Two Decades of the Immersiporthe knoxdaviesiana (Cryphonectriaceae) Canker Outbreak Driven by Clonal Pathogen Lineages

Plant Pathology, Volume 75, Issue 5, September‐October 2026.
A single clonal lineage has driven Cape beech canker for nearly two decades. However, the fungus was also found in healthy trees, suggesting that this emerging disease may have a more complex origin than a simple pathogen introduction. ABSTRACT Immersiporthe knoxdaviesiana (Cryphonectriaceae) causes an aggressive canker disease on native Myrsine ...

Seasonal activity of uridine 5'-diphosphoglucose:coniferyl alcohol glucosyltransferase in relation to cambial growth and dormancy in conifers

, 1998
Uridine 5'-diphosphoglucose:coniferyl alcohol glucosyltransferase (CAGT), the enzyme catalyzing synthesis of coniferin from coniferyl alcohol and uridine 5'-diphosphoglucose, was investigated throughout an annual cycle of cambial growth and dormancy in ...

GA20ox orchestrates distinct roles in cambium and xylem development via gibberellin and auxin signaling in poplar

Industrial Crops and Products
Gibberellin 20-oxidase (GA20ox) is a key enzyme of gibberellin (GA) biosynthesis. Its involvement during secondary growth in trees is incompletely understood.

Cambial dormancy lasts 9 months in a tropical evergreen species

, 2016
Key message: Cambial dormancy in a tropical evergreen species is long lasting, and the initiation of cambial activity is related to day length. Abstract: Studies on cambial activity allow us to understand the growth dynamics of plants.

Growth-regulating factor 15-mediated vascular cambium differentiation positively regulates wood formation in hybrid poplar (Populus alba × P. glandulosa)

Frontiers in Plant Science
IntroductionHybrid poplars are industrial trees in China. An understanding of the molecular mechanism underlying wood formation in hybrid poplars is necessary for molecular breeding.

Defining cambial activity: the limitations of indirect indicators and the need for direct cellular markers

The vascular cambium is a key lateral meristem responsible for secondary growth in woody plants, producing secondary xylem and phloem. Understanding its activity is crucial for studies on plant phenology, carbon sequestration, and environmental responses.

Effect of isolation of bark on cambial activity and development of xylem and phloem in Trembling Aspen

, 1967
Circular patches of bark were surgically isolated on the sides of trembling aspen (Populus tremuloides Michx.) trees at breast height at various times during the dormant and growing seasons. Subsequently, samples of wood and attached bark were taken from

A problemática do risco cambial na importação estudo de caso: Empresas Importadoras de Automóveis em Cabo Verde [PDF]

, 2013
A problemática do risco cambial surge a partir do momento em que agentes económicos decidem efectuar as suas transacções internacionais em divisas. Neste contexto, a necessidade de conhecer e compreender o mercado cambial é peremptório.
