Short Description of Library:
The cDNA library was constructed from mRNA isolated from very young seeds (less than 20 mgs). 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.

Titer of cDNA clones: 5 x 105 CFU/ml
Percent white colonies: 78%
Average insert size: 810 bp

Genotype/Cultivar:
Williams 82

Organ/Tissue:
very young seeds, less than 20 mg

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.
