Short Description of Library:
The cDNA library was constructed from mRNA isolated from degenerating cotyledons of 9-10 day old etiolated seedlings for the cultivar Williams. Complementary DNA was synthesized from mRNA using a primer consisting of a poly (dT) sequence with a Xho I restriction site. EcoR I adapters were ligated to the blunt-ended cDNA fragments followed by Xho I digestion. The cDNA fragments were directionally cloned into the EcoR I-Xho I restriction site of the pBluescript vector. The ligated cDNA fragments were transformed into DH10B host cells (Gibco BRL).

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.

Transformation Efficiency = 2 x 106 cfu/ug cDNA
Ligation Efficiency (white cfu/total cfu X 100) = 80%
Library Titer = ~200 cfu/uL
