Temporal DIA-MS proteomics reveals coordinated metabolic reprogramming associated with oil accumulation in oil palm mesocarp.

Temporal DIA-MS analysis uncovered coordinated metabolic reprogramming during oil accumulation, with 12,163 proteins changing across five developmental stages in oil palm mesocarp.

• Why it matters: Understanding the molecular mechanisms of mesocarp development and lipid accumulation is crucial for improving oil yield in oil palm, yet these processes are not well characterized at the proteomic level.
• What they did: Researchers applied ultra-deep DIA-MS to compare proteome dynamics in two genotypes, seedless (KS) and thin-shelled (TS), throughout fruit development, identifying key proteins involved in metabolism and lipid biosynthesis.
• The result: Findings revealed genotype-specific metabolic shifts, including increased lipid pathway activity and antioxidant responses in KS, providing insights into molecular networks that could enhance oil production strategies.
