Our project will invite Dr. Saiko Yoshida from Laboratory of　Biochemistry, Wageningen University, Netherlands.
She will give a seminar on the Arabidopsis embryogenesis with her recent research progress.

We welcome everyone to attend this seminar!

Title: 3D Pattern formation in the Arabidopsis embryo

Speaker: Dr. Saiko Yoshida

Abstract:
  Plant morphogenesis is a genetically controlled process, and a key question is how gene activity translates to shape. We study this problem in a simple model system, the Arabidopsis embryo. Several genes have been isolated that regulate cell division and patterning during early embryogenesis¹, however little is known about the cellular mechanisms underlying the regulation of patterned growth. Additionally, while development is inherently a 3-dimensional process, it has so far only been studied in 2D. To determine the cellular basis of patterning, we established a method to visualize and segment the embryo in 3D and have generated a complete reconstruction of cell divisions in the early embryo. The result from the analysis of 3D images of embryos will be discussed.
