Fig. 7. The V19H four-point mutant coupled with T3R in Site directed mutagenesis of Catharanthus roseus (+)-vincadifformine 19-hydroxylase (CYP71BY3) results in two distinct enzymatic functions
Fig. 7. The V19H four-point mutant coupled with T3R converts (¡)-tabersonine to 2,3-dihydro-3-hydroxytabersonine. Traces from in vitro experiments with ()-tabersonine (1) and V19H four-point mutant microsomes or T3O microsomes in the absence or presence of purified recombinant T3R are shown. Yeast microsomes containing the V19H 4-point mutant (red) (V19HL106R–S312T-A376P–F377L) convert ()-tabersonine to tabersonine 2,3-epoxides (5) in the absence of T3R, and to 2,3-dihydro-3-hydroxytabersonine in the presence of T3R. Yeast microsomes containing wild-type T3O (blue) were used as positive controls for tabersonine-2,3-epoxide (5) and 2,3-dihydro-3-hydroxytabersonine biosynthesis in the absence and presence of T3R, respectively.

Fig. 12 in Unique chemistry associated with diversification in a tightly coupled cycad-thrips obligate pollination mutualism
Fig. 12. Boxplots of the number of thrips caught per trap in field bioassays (black horizontal bar represents the median of four replicates). Each bioassay included rubber septa infused with: dichloromethane (DCM) evaporated solvent only (Control), a mixture of standards (see Supplementary Table S1) in DCM plus prenyl crotonate (Mix + PC), and the same mixture without prenyl crotonate (Mix no PC). a) Test with low rate of prenyl crotonate, 8 μL per septum, added to the standard mixture. b) Test with a much higher rate of prenyl crotonate, 40 μL per septum, added to the standard mixture, which attracted significantly more thrips in the Mix + PC treatment. Within each experiment's boxplot, different letters across treatments indicate significant differences from one another, α <0.05, Tukey's HSD).
Fig. 1 in Unique chemistry associated with diversification in a tightly coupled cycad-thrips obligate pollination mutualism

Fig. 4. A in Unique chemistry associated with diversification in a tightly coupled cycad-thrips obligate pollination mutualism
Fig. 4. A chromatogram of a Macrozamia miquelii pollen cone sample that exemplifies the emission of high levels of certain monoterpene components (run on the DB- 5 column on Agilent QQQ GC-MS). The major confirmed components are indicated and include prenyl crotonate which was unknown until characterized in this study (see section 2.2). Nonane (IS) is the internal standard added for quantification.
Fig. 7 in Unique chemistry associated with diversification in a tightly coupled cycad-thrips obligate pollination mutualism
Fig. 7. Thermogenic temperature difference, ΔT (±1 s.e.), between pollen cones and their local ambient temperature (mean of four cones) in the field. The lower horizontal line indicates when the first thrips were observed leaving cones around noon and that they were observed flying around cones until about 16:00 h. The upper horizontal line indicates when the first thrips were captured on any treatment trap and the end time after which no more thrips were trapped that day. Ambient average was 26.3 ◦ C at 09:15, 29.1 ◦ C at 13:00 and 23.4 ◦ C at 15:00 h.

Fig. 5. A Macrozamia miquelii pollen cone sample chromatogram (Shimadzu GC-MS, ZB-5 column) representing samples in which aliphatic esters were more prominent than in Fig. 4 chromatogram. The relevant segment of the complete chromatogram is presented in (a), with confirmed components named, including prenyl crotonate and the nonane internal standard, and (b) shows an expansion of the 9.6–10.8 min retention time window as demarcated in (a) to reveal prenyl butyrate and a component marked (*), clearly related to prenyl crotonate.
Fig. 9 in Unique chemistry associated with diversification in a tightly coupled cycad-thrips obligate pollination mutualism
Fig. 9. Mean emission rates of major volatile components (±1 s.e., but not shown for those with very low emission rates) of four Macrozamia miquelii pollen cones. These were sampled in the field for 30 min over six days during pollination for both AM (morning sample start time, ~09:30 h) and midday samples (sample time started from ~11:30–13:30 h). The mean % contribution of these compounds to total emissions is reported above the bar graph of each cone and sample time. a) Emission rates of three monoterpenes, α-terpinene, α-pinene and limonene, which varied by> 5000 fold across cones (within the same sampling period). b) Emission rates of 2-methylbut-3-en-2-ol (MBO), and an aliphatic ester, prenyl crotonate, with a five-fold difference or less across cones (within the same sampling period).
Fig. 11 in Unique chemistry associated with diversification in a tightly coupled cycad-thrips obligate pollination mutualism
Fig. 11. The relative contribution (% of compound's emissions to the total volatile emissions of a sample) of six components that were statistically associated with either receptive (red, dark bar) or non-receptive (blue bar) ovulate cones, based on the results of the Indicator species analysis.

Fig. 3 in Unique chemistry associated with diversification in a tightly coupled cycad-thrips obligate pollination mutualism
Fig. 3. Composition of volatiles emitted by Macrozamia miquelii cones. Pollen cones are presented in the left hand column of pie charts, receptive ovulate cones in the middle column, and non-receptive (pre-receptive and post-receptive) cones in the right hand column. The top row of pie charts presents the mean percentage volatile emission contributed by major chemical classes and the mean emission rate (ng min 1) is presented below the chart for each cone type. The second row presents the mean percentage emissions of the different monoterpenes to the total monoterpene emissions, and the third row does the same for aliphatic esters. Each chemical or chemical class on the right hand side of the charts is identified by a matching number and color within each pie chart. (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)
Fig. 8 in Unique chemistry associated with diversification in a tightly coupled cycad-thrips obligate pollination mutualism
Fig. 8. Mean volatile emission rates (±1 s.e.) from three Macrozamia miquelii pollen cones, based on 30 min samples taken at one of three different times during one day: early thermogenesis in morning (before 10:00 h), peak thermogenesis (between 11:30–13:00 h), and late thermogenesis (>15:00 h). The mean number of compounds emitted during each period is presented above each. The midday sample start time was close to peak of thermogenesis. Bars with different letters are significantly different from one another (repeated measures test, and Bonferroni post hoc test of comparisons, α <0.05).
Fig. 10 in Unique chemistry associated with diversification in a tightly coupled cycad-thrips obligate pollination mutualism
Fig. 10. Ordination of the volatile odor (% of each compound's contribution to the total emissions) across receptive (n = 14 samples) and non-receptive (n = 11 samples, 7 pre- and 4 post-receptive) ovulate cones of Macrozamia miquelii, by nonmetric multidimensional scaling (NMSD), Bray-Curtis similarity matrix. ANOSIM, Global R = 0.65, P <0.0001, indicates a significant difference across groups, and the stress value = 0.11, K = 2, indicates a good fit of the data. There was no significant difference in the between-group multivariate dispersion test ('distance anova', P = 0.95). Each sample's position is indicated (by a dot for receptive (Rec.) or diamond for non-receptive (Non)) at the end of a spoke from the group's center. Post-receptive and pre-receptive cones are grouped together as non-receptive. The position of each post-receptive cone sample is indicated with a '+' over its diamond. The exact location of each compound that was significantly associated with each group (P <0.04, Indicator Species Analysis in R 'indicspecies') is indicated by a '*' next to the compound's name.
