Library name: Mdfr New library: Yes Plate names: Mdfr3001 – Mdfr3027; Plate format: 384-well Date plates shipped: (4/28/04) Library materials provided by: Schuyler S.  Korban Library constructed by: D.O.Gonzalez/L. Vodkin Library re-arrayed by: N/A Organism: Malus × domestica (apple) Tissue: Fruit Developmental stage: Stage I-Young Fruitlet < 1 cm Sex: (gender if applicable) Host cell: DH10B ampicillin resistant Vector: pSPORT 1 Vector_type: Phagemid (ampicillin resistant) RE_3': Not I RE_5': Sal I DESCR: Total RNA was extracted from freeze dried fruit tissue Stage I- Young Fruitlet < 1 cm, using the method described by Wang and Vodkin (Plant Molecular Biology Reporter 12:132-145, 1994). Poly(A)+mRNA was isolated from total RNA using the PolyATtract mRNA Isolation system III (Promega). The library was prepared using the Invitrogen Life Technologies, Superscript Plasmid System with gateway technology for cDNA Synthesis and cloning.  Complementary DNA was synthesized from mRNA using a Poly (dT) sequence with a NotI restriction site.  Sal I linker adapters were ligated to the blunt ended cDNA fragments followed by restriction with NotI.  The cDNA fragments were directionally cloned into the NotI-SalI restriction site of the pSPORT 1 vector.  The ligated cDNA fragments were transformed into E. coli ElectroMax Dh10B host cells. Transformation efficiency: 10E+06 colony forming units Average insert size by PCR: 992 bp
