Abstract

Main conclusion: Arabidopsis promoters of genesBANYULSandFRUITFULLare transcribed in Camelina. They triggered the transcription oflimonene synthaseand induced higher limonene production in seeds and fruits thanCaMV 35Spromoter.Camelina sativa (Camelina) is an oilseed crop of relevance for the production of biofuels and the plant has been target of a recent and intense program of genetic manipulation aimed to increase performance, seed yield and to modify the fatty acid composition of the oil. Here, we have explored the performance of two Arabidopsis thaliana (Arabidopsis) promoters in triggering transgene expression in Camelina. The promoters of two genes BANYULS (AtBANpro) and FRUITFULL (AtFULpro), which are expressed in seed coat and valves of Arabidopsis, respectively, have been chosen to induce the expression of limonene synthase (LS) from Citrus limon. In addition, the constitutive CaMV 35S promoter was utilized to overexpress LS in Camelina . The results of experiments revealed that AtBANpro and AtFULpro are actively transcribed in Camelina where they also retain specificity of expression in seeds and valves as previously observed in Arabidopsis. LS induced by AtBANpro and AtFULpro leads to higher limonene production in seeds and fruits than when the CaMV 35S was used to trigger the expression. In conclusion, the results of experiments indicate that AtBANpro and AtFULpro can be successfully utilized to induce the expression of the transgenes of interest in seeds and fruits of Camelina.
