Leaf Anatomical and Morphological Characteristics of some Species of Quercus, Fagus, and Castanea (Fagaceae) from some Habitats in Iran [PDF]

open access: yesتاکسونومی و بیوسیستماتیک, 2019
The Fagaceae family is comprised of 8 genera with over 1000 different species. Despite many advances in understanding phylogenetic relationships based on molecular data, the existence of hybrids and/or the presence of ambiguous sequences justify careful ...

The influences of elevated carbon dioxide on trichome densities and trichome molecular pathways [PDF]

open access: yes, 2020
Leaf hairs (trichomes; Fig. 1) are small and rigid epidermal structures that serve in herbivore defense, temperature regulation, boundary layer fortification, and UV-B protection, and can even act as mechanosensory switches indicating insect herbivore ...

Altered stomatal patterning accompanies a trichome dimorphism in a natural population of Arabidopsis

open access: yesPlant Direct, 2020
Trichomes are large epidermal cells on the surface of leaves that are thought to deter herbivores, yet the presence of trichomes can also negatively impact plant growth and reproduction.

RrTTG1 promotes fruit prickle development through an MBW complex in Rosa roxburghii

open access: yesFrontiers in Plant Science, 2022
Fruit prickles are widely distributed on the pericarp and exhibit polymorphic traits at different developmental stages. Although they are multicellular appendages that are well-known for helping plants defend against biotic and abiotic stresses, their ...

The Effectiveness of Physical and Chemical Defense Responses of Wild Emmer Wheat Against Aphids Depends on Leaf Position and Genotype

open access: yesFrontiers in Plant Science, 2021
The bird cherry-oat aphid (Rhopalosiphum padi) is one of the most destructive insect pests in wheat production. To reduce aphid damage, wheat plants have evolved various chemical and physical defense mechanisms.
