Agroinfiltration and PVX Agroinfection in Potato and Nicotiana benthamiana
Agroinfiltration and PVX agroinfection are two efficient transient expression assays for functional analysis of candidate genes in plants. The most commonly used agent for agroinfiltration is Agrobacterium tumefaciens, a pathogen of many dicot plant species. This implies that agroinfiltration can be applied to many plant species. Here, we present our protocols and expected results when applying...
متن کاملBacillus thuringiensis - Mediated Priming Induces Jasmonate/Ethylene and Salicylic Acid-Dependent Defense Pathways Genes in Tomato Plants
Bacillus thuringiensis Berliner as a biological control agent can play a crucial role in the integrated management of a wide range of plant pests and diseases. B. thuringiensis is expected to elicit plant defensive response through plant recognition of microbe-associated molecular patterns (MAMPs), however, there is little information on the molecular base of induced systemic ...
متن کاملSalicylic acid production in response to biotic and abiotic stress depends on isochorismate in Nicotiana benthamiana.
Salicylic acid (SA) is an important signal involved in the activation of defence responses against abiotic and biotic stress. In tobacco, benzoic acid or glucosyl benzoate were proposed to be precursors of SA. This is in sharp contrast with studies in Arabidopsis thaliana, where SA derives from isochorismate. We have determined the importance of isochorismate for SA biosynthesis in Nicotiana be...
متن کاملPVX-potyvirus synergistic infections differentially alter microRNA accumulation in Nicotiana benthamiana.
In comparison to single infections, co-infection of Nicotiana benthamiana with Potato virus X (PVX) and Potato virus Y (PVY) or Plum pox virus (PPV), resulted in increased systemic symptoms (synergism in pathology). Previous studies have shown that virus infections affected the accumulation of various microRNAs (miRNAs) and miRNA target genes. Our studies revealed that double infection by PVX a...
متن کاملA terpenoid phytoalexin plays a role in basal defense of Nicotiana benthamiana against Potato virus X
Terpenoid phytoalexins function as defense compound against a broad spectrum of pathogens and pests in the plant kingdom. However, the role of phytoalexin in antiviral defense is still elusive. In this study, we identified the biosynthesis pathway of a sesquiterpenoid phytoalexin, capsidiol 3-acetate as an antiviral response against RNA virus Potato Virus X (PVX) in Nicotiana benthamiana. NbTPS...
