Quantification of variability in trichome patterns [PDF]

Frontiers in Plant Science, 2014
While pattern formation is studied in various areas of biology, little is known about the noise leading to variations between individual realizations of the pattern. One prominent example for de novo pattern formation in plants is the patterning of trichomes on Arabidopsis leaves, which involves genetic regulation and cell-to-cell communication.

Micromorpho‐anatomical studies on the leaves and woods of Turkish Daphne (Thymelaeaceae) taxa

Nordic Journal of Botany, EarlyView.
The identification of Daphne taxa is difficult because of the lack of available morphological characteristics. Here, we aimed to describe leaf and wood micromorpho‐anatomical characteristics of native Turkish Daphne taxa (D. glomerata, D. gnidioides, D. mezereum, D. mucronata, D. oleoides subsp. kurdica, D. pontica and D.

A Highly Efficient System for Separating Glandular and Non-glandular Trichome of Cucumber Fruit for Transcriptomic and Metabolomic Analysis

Bio-Protocol
Cucumber (Cucumis sativus) trichomes play a critical role in resisting external biological and abiotic stresses. Glandular trichomes are particularly significant as they serve as sites for the synthesis and secretion of secondary metabolites, while non ...

Generic limits of the Rhyparini with respect to the genus Termitodius Wasmann, 1894 (Coleoptera: Scarabaeidae: Aphodiinae) [PDF]

, 2009
Three distinct tibial types are recognized within the Rhyparini (Scarabaeidae, Aphodiinae). Based on this, generic limits for the species of Termitodius Wasmann are reevaluated, with the Old World members being transferred to Termitodiellus Nakane.

Mutations in UDP-Glucose:Sterol Glucosyltransferase in Arabidopsis Cause Transparent Testa Phenotype and Suberization Defect in Seeds [PDF]

, 2009
In higher plants, the most abundant sterol derivatives are steryl glycosides (SGs) and acyl SGs. Arabidopsis (Arabidopsis thaliana) contains two genes, UGT80A2 and UGT80B1, that encode UDP-Glc:sterol glycosyltransferases, enzymes that catalyze the ...

Trichome morphogenesis: a cell–cycle perspective [PDF]

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2002
Arabidopsis leaf hairs (trichomes) are polyploid epidermal cells with a predictable branching pattern. More than 15 genes have been identified that are involved in the regulation of branching. The cloning of theZWICHEL,ANGUSTIFOLIAandSTICHELgenes points to two mechanistic aspects of branch formation: (i) a role of the microtubule cytoskeleton; and (ii)

Two new records for the flora of Paraguay: Stemodia diplohyptoides and S. lobelioides (Plantaginaceae:Gratioleae)

Nordic Journal of Botany, EarlyView.
Stemodia diplohyptoides M.M.Sosa & Dematt. and S. lobelioides Lehm. (Gratioleae, Plantaginaceae) are reported for the first time in Paraguay, found in Alto Paraná and Presidente Hayes departments, respectively. These new records extend the known geographical range of both species, representing the northern records to date, S.

Roles of trichomes with silica particles on the surface of leaves in Aphananthe aspera

AIP Advances, 2013
There exist many trichomes with silica particles on the surface of leaves in Aphananthe aspera (Muku tree). The size of the trichomes is on the order of some tens to hundreds of micrometers.

Taxonomic treatment, geographic distribution and preliminar conservation status of Croton sect. Barhamia subsect. Barhamia (Euphorbiaceae) in Brazil

Nordic Journal of Botany, EarlyView.
The genus Croton (Euphorbiaceae) is an exceptionally megadiverse genus, encompassing roughly 1200 species that are predominantly distributed across tropical regions globally. For the New World, the genus is organized into three subgenera (Adenophylli, Geiseleria and Quadrilobi) and 31 sections, with C. sect. Barhamia standing out with its approximately
