Assembled ''bar'' in pSB1C3 and submitted for sequencing. The Gibson of ''hph'' into pSB1C3 was rerun. An experimental method of ligating ''crtY'' into pAK13D upstream of the T7 promoter was tried as an alternative to gel purification and PCR purification, since we lack the primers to PCR and gel purification interferes with ligation. |
|tech=Digested ''nptII'' in pCg13S with EcoRI+XbaI, and TtrpC with EcoRI+SpeI. The ''crtY'' in pSB1C3 was digested four different ways: One with just XbaI & PstI; one with XbaI, PstI, and SacI; one with XbaI, PstI, and ApaLI; and one with XbaI, PstI, SacI, and ApaLI. Although unlikely, this method is intended to prevent re-ligation of the backbone of ''crtY'' during digestion. More ''crtY'', ''crtI'', ''crtB'' was inoculated in liquid cultures for future miniprepping. | |tech=Digested ''nptII'' in pCg13S with EcoRI+XbaI, and TtrpC with EcoRI+SpeI.

- | |tech= A glycerol stock of pCh13V (''hph'' Gibson) was created, then miniprepped for later site directed mutagenesis of ''hph'' (which has both E and P cut sites). Digestions of pC13M (crtB) and pC13E (T7 polymerase) were column purified and quantified. The PCR of pC13K with GC and non-GC trials was redone, since the fragment was of the incorrect length during gel imaging yesterday - goal is to ligate to pAK13D. Following the PCR, a gel was run which showed no bands. Perhaps the polymerase was forgotten? Another PCR of pC13K was performed and run on gel. A band showed at exactly 1.8kb as expected. pC13M was ligated to pAK13D, placing crtB downstream of the T7 promoter. pC13E was ligated to pC13P, placing the ''T7'' polymerase gene downstream of PtrpC (a native fungal promoter) - this is the first part of our genetic circuit with the second being the ''T7'' promoter upstream of various genes (GFP and RFP for diagnostic purposes - to quantify promoter functionality and the carotenoid genes for proof of concept). Plates of pC13AH (T7 + crtY) had many colonies, so they were restreaked, and colony PCRs were run while cultures were made of some of the colonies. A gel of the PCRs was run (image name was pC13AHcolonypcr7-17-13); gel was inconclusive (correct band was accompanied by strong incorrect band at 1kb).

|tech=All 18 (yes, 18!) of the ''pC13AH'' colonies that had been screened by colony PCR yesterday were miniprepped. We digested the miniprepped colonies of pC13AH clones (T7 promoter with crtY in pSB1C3) with ''NotI'' to see if the restriction cocktail method of cloning worked.

Digested pC13Z, pC13M, pCp13X, pC13K (''crtI'') with XbaI and PstI in addition to ApaLI and SacI for later ligation with pAK13. pAK13D had been previously digested with SpeI and PstI, column purified, and dephosphorylated for insert ligation. More pAK13D was grown to acquire more DNA to be miniprepped tomorrow. Nupur performed colony PCR and made cultures of transformants from yesterday.

Transformations of ''AI-AL'' (mRFP cds and lox site parts) all yielded colonies, though at really low efficiencies compared to most transformations off of kit plates.

DNA was present but in low concentrations that we could not check on a gel. We had transformants for pC13BX and pC13CJ so we ran a colony PCR and made cultures. The colony PCRs showed little to nothing on the gel, perhaps because Taq polymerase lost activity. We will miniprep the culture and use Q5. We also attempted a restriction cocktail digest today for both ''mRFP'' and ''GFP'' inserts. We cut pC13Z and pC13AK with Xba, PstI, SacI, and ApaLI. We also performed a colony PCR of pC13AT cultures and pC13AU cultures using primer 23 and 24 to verify length of inserts. The lengths should be around .7kb for each insert. When we ran a gel of the PCR products, the colony PCR showed a .7kb insert for pC13AT colony 1 and a .3kb insert for pC13AT colony 2. The bands for pC13AU were inconclusive. We will miniprep the potential pC13AT colony 1 and send for sequencing once the miniprep kit arrives. We digested our plasmid pAh13G with SphI in order to create linear DNA for fungal transformation. We attempted to transform this into what <i>G. lucidum</i> protoplasts we had generated, but the electroporation lead to arcing. Arching most likely resulted from the sodium citrate in the cell solution which we were instructed to use by the literature.

