Steviol glycosides are found in high concentrations in the leaves of the Paraguayan perennial herb Stevia rebaudiana and their intense sweetness, as well as high concentration in Stevia leaf tissue, has made them the subject of research interest for over 100 years. Steviol glycosides are diterpenoids whose biosynthetic pathways share four steps in common… (More)
The sweet diterpenoid glycoside, rebaudioside F, was isolated from leaves of a high rebaudioside C producing line of Stevia rebaudiana, and its structure was established by chemical and spectral studies.
Compatible virus infection induces and suppresses host gene expression at the global level. These gene-expression changes are the molecular basis of symptom development and general stress and defence-like responses of the host. To assess transcriptional changes in soybean plants infected with soybean mosaic virus (SMV), the first soybean trifoliate leaf,… (More)
Induction of specific immunological unresponsiveness by feeding protein antigens is termed oral tolerance and may be a potential therapy for autoimmune diseases. Whereas oral tolerance therapy may be both simple and effective, the requirement for large amounts of protein will limit clinical testing of autoantigens, which are difficult to produce. We have… (More)
Interleukin-4 (IL-4) is a pleiotropic cytokine that plays a key regulatory role in the immune system. Recombinant human IL-4 (rhIL-4) offers great potential for the treatment of cancer, viral and autoimmune diseases. Unfortunately, the high production cost of IL-4 associated with conventional expression systems has, until now, limited broader clinical… (More)
Six new labdane-type, non-glycosidic diterpenes, sterebins I-N (1-6), were isolated from the leaves of Stevia rebaudiana. Their structures, analogous to those of the previously described sterebins A-H, were elucidated on the basis of spectroscopic and chemical studies.
The development of novel strategies against plant viral diseases relies on a better understanding of molecular virus-host interactions. Here, we report an easy, efficient and reproducible protocol for Arabidopsis protoplast isolation and transfection to study the infection and replication of a potyvirus, Plum pox virus (PPV). Macerozyme and cellulose were… (More)
