Quantum Dots Research Leads to New Knowledge about Protein Binding in Plants

n tube adhesion protein. This labeled the protein molecules with fluorescent tags. Quantum dots are much more resistant to photobleaching than conventional fluorescent markers and their small size make them ideal for biological imaging. The researchers then added the molecules to germinated lily pollen grains and examined them under a confocal microscope. This is the very first time that Quantum Dots have been utilized for live imaging in plant systems. The study opens the door for the potential use of Quantum Dots in live imaging of plant cells and provides valuable understanding of the mechanism of interaction between the pollen tube and female tissue during reproduction. “Integrating materials science, chemistry and plant biology to understand how and where specific proteins act on a pollen tube is one more step towards a better understanding of the fundamental processes involved, namely the network of the signaling process in plant reproduction,?said Ozkan. "A better understanding of the interaction of SCA with pollen tubes could help with successful plant breeding?