Arching most likely resulted from the sodium citrate in the cell solution which we were instructed to use by the literature. Nevertheless, we plated the cells on hygromycin cym agar. | ||

BL21-A1 seems to have a higher transformation efficiency.We started cultures and performed a colony PCR from the DH5α plate. We ran a gel of the colony PCR and pC13CG 1, 3, and 4 had the correct band at about 1.8 kb. pC13A and pC13F (XbaI,PstI) did not have enough DNA. As a result, ligations for creating pC13I and pC13J are on hold. We ligated and electroporated pC13AF, pC13AG, pAK13CR, pAK13CS from other digestions, and plated them overnight. We found the the transformations of pC13BR and pC13BQ were too efficient and had to restreak the plates in order to isolate single colonies.

We transformed the ligations of pC13BC, pC13BV, and pC13CE into <i>E. coli</i>, but both attempts for pC13CE arced, so we started another ligation for pC13CE. |

+ | |tech= Today, parts for pC13BN were DpnI digested, purified and Gibson assembled. We also performed a PCR of pC13F to append BamHI and KpnI restriction sites to the pSB1C3 backbone. The goal was to digest pC13F with BamHI and KpnI and ligate <i>PpelA</i> in place of ‘’mRFP’’ using BamHI/KpnI digested pA13BE (part pHNU3pelA). pA13BE is a plasmid generously given to us by the Turgeon lab at Cornell and contains the ‘’PpelA’’ flanked by BamHI and KpnI restriction sites. Thus, transferring ‘’PpelA’’ to the pSB1C3 backbone (creating the part pC13BF) would allow constructs made with ‘’PpelA’’ to be BioBrick submissible. All 4 of the PCRs (in addition to the BamHI/KpnI digestion of pA13BE) seemed successful upon gel electrophoresis. We also received the <i>A. nigers</i> <i>pkiA</i> promoter (‘’PpkiA’’) and <i>xlnD</i> terminator (‘’TxlnD’’) from the Wageningen team, which we plan on characterizing by cloning ‘’GFP’’ and ‘’mRFP’’ (in separate constructs) between the two. | ||

We ran Gibson assemblies of the left and right homology regions of <i>G. lucidum</i> with pC13Y, pC13BQ and pC13BR and transformed them. The sequencing of <i>Psal</i> was weird: the primer appeared to fall off after amplifying the cut sites. We will resubmit for sequencing after looking at a digest screen. We miniprepped pC13Z, pC13F, ‘’PpkiA’’, and ‘’TxlnD’’. ‘’PpkiA’’ and ‘’TxlnD’’ were submitted for sequencing to verify Wageningen had sent the correct parts. For some reason, the pC13BF cultures did not grow so we decided to give them another day to grow before miniprepping and sequencing (to confirm the success of the ligation). Finally, on carotenoids we miniprepped pAK13CS, pAK13AA, pC13DT, as well as ‘’PT7’’ and ‘’rbs’’ with ‘’crtEB’’, and ‘’PT7’’ with ‘’crtBI’’. After quantification, a PCR with extended an annealing time was run to confirm the sequence. | ||

We set up PCRs of inserts from pC13AT, pC13AU, pC13AV, pC13AY, pC13CC, and pC13CE constructs to append HindIII and KpnI cut sites using new primers. The plan is to transfer the inserts into pAg13H and pAh13EA vectors. Next, we digested pAg13H and the successful PCRs of pC13AT, pC13AU, and ‘’pC13AV’’ with HindIII and KpnI and ligated overnight. The successful transformants from yesterday’s Gibson assemblies were cultured, and we ran a digest screen of all Psal minipreps with low yields: the image showed correct bands. Ran a PCR overnight of the <i>Psal</i> F and <i>Psal</i> R primers that just came in to amplify out Psal with its activator (nahR with P constitutive promoter). The SpeI cut site on will be appended by the reverse primer, while the forward primer is just amplifying the region already containing the BioBrick prefix. We also grew 10 ml overnight cultures of pC13P & pC13BA in LB and Chloramphenicol. Overall a productive day. | ||

