Short Description of Library:
The cDNA library was constructed from mRNA isolated from senescing leaf tissue of mature greenhouse grown plants of the cultivar Williams 82. Complementary DNA was synthesized from mRNA using a 3' anchored poly (dT) primer. EcoR I adapters were ligated to the blunt-ended cDNA fragments followed by digestion with EcoR I and HindIII. The cDNA fragments were directionally cloned into the EcoR I-Hind III restriction site of the pT7T3-Pac vector. The ligated cDNA fragments were transformed into DH10B host cells (Gibco BRL).

Genotype/Cultivar:
Williams 82

Organ/Tissue:
Senescing leaves, mature plants, greenhouse grown.

Vector Information:
The cDNA library was prepared using the pT7T3-Pac vector (pT7T3, Pharmacia) 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 105 cfu/ug cDNA
Ligation Efficiency (white cfu/total cfu X 100) = 97%
Library Titer = ~7 cfu/uL
