A sugar beet chlorophyll a/b binding protein promoter void of G-box like elements confers strong and leaf specific reporter gene expression in transgenic sugar beet

Table 2 Transient gene expression analysis of two CAB promoters in sugar beet leaves. The plasmids harbor promoter fragments of cab11 (pC1L) and cab12 (pC2L).

Promoter Reporter Gene Construct^a	Relative expression level in sugar beet leaves^b
pC1L-7126	7.0 +/- 3.4^c
pC1L-1097	9.6 +/- 4.6
pC2L-2998	8.0 +/- 0.2
pC2L-1827	4.5 +/- 0
pC2L-989	6.4 +/- 2.4
pC2L-342	6.5 +/- 1.9
CaMV 35S	30.2 +/- 16.6

^aThe number following the identifier of the promoter relates to fragment length
^bThe relative expression level was calculated as:
(Photinus value_(construct) - Photinus value _{(without DNA)} / Renilla value _(construct) - Renilla value _{(without DNA)}) × 100.
^cAverage of at least three assays +/- standard deviation
