Diverse sesquiterpenes in the gametophytes of R. Lindenbergiana</p><p>In this study, axenically cultured R. lindenbergiana plants were used for chemical and molecular experiments. For chemical profiling, plants were taken from axenic culture and subjected to organic extraction. The extracts were analyzed using gas chromatography-mass spectrometry (GC-MS). A total of 25 terpenoids were detected (Fig. 1), and retention indices of these compounds were calculated (Table 1). All of them are sesquiterpenes, including 7 unidentified compounds. (E,E)-α- farnesene/ β- curcumene and (Z)-β- bisabolene were among the most abundant constituents (Fig. 1).</p></div>	https://treatment.plazi.org/id/AA6F87ECFFA54B0D61393C85FC1DFD2E	Public Domain	No known copyright restrictions apply.

Terpene-producing genes from the transcriptome of R. Lindenbergiana</p><p>To identify candidate terpene-producing genes in R. lindenbergiana, its transcriptomes from the One thousand plant (OneKP) project (https: //sites.google.com/a/ualberta.ca/onekp/) were searched for TPS and MTPLS genes using a HMMER method (Finn et al., 2015). A single TPS homolog designated as RlTPS1 was identified. RlTPS1 appears to be partial sequence. The protein it encodes is most similar to MpDTPS5 from M. polymorpha (Supplemental Figure S1). Because MpDTPS5 is a putative diterpene synthase (Bowman et al., 2017), we hypothesized that RlTPS1 is also a diterpene synthase. In contrast, a total of 12 MTPSL genes were found. Five of them that appeared to be full-length genes were designated RlMTPSL1-5. A cDNA for each of the five genes was cloned by reverse transcription PCR (RT-PCR) and verified by sequencing.</p><p>RlMTPSL1-5 encode proteins of 391–441 amino acids in length (Fig. S1). Sequence similarities among the five RlMTPSLs range from 38% (RlMTPSL1 and RlMTPS4) to 71% (RlMTPSL2 and SlMTPSL3). Sequence alignment showed that they had DDXXD and NSE/DTE conserved motifs, which were reported to be involved in ionization of the substrate and catalysis (Chen et al., 2011). GenBank accession numbers for the five RlMTPSL genes are MZ367362 - MZ367366.</p></div>	https://treatment.plazi.org/id/AA6F87ECFFA54B0D61393FEAFA64FACE	Public Domain	No known copyright restrictions apply.

RNA was then converted to single-strand cDNA by GE First-strand cDNA synthesis Kit. The RlMTPSL genes were amplified by RT-PCR using the primers listed in Supplemental Table S1. The amplification products were cloned into the protein expression vector pEXP5-CT/TOPO (Invitrogen) and were confirmed by sequencing. Protein expression constructs were transferred into E. coli BL 21-Codon Plus (DE3) for protein expression and the bacteria were cultured in LB medium at 37 ◦ until OD 600 reached 0.4–0.6. The recombinant proteins were expressed for 16 h at 18 ◦ C by adding 0.4 mM isopropyl-b-D-1-thiogalactopyranoside (IPTG). The cells were collected by centrifugation at 4000 g for 10 min. After that, they were disrupted by a 8 × 10 s treatment with a sonicator (Misonix Microson ultrasonic cell disruptor, USA) in chilled extraction buffer [50 mM Tris⋅HCl, pH 7.5, 5 mM DTT, 0.5 mM phenylmethylsulfonyl fluoride (PMSF), 10% (vol/vol) glycerol]. Cell fragments were removed by centrifugation at 14,000 g for 30 min and the supernatant was desalted into assay buffer.</p></div>	https://treatment.plazi.org/id/AA6F87ECFFA24B0A626F3EFAFD7AFA6E	Public Domain	No known copyright restrictions apply.
