: T1 rice seedlings transgenic for atlD
