EucaMOD: a comprehensive multi-omics database for functional genomics research and molecular breeding of fast-growing eucalyptus trees. [PDF]

Plant J
Significance Statement As eucalyptus research increasingly relies on big data, scientists have lacked a modern, integrated platform for multi‐omics analysis. We present a comprehensive eucalyptus multi‐omics database and analysis platform (EucaMOD) that unifies genomic, transcriptomic, and epigenomic data for 39 species, providing a vital resource to ...

Soil Nutrient Availability Drives Fungal Community Structure and Function During the Transformation of Eucalypt Plantations Logging Sites in Southern China. [PDF]

Ecol Evol
Highly intensive eucalyptus plantation management has led to an imbalance of nutrients in the forest land, which has seriously weakened the self‐healing capacity of the ecosystem. Therefore, it is urgent to restore the soil quality of logging sites in multi‐generation continuous plantations. Soil microorganisms, especially fungi, play an important role

A Newly Identified Passive Hyperaccumulator Eucalyptus grandis × E. urophylla under Manganese Stress. [PDF]

PLoS One, 2015
Manganese (Mn) is an essential micronutrient needed for plant growth and development, but can be toxic to plants in excess amounts. However, some plant species have detoxification mechanisms that allow them to accumulate Mn to levels that are normally toxic, a phenomenon known as hyperaccumulation.

Drying Characteristics of Eucalyptus urophylla × E. grandis with Supercritical CO2 [PDF]

Materials, 2020
Supercritical CO2 (ScCO2) is a drying medium with excellent solubility and mass transfer efficiency. Supercritical CO2 drying (SCD) can remove the water of wood rapidly and prevent a change of microstructure caused by capillary tension in the drying process. In this study, Eucalyptus urophylla × E.

Consequências da deriva de clomazone e sulfentrazone em clones de E. grandis x E. urophylla Consequences of clomazone and sulfentrazone drift on clones of E. grandis x E. urophylla [PDF]

Revista Árvore, 2009
Este trabalho teve por objetivo estudar os efeitos de deriva simulada dos herbicidas clomazone e sulfentrazone em dois clones comerciais de E. grandis x E. urophylla, da Votorantim Celulose e Papel (VCP1 e VCP2). Na simulação, as doses do herbicida clomazone variaram de 0 a 2.000 mL ha-1 e no sulfentrazone, de 0 a 1.500 mL ha-1.

Improved Estimates of Biomass Expansion Factors and Root-To-Shoot Ratios: An Approach for Different Forest Types Across a Climatic Gradient in Brazil. [PDF]

Glob Chang Biol
This paper addresses the global greenhouse gas inventory challenge by reducing uncertainty and enabling more reliable carbon accounting to support strategic and policy decision‐making under climate variability. ABSTRACT Advancements in the current state of the art of the key drivers of biomass expansion factor (BEF) and the root‐to‐shoot ratio (R) are ...
