Modeling eccentric growth explicitly to investigate intra-annual drivers of xylem cell production using xylogenetic data

Forest Ecosystems
Xylogenesis, the process through which wood cells are formed, results in the long-term storage of carbon in woody biomass, making it a key component of the global carbon cycle.

THE ANTIOXIDANT ENZYMES – INDICATORS OF DIFFERENT XYLOGENESIS SCENARIOS: IN EARLY ONTOGENY AND IN ADULT PLANTS (EXAMPLE OF BETULA PENDULA ROTH)

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2018
We studied the activity of antioxidant enzymes (superoxide dismutase (SOD), catalase (CAT), peroxidase (POD)) and polyphenol oxidase (PPO) across ontogenetic stages during the formation of normal (in silver birch, Betula pendula Roth var.

Integrated analysis and transcript abundance modelling of H3K4me3 and H3K27me3 in developing secondary xylem

Scientific Reports, 2017
Despite the considerable contribution of xylem development (xylogenesis) to plant biomass accumulation, its epigenetic regulation is poorly understood. Furthermore, the relative contributions of histone modifications to transcriptional regulation is not ...

Endogenous oscillations of electric potential difference in the cambial region of the pine stem. II. Possible involvement of the oscillations in xylogenesis

Acta Societatis Botanicorum Poloniae, 2014
Direct and indirect interrelations between xylogenic processes and the endogenous electric potential difference (PD) oscillations generated in the cambial region of isolated tissue blocks from pine trunks were investigated.

Duration of xylogenesis in black spruce lengthened between 1950 and 2010 [PDF]

Annals of Botany, 2012
Reconstructions have identified the 20th century as being uniquely warm in the last 1000 years. Changes in the phenology of primary meristems converged toward increases in length of the growing season. Has the phenology of secondary meristem changed during the last century, and to what extent?Timings of wood formation in black spruce, Picea mariana ...

Glucuronoyl Esterase of Pathogenic Phanerochaete carnosa Induces Immune Responses in Aspen Independently of Its Enzymatic Activity

Plant Biotechnology Journal, Volume 24, Issue 2, Page 602-619, February 2026.
ABSTRACT Microbial enzymes expressed in plants add new functionalities but occasionally trigger undesirable immune responses. Phanerochaete carnosa glucuronoyl esterase (PcGCE) hydrolyses the bond between lignin and 4‐O‐methyl‐α‐D‐glucuronic acid substituent of glucuronoxylan.

Wood formation in Norway spruce on a lowland site in Slovenia in 2015 and comparison with other conifers all over Europe

Les, 2017
We present xylem formation in Norway spruce (Picea abies (L.) Karst.) in 2015 at Panška reka, near Ljubljana, Slovenia (ca. 46°00’N, 14°40’E, 400 m a.s.l.) with a temperate climate.

Allies or Enemies: The Role of Reactive Oxygen Species in Developmental Processes of Black Cottonwood (Populus trichocarpa)

Antioxidants, 2020
In contrast to aboveground organs (stems and leaves), developmental events and their regulation in underground organs, such as pioneer and fine roots, are quite poorly understood.

Molecular Genetic Characteristics of Different Scenarios of Xylogenesis on the Example of Two Forms of Silver Birch Differing in the Ratio of Structural Elements in the Xylem

Plants, 2021
Silver birch (Betula pendula Roth) is an economically important species in Northern Europe. The current research focused on the molecular background of different xylogenesis scenarios in the birch trunks. The study objects were two forms of silver birch,

Xylogenesis under climatic stress: wood anatomical evidence of harsh conditions

Les
Xylogenesis – the process of secondary xylem formation – is tightly regulated by hormonal, physiological, and environmental signals, but becomes highly vulnerable under extreme climatic stress.
