Depositor Comments

Used to confirm activation-tagged genes. Contains multiple cloning sites adjacent to the same tetramerized CaMV 35S enhancers as in the activation-tagging vectors from this article.

Kanamycin gene for plant selection on MS media.

Plasmid selection in E. coli and in A. tumefaciens is spectinomycin (100 mg/l).

The four enhancer repeats in the construct may be unstable in E. coli and Agrobacterium if stored at +4'C for extended time. Check by PCR with T7 (or M13-20) oligo and this one derived from the RB sequence: 5' acc cgc caa tat atc ctg 3'. This should give 1.4 kb band. Note that these oligos will not work in a transgenic plant, as the RB sequence is not transfered. Using this test, we found that after 1-2 weeks in a fridge the Agrobacterium strain loses on average one copy of a repeat, and after a month in a fridge there is only one copy left. It is a good idea to use a freshly streaked colony from a good -70'C glycerol stock for every infiltration.
