Development of electron microscopy atlas: Fusion with omics and electron microscopic data

Transmission electron microscopy (TEM) is important for high-resolution ultrastructure observation for organelles, cell and tissues. However, it is unsuitable for comprehensive analyses. I constructed TEM atlas to achieve an exhaustive ultrastructural analysis of organelles in model plants by using high-pressure freezing (HFP) and TEM techniques. To take wide and high-resolution TEM pictures, Arabidopsis roots and BY2 cells were frozen by HFP machine and then fix. After embedded in resin, large ultrathin sections were put on a hole grid. Then we took TEM pictures by auto-digital TEM recoding system. I succeed in records more than 30 thousand images. We developed auto-photomerge program for TEM pictures and several thousands of pictures were automatically merged. Using these wide-high resolution pictures, I have developed a web-based 2D map that can be zoomed and searched.
