Dear Arabinetters,

I am interested in the study of cambium, the LATERAL meristem that develops
in mature parts of dicots (and gymnosperms), and gives rise to SECONDARY
phloem and SECONDARY xylem, thus resulting in increase of diameter.

I suppose that in Arabidopsis the mature parts of the stem show the
development of secondary cambium:

What is the available information on the transition from procambium to
cambium and on the functioning of cambium in Arabidopsis (histological
description, time course of the different stages, previous biochemical and
molecular studies)?
Is Arabidopsis already used as a model system for the study of cambium
meristematic activity and of the differentiation of secondary xylem and

Thank you.

Ivan Couee
