This study investigated the impact of nighttime temperature and elevation on oil erucic acid content rapeseed (Brassica napus L.) seeds, focusing role sugar synthesis in silique wall as a substrate for synthesis. Field experiments across different altitudes controlled low (LNT) treatments (20/18 °C 20/13 °C) were conducted. Transcriptome analysis walls was performed to explore gene expression changes. The results showed that higher lower temperatures significantly increased seed content, particularly strong temperature-sensitive line (STSL) seeds. LNT conditions promoted sucrose transport by upregulating genes involved (SUT, SWEET, SUC1) transcription factors (WRKY51, NAC104). This, turn, enhanced availability Furthermore, associated with biosynthesis (SAD, FAD2, KAS) upregulated under LNT, promoting accumulation. In conclusion, is critical factor influencing Low enhance wall, leading These findings provide insights breeding strategies aimed at improving varying climatic conditions.
