Cellular and Developmental Biology

Cellular and developmental biology strives to develop new knowledge through basic research about the function of living organisms with focus on the cellular levels of plant life.

Research in Dr. Bar-Peled’s group aims to understand, at the molecular level, the roles of complex glycans in living organisms. We are interested in the roles of cell surface glycans (“sugar coated polymers”) in cell-cell recognition, pathogenicity, and communication between micro-organisms and their plant or animal hosts. In addition, we are…

The Dawe lab studies genome structure and cell division in maize, focusing on the biology of centromeres.  Students and postdocs work at all levels of genetics, including traditional genetics, cytogenetics, molecular genetics, epigenetics and bioinformatics. We also work intensively with microscopes to visualize cell division using fixed and…

Our laboratory studies the cell biology and biosynthesis of plant cell walls. Plant cell walls play major roles in the biology of plants. Examples of these roles include controlling the growth and shape of plant cells, tissues, organs, and ultimately the entire plant, regulating the movement of nutrients and signals within the apoplast and…

Plants, just like animals, start life as a single cell. This cell and its daughters then need to lay down the reference points required for realizing a complex body plan. We would like to understand the molecular mechanics of this process: which cues do plant embryos read-out and how do they interpret them to derive basic positional values,…

The septin cytoskeleton in Aspergillus nidulans. Septins are less familiar and less well-understood than actin and tubulins because they were discovered more recently. But, it has become very clear in the last 5 years that septins play roles as diverse and important as those of actin and tubulin.  My lab is investigating the cell biology,…

My research interests center on uncovering the molecular mechanisms underlying the biosynthesis of secondary cell walls and the transcriptional regulation of secondary cell wall biosynthesis in plants.
