Abstract:

Very-long-chain (VLC) alkanes are the main components of cuticular wax in Brassica napus, which play a key role in preventing non-stomatal water loss. BnCER1-2 is the core enzyme that catalyzes the synthesis of VLC alkanes in B. napus. However, it is unclear whether BnCER1-2 protein regulates VLC alkane synthesis by interacting with other proteins. Four genes potentially involved in VLC alkane synthesis, BnCER3.a10, BnCER3.c02, BnCYTB5B.c09, and BnCER1-L2.a05, were screened previously by the transcriptome in B. napus with differential wax load. In this study, their coding sequences were cloned from B. napus. A typical fatty acid hydroxylase domain and a wax2 C-terminal domain were detected in the predicted BnCER3.a10/c02 and BnCER1-L2.a05 proteins, while cyt_b5 protein family conserved domain was in the predicted BnCYTB5B.c09. Subcellular localization showed that BnCER3.a10/c02, BnCYTB5B.c09, and BnCER1-L2.a05 were all located in the endoplasmic reticulum, which were co-located with BnCER1-2. Bimolecular fluorescence complementary (BiFC) and luciferase complementation assay (LCA) revealed that BnCER3.a10, BnCYTB5B.c09, and BnCER1-L2.a05 interacted with BnCER1-2 protein, while BnCER3.c02 did not interact with BnCER1-2. The RT-qPCR indicated that BnCER3.a10 and BnCYTB5B.c09 were mainly expressed in the stems or leaves of B. napus, and the relative expression was significantly up-regulated under drought stress, which were consistent with the expression pattern of BnCER1-2. The relative expression levels of BnCER3.a10 decreased significantly under NaCl and low temperature stresses. Further, the relative expression level of BnCER3.a10 was significantly down-regulated by MeJA and ACC, while the relative expression level of BnCYTB5B.c09 was up-regulated by ABA. The highest relative expression of BnCER1-L2.a05 was in flowers and the lowest in stems and leaves, and its expression was significantly down-regulated under drought, cold, and NaCl stresses. Further, the relative expression level of BnCER1-L2.a05 was up-regulated by SA, while down-regulated by MeJA. The relative expression levels of BnCER3.a10 and BnCYTB5B.c09 in B. napus with high wax/alkane load were significantly higher than that with low wax/alkane load, while BnCER1-L2.a05 had the opposite change. Comprehensive analysis suggested that BnCER3.a10 and BnCYTB5B.c09 may promote the biosynthesis of VLC alkanes in B. napus by interacting with BnCER1-2, while BnCER1-L2.a05 may negatively regulate the synthesis of VLC alkanes by interacting with BnCER1-2.

Key words: Brassica napus, cuticular wax, protein interaction, very-long-chain alkanes
