2.09.02 - Somatic embryogenesis and other vegetative propagation technologies



6th IUFRO 2.09.02 Conference

The might of vegetative propagation for healthy and productive forests to face climate challenges
Rotorua, New Zealand; 3-8 March 2024

In the context of rapid climate change, there is an urgent need for cost-effective, efficient tree vegetative propagation (bio)technologies for supporting the development of precision forestry and delivery of forest products and services. Innovative technologies could be of importance for both deployment of adapted, healthy, commercial varieties in planted forests and preservation of natural forest areas, thus to the integrated benefit of the industry and society. In New Zealand there is a marked societal dimension in forestry through the historical strong and practical involvement of Te Ao Māori.

The programme sessions proposed will cover all fields of application of vegetative propagation to preserve, assess, improve, adapt, and deploy tree genetic resources in resilient and productive forests. We will encourage any submission on vegetative propagation of trees as a primary strategy and/ or in synergy with seed technologies to cope with climate change. Oral and poster presentations should be in line with the urgent need worldwide for large numbers of seed and plant resources from species and varieties adapted to the anticipated new conditions.

About Unit

The main objective of this Unit on "Somatic Embryogenesis of Forest Trees" is to foster the development and application of somatic embryogenesis (SE) technology in both coniferous and hardwood tree species. Research areas of this unit include: the development and refinement of the SE system for commercially and ecologically important tree species; the application of SE in tree breeding and vegetative deployment in multi-varietal forestry balancing genetic gain and diversity; the use of SE in genetic resource conservation, biotechnology, genomics, molecular biology, and insect and disease resistance; and the study of related disciplines such as cryopreservation and using molecular makers for examining genetic stability and integrity of SE produced plants.

State of Knowledge

Since its first success in conifers (Hakman et al 1985; Chalupa 1985; Nagamani and Bonga 1985), SE has been achieved for many tree species. Important advances have also been made in SE of angiosperm species (Merkle and Nairn 2005) in recent years. Somatic embryogenesis is the primary enabling technology for most tree biotechnology products and offers new opportunities for tree breeding, vegetative deployment, and genetic resource conservation and restoration. It also provides indispensable tools for R&D in biotechnology, genomics and molecular biology. However, an important current application of SE, in conjunction with cryopreservation, is its integration into tree breeding and deployment programs where plants derived from SE are routinely produced. Furthermore, in various parts of the world, SE is commercially implemented in high-value multi-varietal forestry, especially for some Picea and Pinus species. Despite the important advantages it offers, SE is often difficult to obtain or is obtained at a very low frequency for some commercially and ecologically important tree species thus requiring further research and development.
