SHOOT REGENERATION FROM LEAF TISSUES OF AMERICAN ELM AND SIBERIAN ELM.

Elm trees and elm leaf beetles: patterns of herbivory

ELM physics and ELM mitigation in ITER

Edge Localised Modes are characteristic of the high performance, H-mode plasmas that are required for the attainment of Q = 10/500MW fusion power in the first phase of ITER operation. The energy released by a type I ELM, in good confinement plasmas, is typically 510% of the plasma stored energy; with low collisionality plasmas at the upper end of the range. Dimensional analysis, experiment and ...

Simultaneous induction of jasmonic acid and disease-responsive genes signifies tolerance of American elm to Dutch elm disease.

Dutch elm disease (DED), caused by three fungal species in the genus Ophiostoma, is the most devastating disease of both native European and North American elm trees. Although many tolerant cultivars have been identified and released, the tolerance mechanisms are not well understood and true resistance has not yet been achieved. Here we show that the expression of disease-responsive genes in re...

New elm hopes

those of Brazil and Congo, and their biological diversity is unique. But logging is putting the forest ecosystems under unprecedented pressure — between 1990 and 2005, Indonesia lost 28 million hectares of forest, most of it virgin forest. The government has banned the export of unprocessed logs from the country but timber is regularly smuggled out via Malaysia and Singapore for processing in o...

Isolation and characterization of microsatellite markers for red elm (Ulmus rubra Muhl.) and cross-species amplification with Siberian elm (Ulmus pumila L.).

Ulmus pumila is an elm species, non-native to the USA that hybridizes with Ulmus rubra. In order to study the genetic structure and hybridization patterns between these two elm species, we developed 15 primer pairs for microsatellite loci in U. rubra and tested their cross-amplification in U. pumila. All 15 primers amplified in both species, 11 of which possessed species-specific alleles. Eight...
