  abstract = {{T}he rubber synthesis in latex cells requires sucrose. {T}hese particular cells are heterotrophic ones and are apoplastically connected to other tissues. {S}uch features imply that the rubber yield may depend on the latex cell efficiency to absorb and to use the imported sucrose. {T}his study investigates the sucrose transporters as key genes for rubber biosynthesis involved in the ethylene-stimulated rubber yield. {S}even putative sucrose transporters had been isolated from a latex-derived c{DNA} library of {PB} 217. {E}xpression profiling of these sucrose transporters under ethylene stimulation in {PB} 217 underlined the role of one sucrose transporter: {H}b{SUT}1{B} ({H}evea brasiliensis {S}ucrose {T}ransporter 6) ({D}usotoit-{C}oucaud et al., 2007). {T}his paper reports the next stage in {H}b{SUT}1{B}, molecular characterisation. {I}ts expression in different parts of the rubber tree was studied. {I}t was preferentially expressed in leaves and bark. {T}his result was completed by in-situ hybridisation experiments. {I}n addition, promoter cloning and analysis revealed some clues for the wounding regulation of {H}b{SUT}1{B}. {T}he {H}b{SUT}1{B} expression was analysed in response to different treatments in latex or bark tissues. {H}b{SUT}1{B} was considerably up-regulated by hormones and wounding in bark but not in latex. {T}his regulation appeared to be tissue-specific.},
