Today we have naming of parts

Abstract

Although we share the planet with plants and depend on them for food, raw materials and energy, we know very little about them. But this is beginning to change. On pages 761 and 769 of this issue, Lin et al. and Wambutt et al. report the DNA sequences of chromosomes 2 and 4, respectively, from Arabidopsis thaliana. The sequences include about 30% of the plant’s genes, and show that although many plant genes are familiar homologues of known animal and fungal genes, many others are plant specific. The sequences also show an evolving genome, with evidence for ancient and recent duplications of both single genes and large chromosomal regions.
