An Agrobacterium-mediated system for gene transfer in Pinus patula [PDF]

South African Journal of Botany, 2008
AbstractA pioneer study investigating the feasibility of using Agrobacterium-mediated gene transfer was undertaken in Pinus patula, the most important softwood species in South African forestry. This was achieved via the introduction of pAHC25 under the control of the ubiquitin promoter. A variety of target tissues were tested including: mature zygotic

Artificial seed from Pinus patula somatic embryos [PDF]

South African Journal of Botany, 2002
Somatic and zygotic embryos of Pinus patula Scheide et Deppe. were encapsulated in 2.2% sodium alginate to examine the potential of producing artificial seeds. The alginate beads were supplemented with sucrose, maltose and activated charcoal. Somatic embryos encapsulated in alginate beads supplemented with both sucrose and charcoal germinated from the ...

Panel statement on young pine plants used for afforestation or reforestation as pathway for pinewood nematode (PWN) <i>Bursaphelenchus xylophilus</i>. [PDF]

EFSA J
Abstract Pinewood nematode (PWN) (Bursaphelenchus xylophilus) is a destructive pest of Pinus trees worldwide which depends for transmission on the cerambycid insects of the genus Monochamus. EFSA was asked to assess the potential role of young host plants for afforestation or reforestation planting as a pathway for PWN. According to legislation (EU COM/

Global population structures and demographic history of Suillus luteus, a pine co-introduced ectomycorrhizal fungus associated with exotic forestry and invasion. [PDF]

New Phytol
Global phylogenomic tree and phylogenetic network of Suillus luteus and its closely related species. Summary Human colonization since the 19th century has resulted in the global spread of pines beyond their original northern boreal distribution. Although the introduction history of pines is documented through historical records, little is known about ...

Equipped for success: genomes and metabolomes of the European Amanita muscaria are conserved in its novel South African range. [PDF]

New Phytol
Summary Plants and soils have been moved around the world for centuries, but invasive mushrooms receive scant attention. The Amanita muscaria species complex was introduced to South Africa in the context of forestry, but its origins, ecology and recent evolution are unstudied. We sequenced the genomes of 24 Northern and Southern Hemisphere A. muscaria,

Do Giant Sequoias Regenerate in Large Crown Fire Patches? [PDF]

Ecol Evol
While it is widely recognized that giant sequoias are serotinous and reproduction is positively associated with high‐severity fire, land managers hypothesize that giant sequoias cannot effectively reproduce in large crown fire patches. We investigated this issue in two large high‐severity fire patches, dominated primarily by crown fire, in Redwood ...

Ecological and Social Dimensions of Human-Bear Coexistence in Nepal's Gaurishankar Conservation Area. [PDF]

Ecol Evol
We modelled habitat suitability for Asiatic black bears in Nepal's Gaurishankar Conservation Area and combined it with community surveys to understand human–bear coexistence. Our results show that bear habitat is concentrated between 1000 and 3000 m and that conflict is rising in forest‐edge communities.
