An Agrobacterium-mediated system for gene transfer in Pinus patula

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

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 ...

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,

Exploring the Volume Paradox: Comparing Different Formulas for Estimating the Wood Volume of Trees and Logs in Nepal. [PDF]

Scientifica (Cairo)
Accurate estimation of tree and log volume plays a pivotal role in a wide range of applications within the field of forestry, especially in biomass assessment and forest management. The effectiveness and applicability of formulas for volume estimation have recently become a topic of extensive deliberation among forestry officials and a diverse array of

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.

Critical Nutrient Concentrations and DRIS Norms for Pinus patula [PDF]

, 2018
Pinus patula is one of the most planted wood conifer species worldwide; however, no foliar nutrient standards exist for this species up to date. The objective of the present study was to generate and verify two sets of foliar nutrient standards for nearly ten-year-old P. patula trees: critical nutrient concentrations and DRIS norms.
