Objects of research--genes of A. fumigatus, C. glabrata, C. neoformans, D. hansenii, E. cuniculi, E. gossypii, K. lactis, M. grisea, N. crassa, S. cerevisiae, S. pombe, U. maydis and Y. lipolytica fungi genomes. Methods of research are computer calculation. The content of genes with exon-intron structure in fungi genomes are from 0.7 to 97.0%. The exon-intron gene structure was changed when the portion of genes with introns increased. In A. fumigatus, C. neoformans, M. grisea, N. crassa, S. pombe and U. maydis genomes that linear dependence between gene lengths, sum of exon lengths and intron number in genes was established.
