Gene Expression System

Functional characterization of plant agrichemical transporters provided an opportunity to discover molecules that have a high mobility in plants and have the potential to increase the amount of pesticides reaching damage sites. Agrobacterium-mediated transient expression in tobacco is simple and fast, and its protein expression efficiency is high; this system is generally used to mediate heterologous gene expression. In this article, transient expression of tobacco nicotine uptake permease (NtNUP1) and rice polyamine uptake transporter 1 (OsPUT1) in Nicotiana benthamiana was performed to investigate whether this system is useful as a platform for studying the interactions between plant transporters and pesticides. The results showed that NtNUP1 increases nicotine uptake in N. benthamiana foliar discs and protoplasts, indicating that this transient gene expression system is feasible for studying gene function. Moreover, yeast expression of OsPUT1 apparently increases methomyl uptake. Overall, this method of constructing a transient gene expression system is useful for improving the efficiency of analyzing the functions of plant heterologous transporter-encoding genes and revealed that this system can be further used to study the functions of transporters and pesticides, especially their interactions.

Here we report on a simple and reproducible system of Agrobacterium-mediated transient gene expression assay that utilizes infiltration of young Nicotiana benthamiana leaves. Although some of the phenomena described in this paper have been already reported by other researchers, here we have further developed them. The highest level of transient gfp gene expression was detected in the youngest leaves of N. benthamiana infiltrated with A. tumefaciens strains AGL0 and EHA105 precultured in the presence of 450-600 microM acetosyringone. Although the maximum level of transient gfp gene expression was restricted presumably by RNA silencing, it was completely suppressed in the presence of the viral protein HC-Pro. The transient expression system described here can be used to identify new viral suppressors of RNA silencing, for detailed analysis of unidentified genes and for industrial production of proteins in plants as well.

AbstractNicotiana benthamiana is used extensively as a platform for transient gene expression and as a model system for studying plant-virus interactions. However, many tobacco-feeding insects, e.g. Myzus persicae (green peach aphids) and Bemisia tabaci (whiteflies), grow poorly on N. benthamiana, limiting its utility for research on plant-insect interactions. Using CRISPR/Cas9, we generated knockout mutations in two N. benthamiana acylsugar acyltransferase genes, ASAT1 and ASAT2, which contribute to the biosynthesis of insect-deterrent acylsucroses. Whereas ASAT1 mutations reduced the abundance of two predominant acylsucroses, ASAT2 mutations caused almost complete depletion of foliar acylsucroses. Both M. persicae and B. tabaci survived and reproduced significantly better on asat2 mutant plants than on wildtype N. benthamiana. Furthermore, ASAT1 and ASAT2 mutations reduced the water content and increased the temperature of leaves, indicating that foliar acylsucroses can protect against desiccation. Improved aphid and whitefly performance on ASAT2 mutants will make it possible to use the efficient transient overexpression and gene expression silencing systems that are available for N. benthamiana to study plant-insect interactions. Additionally, the absence of acylsugars in ASAT2 mutant lines will simplify transient expression assays for the functional analysis of acylsugar biosynthesis genes from other Solanaceae.