The pC13BF cultures still have not grown, causing us to surmise that the bacteria in the culture are contaminants that somehow acquired antibiotic resistance. Due to our time constraints and the amount of troubleshooting that would be required to successfully construct pC13BF at this point, we decided to abandon submitting pC13BF as a BioBrick. As a result, we prioritized our remaining time to characterize the parts sent to us by Wageningen. Thus, we digested our ‘’PpkiA’’ minipreps with SpeI and PstII and also digested ‘’TxlnD’’, pC13Z, and pC13F with XbaI and PstII, the goal of which was to successively ligate ‘’GFP’’ and ‘’mRFP’’ (in separate constructs) downstream of the ‘’PpkiA’’ promoter followed by ‘’TxlnD’’ downstream of the fluorescence genes. | ||

The drylab team met briefly on June 17 to begin discussing some ideas. We went over some of the growing methods for Ganoderma lucidum, brainstormed some non-packaging related ideas for a fungal biomaterial, and discussed how we could test some of the physical characteristics of the final product. We thought it might be a good idea to test the thermal conductivity if it were to be used as a drinking cup. We also determined that people probably do not want to drink out of a fungus cup.

The drylab team met to update each other on some of the preliminary research. The main focus of this meeting was the development of a growing protocol. Sara found a professor that we could contact in the material science department for help regarding the testing of material properties.

We started cloning crt genes downsteam of the T7 promoter. Because the T7 promoter is too small to extract as a fragment, we're placing crt genes downstream, then transferring the promoter+gene fragments back to pSB1C3. Today we digested crtY and the T7 promoter plasmid, but the digestion of crtY failed.

Unfortunately, there were no colonies on the transformation plate for T7 + crtY, so we redid the digestions for those. We also digested TtrpC and nptII for the eventual cloning of a PtrpC+nptII+TtrpC construct (we have to put the parts together in reverse because nptII contains a PstI site, which we will be trying to remove as well). Gel extractions of digested crtI and crtB were also empty (insignificant concentrations), so these digestions were also redone, and all were run on a gel, which looked mostly okay.

There were no transformants, again :(. On the other hand, we received our tube of Ganoderma Lucidum from Dr. David Hibbett today! Once more with feeling, we redid the four digestion-ligations for crtI, crtB, crtY, and nptII. We also amplified hph, the hygromycin resistance gene, from one of the plasmids we got from Dr. Turgeon's lab, as well as pSB1C3 backbone, and we will use Gibson assembly to put them together (as hph has both EcoRI and PstI sites)-- the gels looked good for both of these. Finally, we submitted pAb13T (pBARGPE1) for sequencing to determine the sequences of the Aspergillus nidulans gpdA promoter and the bar gene, which confers phosphonothricin resistance.

All transformations failed yet again, and were repeated once more. Four tears shed for the lost. hph was Gibson-assembled, and we ran a Q5 PCR of the bar gene, under the assumption it matches other published bar sequences, and the product digested and ligated with pSB1C3. We also ran site-directed mutagenesis on nptII (pCg13R) to remove its internal PstI site.

Ritvik, Manny, and Mac began coming up with design considerations for the incubation chamber. We were most concerned with size; too small and it wouldn't be useful, too big and it would be difficult to control any variables. We eventually decided that a 1'x1'x2' chamber would probably be a good compromise. Rebecca, Sara, Ritvik, and Mac also attended machine shop training this week. In order to complete our training, we each had to construct a small aluminum lamp using a milling machine and a lathe.

Digested and ligated the Anderson promoter+T7 polymerase into pSB1C3 and pSB2K3 as well as start cultures from glycerol stocks and transformation and gel screened the Anderson promoter + T7 polymerase. We transformed afp1 and Cht1_2. For fluorescence, we electroporated pC13AU, pC13AT, pAK13CY, and pC13AQ to obtain more plasmid DNA. We redid a Q5 PCR for pC13CV, pC13I, pC13AF and pC13L with the new dNTPs--PCR products were all bad except for pC13L.

