T-phylloplanin proteins secreted to aerial surfaces of tobacco (Nicotiana tabacum) by short procumbent trichomes inhibit spore germination and blue mold disease caused by the oomycete pathogen Peronospora tabacina. Many other plants were found to contain water-washed leaf surface proteins (phylloplanins), but the functions and properties of these are not known. Here we extend earlier evidence f...

Objective: Effect of medicinal plants on pathogens and disease causing organism are believedto possess good activity against it. The medicinal plant Vitex negundo and Datura metel were studie for analyzing antibacterial effect against Bacterial Cold Water Disease causing organism. Methods: The selected plant leaves were extracted out with following solvent of Hexane Chloroform and Aqueous and t...

Glandular trichomes of many plant species synthesize and secrete a variety of phytochemicals that play an important protective role against pathogens and pests. Acyl sugars, in particular, are powerful natural insecticides. We demonstrated the existence of the α-ketoacid elongation (αKAE) pathway, an alternative to the fatty acid synthase (FAS) pathway, for the extension of carbon chains of acy...

Chilli pepper (Capsicum annum L) is being grown in diverse climatic conditions throughout India. Nonpersistent aphid transmitted viruses have been implicated as the major factor contributing to low yields of chilli pepper in India. A virus causing symptoms of mosaic mottling, vein banding, and leaf distortion of chilli was isolated from chilli growing areas of Karnataka and Tamil Nadu states of...

Chemical investigation of 50% ethanol eluate fraction of macroporous resin for the flower of Datura metel L. collected in Jiangsu province of China resulted in the isolation of two novel naturally occurring norwithasteroids, baimantuoluoline I (1) and baimantuoluoside J (2). Their structures were elucidated as 5 α , 6 β , 12 β -trihydroxy-1-oxo-2-en-ergosta-21,24;22,29-diepoxy-26-carboxylic aci...
