Sedum peltatum M.L. Chen et X.H. Cao, belonging to the family Crassulaceae DC., is described and illustrated from China as a new species. It was collected from Nanwu canyon, Huangnikeng valley, Gaokeng valley and Qingshikeng valley in the Jiulong Mountains, China (P. R.). Morphological diagnostic characters of closely related species are also discussed. Introduction Sedum L. is the largest and ...

Macrophytes play important roles in shallow aquatic ecosystems. Stable isotope signatures of macrophytes indicate the environmental conditions and macrophyte contributions to food webs. However, have been studied less than other organisms. We determined stable C N 10 plant species from Poyang Lake wetland (Wucheng, Yongxiu County) Nanji (Nanjishan, Xinjian Jiangxi Province, which are Chinese na...

The pollen morphology of Pelargonium endlicherianum Fenzl. and Pelargonium quercetorum Agnew. from the family Geraniaceae was examined under light microscopy and scanning electron microscopy. Pollen morphologies are eurypalynous. The pollen grains were tricolporate, prolate-spheroidal and large. Aperture was ectoaperture, colpus was short, and the pores were oblate-spheroidal and large. The exi...

The hypoglycaemic activities of four water ethanol extracts (WEE) prepared from Bidens pilosa L., Salvia officinalis L., Psacalium peltatum H.B.K. (Cass) and Turnera diffusa Willd. were investigated in healthy and alloxan-diabetic mice. The WEE of S. officinalis significantly reduced the blood glucose of fasting normal mice 120 (15.7%) and 240 min (30.2%) after intraperitoneal administration (p...

This is the second article published in the Trees for Life Journal which deals with radioprotection (see http://www. tfljournal.org/article.php/2007042416194363 by Sancheti and Goyal). While it is not a major focus of this journal, radioprotection has interest for our readership and is attracting ever more attention within the scientific community. No synthetic radioprotective chemicals are ava...

The antifungal effect of 10 plant extracts viz., Thevetia peruviana, Ocimum basilicum, Piper betel, Murraya koenigii, Chrysanthemum coronarium, Polyalthia longifolia, Catharanthus roseus, Pelargonium graveolens, Moringa officinalis and Lawsonia inermis were evaluated by poisoned food technique against Rhizoctonia solani Kuhn, the causal organism of sore shin disease of tobacco. Among all the pl...

Phytoremediation is a set of technologies that uses plants to clean up contaminated soils and groundwater. Phytoremediation is environmentally friendly, successful and cost-effective compared to other in situ methods such as the electrokinetic method. In this work, two local plant species, Chrysanthemum and Pelargonium, were examined for their ability to uptake lead from lead contaminated soils...

Pelargonium zonate spot virus (PZSV) is identified recently in tomato plants in the United States. To develop serological diagnostic tools for the detection of this virus, the production of good quality antibodies is a necessity. The coat protein (CP) gene of a California isolate of PZSV was cloned into a bacterial expression vector (pTriEX-4 Ek/LIC). The plasmid pTriEX-4-PZSV-CP was transforme...
