Organogenesis and transient genetic transformation of the hybrid Eucalyptus grandis × Eucalyptus urophylla Organogênese e transformação genética transiente do híbrido Eucalyptus grandis × Eucalyptus urophylla

Scientia Agricola, 2011
The hybrid Eucalyptus grandis x Eucalyptus urophylla presents high levels of productivity and potential for use in paper, cellulose and fiber industries. The bud organogenesis from leaf explants of two clones of E. grandis × E. urophylla was studied in order to verify the effect of several factors: subculture duration on multiplication medium, type of ...

First line of defence: Eucalyptus leaf waxes influence infection by an aggressive fungal leaf pathogen

Plant Biology, Volume 27, Issue 5, Page 924-932, August 2025.
Leaf wax compounds of Eucalyptus modulate the germination and infection of the leaf blight pathogen Teratosphaeria destructans. Abstract Leaf epicuticular waxes provide important anatomical and chemical defences against fungi that infect leaves. In this study we analysed the leaf wax composition of Eucalyptus grandis × Eucalyptus urophylla hybrids with

Functional variability of two lignification genes in Eucalyptus urophylla [PDF]

BMC Proceedings, 2011
Lignin quantity and composition are major components of wood quality in eucalypts breeding programs. Optimizing these traits can have a huge economical impact for charcoal and pulp production. However, little is known about the genetic determinism of these traits.

Do Eucalypt Species Display Similar Potential Niche Patterns to North American Trees?

Austral Ecology, Volume 50, Issue 7, July 2025.
ABSTRACT A 2024 paper in Science described the realised and potential thermal niches of 188 North American tree species in terms of mean annual temperature (MAT). Using PlantSearch data from outside species‐native distributions, it was found that species potential niches displayed a ‘centrifugal organisation’ of thermal niches.

Land‐Use Change Enhances Organic Phosphorus Pools in Oxisols in Brazil's New Agricultural Frontier

Soil Use and Management, Volume 41, Issue 3, July‐September 2025.
ABSTRACT Land‐use types and management systems can affect the availability of phosphorus (P) by modifying its compartments. The aim of this study was to evaluate the organic and inorganic fractions of P in an Oxisol in the Cerrado region of Brazil, considering various land‐use types and management systems and the period of application.

No Direct Observational Evidence for Basidiospore‐Derived Infection of Eucalypt and Rose Apple (Syzygium jambos) by the Myrtle Rust Pathogen, Austropuccinia psidii, From Brazil

Forest Pathology, Volume 55, Issue 3, June 2025.
ABSTRACT Myrtle rust caused by Austropuccinia psidii is one of the most important diseases affecting eucalypts (Eucalyptus spp. and Corymbia spp.) in Brazil. Asexual spores of the myrtle pathogen, urediniospores, give rise to infection of young tissues (e.g., leaf, stem, flower and fruit) of the myrtaceous hosts.
