Essential Oil Composition and Glandular Trichome Structure of the Weather Prophet Dimorphoteca pluvialis

Biology and Life Sciences Forum, 2023
Dimorphoteca pluvialis (L.) Moench, usually known as weather prophet, African daisy, or Cape marigold, is an Asteraceae commonly found in gardens due to its appealing white to yellowish flowers.

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 ...

The foliar trichomes of Hypoestes aristata (Vahl) Sol. ex Roem. & Schult var aristata (Acanthaceae) a widespread medicinal plant species in tropical sub-Saharan Africa: with comments on its possible phylogenetic significance

Biological Research, 2010
The micromorphology of foliar trichomes of Hypoestes aristata var. aristata was studied using stereo, light and scanning microscopy (SEM). This genus belongs to the advanced angiosperm family Acanthaceae, for which few micromorphological leaf studies ...

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.

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 ...

A Comparative Analysis of Leaf Trichomes in Diploid and In Vitro-Induced Tetraploid Patchouli (Pogostemon cablin Benth.)

Journal of Experimental Life Science
This study aimed to analyze the types, sizes, numbers, and densities of leaf trichomes in in vitro–induced tetraploid patchouli (Pogostemon cablin Benth.) plants and their diploid counterparts.

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

Identification of non‐glandular trichome hairs in cannabis using vision‐based deep learning methods

Journal of Forensic Sciences
AbstractThe detection of cannabis and cannabis‐related products is a critical task for forensic laboratories and law enforcement agencies, given their harmful effects. Forensic laboratories analyze large quantities of plant material annually to identify genuine cannabis and its illicit substitutes.

α‐1,3‐Glucan Is Required for Cell Wall Integrity and Full Virulence of Colletotrichum graminicola, but Not for Evasion of PAMP‐Triggered Immunity

Molecular Microbiology, EarlyView.
Abbreviated Summary The role of the major fungal cell wall polymer α‐1,3‐glucan in plant infection is poorly understood. Deletion mutants of the maize anthracnose fungus Colletotrichum graminicola lacking all three α‐1,3‐glucan synthase genes differentiated severely distorted biotrophic hyphae in planta, and virulence was strongly reduced.
