Commodity risk assessment of Malus sylvestris plants from United Kingdom

EFSA Journal, Volume 21, Issue 6, June 2023., 2023
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers plant health risks posed by rooted plants and bundles of bare root plants or

Bursting Phenomenon and Chaos Phase Control in Plant Dynamics

Complexity, Volume 2023, Issue 1, 2023., 2023
New complex features of a Pinus family plant subjected to wind load by proposing an analog electronic simulator with an active RC realization that mimics the real‐time dynamics of the system was examined in this paper. Findings reveal that the periodic or chaotic dynamics of the system depends on the favored initial conditions.

BIOCHEMICAL COMPOSITION OF VEGETATIVE EXPLANTS AND CALLUS PINUS SIBIRICA DU TOUR

chemistry of plant raw material, 2020
The methods of sterilization of annual shoots Pinus sibirica Du Tour and the conditions for their introduction into in vitro culture were studied. Induction of callusogenesis of aseptically viable explants of P. sibirica proceeds more intensively on the modified Murasige-Skoog medium: hormonal supply of 0.4% kinetin and 0.25% 6-benzylaminopurine ...

Teasing apart the joint effect of demography and natural selection in the birth of a contact zone

New Phytologist, Volume 236, Issue 5, Page 1976-1987, December 2022., 2022
Summary Vast population movements induced by recurrent climatic cycles have shaped the genetic structure of plant species. During glacial periods species were confined to low‐latitude refugia from which they recolonized higher latitudes as the climate improved.

Climate drove the fire cycle and humans influenced fire occurrence in the East European boreal forest

Ecological Monographs, Volume 92, Issue 4, November 2022., 2022
Abstract Understanding long‐term forest fire histories of boreal landscapes is instrumental for parameterizing climate–fire interactions and the role of humans affecting natural fire regimes. The eastern sections of the European boreal zone currently lack a network of annually resolved and centuries‐long forest fire histories. To fill in this knowledge

Environmental factors have a major effect in shaping the gene expression of Siberian larch in the Altai Mountains of China

The Plant Genome, Volume 15, Issue 3, September 2022., 2022
Abstract The differentiation of gene expression is an important link between genotype and phenotype and has important contributions to species adaptation and ecosystem evolution. As a major component of the world's forests, boreal forests play an important role in regulating the global climate, and the phenology of tree species has been and is ...
