To explore the biosystematics of the Calligonum mongolicum complex (Polygonaceae), the flowering phenological period, breeding and pollination characters and seed set of the complex (Calligonum Mongolicum Turze, Calligonum chinense A. Los., Calligonum gobicum A. Los., Calligonum pumilum A. Los. and Calligonum zaidamense A. Los.) were documented in the Turpan Eremophyte Botanical Garden, China. ...

BACKGROUND Catsper proteins are responsible for entering Ca(2+) to the cell and play an important role in sperm motility and male fertility. Antioxidants are vital for sperm motility too. Escanbil (Calligonum) extract possess some of the important antioxidant like Catechin and Quercetin. OBJECTIVE Here we investigated the effects of Escanbil (Calligonum) extract on the sperm parameters and th...

Five Calligonum species endemic to the Tarim Basin - C. roborowskii, C. kuerlese, C. juoqiangense,C. yengisaricum, and C. taklimakanense - were compared using 14 morphological characteristics and nrDNA ITS and cpDNA trnL-F molecular data. Intraspecific and interspecific morphological variation was uncovered, with variation between species significant for most characteristics. Based on Euclidean...

objective: antioxidants are essential for sperm motility. calligonum extract possesses the important antioxidants catechin and quercetin. this study investigates the effects of calligonum extract on sperm parameters and the rate of apoptosis in testes of aging male mice. methods: we initially performed a dose response test with using three doses of calligonum (10 mg/kg, 30 mg/kg and 50 mg/kg). ...

this study represents phylogenetic analyses of two woody polygonaceous genera calligonum and pteropyrum using both chloroplast fragment (trnl-f) and the nuclear ribosomal internal transcribed spacer (nrdna its) sequence data. all inferred phylogenies using parsimony and bayesian methods showed that calligonum and pteropyrum are both monophyletic and closely related taxa. they have no affinity w...

Calligonum comosum (Polygonaceae), an Egyptian desert plant, was extracted and fractionated using petroleum ether, methylene chloride, and ethyl acetate. The total methanolic extract and other fractions were tested for their anticancer activity using Ehrlich ascites, brine shrimp and antioxidant assays. Ethyl acetate fraction proved to be the most active in all assays. Eight compounds were isol...

Since phylogenetic data provide the evolutionary history of the species and traits are the result of adaptation to the environmental conditions, joint analysis of these two aspects and ecological data may illuminate that how ecological processes affect the evolution of species and assembly of communities. In this study, we compared the community structure of sibling communities in order to illu...
