Does anyone have any thoughts about the genetic control of
diverse morphological structures in different types of plants. The reason i ask
is that I use to work on a wonderul set of mutants in peas,
one of which (the afila mutation) converts leaves into tendrils and
began wondering whether it is likely that such a gene would exist
in Arabidopsis, which, to m knowledge, cant prodce tendrils. Is it
likely that plants which produce distinct types of structures contin a spoecific sub-set of genes
which are missing in other plants? or do most plants contain more or less
the same genes, some of which are not expressed or have evolved to
perform different functions?
Any thoughts on this would be most interesting!
