Diseases caused by plant viruses are widespread, resulting in severe economic losses worldwide. Understanding the cellular basis of defense responses and developing efficient diagnostic tools for early recognition of host specificity to viral infection is, therefore, of great importance. In this
The potassium pyroantimonate (KPA) Ca(2+) precipitation technique, X-ray microanalysis and Electron Energy Loss Spectroscopy carried out by transmission electron microscopy were used to analyze the Ca(2+) distribution in Catharanthus roseus L. leaves infected with phytoplasmas belonging to different
Transport of inorganic orthophosphate (Pi) across the tonoplast membrane was studied using intact vacuoles isolated from suspension-cultured cells of Catharanthus roseus. Orthophosphate uptake was strongly stimulated in the presence of Mg-ATP and Mg-pyrophosphate and inhibited by bafilomycin and
Experiments were carried out in a greenhouse to determine the effect of fertilizer concentration (0, 0.5, 1.0, and 2.0× Hoagland solutions) and various commercial biopesticides on the severity of Phytophthora nicotianae infection of Madagascar periwinkle. Application of biopesticides and fertilizer
BACKGROUND
Catharanthus roseus (L). Don (Catharanthus roseus) is a traditional anti-diabetic herb widely used in many countries, and the alkaloids of Catharanthus roseus are considered to possess hypoglycemic ability.
OBJECTIVE
To systematically investigate the potential anti-diabetic effects and
The effects of exogenous trehalose (Tre) on salt tolerance of pharmaceutical plant Catharanthus roseus and the physiological mechanisms were both investigated in this study. The results showed that the supplement of Tre in saline condition (250 mM NaCl) largely alleviated the inhibitory effects of
