Plant tolerance of heat stress involves various changes at physiological and molecular levels. The objective of this study was to examine the expression of a gene encoding expansin protein in relation to heat tolerance in two C(3) grass species and genotypes differing in heat tolerance. Heat-tolerant, thermal Agrostis scabra, adapted to high temperatures in geothermal areas in Yellowstone Natio...
Agrostopoa Davidse, Soreng & P. M. Peterson, a new genus endemic to the páramos of Colombia, is proposed. The genus includes two new species, A. barclayae Davidse, Soreng & P. M. Peterson and A. woodii Soreng, P. M. Peterson & Davidse, and a third species transferred from Muhlenbergia Schreber, A. wallisii (Mez) P. M. Peterson, Soreng & Davidse (lectotype designated here). A key for determining...
BACKGROUND AND AIMS To improve the management of grass communities, early plant development was compared in three species with contrasting growth forms, a caespitose (Lolium perenne), a rhizomatous (Poa pratensis) and a caespitose-stoloniferous species (Agrostis stolonifera). METHODS Isolated seedlings were grown in a glasshouse without trophic constraints for 37 d (761 degrees Cd). The appea...
