Integrated transcriptomic and proteomic analyses uncover the early response mechanisms of Catharanthus roseus under ultraviolet-B radiation

Catharanthus roseus produces a large array of terpenoid indole alkaloids (TIAs) that are important natural source for many drugs. Ultraviolet B (UVB) radiation have been proved to have regulatory effect towards biosynthesis of TIAs, which were meaningful for boost of TIA production. To decipher more comprehensive molecular characteristics in C. roseus under UVB radiation, integrated analysis of the nuclear proteome together with the transcriptome data under UVB radiation were performed. Expression of genes related to transmembrane transporters gradually increased during the prolonged exposure to UVB radiation. Some of known TIA transporters were affected by UVB. Abundance of proteins associated with spliceosome and nucleocytoplasmic transport increased. Homologs belonging to ORCA and CrWRKY transcription factors family increased at both transcriptomic and proteomic levels. At the same time, the numbers of differential alternative splicing events between UVB-radiated and white-light-treated plants continuously increased. These results suggest that the nucleus participated in early response of C. roseus under UVB radiation, where alternative splicing events occurred and might regulate multiple pathways. Furthermore, integrative omics analysis indicates that expression of enzymes at the terminal stages of seco-iridoid pathway decreased with the prolonged radiation exposure, potentially inhibiting further rise of TIA synthesis under extended UVB exposure.
