Arabidopsis genes vs animal genes
When the gene content of Arabidopsiswas compared with those of the multicellular animal genomes sequenced then, it was found that in Arabidosis, the number of singletons was about 11,500 and the number of distinct gene families was about 15,000, which was little higher than that predicted for nematode worm, C elegans(13,601) and little less than that predicted for the fruitfly, D. melanogaster(18,424). However, many of the genes (presumably house keeping genes) were similar between plant and animals, suggesting common origin of animals and plants.

There were also genes in Arabidopsis genome, which were unique to plants, like those involved in the synthesis and modification of water transporting channels and the cell walls. There are other genes in plants that encode for signal peptides directing transport of specific nuclear encoded proteins to chloroplasts, so that 25% of the genes in green plants like Arabidopsisencode signal peptides used in intracellular transport as against 5% in case of animals and fungi, where signal peptides are mainly required for intracellular transport to mitochondria, the chloroplasts being absent there.
