| Project Title: | Comprehensive lipidomic analysis of six Hevea species and varieties related to latex biosynthesis |
| Project Summary: | In this study, we performed lipidomic profiling of latex from Hevea brasiliensis RRIM600 and five Hevea species or varieties of similar age: H. guianensis, H. pauciflora, H. spruceana, H. collina, and H. confusa. Latex samples were analysed by LC-MS/MS, identifying 53 lipid molecules from five major categories and 16 classes. Among these, triacylglycerols (TG), phosphatidic acids (PA), and acylhexosyl sitosterols are major components. Comparative analysis revealed species-specific lipid profiles: H. guianensis and H. confusa exhibited high PA levels comparable to H. brasiliensis, whereas H. pauciflora, H. spruceana, and H. collina showed elevated TG and reduced PA content. Supervised OPLS-DA analysis separated H. brasiliensis from the other species and identified 18 differentially abundant lipid molecules, including increased diacylglycerols and phosphatidic acids, and decreased hexosylceramides. These patterns may reflect underlying metabolic divergence with potential implications for latex composition and rubber biosynthesis. The dataset provides new insights into interspecific lipidome variation in Hevea and offers a valuable resource for future studies on lipid function in latex physiology and rubber properties. |
