Continued reduction in limited natural resources worldwide increasingly necessitates the incorporation of low-maintenance and low-input plant materials into urban landscapes. Some fine-leaved Festuca grass species have been used in formal gardens and native urban landscapes because of their inherent tolerance to abiotic stresses, but native, ornamental types (tall and non-spreading with multico...

Asafoetida (Ferula assa-foetida L.) is one of the endemic medicinal plants in Iran. Analysis karyomorphology and 2Cx DNA measurements (monoploid genome size) 18 Iranian Ferula populations were performed. The vitro embryo-derived root tips examined for karyological studies, via technique squash stain with 2% (w/v) aceto-orcein. Seeds samples leaves Solanum lycopersicum as standard reference (2C ...

The chloroform extract of Ferula persica var. persica roots was found to inhibit red pigment production of Serratia marcescens. A bioguided fractionation study by preparative thin layer chromatography (PTLC) detected a fraction (Rf = 0.71, petroleum ether/EtOAc, 2:1 v/v), which was effective on depigmentation of Serratia marcescens. Using conventional spectroscopy methods, the active fraction w...

BACKGROUND Phosphoglucose isomerase (PGI, EC 5.3.1.9) is an essential metabolic enzyme in all eukaryotes. An earlier study of the PgiC1 gene, which encodes cytosolic PGI in the grass Festuca ovina L., revealed a marked difference in the levels of nucleotide polymorphism between the 5' and 3' portions of the gene. METHODS In the present study, we characterized the sequence polymorphism in F. o...
