บทคัดย่อ (EN): The economic product of Hevea is a rubber-containing cytoplasm, which flows out from laticiferous cells upon bark tapping. It has been known for long that the natural rubber synthesis requires sucrose and that the laticiferous cells are heterotrophic, apoplastically connected to other tissues. These features imply that the rubber yield may depend upon the efficiency of laticiferous cells to load and to use the imported sucrose. Here, the sucrose transporters were investigated as part of a program aimed at identifying and studying major genes involved in the ethylene-stimulation of the rubber yield. First, seven putative sucrose transporters have been isolated from a late specific cDNA library. Based on their sequence homologies, they belong to three SUT families (SUT1, SUT2 and SUT4). Expression profiling of these sucrose transporters was monitored in the latex from trees of the PB217 and PB260 clones, using real time PCR. Our data show that they are differentially regulated by ethylene (3 are up regulated, 1 is down regulated and 3 insensitive to ethylene) and this regulation is tissue-specific. To give an insight into the mechanism by which ethylene regulates sucrose transporter expression, their promoters have been cloned and the haracterization of their respective activity is on the way in our laboratory.
