Endophytic and pathogenic Phyllosticta species, with reference to those associated with Citrus Black Spot
We investigated the identity and genetic diversity of more than 100 isolates belonging to Phyllosticta (teleomorph Guignardia), with particular emphasis on Phyllosticta citricarpa and Guignardia mangiferae s.l. occurring on Citrus. Phyllosticta citricarpa is the causal agent of Citrus Black Spot and is subject to phytosanitary legislation in the EU. This species is frequently confused with a ta...
متن کاملRapid microwave-assisted hydrolysis for determination of ginkgo flavonol glycosides in extracts of Ginkgo biloba leaves.
A rapid microwave-assisted hydrolysis (MAH) method is presented for the sample pretreatment of the determination of ginkgo flavonol glycosides in extracts of Ginkgo biloba L. (EGb). By this method, flavonol glycosides can be completely hydrolyzed within 2 min. After investigating the effects of solvents, acidity, microwave power, and microwave radiation time on hydrolysis, the optimal hydrolysi...
متن کاملFirst report of Phyllosticta citricarpa and description of two new species, P. paracapitalensis and P. paracitricarpa, from citrus in Europe
The genus Phyllosticta occurs worldwide, and contains numerous plant pathogenic, endophytic and saprobic species. Phyllosticta citricarpa is the causal agent of Citrus Black Spot disease (CBS), affecting fruits and leaves of several citrus hosts (Rutaceae), and can also be isolated from asymptomatic citrus tissues. Citrus Black Spot occurs in citrus-growing regions with warm summer rainfall cli...
متن کاملAlkylresorcinols in fruit pulp and leaves of Ginkgo biloba L.
These studies were undertaken to characterise resorcinolic lipids (5-n-alk(en)ylresorcinols) composition and to determine their seasonal fluctuations in fruit pulp and leaves of Ginkgo biloba L. Resorcinolic lipid concentrations were consistently higher in fruit pulp than in leaves. In pulp, several mono- and di-unsaturated homologs of alkylresorcinols were the predominant group of analysed lip...
متن کاملPhotosynthetic Decline in Ginkgo Leaves during Natural Senescence
Photosynthetic pigments, biochemical activities and chloroplast ultra-structure were investigated to survey the photosynthetic characteristics of ginkgo (Ginkgo biloba L.) leaves during natural senescence. During leaf senescence, the content of total chlorophyll decreased rapidly while the content of carotenoids changed little; the content of ATP, the activity of O2 evolution of chloroplasts, t...
