Plasmid construction
The sequences of two FYVE domains from the mouse
Hrs protein were connected with the linker sequence
QGQGS and fused to the N-terminus of enhanced green
fluorescent protein (plasmid pEGFP-C3 from Clontech)
as described before (Gillooly et al., 2000). This gene
construct was cloned into the binary vector pBLTI221,
thereby putting its expression under the control of the
CaMV 35S promotor. For DsRedT4 (Bevis and Glick,
2002) tagging the tandem FYVE domain was PCRamplified and cloned in frame with DsRedT4 within the
vector pRTL2 under the control of the CaMV 35S
promotor. The coding sequence for ARA6-GFP under
control of the Cauliflower mosaic virus 35S promoter
and nopaline synthase terminator (Ueda et al., 2001)
was excised with HindIII and EcoRI and was
inserted into the corresponding sites of pBI121
(Clontech). The resulting vector was introduced into
Agrobacterium tumefaciensstrain C58C1. AtRabF2a
cDNAwas amplified using the primers RabF2a
forward (5

-CGGGATCCATGGCTACGTCTGGAAACAAGA-30
) and RabF2a reverse (5

-GCTCTAGACTAAGCACAACACGATGAACTC-3

), and inserted
into a modified pCAMBIA expression vector with
eYFP at the N-terminus under the control of the 35S
CaMV promoter.
