Beek (2016) argued that Rubus aetnicus Cupani ex Weston was the correct name of taxon then called R. canescens DC., and which previously known as tomentosus Borkh. Moreover, stated to be not identical with aetnicus, but rather a form × collinus DC. Matzke-Hajek raised objections both statements. Therefore, aim this study thoroughly analyse names support analysis field work at type localities by...

Studies of biogeographic variation in species abundances are fundamental to understanding and predicting the impacts of invasive exotic species. We quantified the abundance of the introduced and now invasive biocontrol weevil, Rhinocyllus conicus, on a newly adopted native host plant, Cirsium canescens (Platte thistle), across the plant's distributional range. We used regression and structural ...

In the past decade, there has been a growing global interest in antibacterial and antioxidant properties of plants, which are considered safe for use. This study aimed to evaluate ntibacterial activities, as well flavonoid total henolic contents, three wild plant species found Jordan: Rubus canescens DC, Rumex vesicarus L, Urtica pilulifera L. The 70% methanol extracts these plants were tested ...

North Bangkok. ** Department of Chemistry, Faculty of Science, Ramkhamhaeng University. Abstract A new ecdysteroid, P5, has been isolated from the stem bark of aged trees (with flower) of vitex canescens. 20-Hydroxyecdysone, makisterone A, 24-epi-makisterone A, and canescensterone have also been isolated from both young trees (without flower) and aged trees (with flower) of vitex canescens. The...

Little information is available on gene expression profiling of halophyte A. canescens. To elucidate the molecular mechanism for stress tolerance in A. canescens, a full-length complementary DNA library was generated from A. canescens exposed to 400 mM NaCl, and provided 343 high-quality ESTs. In an evaluation of 343 valid EST sequences in the cDNA library, 197 unigenes were assembled, among wh...

Photoluminescence spectroscopic probes offer the potential for differentiation among plant species in real-time. Spectral emission signatures (excitation at 365 nm) from three different pH (2.2, 7.5 and 12.5) phosphate buffered saline (PBS) extracts from two grasses, Sporobolus flexuosus (Thurb. ex Vasey) Rydb., [mesa dropseed], and Pleuraphis mutica Buckley [tobosa], two forbs, Dimorphocarpa w...

Phytoremediation potentials of four poplar lines, Populus nigra (N-SL clone), Populus canescens, and two transgenic P. canescens clones were investigated using in vitro leaf discs cultures. The transgenic poplars overexpressed a bacterial gene encoding gamma-glutamylcysteine synthetase in the cytosol (11ggs) or in the chlopoplasts (6LgI), and therefore, they contained an elevated level of gluta...
