The sweet growth of plant cells
Date:6/16/2011

Porto Alegre, Brazil- Glycomics is the functional study of the entire set of sugars found in a given species. To some, the term may sound like a distant cousin of more familiar names such as genomics and proteomics. Indeed, while genomics and proteomics of several species have been extensively investigated in the last years, glycomics is still an emerging field. Now, a paper published in Science magazine by an international collaboration headed by Dr. Jose Estevez (University of Buenos Aires, Argentina) and co-authored by researchers from Argentina, Brazil, Denmark, the United States and Australia examines in depth the fundamental role that carbohydrates play in the growth of root hairs of Arabidopsis thaliana, a small flowering plant widely used as a model system in plant cell biology and development.

"The structural plasticity of carbohydrates is greater than that of amino acids but our understanding of the implications of such plasticity and how it relates to a potential biological function is still limited. This paper contributes with new insights into the fundamental role that these very dynamic compounds have in Arabidopsis thaliana" says Dr. Hugo Verli, a scientist at the Biotechnology Center of Federal University of Rio Grande do Sul (UFRGS), Brazil, and co-author of the study.

The cell wall of plants is a very rigid structure comprised largely of sugars and proteins. However, during plant growth these cells increase 200 times their original size by addition of more sugars and proteins. How does the cell wall withstand the driving forces for growth? It has been assumed that chemical changes of wall constituents and wall networks orchestrated by enzymes and cell-wall modifying genes are implicated in the process.

To investigate the issue, the collaboration group worked with the root hairs of Arabidopsis thaliana. Growing root hairs require intensive cell-wall changes to accommodate expansion at the
