abstract = "A novel method for regulation of gene expression for
artificial cellular systems is introduced. It is based
on an instructon-based representation which allows
self-modification of genotype programs, as to be able
to control the expression of different genes at
different stages of development, e.g., environmental
adaptation. Coding and non-coding genome analogies can
be drawn in our cellular system, where coding genes are
in the form of developmental actions while non-coding
genes are represented as modifying instructions that
can change other genes. This technique was tested
successfully on the morphogenesis of cellular
structures from a seed, self-replication of structures,
growth and replication combined, as well as reuse of an
evolved genotype for development or replication of
different structures than initially targeted by
evolution.",
