PHELLOGEN ACTIVITY IN ROBINIA PSEUDACACIA L. [PDF]
SummaryPhellogen activity in Robinia pseudacacia and some of the factors controlling it were investigated. A highly active phellogen is characterized by the production of large thin‐walled phellem cells. A layer of flat, thick‐walled phellem cells next to the phellogen characterizes an inactive meristem.

Abstract Larval feeding by the moth genus Ogmograptis (Bucculatricidae: Lepidoptera) creates one of the most iconic features of the Australian bush—the ‘scribbles’ found on smooth‐barked Eucalyptus. The taxonomic history of Ogmograptis has been challenging, with members of the genus being initially described in four different genera representing three ...

Biological Flora of Britain and Ireland: Viscum album
Mistletoe is a charismatic parasite of tree crowns with a long history of folklore and connections with Christmas celebrations. This, and its need for light, helps explain why it is most common in human‐made habitats across Europe. Once thought to benignly take just water and nutrients from its host it is now known to take carbon as well which can lead

TheSHORT-ROOT-like genePtSHR2Bis involved inPopulusphellogen activity [PDF]
SHORT-ROOT (SHR) is a GRAS transcription factor first characterized for its role in the specification of the stem cell niche and radial patterning in Arabidopsis thaliana (At) roots. Three SHR-like genes have been identified in Populus trichocarpa (Pt). PtSHR1 shares high similarity with AtSHR over the entire length of the coding sequence.

Genome‐wide identification, phylogeny, and gene duplication of the epigenetic regulators in Fagaceae
Abstract Epigenetic regulators are proteins involved in controlling gene expression. Information about the epigenetic regulators within the Fagaceae, a relevant family of trees and shrubs of the northern hemisphere ecosystems, is scarce. With the intent to characterize these proteins in Fagaceae, we searched for orthologs of DNA methyltransferases ...

The study confirms the role of Platypus cylindrus as carrier of the emerging pathogen Diplodia corticola in European cork oak forests using a highly specific molecular marker. Abstract BACKGROUND Botryosphaeria canker (causal agent: Diplodia corticola) is considered one of the most important diseases of cork oak (Quercus suber) stands since it ...

What do we know about growth of vessel elements of secondary xylem in woody plants?
ABSTRACT Despite extensive knowledge about vessel element growth and the determination of the axial course of vessels, these processes are still not fully understood. They are usually explained as resulting primarily from hormonal regulation in stems.

Improved plant bioconcentration modeling of pesticides: The role of periderm dynamics
A novel approach is presented, considering the periderm as an active barrier for pesticide uptake into plants to optimize pest control and minimize human exposure to pesticide residues in tuber crops. © 2021 The Authors.

Genetic resistance and tumour morphology in birch infected with Taphrina betulina
Abstract Witches’ broom of birch (Betula spp.) caused by Taphrina betulina is an understudied disease that causes the formation of woody tumours, from which ectopic axillary buds and branches grow to form a broom‐like structure. We have addressed two aspects of this disease using naturally infected mature trees in the field.
