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.

UnMixta-ing Trichome Development in Tomato [PDF]

The Plant Cell, 2020
The plant leaf epidermis constitutes a critical interface with the environment and consists of a single layer comprising three cell types: stomata, trichomes, and pavement cells. Stomata are pores that regulate gas exchange and transpiration.

Micromorphological character expression of the hybrid Quercus × dysophylla and its parental species (Q. crassifolia and Q. crassipes)

Botan‪ical Sciences, 2017
Background: Hybridization leads to individuals with atypical phenotypes, leading to taxonomic confusion when hybridizing populations are studied. Micromorphological characters may enable taxonomists to discriminate between parental and hybrid categories

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.

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.

Identification of candidate genes affecting Delta9-tetrahydrocannabinol biosynthesis in Cannabis sativa. [PDF]

, 2009
RNA isolated from the glands of a Delta(9)-tetrahydrocannabinolic acid (THCA)-producing strain of Cannabis sativa was used to generate a cDNA library containing over 100 000 expressed sequence tags (ESTs).

Leaf trichomes and foliar chemistry mediate defence against glasshouse thrips; Heliothrips haemorrhoidalis (Bouché) in Rhododendron simsii [PDF]

, 2016
Herbivore defence mechanisms are a costly diversion of resources away from growth and reproduction. Thus time-limited and tissue specific expression in critical plant parts is more efficient as defined by optimal defence theory.

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)

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
