Short Description of Library:
The Harosoy NIL was constructed and seed was provided by Dr. J. Specht, University of Nebraska (Shoemaker and Specht, 1995). The cDNA library was constructed from mRNA isolated from whole seedlings of 1 week old greenhouse grown plants. Complementary DNA was synthesized from mRNA using a primer consisting of a poly (dT) sequence with a Xho I restriction site and a 3' anchor. 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). The library was constructed in cooperation with Dr. Paul Keim's laboratory (Dr. Virginia H. Coryell) at Northern Arizona University.

Genotype/Cultivar:
Harosoy (Lf1Lf1lnlny9y9Pd1Pd1dt1dt1L1L1)

Organ/Tissue:
Whole seedling, 1 week old, greenhouse grown

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 = 1 x 106 cfu/ug cDNA
Ligation Efficiency (white cfu/total cfu X 100) = 80%
Library Titer = ~200 cfu/uL
