Lavandula dentata L., popularly known as lavender, is considered to be a medicinal plant that has great economic potential. The aims of the present study were characterize morphology L. grown in Paraíba do Sul, Rio de Janeiro, Brazil and determine content chemical composition its essential oil. Morphology was determined using optical microscope, digital calliper measuring tape. fresh material c...

Barleria albostellata C.B. Clarke (grey barleria, Acanthaceae) is an indigenous shrub to South Africa and has been relatively understudied. This a valuable medicinal plant with wide spectrum of antibacterial anti-inflammatory activities. Detailed studies on the floral pollen morphology B. are rare. study was conducted observe flower grains using stereomicroscopy scanning electron microscopy (SE...

Multicellular glandular trichomes are epidermal outgrowths characterized by the presence of a head made of cells that have the ability to secrete or store large quantities of specialized metabolites. Our understanding of the transcriptional control of glandular trichome initiation and development is still in its infancy. This review points to some central questions that need to be addressed to ...

Systematic investigation on the family Asteraceae (Compositae) growing throughout in the northern region of Bangladesh was carried out. A total of 36 species under 29 genera of the family Asteraceae were collected and identified. A complete taxonomic account of each species has been given along with their current name, local name, brief description, phenology, basic chromosome number, anatomy a...

We sought to gain insights into the mechanism of resistance of glandular-haired alfalfa to the potato leafhopper, by testing the trichomes of proprietary genotypes for chemical versus morphological differences. Two-choice, noncontact tests were conducted using four glandular-haired and one glabrous genotype of alfalfa, representing a spectrum of resistance, to determine whether adult female lea...

Trichomes are structures that cover the surface of plants with hair-like and found in a large number either unicellular or multicellular forms. one important elements plants, because their presence can be used to identify species based on appearance, size, type, content compounds them protect environment from various kinds pollutants. Road shade planted side road function absorbing The purpose ...

Herbivory can induce several structural and functional alterations in the plant secretory system. Glandular trichomes are the main sites of production of volatile organic compounds (VOCs) with several chemical properties in Lamiaceae species. Ocimum species usually have three morphotypes of glandular trichomes (morphotype I is peltate and has a wide four-celled head; morphotype II is capitate a...

Clavicipitaceous fungi producing ergot alkaloids were recently discovered to be epibiotically associated with peltate glandular trichomes of Ipomoea asarifolia and Turbina corymbosa, dicotyledonous plants of the family Convolvulaceae. Mediators of the close association between fungi and trichomes may be sesquiterpenes, main components in the volatile oil of different convolvulaceous plants. Mol...

Inducible chemical defenses of plants have received much attention in the last three decades, and these defenses often involve trichomes. It is known that some plant secondary metabolites may accumulate in trichomes which can protect plants from damage by herbivores. However, studies on plant trichomes are largely limited to some major vegetable or cash crops and model species with large glandu...
