Schematic representation of the
Ubi-hut plasmid (6.0 kb) linearized at the unique
HindIII site showing the maize ubiquitin promoter
(Ubi prom.), exon 1 and intron 1 plus the
SrMV-SCH-untranslatable CP-coding region with 77 nucleotides of the 234
3′UTR sequence, and nos termination sequence (n) cloned
into pUC8. Restriction sites: E, EcoRI; H,
HindIII; Pst, PstI. Numerical values
indicate approximate kilobase pairs.
