In 1993, the two scientists' laboratories began working together to put the three essential genes from a daffodil into rice.

Therefore, if a collection of all the essential genes were put together, a minimum genome could be created artificially.

A number of projects have attempted to identify the essential genes of a species.

The number of essential genes is different for each organism.

In fact, each organism has a different number of essential genes, depending on which strain (or individual) is tested.

The organisms listed in this table have been systematically tested for essential genes.

PfRh5 is located within the rhoptries and appears to be an essential gene.

It appears to be an essential gene in the blood stages.

It is an essential gene for completion of the asexual cycle.

It appears to be an essential gene but its specific function is currently unclear.
