Creeping bentgrass ( Agrostis stolonifera ) is a desirable turfgrass putting green species that susceptible to drought stress. Planting drought-resistant creeping will enhance the resilience of golf turf surfaces, lower required resource inputs, and reduce environmental impact courses. cultivar performance data during stress are needed for informed selection appropriate cultivars. We evaluated ...

Antecedentes y Objetivos: El género Podagrostis incluye 12 especies, incluidas anteriormente en Agrostis hasta hace poco se tenía conocimiento de la existencia tres especies México. La revisión ejemplares herbario reveló presencia una cuarta especie, conocida previamente solo Guatemala. objetivo este trabajo es describir e ilustrar el nuevo registro, discutir identidad del ejemplar examinado la...

BACKGROUND Within the root endosphere, fungi are known to be important for plant nutrition and resistance to stresses. However, description and understanding of the rules governing community assembly in the fungal fraction of the plant microbiome remains scarce. METHODS We used an innovative DNA- and RNA-based analysis of co-extracted nucleic acids to reveal the complexity of the fungal commu...

This study was designed to investigate whether thermotolerant roots exhibit respiratory acclimation to elevated temperatures. Root respiratory acclimation traits in response to increasing temperatures were compared between two Agrostis species contrasting in heat tolerance: thermal A. scabra and heat-sensitive A. stolonifera. Roots of both species were exposed to 17, 27, or 37 degrees C. Root R...

The ecological success of a plant species is typically described by the observed change in plant abundance or cover, but in order to more fully understand the fundamental plant ecological processes, it is necessary to inspect the underlying processes of survival and colonization and how they are affected by environmental conditions. A general ecological hypothesis on the effect of environmental...

Phlebiopsis gigantea (=Phanerochaete gigantea) is a white rot fungus that rapidly colonizes cut stumps, stems, and branches of pine. Two laboratory and several field studies showed that inoculation of red pine logs, Pinus resinosa, with P. gigantea reduced the pitch content of wood, facilitated bark removal, modified wood cells, and controlled detrimental sapstain. Isolations from inoculated lo...

Market-based, supply-side interventions such as domestication, cultivation, and wildlife farming have been proposed as legal substitutes for wild-collected plants and animals in the marketplace. Based on the literature, we devised a list of the conditions under which supply-side interventions may yield positive conservation outcomes. We applied it to the trade of the orchid Rhynchostylis gigant...
