a
Based on recent annotation from TIGR (http://www.tigr.org). Gene boundaries correspond to start and stop codons. Gene classes are defined by method of gene isolation.
b
Genes are placed in size groups: 1+ kb includes all predicted genes between 1.00 and 1.99 kb in length; 2+ kb includes those between 2.00 and 2.99 kb; etc.
c
Includes mutant genes identified by transposon tagging and other combinations of methods.
