And Buschmann, 2001): two.six. Chlorophyll content material [g/ml] = 12.66 g/ml AnmThe quantity of carotenoids within the sample was quantified by the absorbance maximum on the sum of carotenoids at 470 nm (A470nm) along with a correction term thinking about absorbance of chlorophyll a at 470 nm (c (Chl a): concentration of chlorophyll a within the sample) working with the following equation: Carotenoid content material [mg/ml] = (1000 g/ml A470 nm 1.91 c (Chl))/225. two.7. RNA extraction qRT-PCR RNA extraction was performed in line with (Pinto et al., 2009). Briefly, 0.2 ml cell culture was collected and pelleted for three min at maximum speed at 4 C. After discarding the supernatant, the pellet was resuspended with 0.five ml PGTX and incubated at 95 C for five min. After cooling on ice, 350 l chloroform/isoamyl alcohol have been added along with the mixture was incubated shaking gently at room temperature for ten min. To separate the aqueous from organic phases the mixture was centrifuged for ten min at maximal speed at four C. The upper phase was transferred to a fresh tube and 1 vol chloroform/isoamyl alcohol added. Right after repeating the centrifugation step the upper phase was once more transferred and precipitated with three vol of 100 Nav1.3 Accession ethanol sodium acetate at 20 C overnight. The RNA was pelleted for 30 min at maximum speed and 4 C, washed twice with 70 ethanol and resuspended in RNase-free water. RNA was DNaseI-digested applying commercial DNaseI from ThermoFisher (EN0525), as outlined by the manufacturer’s specifications. DNaseI-digested RNA was phenol/chloroform extracted again to get rid of the DNaseI. For cDNA synthesis, the commercial RevertAid RT from ThermoFisher (K1621) was utilised as outlined by the manufacturer’s specifications. qRT-PCR was performed working with the DyNAmo ColorFlash SYBRTM Green qPCR-Kit (ThermoFisher, F416L), according to the manufacturer’s specifications. two.8. GC-MS for the quantification of volatile sesquiterpenoids one hundred L dodecane overlay fractions were collected in micro inserts inside 1.5 mL clear glass GC vials. 2 L in the sample have been diluted 1:50 in HPLC grade hexane (Th. Geyer GmbH, Germany) before injection. 1 l of the diluted was injected with an MPS autosampler with automatic liner exchange system in conjunction having a cold injection technique (Gerstel) in splitless mode (ramping from 50 C to 250 C at 12 C s 1) in to the GC with a helium flow of 1 ml min 1. Chromatography was performed utilizing a 7890B GC technique (Agilent Technologies) with a HP5MS column with (5 -phenyl)-methylpolysiloxane film (Agilent, 19091S-433, 30 m length, 0.25 mm internal diameter, 0.25 M film). The oven temperature was held continuous at 70 C for 2 min then ramped at 12.five C min 1 to 320 C at which it was held Nav1.4 supplier continual for five min; resulting within a total run time of 27 min. Metabolites have been ionized with an electron effect supply at 70 eV and 200 C source temperature and recorded within a mass array of m/z 60 to m/z 800 at 20 scans per second with a 7200 GC-QTOF (Agilent Technologies) just after a solvent delay time of eight min. Compound identification was carried out by way of MassHunter Qualitative (v b08.00, Agilent Technologies) by comparison of mass spectra for the NIST14 Mass Spectral Library (https://www.nist. gov/srd/nist-standard-reference-database-1a-v14) and validated by retention time comparison with chemical reference substances (SigmaAldrich, #06808). Peaks had been integrated making use of MassHunter Quantitative (v b08.00, Agilent Technologies). The concentration was determined via external calibration. The calibration curve wa.
