Genetic Distinctiveness Highlights the Conservation Value of a Sicilian Manna Ash Germplasm Collection Assigned to Fraxinus angustifolia (Oleaceae)

2020

The cosmopolitan genus Fraxinus comprises about 40 species occupying several habitats in the Northern Hemisphere. With some species hybridizing and sharing genetic variants, questions remain on the species assignment of germplasm within the genus Fraxinus despite numerous species-specific assessments. A multidisciplinary approach was employed to provide a definitive insight into the genetics of an endangered Fraxinus &ldquo

An Investigation of the Seasonal Pattern of Mannitol Content in Deciduous and Evergreen Species of the Oleaceae Growing in Northern Sicily

2002

In several species of the Oleaceae, mannitol, already present at considerable levels, accumulates in response to stress. This family comprises both deciduous and evergreen species, and we investigated the role of mannitol in deciduous malacophyll and evergreen sclerophyll species growing under the same conditions in the field. The relationship between mannitol content and changes in rainfall or temperature was also studied. The mannitol content of leaves of Fraxinus ornus L., F. angustifolia Vahl., Olea europaea L. and Phillyrea media L. was determined by gas chromatography. Leaf samples were collected once a month for 1 year. In the two ash species, the seasonal pattern of mannitol content…

Lectotypification of Three Linnaean Names in the GeneraPhillyreaandFraxinus(Oleaceae)

2014

Lectotypes for the Linnaean names Phillyrea angustifolia, P. media and Fraxinus ornus (Oleaceae), are designated from original material conserved in LINN (Linnaean Herbarium) and BM (George Clifford Herbarium). A specimen at BM is designated here as the second-step lectotype of the name Fraxinus ornus.

Seasonal pattern of mannitol and malate accumulation in leaves of two manna ash species (Fraxinus ornusL. andF. angustifoliaVahl) growing in Sicily

2002

ABSTRACT The content of mannitol and malate was assayed enzimatically during spring, summer and autumn, in leaves of two species of ash, Fraxinus ornus L. and Fraxinus angustifolia Vahl, traditionally cultivated in Sicily for the extraction of manna. Both species contain high levels of mannitol and show, on a dry weight basis, a 65–80% increase in the summer content of this polyol. The malate content differs in the two species: in F. ornus it shows a summer increase, but it is relatively low (65–115 µmol g-1 DW), while in F. angustifolia it is higher (275–318 µmol g-1 DW), but remains more or less constant throughout the year. The results suggest that in these species, under the local field…
