Up and down: stamen movements in Ruta graveolens (Rutaceae) enhance both outcrossing and delayed selfing.
BACKGROUND AND AIMS Stamen movements directly determine pollen fates and mating patterns by altering positions of female and male organs. However, the implications of such movements in terms of pollination are not well understood. Recently, complex patterns of stamen movements have been identified in Loasaceae, Parnassiaceae, Rutaceae and Tropaeolaceae. In this study the stamen movements in Rut...
متن کاملMolecular authentication of the medicinal herb Ruta graveolens (Rutaceae) and an adulterant using nuclear and chloroplast DNA markers.
Dried parts of different plant species often look alike, especially in powdered form, making them very difficult to identify. Ruta graveolens, sold as a dried medicinal herb, can be adulterated with Euphorbia dracunculoides. The genomic DNA was isolated from the leaf powder (100 mg each) using the modified CTAB method. Internal transcribed spacer sequences of nuclear ribosomal DNA (nrDNA-I...
متن کاملAnti-tumour activity of Ruta graveolens extract.
An extract of Ruta graveolens was found to be cytotoxic to Dalton's lymphoma ascites (DLA), Ehrlich ascites carcinoma (EAC) and L929 cells in culture (IC100=16 mg/ml) and also to increase the lifespan of tumour bearing animals. The extract further decreased solid tumours developing from DLA and EAC cells when given simultaneously with elongation of the lifespan of tumour-bearing animals. A home...
متن کاملSpeed Up, Slow Down or Both? Investigating the Contemporary Cities
Speed as a crucial phenomenon of modernism affects individual and collective life of human being and changes the traits of the places people live in. Increasing speed is the demand of the modern era, though on the other side in recent years there is a contrary incline towards slowing down different aspects of life. In view of this, the dualities in between social features of Speed up and slow d...
متن کاملEvolution of Mating Systems: Outcrossing versus Selfing
Mating systems vary enormously among groups of organisms. This has led to diverse definitions and approaches for investigating their evolution and maintenance. Animal mating systems are characterized by different patterns of parental investment in offspring and variation in the extent to which sexual selection shapes male and female traits (see chapter VII.4). A primary focus of most studies is...
