Abstract
The use of fluorescent nanomaterials with good photostability and biocompatibility in live imaging of cells has gained increased attention. Even though several imaging techniques have been reported for mammalian cells, very limited literatures are available for nanomaterial based live imaging in plant system. We studied the uptake ability of two different nanomaterials, the highly photostable CdSe quantum dots and highly biocompatible FITC-labeled silica nanoparticles by rice seedlings which could provide greater opportunities for developing novel in vivo imaging techniques in plants. The effects of these nanomaterials on rice seed germination have also been studied for analyzing their phytotoxic effects on plants. We observed good germination of seeds in the presence of FITC-labeled silica nanoparticles whereas germination was arrested with quantum dots. The uptake of both the nanomaterials has been observed with rice seedlings, which calls for more research for recommending their safe use as biolabels in plants.
