A field experiment was established to evaluate quantitative changes in weed species prevailing a crop rotation and 30-year cereal monoculture. The subject of the study included cropping systems: a) rotation, b) First (1989–1992) second (1993–1996) focused on infestation winter triticale monoculture; third (1997–2000) fourth (2001–2004) wheat; fifth (2005–2008), sixth (2009–2012), seventh (2013–...

Seed predation is an important component of seed mortality of weeds in agro-ecosystems, but the agronomic use and management of this natural weed suppression is hampered by a lack of insight in the underlying ecological processes. In this paper, we investigate whether and how spatial and temporal variation in activity-density of granivorous ground beetles (Coleoptera: Carabidae) results in a co...

Leishmaniasis is an important parasitic problem and is in focus for development of new drugs all over the world. Objective of the present study was to evaluate phytochemical, toxicity, and antileishmanial potential of Jurinea dolomiaea, Asparagus gracilis, Sida cordata, and Stellaria media collected from different areas of Pakistan. Dry powder of plants was extracted with crude methanol and fra...

This paper evaluated the frequency, magnitude and dose/concentration range of hormesis in four species: The aquatic plant Lemna minor, the micro-alga Pseudokirchneriella subcapitata and the two terrestrial plants Tripleurospermum inodorum and Stellaria media exposed to nine herbicides and one fungicide and binary mixtures thereof. In total 687 dose-response curves were included in the database....

Abstract Ethanedinitrile is a chemical soil fumigant with promising efficacy against several key pests including weeds, nematodes, and soil-borne pathogens. The of 12 concentrations ethanedinitrile, ranging from 8.7 to 1,751 mg kg − 1 soil, control seeds tubers five weed species ( Cyperus esculentus, C. rotundus, Malva parviflora, Portulaca oleracea , Stellaria media ), two nematode Globodera r...

The expression of many different genes is regulated by ABA and osmotic stress (Skriver and Mundy, 1990). These genes and their products have been characterized in severa1 plants, and they include dehydrins in barley, corn (Close et al., 1989), and Arabidopsis thaliana (Rouse et al., 1992); proteins responsive to ABA (RAB) in rice (Mundy and Chua, 1988; Yamaguchi-Shinozaki et al., 1989); TAS and...

A cDNA clone encoding cytochrome c of Stellaria longipes was isolated and characterized. The nucleotide and predicted amino acid sequences were highly similar to those from other plant, fungal, and animal species. No significant polymorphism was observed among different genotypes (ecotypes). The S. longipes genome contained a low copy number of nucleotide sequences of cytochrome c. The gene exp...
