Short Description of Library:
The cDNA library was constructed from mRNA isolated from 2-3 week old seedlings that were induced for symptoms of SDS (Sudden Death Syndrome) disease by the translocution of culture filtrate of Fusarium solani f. sp. glycines (Plant Cell Report 18:375-380). Cultivar Williams 82 is susceptible to the disease SDS. Plant tissue (expanded leaves, folded leaves, and new shoots) were collected at 1, 6, and 24 hrs after inoculation and their mRNA pooled equally for cDNA construction. The library was prepared using the Stratagene pBluescript II SK (+) library construction kit. Complementary DNA was synthesized from mRNA using a primer consisting of a poly (dT) sequence with an Xho I restriction site. Eco RI adaptors were ligated to the blunt-ended cDNA fragments followed by Xho I digestion. The cDNA insert is protected from Xho I digestion via methylation during first strand cDNA synthesis. The cDNA fragments were directionally cloned into the Eco RI-Xho I restriction site of the pBluescript vector. The ligated cDNA fragments were transformed into E. coli ElectroMax DH10B host cells.

2-3 week old seedlings, induced with SDS disease

Vector Information:
The cDNA library was prepared using the pBluescript II SK (+) vector (Stratagene) to generate a plasmid library. The vector provides ampicillin resistance and allows blue-white color selection for recombinant phagemids. The cloned cDNA fragment can be amplified by the polymerase chain reaction using one of the following vector primer pair combinations: T3 and T7 or M13 universal and M13 reverse.
