Short Name: SP10T0Analysis-GCMS Assay Class: WET Assay Type: GCMS Title: Analysis of SPv1.0 T0 plants Description: Stable transformation of Nicotiana benthamiana plants with the three enzymes for moth pheromone production (AtrD11, HarFAR, EaDAct) expressed constitutively pISA Assay creation date: 2021-11-01 pISA Assay creator: ElenaMG Lab manager: DO Sample collection protocol: Leaf samples were collected at 4 weeks after transplant for young stage and at 7 weeks for adult stage (early flowering). Samples were collected between 4 and 6 pm, frozen in liquid nitrogen immediately after collection, and ground afterwards. Extraction protocol: 50mg of frozen, ground leaf samples were weighed in a 10mL headspace screw-cap vial and stabilized by adding 1mL of 5M CaCl2 and 150 μL of 500mM EDTA (pH = 7.5), after which they were sonicated for 5 minutes. Volatile compounds were captured by means of headspace solid phase microextraction (HS-SPME) with a 65 μm polydimethylsiloxane/divinylbenzene (PDMS/DVB) SPME fiber (Supelco, Bellefonte, PA, USA). Volatile extraction was performed automatically by means of a CombiPAL autosampler (CTC Analytics). Vials were first incubated at 80°C for 3 minutes with 500 rpm agitation. The fiber was then exposed to the headspace of the vial for 20 min under the same conditions of temperature and agitation. Desorption was performed at 250°C for 1 minute (splitless mode) in the injection port of a 6890N gas chromatograph coupled to a 5975B mass spectrometer (Agilent Technologies). After desorption, the fiber was cleaned in a SPME fiber conditioning station (CTC Analytics) at 250°C for 5 min under a helium flow. Chromatography protocol: Chromatography was performed on a DB5ms (60 m, 0.25 mm, 1 μm) capillary column (JandW) with helium as the carrier gas at a constant flow of 1.2mLxmin-1. Oven programming conditions were 40°C for 2 min, 5°Cmin-1 ramp until reaching 280°C, and a final hold at 280°C for 5 min. Mass spectrometry protocol: Electron impact ionization (EI), 70 eV ionization energy, MS source temperature 230ºC, MS quadrupole temperature 150ºC, single quadrupole detector, m/z range 35-300.
