However, nondirectional ESTs may also be used. The partial sequences are then compared to sequences in various publicly available databases for identification.
The cDNA libraries isolated from the selected transformants are amplified, isolated, and partially sequenced. The ligation mixture is transformed into competent E. The total cDNA is digested with a restriction endonuclease, size-selected by agarose gel electrophoresis, isolated, and ligated into a vector, e. In the methods of the present invention, the filamentous fungal ESTs described herein preferably represent a plurality of genes present in the two or more filamentous fungal cells to be evaluated. Other possibilities for monitoring global expression include spore morphogenesis, recombination, metabolic or catabolic pathway engineering. The methods comprise a adding a mixture of fluorescence-labeled nucleic acids isolated from the two or more filamentous fungal cells with different fluorescent reporters for each cell's nucleic acids to a substrate containing an array of filamentous fungal ESTs under conditions where the nucleic acids hybridize to complementary sequences of the ESTs in the array and b examining the array by fluorescence under fluorescence excitation conditions wherein the relative expression of the genes in the two or more cells is determined by the observed fluorescence emission color of each spot in the array.įor example, the global view of changes in expression of genes may be used to provide a picture of the way in which filamentous fungal cells adapt to changes in culture conditions, environmental stress, or other physiological provocation. There is a need in the art to provide methods for monitoring the global expression of genes from filamentous fungal cells to improve the production potential of these microorganisms. Third, EST microarrays can be organized based on function of the gene products to facilitate analysis of the results e. Second, since sequence information is available so that redundancy and follow-up characterization is minimized. The use of sequenced ESTs in microarrays compared to genomic clones or random cDNA clones provides several advantages especially for organisms whose genomes have not been sequenced.įirst, one spot on an array equals one gene or open reading frame, so redundancy is eliminated.
These disadvantages include 1 more than one gene may be represented on a single clone 2 no gene s may be encoded on a single clone 3 extensive characterization and DNA sequencing is required to follow-up array spots that appear interesting and 4 duplicity, multiplicity, and reduncancy add to the follow-up work. Microarray analyses typically follow the steps of gene selection, microarray synthesis, sample preparation, array hybridization, detection, and data analysis Watson et al. The present invention also relates to expressed sequenced tags and to substrates and computer readable media containing such expressed sequenced tags for monitoring expression of a plurality of genes in filamentous fungal cells. The present invention also relates to filamentous fungal expressed sequenced tags and to computer readable media and substrates containing such expressed sequenced tags for monitoring expression of a plurality of genes in filamentous fungal cells.
The present invention relates to methods for monitoring differential expression of a plurality of genes in a first filamentous fungal cell relative to expression of the same genes in one or more second filamentous fungal cells using microarrays containing filamentous fungal expressed sequenced tags.
