Fig. 1From: Suppression of different classes of somatic mutations in Arabidopsis by vir gene-expressing Agrobacterium strainsConstructs for scoring somatic mutation rates. a. Construct for scoring point mutations, showing the positions and types of mutated bases in the open reading frame of the GUS gene, [32, 33]. b. Gene cassette with an inverted repeat of the truncated GUS gene [34]. c. Construct to detect frame-shift mutations [36]. d. Construct to score transposition frequency; the Tag1 element is engineered between the GUS and a CaMV 35S promoter [37]. e. A blue spot (arrow), showing functional GUS reversions after histochemical stainingBack to article page
