A novel secondary metabolite from the Eucalyptus pathogen Mycosphaerella cryptica [PDF]

, 2009
The most abundant metabolite of the eucalyptus leaf spot pathogen Mycosphaerella cryptica was extracted from agar cultures. The structure of the compound was elucidated by detailed studies of NMR and MS data and by comparison with derivatives.

Two new anamorphs of Mycosphaerella associated with foliar lesions of Eucalyptus dunnii [PDF]

, 2005
Eucalyptus dunnii is a fast growing eucalypt species that has recently been propagated in plantations in southern Queensland. Mycosphaerella species and their anamorphs are commonly associated with foliar lesions in these plantations. Mycosphaerella is a

Spacing effects and seed-lot contrasts in field-expressed foliar necrosis, survival, and growth of Eucalyptus nitens in a Nelder genetic trial under Atlantic sanitary conditions

Frontiers in Forests and Global Change
IntroductionGenetic trials can provide comparative evidence on host performance under shared field exposure that is relevant to forest health surveillance, yet field evidence linking early foliar damage, spacing, and later plantation performance remains ...

Movement of Phaeophleospora destructans throughout Asia; a threat to Australian native forests [PDF]

, 2005
Eucalypts are highly favored plantation species in Asia as they are fast growing and easy to cultivate. Phaeophleospora destructans causes leaf blight that leads to premature defoliation, reduced growth and vigour, and in some instances tree death within

Temperature changes resistance of Eucalyptus marginata to Phytophthora cinnamomi [PDF]

, 1997
Eucalyptus marginata (Jarrah) varies in its resistance to infection by the introduced pathogen, Phytophthora cinnamomi. This trait has been exploited to yield jarrah clones ranging in resistance to P. cinnamomi. However, isolates of P.

Variable number of tandem repeat markers in the genome sequence of Mycosphaerella fijiensis, the causal agent of black leaf streak disease of banana (Musa spp) [PDF]

, 2010
. We searched the genome of Mycosphaerella fijiensis for molecular markers that would allow population genetics analysis of this plant pathogen. M. fijiensis, the causal agent of banana leaf streak disease, also known as black Sigatoka, is the most ...

Eucalyptus oleosa Essential Oils: Chemical Composition and Antimicrobial and Antioxidant Activities of the Oils from Different Plant Parts (Stems, Leaves, Flowers and Fruits) [PDF]

, 2011
Essential oils obtained by hydrodistillation from the different parts (stems, adult leaves, immature flowers and fruits) of Eucalyptus oleosa were screened for their antioxidant and antimicrobial properties and their chemical composition. According to GC-
