Cellular morphodynamics and genome-wide networks driving plant cell shape change

点击翻译按钮获取中文摘要

The growth of plants is driven by the division and expansion of cells. This proposal focuses on uncovering the mechanisms driving cell expansion while for the first time identifying the 3D geometrical changes in cell shape. Seed germination will be used to examine cell shape change in plants, as seeds grow only by cell expansion, while their cells do not divide. The genes and proteins that make plant cells grow will be identified using statistical analyses of existing data describing gene expression. This work will uncover the molecular processes that make a plant cell change shape.
