It is really hard to believe that 2014 is almost at an end! Looking back over the year, we have ‘planted some small seeds’ that we hope will flourish into the future. We have made contact with some new members to the group and managed to get this blog started (although we did not publish as many posts as we would have liked to… it is a start). Even more exciting, is that we have also been in discussions around hosting a small conference next year, and plans to do so are underway – so look out for more information on that early in January 2015!!! We are really looking forward to it!
Wishing you all the very best over the Festive Season, and for the New Year ahead!
Introduction to our ‘Guest Blog’ below (by Shelagh McCartan)
During September, I was able to attend a very well-organised conference in Vitoria-Gasteiz, Spain (IUFRO Working Party 2.09.02 – Somatic Embryogenesis and Other Vegetative Propagation Technologies). For more information on the conference click here. I learned a great deal, particularly around the problems regarding ‘maturation of embryos’ and ‘conversion to plantlets’, and I believe that there is scope for input from seed scientists. I was particularly fascinated by the presentation by Jeff Hartle and his colleagues from Weyerhaeuser on ‘manufactured seeds’, and requested Jeff to send us some more information on this interesting topic.
Guest Blog by Jeff Hartle (MSeed Development Scientist, Weyerhaeuser Co.)
Modern agriculture often requires the planting of large numbers of genetically identical plants that have been selected to have advantageous properties. Production of new plants by sexual reproduction, which yields botanic seeds, is usually not feasible. Asexual propagation, via several pathways has been used for many years to produce large numbers of genetically identical individuals. In many species these are called varieties. One method to produce varieties is to use somatic embryogenesis. At Weyerhaeuser, we have developed machinery, protocols and logistics for the large-scale automated production of conifer somatic embryos. We have also developed a synthetic seed technology we call ‘manufactured seed’ that are made on an automated assembly line. This system allows large quantities of manufactured seed to be produced with minimal labor. As compared to most clonal techniques, the use of somatic embryos with manufactured seed allows steady-state manufacturing. As manufactured seed are created, they can be stored allowing a large quantity to be produced over time. When conditions are right for planting, the manufactured seed can be pulled from storage and planted en-masse. Manufactured seed also allows for centralized manufacturing with shipping to various facilities for planting. We have tested manufactured seed with several conifer species, but also found good performance with dissected corn, wheat and soybean embryos. For further information, click here.
In 2010, I was very privileged to attend the IUFRO World Congress in Seoul, Korea. It was my first opportunity to attend such an enormous conference, with over 2500 delegates from around 90 countries – and what a fantastic experience it was! This year, a few of my South African colleagues have travelled across the Atlantic Ocean to attend the IUFRO 2014 World Congress in Salt Lake City, USA, and I am sure it will be another outstanding event (you can follow the current updates on the Congress here)! We would love to get some feedback on the Congress to put on this blog, so if you, or a colleague, have been fortunate enough to attend the IUFRO World Congress this year, then we’d love to hear from you!
You may be wondering… what events are happening in the world of ‘seed science’ in the near future?
Well, we are very excited about the upcoming International Society for Seed Science (ISSS) Seed Longevity Workshop which will be held in Wernigerode, Germany, from 5-8 July 2015. This promises to be a very interesting workshop with a great selection of keynote speakers that have been confirmed. The topic of the conference is “Seeds for future generations – Determinants of longevity”. For more information, click here.
And… we are also in the process of planning a small conference for 2015… so, ‘watch this space’ for more information!
The ISSS conference in China is less than three weeks away! Are you registered? If not, when last did you attend a seed science conference? Which factors do you consider critical when signing up for a conference?
Please take our short poll above so that we can get some feedback from you on whether there is sufficient demand and interest for a seed science conference early to mid 2015.
Marnie at a Pinus patula pot trial set up to investigate a nursery pathogen.
Dr Marnie Light (Working group deputy coordinator)
Programme Manager / Scientist at the Institute for Commercial Forestry Research, South Africa
What do I do?
Manage a small team of researchers and technicians to conduct research related to silvicultural management of commercial pine or eucalyptus plantations in South Africa. This programme covers research on:
Pine and eucalypt regeneration
Eucalypt coppice management
Integrated pest management
Communicate research findings and practical applications to our stakeholders and relevant private growers.
Publish relevant reports and peer-reviewed papers.
Assist and mentor students.
Through an honorary appointment at the University of KwaZulu-Natal, I conduct some research related to smoke-stimulated seed germination.

Shelagh collecting juniper berries on the slopes of Hellvelyn (3rd highest mountain in England).
Dr Shelagh McCartan (Working group coordinator)
Seed Scientist at Forest Research, Forestry Commission, Britain
What do I do?
Co-ordinate and deliver a programme of seed biology research, which focuses on:
processing, pre-treating, and storing seeds of important forestry species (Douglas fir, Scots pine and Common ash) and also novel forestry species (Atlantic cedar, Coast redwood and European silver fir); and
developing thermal time models and predicting benefits and risks associated with assisted migration of forestry species as part of a climate change adaptation strategy.
Co-ordinate a UK-wide collection of juniper berries for the UK National Trees Seed Project as part of an ex situ conservation effort.
Communicate research to public, practitioners and professionals through appropriate media including workshops, technical articles, and peer-reviewed papers.
Mentor and train students.

This blog replaces the electronic newsletter. It is your forum for posting newsworthy items including information about conferences, workshops and jobs etc. Please send the items to us and we will upload them as soon as possible. We also hope to include opinion pieces on topics by invited researchers. In the meantime, please bear with us as we are amateur web-masters!
…a discussion forum for seed scientists world-wide.
