Isolation and characterization of chitinase genes from pitchers of the carnivorous plant Nepenthes khasiana.
The genus Nepenthes represents carnivorous plants with pitcher traps capable of efficient prey capture and digestion. The possible involvement of plant chitinases in this process was studied in Nepenthes khasiana. Two different types of endochitinases were identified in the liquid of closed traps exhibiting substrate specificity for either long chitin polymers or N-acetylglucosamine (GlcNAc) ol...
متن کاملIso-Seq analysis of Nepenthes ampullaria, Nepenthes rafflesiana and Nepenthes × hookeriana for hybridisation study in pitcher plants
Tropical pitcher plants in the species-rich Nepenthaceae family of carnivorous plants possess unique pitcher organs. Hybridisation, natural or artificial, in this family is extensive resulting in pitchers with diverse features. The pitcher functions as a passive insect trap with digestive fluid for nutrient acquisition in nitrogen-poor habitats. This organ shows specialisation according to the ...

این پژوهش با هدف "بررسی وضعیت موجود آموزش عالی مجازی در ایران و راههای توسعه و ارتقای آن " و با روش توصیفی-تحلیلی و پیمایشی صورت پذیرفته است. بررسی اسنادو مدارک موجود در زمینه آموزش مجازی نشان داد تعداد دانشجویان و مقاطع تحصیلی و رشته محل های دوره های الکترونیکی چندان مطلوب نبوده و از نظر کیفی نیز وضعیت شاخص خدمات آموزشی اساتید و وضعیت شبکه اینترنت در محیط آموزش مجازی نامطلوب است.
Induced production of antifungal naphthoquinones in the pitchers of the carnivorous plant Nepenthes khasiana
Nepenthes spp. are carnivorous plants that have developed insect capturing traps, evolved by specific modification of the leaf tips, and are able to utilize insect degradation products as nutritional precursors. A chitin-induced antifungal ability, based on the production and secretion to the trap liquid of droserone and 5-O-methyldroserone, is described here. Such specific secretion uniquely o...
