Submitted by Anonymous (not verified) on Wed, 1999-03-17 08:00

Caltech biologists have harnessed a gene communication network that controls the size and shape of a flowering land plant. The discovery is a fundamental advancement in understanding the processes that make plants what they are. The knowledge could also lead to greater control over certain characteristics of plants such as fruit size and stem durability.
