Species having at least 200 genes covered by multiple data sets are listed here; the species are ordered first by the kingdom they are in (the 1st column) and then by the number of genes covered by multiple data sets (the 5th column). Essential genes are those that are essential in any collected data sets, i.e. genes that are essential in one data set but non-essential in others are also counted. The proportion of conditionally essential genes (PCEG, percentage in parentheses of the last column) is calculated as the ratio between the ‘conditionally essential genes’ (the last column) and the ‘genes covered by multiple data sets’ (the 5th column). Please note that text-mining results, if available, will be counted as one data set in a species; please consult the ‘Browse’ page of the database for a complete and interactive version of the table.
