This study was aimed to develop of complete microscopy and macroscopy of Tridex procumbens in which the leaves, petioles, roots and stems were studied. Tridex procumbens Linn. Fam. Asteraceae commonly known as ‘Coat Buttons’ is an important plant used against various activities in indigenous system of medicine such as hepatoprotective, antihepatotoxic, antipyretics, anti-diabetic, blood coagula...

Type A glandular trichomes of the wild potato (Solanum berthaultii Hawkes) entrap insects by rapidly polymerizing the trichome contents after breakage by insect contact. Polymerization of trichome exudate appears to be driven by a soluble polyphenol oxidase (PPO). PPO constitutes up to 70% of the protein in individually collected trichomes and reaches a concentration approaching 200 mum in thes...

The biosynthetic route for epoxyangelate esters of the sesquiterpene lactones (STL) uvedalin and enhydrin from in vitro cultures of Smallanthus sonchifolius (Asteraceae) was investigated with (13)C-precursors for the first time in the literature. Photomicroscope analyses and studies using MALDI-MS imaging confirmed that glandular trichomes accumulate STL.

In this study, the micromorphology of vegetative and reproductive structures endemic Centaurea glaberrima Tausch subsp. divergens (Vis.) Hayek (Asteraceae), using scanning electron microscope (SEM), is presented for first time. Uniseriate whip-like non-glandular biseriate glandular trichomes are found on surface all aboveground parts (stem, leaves, peduncles, involucral bract). On adaxial leaf ...

In natural habitats plants can be exposed to brief and light contact with neighbouring plants. This mechanical stimulus may represent a cue that induces responses to nearby plants. However, little is known about the effect of touching on plant growth and interaction with insect herbivores. To simulate contact between plants, a soft brush was used to apply light and brief mechanical stimuli to t...

The Vitaceae genus Causonis is found in tropical to temperate climates from Asia Australia, including the Pacific Islands. Rafinesque established 1930; however, Süssenguth classified it under Cayratia as a sect. Discypharia 1953. was resurrected 2013 using morphological and genetic evidence. We herein provided insight into diversity of trichomes’ micromorphology selected species this recently r...
