Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

Journal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Spatial distribution of trichomes in tea plants (Camellia sinensis) and their adaptation to drought and shading

Scientia Horticulturae
Trichomes in plants serve not only to secrete secondary metabolites and defend against biotic and abiotic stresses, but also influence the quality of processed products in species such as tea plants (Camellia sinensis). However, the distribution patterns

Is there a role for cannabidiol in obesity, metabolic syndrome and binge eating?

British Journal of Pharmacology, EarlyView.
Cannabidiol (CBD) is one of the most abundant phytocannabinoids isolated from the Cannabis sativa plant. CBD is a lipophilic, non‐intoxicating substance that differently from Δ9‐tetrahydrocannabinol (Δ9‐THC) does not present the typical profile of a drug of abuse.

Ultrastructural changes in potato (Solanum tuberosum) under NaCl mediated salinity stress in vitro

Advances in Horticultural Science, 2016
Histological analysis was employed to investigate the way potato plants (Solanum tuberosum cv. Draga and Spunta) face salinity stress. Different concentrations of NaCl (50, 100, 150, 200 and 250 mM) were used on potato plantlets growing in vitro to ...

Evolutionary framework and tribal circumscription of Amaranthaceae sensu stricto based on a comprehensive phylogenomic analysis

Cladistics, EarlyView.
Abstract The evolutionary history of Amaranthaceae sensu stricto (s.s.) has been shaped by multiple whole‐genome duplications and rapid radiations, producing an ecologically diverse lineage whose internal relationships have long remained unresolved.

Attractiveness of Melon Genotypes to Whitefly (Bemisia tabaci) Mediated by Foliar Morphological and Biochemical Traits

Entomologia Experimentalis et Applicata, EarlyView.
This study identifies melon genotypes resistant to Bemisia tabaci by integrating morphological and biochemical leaf traits. Using free‐choice and no‐choice assays, we demonstrate that resistance is primarily mediated by antixenosis. Genotypes CNPH 11‐1071‐43, CNPH 06‐1047‐343, CNPH 13‐1076, and BG MEL 16 significantly reduced whitefly settling and ...

Intergeneric Comparison of Staminal Trichomes in the Tribe Ipomoeeae (Convolvulaceae)

Plants
Hairs or trichomes distributed on the base of filaments in the morning glory family, known as staminal trichomes, differ from those found on other plant parts and have been recognized for their taxonomic value for over a century.

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

Trichomes as a defense mechanism against climbing plants

Plant Signaling & Behavior
Non-glandular trichomes are essential in plant defence against herbivores and water loss. However, evolutionary pressures often favor the development of multifunctional traits, suggesting that trichomes may serve multiple ecological roles. I hypothesized
