Heterostyly (i.e., reciprocal placement of anthers and stigmas between two or three floral morphs) is hypothesized to enhance outcrossing and reduce selfing. However, few studies have documented reciprocity among individual plants; instead, mean anther and stigma heights for floral morphs are usually reported, masking interindividual variation. We measured eight floral dimensions for individual...

Microclimatic conditions of tropical forest favour the high richness of bryophytes, which by being sensitive to environmental changes, are important indicators of habitat conditions. The aim of this study was to determine the richness and species composition of the bryophyte flora in fragments of terra firme forest on the great curve of the Xingu River, Pará state, Brazil. The collections were ...

Salinity is a major abiotic stress that affects plant growth and productivity. To cope with salt stress, plants express large number of responsive genes proteins are involved in wide range cellular functions. In the present study, halophytic Suaeda maritima (L.) Dumort. were hydroponically exposed to NaCl for understanding molecular mechanisms behind salinity tolerance using PCR-based Suppressi...

The accumulation of heavy metals in naturally occurring plants of herbs, shrubs and trees grown on South Bolanda coal mine overburdens in subtropical region of India were illustrated.. The inter-elemental relationships of different parts of five plant species including herbs, shrubs and trees with the coal mine wastes were studied. From the tree species maximum positive correlation was observed...
