Abbreviations:



Km Bacterial kanamycin resistance gene (also called kanR).
Cm Bacterial chloramphenicol resistance gene.
Hyg Plant hygromycin resistance gene.
Bar Gene encoding resistance to the herbicide BASTA.
OCS 3' Poly adenylation signal sequence from Agrobacterium tumefaciens.
MAS 3' Poly adenylation signal sequence from Agrobacterium tumefaciens.
MAS 1' Plant promoter from Agrobacterium tumefaciens .
CaMV 34S Viral promoter; our constructs have the omega leader of TMV (Gene 1987;60(2-3):217-25 ) at the end of the promoter sequence; this sequence is thought to increase translation efficiency, but it is not expected to influence RNAi.
LB T-DNA left border.
RB T-DNA right border.
GUS 360 base pair fragment from the GUS (Escherichia coli beta-glucuronidase gene).
ChsA intron 1,353 bp fragment from the petunia Chalcone synthase A gene.