After researching we found out that the powerpoint presentation should be centered around design and images rather than content. We decided to meet tomorrow to discuss possible design layouts and schemes. We looked at many examples of presentations and considering our project, we think we should have a very modern and green theme. Arun will explore with this later on.

PpelA preps were quantified and the G. lucidum promoter was amplified and gel screened. We are preparing our pC13CO, pC13BA, and pC13CL cultures to sequence. The correct insert is in pC13BA based on a gel screen. We digested pC13L and dephosphorylated the pSB1C3 digest from yesterday. We prepared an overnight culture of Cochliobolus and necessary solutions for a protoplasting attempt tomorrow.

After picking up our pieces from the Clark Hall machine shop, we focused on cutting our insulation to the proper dimensions. Initially, we tried cutting it with a razor blade, but after some rather sloppy results, we decided we needed a more efficient cutting method. Our next attempt involved heating a thin wire and melting through the insulation. This produced better results than the razor blade, but was way too slow. Finally, we decided it would be best if we just resorted to power tools. We bought a jigsaw from Home Depot and cut the insulation like it was cheese. After, we gazed fondly upon the jigsaw and reminisced about high school woodshop.

Anderson promoter + T7 polymerase, in pSB1C3 and BBa_J61002 were miniprepped, glycerol stocked, and prepared for biobrick submission. For fluorescent constructs, a Q5 PCR of pAK13AO colonies 1,2,3 and pC13CB 1,3,4 all had correct lengths. The pC13BN construct was incorrect. An overnight culture was prepared for rbs + crtI (from pC13L) at 4C. We made our first attempt at protoplasting and transforming Cochliobolus with the help of the Turgeon Lab. We set up cultures of pC13X and pC13AV in preparation for part submission. We started the growth experiment for testing G. lucidum’s antibiotic sensitivity.

Redid transformations of PpelA and the Anderson promoter+T7 polymerase. We sent the Anderson promoter, pC13CO, pC13CL, and pC13BA to sequencing. Gel electroporation for pC13I showed that it was good, but nothing for pC13J. We were surprised to know that rbs + crtE (pC13J) already exists in iGEM! We continued with protoplasting Cochliobolus in the Turgeon Lab, and we ran a Gibson assembly of homology regions in G. lucidum.

Ran Gibson assembly for the G. lucidum promoter into pSB1C3. pC13BA is now a BioBrick! We also began cloning a construct with both fluorescence and resistance genes by ligating pC13BR and pC13AT. We successfully electroporated E.Coli with pC13J! We digested pAK13CR, and then we ligated rbs + crtB into pSB1C3, crtE into pSB1C3. After finding our Gibson assembly from last night left in the water bath, we attempted it again as well as preparing some of our Biobricks for submission. We checked pC13BC, pC13BV, and pC13CE and prepared the successful constructs for sequencing.

We started taking measurements of G. lucidum growth on CYM plates by tracing the central mass of fungus--the differences between the plates are really interesting! Sequencing for pC13AY was successful so we prepared more culture. We did gel electrophoresis for inserts in pC13CV, pC13I, pC13J and pC13BG, but only pC13J colonies are positive. We then did digestions for the following vectors: pC13BG, pC13AG, and pC13KI. We still do not have any growth on antifungal plates.

Compared with last week’s jigsaw induced excitement, this week was relatively tame. With all of the necessary pieces in our possession, we set out to assemble our incubator. After sifting through the leftover drylab supplies from last year’s project, we came up with a couple tubes of silicone adhesive that we could use. Insulation pieces were adhered to their respective plastic backings and were allowed to dry for a couple days.

This week, the incubator box was completed. The fabrication and electrical groups came together to begin combining and testing. Initial tests with the temperature sensor yielded very positive results. We were able to successfully set and reach a target temperature with our sensor/feedback system. Unfortunately, our humidity sensor malfunctioned while we were running tests, however, we were still able to gather some data. Initial humidity tests indicate that our misting apparatus is able to produce a 12% increase in humidity over a time span of 8 minutes. Using a hotter water supply, as well as allowing the misting apparatus to run for longer would certainly allow us to increase humidity even more.
