The BLAST Game
This bioinformatics tool is called BLAST (Basic Local Alignment Search Tool) which is used to compare a sequence to the large public National Center for Biotechnology Information (NCBI) database where all published and much unpublished sequence data is kept (blast.ncbi.nlm.nih.gov/Blast.cgi). Type a DNA nucleotide sequence into the box to discover the organism that the sequence came from.
Abundance is the number in a square metre of soil to a depth of 23 cm.
Only a tiny minority of the archaea, bacteria, fungi and animals that inhabit soil are known; a small selection of them is represented in the Top Trumps game. There are estimated to be at least 10,000 different species of bacteria in every gram of soil but only 1% of those can be grown in the lab.
Sequencing DNA from soil indicates the number of different groups when results are compared to a sequence database and allows us to estimate abundance even when we cannot isolate the organisms. However, most of the sequences appear to come from "unknown bacteria".
Although there are many invertebrates in soil, they do not make up a significant proportion of DNA extracted directly from the soil.
The abundance data refers to the group named on the top of the card but trophic group, sequence and cell size data refer to whichever species (or nearest categorization) is named in the text.
