Xanthones from the herb of Swertia elata and their anti-TMV activity [PDF]

Natural Product Research, 2015
Two new xanthones (1–2), together with four known ones (3–6), were isolated from whole herb of Swertia elata. Their structures were elucidated by spectroscopic methods including extensive 1D- and 2D-NMR techniques. Their anti-tobacco mosaic virus (anti-TMV) activity test revealed that 1–6 showed weak anti-TMV activities with inhibition rate in the ...

The Pathogenesis-Related Protein 4b Induced by Rice Stripe Virus Enhances Host's Antiviral Defence. [PDF]

Mol Plant Pathol
OsPR4b is induced by RSV to inhibit viral infection via regulating RNA metabolism and cell wall reinforcement, while its knockdown modulates NAC/MYB/ERF/WRKY family genes and enhances viral accumulation. ABSTRACT Rice stripe virus (RSV) causes rice stripe disease, which poses a serious threat to rice production.
