Topical antiinflammatory activity and chemical composition of the epicuticular wax from the leaves of Eugenia beaurepaireana (Myrtaceae)

Brazilian Journal of Pharmaceutical Sciences, 2009
In order to verify the topical antiinflammatory effect of epicuticular wax from leaves of Eugenia beaurepaireana, it was tested in mice croton oil-induced inflammation. Our findings show that topical application of Eugenia beaurepaireana epicuticular wax

Leaf micromorphology and genetic diversity analysis of Iranian Hordeum species using ISSR and SCoT markers

Nordic Journal of Botany, EarlyView.
The genus Hordeum (Poaceae), of the tribe Triticeae, comprises approximately 32 species with substantial potential for barley improvement. Hordeum vulgare is an economically important cereal widely cultivated across diverse environments, from the Arctic to desert and humid regions.

Occurrences of Deposited Polycyclic Aromatic Hydrocarbons in Wax of Plant Leaves Using Laser Scanning Microscopy and Gas Chromatography–Mass Spectrometry

Atmosphere
The knowledge of the deposition fate of ambient polycyclic aromatic hydrocarbons (PAHs) on plant leaves is limited. To fill in this knowledge gap, this study strives to observe the intermolecular complex between the polycyclic aromatic hydrocarbons and ...

Correlation of Leaf Parameters with Incidence of Papaya Ring Spot Virus in Cultivated Papaya and its Wild Relatives

Journal of Horticultural Sciences, 2019
Papaya ring spot virus (PRSV) disease has been the major impediment in papaya cultivation. The disease is transmitted through three aphid vectors and field tolerance towards this disease varies among Carica papaya cultivars as well as within the ...

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

Pest Management Science, EarlyView.
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Hydrophobic trichome layers and epicuticular wax powders in Bromeliaceae [PDF]

American Journal of Botany, 2001
The distinctive foliar trichome of Bromeliaceae has promoted the evolution of an epiphytic habit in certain taxa by allowing the shoot to assume a significant role in the uptake of water and mineral nutrients. Despite the profound ecophysiological and taxonomic importance of this epidermal structure, the functions of nonabsorbent trichomes in remaining

Developmental pattern of grapevine (Vitis vinifera L.) berry cuticular wax: Differentiation between epicuticular crystals and underlying wax.

PLoS ONE, 2021
The grapevine berry surface is covered by a cuticle consisting of cutin and various lipophilic wax compounds. The latter build the main barrier for transpirational water loss and protect the fruit against environmental factors e.g.

Seedling resistance and chemical defenses against Psylliodes chrysocephala: the roles of seed age and sinapinic acid in Sinapis alba and Brassica napus

Pest Management Science, EarlyView.
The cabbage stem flea beetle (Psylliodes chrysocephala) is a major pest of winter oilseed rape (Brassica napus). We tested B. napus and Sinapis alba seedlings for feeding resistance and underlying chemical defenses. S. alba was least damaged, while metabolite profiles revealed resistance‐linked compounds, highlighting breeding potential for insect ...

Birch Leaves as a Minefield: Do Trichomes Mediate Neonate Caterpillar Site Selection?

Entomologia Experimentalis et Applicata, EarlyView.
We investigated whether neonate Drepana arcuata caterpillars select leaf sites based on trichome distribution. Specifically, we assessed where larvae establish on leaves, quantified trichome distribution on leaves, and tested whether neonates avoid leaf trichomes. Neonates preferentially established and fed on areas with fewer trichomes, especially the

Evidence for regulation of transpiration in nonstomatal plants: insights from bryophyte gametophytes

New Phytologist, EarlyView.
Kinetics of cell wall water vapor potential (Ψcw) and resistance of cell wall and plasmatic membrane to water flux in response to cytoplasmic water potential (Ψcyt) during dehydration. Ψcyt was calculated from the WC at any moment of the dehydration curve by using the relationship between −1/Ψw and WC of pressure volume curves and assuming Ψw = Ψcyt ...
