- Miraculin and brazzein constructs due to arrive on Wednesday from Mr. Gene
BioBrick Transformation
BioBrick parts from the 2010 iGEM kit were transformed and grown in highly competent TURBO bacteria.
- Wintergreen Scent Pathway:
BBa_J45700 - entire pathway, Ampicillin
BBa_J45004 - BSMT1 only, Ampicillin
(Not in 2010 BB Kit: BBa_J45017 - PchB, PchA)
- Banana Scent Pathway:
BBa_J45250 - ATF3 + Promoter, Ampicillin?
BBa_J45014 - ATF3 only, Ampicillin
(Not in BB 2010 Kit: BBa_J45400 - BAT2 and THI3)

Primer Designs for Agrobacterium Vector
- Primers were designed to amplify from the Expression Series pORE Agrobacterium plasmid (e3) 1)the pENTcup2 promoter, 2) the tNOS stop sequence, 3) the tNOS stop sequence + additional stop codon and 4) the pHLP promoter.
Note: the NOSterm_BB_R primer works for both tNOS and tNOS+STOP codon sequences.

BioBrick Transformation
- Colonies were observed after overnight culture growth, but in low quantities.
- J45700 and J45004 (both Wintergreen Pathway) showed minimal number of colonies on both 10μL and 100μL cultures.
- J45250 and J45014 (both Banana Pathway) showed no colonies on either the 10μL or 100μL cultures.
Codon Usage in Arabidopsis

Valencene Extraction
Used RNeasy Plant Mini Kit to extract RNA from the flavedo of an Organic Valencia Orange.

MiniPrep
- MiniPrep of Wintergreen parts from Registry (J45004 and J45700) following Qiagen MiniPrep protocol. MiniPrep three samples of each part.
- DNA concentrations:
J45004-1: 59.1 ng/μL
J45004-2: 72.9 ng/μL
J45004-3: 88.1 ng/μL
J45700-1: 146.7 ng/μL
J45700-2: 187.4 ng/μL
J45700-3: 175.5 ng/μL
Digestion with Enzymes
- For J45004, we added: 9μL DNA, 1μL buffer, 1μL xbaI restriction enzyme (slow), and .5μL pstI restriction enzyme (fast).
- For J45700, we added 5μL DNA, 4μL H2O, 1μL buffer, 1μL xbaI restriction enzyme (slow), and .5μL pstI restriction enzyme (fast).
- We let mixtures sit for 30 minutes due to the use of xbaI restriction enzyme (slow). After the 30 minutes, we added 2.5μL dye to each mix.
Gel
- We loaded 12.5μL of 1kb ladder to well 1 of the gel (numbered left to right). We then loaded 12.5μL of J45004-1, J45004-2, and J45004-3 to wells 2,3, and 4, respectively. We loaded J45700-1, J45700-2, J4500-3 in wells 5, 6, and 7, respectively (see images below for well locations).
- Ran on 1% agarose gel.
