«Probing the molecular architecture of Arabidopsis thaliana
secondary cell walls using two - and three - dimensional (13) C solid state nuclear magnetic resonance spectroscopy»
Even if researchers discover how to regulate complex sugars in
secondary cell walls in biofuel feedstocks, the next challenge will be finding how much lignin the plants can do without and still remain healthy.
Learning how to control the composition of
secondary cell walls is an area of intense interest among advanced biofuel researchers because the structures make up the bulk of the plant matter that is broken down into biofuels.
The researchers focused on
the secondary cell walls in a type of plant tissue called xylem from the Arabidopsis plant's roots.
«In order to be structurally sound, plants have to lay down
their secondary cell walls very quickly once the plant has stopped growing, like a layer of concrete with rebar,» says UBC botanist Lacey Samuels, one of the senior authors on the paper.
«The bulk of the world's cellulose is produced within the thickened
secondary cell walls of tissues hidden inside the plant body,» says University of British Columbia Botany PhD candidate Yoichiro Watanabe, lead author of the paper published this week in Science.
The study showed that «the control of
the secondary cell wall is incredibly complex and detailed, which is important for plant biologists who want to change it to make biofuels,» she said.
Solving a puzzle of plant manipulation Rather than try to isolate single genes related to
secondary cell wall production, the researchers looked at the function of hundreds of transcription factors working within the root xylem's regulatory network.

«In the end the rigid sickle
cells are really playing a
secondary role because the causality starts with the deformable
cells that stick to the
wall,» Karniadakis said.
Several functions vary among the members of this group of bacteria, such as metabolism of nitrogen, respiration,
cell wall and capsule, stress response,
secondary metabolite biosynthesis, regulation and
cell signaling; this variation in gene functions could help us understand the ability of colonization and adaptability of these rhizosphere - colonizing bacteria.
