TG accumulates under HS and becomes more saturated. A, The depicted lipid subclasses from pollen tubes grown under different temperature regimes were investigated. Lipid subclass profiles were measured by UPLC-nanoESI-MS/MS. Values are given as mol % of all detected lipid species per subclass. Only major lipid species (>1% of total) are depicted. For statistical analysis, ANOVA was performed (significance level α = 0.05), followed by post hoc Tukey’s analysis. n = 5. Error bars represent standard deviation. Results are presented as compact letter display of all pair-wise comparisons. B, Absolute quantification of TG from heat stressed and non-stressed pollen tubes per 1 mg of dry pollen. Also shown is the relative contribution of the respective fatty acids to the total TG amount. Measurements were performed with GC-FID and quantified as peak areas. n = 5. Error bars represent standard deviation. ***P < 0.005; **P < 0.001; *P < 0.05; determined by Student’s t test.
