Description

This collection of 15 Arabidopsis thaliana Col-0 transgenic lines include: six lines over-expressing Medicago truncatula hydroperoxide lyase E (a 13 hydroperoxide lyase) either with (+) or without (-) a putative N-terminal regulatory sequence ; six lines over-expressing Medicago truncatula hydroperoxide lyase F (a 9/13 hydroperoxide lyase) either with (+) or without (-) a putative N-terminal regulatory sequence and three lines vector only controls (L700). L700 is a light specific promoter empty cassette.

Three independent T3 generated lines for each hydroperoxide lyase construct (E/F, +/-). Homozygous for a single transgene locus on the basis of segregation patterns.

Construct and transformation details

A. thaliana ecotype Columbia (Col-0) were transformed with Agrobacterium tumefasciens (GV3101) using the floral dip infiltration method.

A modified pGPTV-BAR binary vector, pL700, was used for A. thaliana transformation. MtHPL-E and MtHPL-F cDNAs were cloned into the Gateway (Invitrogen) compatible pDESTL700 plasmid; the uidA gene was excised from the pGPTV-BAR binary vector with HindIII and SstI and replaced with potato light-inducible tissue-specific ST-LS1 gene promoter (bases 73-1574 of accession X04753). In addition, a polylinker with the BlnII, SmaI, SpeI, XhoI, and BsiWI restriction sites was added between the promoter and the nos terminator. The pL700 vector was made into a Gateway (Invitrogen) destination vector (pDESTL700) by ligating the Gateway cassette A (attR1: chloramphenicol resistance gene: ccdB negative selection gene: attR2) into the SmaI site. Restriction enzyme digest analysis indicated the cassette was cloned in the correct orientation. The pL700 binary vector was used as an 'empty vector' plant transformation control.
