Orbach/Sachs cosmid library of N. crassa DNA sequences
(pMOcosX).
The vector pMOcosX has dominant selectable markers for fungi (hygromycin resistance)
and E. coli (ampicillin resistance). To prepare the library, pMOcosX was digested with
XbaI and the ends treated with phosphatase. The vector was then digested with XhoI
and the ends partially filled in with dCTP and dTTP using klenow. 74-OR23-1VA DNA
was partially digested with MboI and the ends partially filled in with dATP and dGTP
using klenow. The vector and genomic DNAs were ligated. The ligated DNA was
divided into two parts. One part was packaged using Stratagene gold II extracts and the
other part was packaged using Stratagene XL II extracts. The packaged material was
plated on host strain DH5aMCR. 2400 colonies were picked from each packaged DNA
set to 25 microtiter plates so that the entire library consists of 50 microtiter plates.

This library was constructed using the cosmid pcosAX as a vector and partially digested chromosomal DNA extracted from a wild type strain (ORS-a, FGSC 2490) as inserts. Cosmid pcosAX (designed, constructed, and provided by Dr. John Hamer, Purdue University) is a pWEl 5 derivative that contains the argB gene from Aspergillus nidulans substituting both the origin of replication (SV40ORI) and the Neomycin resistance gene (Neor). In addition, pcosAX also contains an extra Xhol restriction site inserted in between the T3 and T7 RNA polymerase phage promoters. To construct the library, pcosAX was digested with Xhol, the ends of the vector were then partially filled-in with dCTP and dTTP using DNA polymerase I - Klenow fragment, and dephosphorylated with alkaline phosphatase. 2490 DNA was partially digested with Sau3A and the ends were partially filled-in with dATP and dGTP using DNA polymerase I - Klenow fragment. Vector and genomic DNAs were ligated and packaged using Gigapack XL extracts (Stratagene). The packaged material was plated on host Escherichia coli XLl Blue MR (Stratagene). 24,000 colonies, corresponding to the primary library were pooled together and stored at -70 C using standard procedures. The frozen pool contains approximately 3 X 109cfu/ml.

All clones are end-sequenced and as such can be identified on the Neurospora genome.
This library will be described in the Fungal Genetics Newsletter.

N. crassa cDNA libraries constructed by Matthew Sachs
Two cDNA libraries, which represent mRNA from the Neurospora crassa wild type strain, 74-OR23-1VA, were constructed in Lambda Zap version I+ (Short, Fernandez, Sorge and Huse. 1988 Nucl. Acids Res. 16:7583-7600) as described (Orbach, Sachs and Yanofsky. 1990 J. Biol.Chem. 265:10981-10987). cDNA libraries were prepared from macroconidia incubated in 1X Vogel's minimal medium with 2% sucrose for 0.5, 1, and 2 hours (combined to obtain the germinating library) and 6 hours (mycelial library). The mycelial library is estimated to contain 3.25 x 10^5 independent clones (75% recombinant). The libraries are supplied as lambda phage in SM containing 7% DMSO. A working aliquot of the library may be stored at 4 C. The remainder should be quick frozen in liquid nitrogen and stored below -70 C.
The germinating conidia library is no longer available.

Nitrogen induced cDNA libraries constructed by R.H. Garrett
One library (NO3- induced) was made from poly(A)+ RNA isolated from Neurospora
crassa mycelia grown on Vogel's minimal made with 3% sucrose and
20 mM glutamine, then induced for nitrate assimilation by transfer to a
medium containing 20 mM nitrate as the sole N-source. The other library
(glutamine-grown) was made from poly(A)+ RNA isolated from mycelia grown as
above, then transferred to a medium containing 20 mM glutamine as the sole
N-source. cDNA in each library was prepared from poly(A)+ RNA using the
Pharmacia cDNA kit, ligated on EcoRI adapters, and cloned into lambda ZAP
version II+ Both libraries are >98% recombinant phage as judged by
blue/white selection and by individual plaque isolation.

2. Mycelial library: M-1, constructed with mRNA from conidia of 74A grown in 1X Vogel's and 2% sucrose, shaking at 25 C for 24 hours
3. Mycelial library (Westergaard's): constructed with mRNA from conidia of 74A grown in 1X Westergaard's and 1% sucrose, floating at 25 C for 1.5 days
4. Perithecial library: P-1, constructed with mRNA from 5 day-old perithecia [the fluffy a strain (FGSC #4347) was grown on crossing plates covered with sterile Miracloth circles and fertilized with a heavy conidial suspension of the opposite mating type (74A)---> day 0]
The libraries were constructed using the Uni-ZAP XR vector system
(Stratagene). Detailed description of screening and manipulation of the
libraries can be found in a Stratagene's instruction manual. The
bacterial strain XL1-blueMRF' can be used to plate the libraries. To
excise the pBluescript containing the cDNA from the library, a helper phage
(ExAssist) and an E. coli(SOLR) are needed.
