Gene regulatory network analysis of silver birch reveals the ancestral state of secondary cell wall biosynthesis in core eudicots

New Phytologist, Volume 246, Issue 5, Page 2059-2074, June 2025.
Summary The compact genome and lack of recent whole‐genome multiplication (WGM) events make the boreal pioneer tree silver birch (Betula pendula) a promising model for primary and secondary cell wall (PCW and SCW) regulation in forest trees. Here, we constructed regulatory networks through combined co‐expression and promoter motif analysis and carried ...

International Biological Flora: Ceratonia siliqua

Journal of Ecology, Volume 112, Issue 8, Page 1885-1922, August 2024.
The carob tree (Ceratonia siliqua) has a long traditional history in Mediterranean cultures providing food for humans and domestic animals. Its remarkable tolerance of drought, salt and fire, with an ability to thrive in poor, dry soils, makes it ideal for a warming Mediterranean climate.

Oak leaf galls: Neuroterus numismalis and Cynips quercusfolii, their structure and ultrastructure

Acta Societatis Botanicorum Poloniae, 2017
Anatomy and surface ultrastructure of the galls induced on oak leaves by the insects – Neuroterus numismalis (Ol.) and Cynips (Diplolepis) quercusfolii L. – were investigated using a scanning electron microscope (SEM) and a light microscope (LM).

Vascular cambium stem cells: past, present and future

New Phytologist, Volume 243, Issue 3, Page 851-865, August 2024.
Summary Secondary xylem and phloem originate from a lateral meristem called the vascular cambium that consists of one to several layers of meristematic cells. Recent lineage tracing studies have shown that only one of the cambial cells in each radial cell file functions as the stem cell, capable of producing both secondary xylem and phloem.

Drought increases Norway spruce susceptibility to the Eurasian spruce bark beetle and its associated fungi

New Phytologist, Volume 242, Issue 3, Page 1000-1017, May 2024.
Summary Drought affects the complex interactions between Norway spruce, the bark beetle Ips typographus and associated microorganisms. We investigated the interplay of tree water status, defense and carbohydrate reserves with the incidence of bark beetle attack and infection of associated fungi in mature spruce trees.

Bark structure is coordinated with xylem hydraulic properties in branches of five Cupressaceae species

Plant, Cell &Environment, Volume 47, Issue 5, Page 1439-1451, May 2024.
Abstract The properties of bark and xylem contribute to tree growth and survival under drought and other types of stress conditions. However, little is known about the functional coordination of the xylem and bark despite the influence of selection on both structures in response to drought.

Lignin composition and structure differs between xylem, phloem and phellem in Quercus suber L.

Frontiers in Plant Science, 2016
The composition and structure of lignin in different tissues - phellem (cork), phloem and xylem (wood) - of Quercus suber was studied. Whole cell walls and their respective isolated milled lignins were analyzed by pyrolysis coupled with gas ...

A detailed anatomical approach to taxonomically problematic endemic Seseli L. (Apiaceae) taxa in Türkiye

Microscopy Research and Technique, Volume 87, Issue 4, Page 800-807, April 2024.
Vegetative anatomical characters help to illuminate the taxonomy in endemic thrSeseli taxa from Apiaceae family in Türkiye. In this way, the similarities in the studied taxa support the latest molecular studies. Abstract In this study, the vegetative anatomical features of the taxa, which were previously named as Seseli gummiferum subsp.

Secondary Aerenchyma Formation and its Relation to Nitrogen Fixation in Root Nodules of Soybean Plants (Glycine max) Grown under Flooded Conditions

Plant Production Science, 2002
Soybean (Glycine max (L.) Merr.) is considered to be susceptible to flooding, a major agronomic problem in the world, and nitrogenase activity rapidly declines due to oxygen deficiency in root nodules.
