A tree of life for more than 9500 plant species

Australian timber industry news - Mon, 06/05/2024 - 03:19
An international team of researchers, including scientists from CSIRO, Australia’s national science agency, have produced a genomic ‘tree of life’ using the DNA sequences of more than 9,500 flowering plant species. The tree of life presents the most up-to-date understanding of flowering plants which will help scientists do everything from plant classification to discovery of new medicines. Source: Timberbiz The tree of life was built using 1.8 billion letters of genetic code sequenced from living plants and centuries-old specimens held in herbaria across Australia and the world. It includes extinct and endangered species and contains 15 times more data than any comparable studies of the flowering plant tree of life, as well as 800 plants that have never had their DNA sequenced before. The tree of life presents the most up-to-date understanding of flowering plants which will help scientists do everything from plant classification to discovery of new medicines. It is also a step toward building a tree of life for all 330,000 known species of flowering plants by Royal Botanic Gardens, Kew’s Tree of Life Initiative. The paper ‘Phylogenomics and the rise of the angiosperms’ was published in the journal Nature by an international team of 279 scientists from 138 organisations internationally, led by the Royal Botanic Gardens, Kew. CSIRO contributed to this collaborative effort through the Genomics for Australian Plants (GAP) Framework Initiative consortium led by Bioplatforms Australia and partner organisations. “The Genomics for Australian Plants consortium contributed DNA sequences of 774 Australian plant species. CSIRO, a major partner in the GAP consortium, contributed daisies and orchids from CSIRO’s National Research Collections Australia. “The flowering plant tree of life maps how the flowering plants are related to each other. This important tool will have many uses from discovering new medicines, to biological control of invasive species,” CSIRO Research Scientist Dr Alexander Schmidt-Lebuhn said. “This is because closely related species tend to have similar pharmaceutical properties and may be vulnerable to the same biocontrol agents. What we know about one species can guide how we study, use and manage its relatives. CSIRO Research Scientist Dr Katharina Nargar, explained that the National Research Collections Australia at CSIRO hold 15 million specimens of plants, insects, fish and more. “Our collections are hugely valuable in large-scale, international studies of biodiversity. They provide critical data on the many species which are only found in Australia, like the sexually deceptive hammer orchids, which trick male thynnid wasps to pollinate them by resembling female thynnid wasps,” she said. “The flowering plant tree of life will help unravel the mystery of how flowering plants evolved. For example, it will help us understand how our highly unique Australian flora was assembled and evolved over time. “The Australian continent has a long history of isolation from other landmasses and underwent drastic climatic changes over geological time. Of over 21,000 Australian plant species, more than 80% occur nowhere else on the planet. Where did they come from? How did a changing climate impact their evolutionary trajectory?”

Huge 3D printer to help build more houses

Surpassing its own 2019 Guinness World Record for the largest polymer 3D printer, the University of Maine in the US unveiled a next-generation printer that is four times larger than its predecessor to catalyse the future of sustainable manufacturing in a number of industries. Source: Timberbiz The new printer, dubbed Factory of the Future 1.0 (FoF 1.0), was unveiled at the Advanced Structures and Composites Centre (ASCC). The thermoplastic polymer printer is designed to print objects as large as 96 feet long by 32 feet wide by 18 feet high, and can print up to 500 pounds per hour. It offers new opportunities for eco-friendly and cost-effective manufacturing for numerous industries, including affordable housing, bridge construction, ocean and wind energy technologies and maritime vessel fabrication. The design and fabrication of this world-first printer and hybrid manufacturing system was made possible with support from the Office of the Secretary of Defense through the US Army Corps of Engineers. FoF 1.0 isn’t merely a large-scale printer; it dynamically switches between various processes such as large-scale additive manufacturing, subtractive manufacturing, continuous tape layup and robotic arm operations. Access to it and MasterPrint, the ASCC’s first world-record-breaking 3D printer, will streamline manufacturing innovation research at the centre. The two large printers can collaborate by sharing the same end-effectors or by working on the same part. The one-of-a-kind printer will advance various initiatives, including the development of biobased feedstocks from wood residuals abundant in Maine. This technology will advance commercialization efforts such as BioHome3D and the creation of sustainable, affordable housing. The FoF 1.0 unveiling comes ahead of a planned ground-breaking new 47,000-square-foot research laboratory called the Green Engineering and Materials (GEM) Factory of the Future. Scheduled for an August, the facility is positioned to enhance manufacturing innovation across multiple sectors. Its primary aim is to facilitate and scale up more sustainable manufacturing practices by introducing next-generation solutions and biomaterials, addressing challenges such as a diminishing workforce and strained supply chains with local solutions. “Maine needs an estimated 80,000 additional homes by 2030, many specifically for households with incomes at or below the area median income. This new technology allows UMaine-ASCC to scale-up its research and production of its innovative biobased 3D printed home technology,” said Maine Housing’s Development Director Mark Wiesendanger. “This effort creates another means of producing quality affordable housing, while further driving costs down, and using abundant wood residuals from Maine’s sawmills. We look forward to continuing our collaboration with Dr Dagher, the staff and students at UMaine/ASCC in demonstrating how 3D printed homes and other next-generation housing technologies will quickly and effi iently contribute to enhancing Maine’s housing stock.” The research facility will not only scale up advanced manufacturing processes, but also explore innovative materials systems by prioritizing recycled and biobased materials. Maine, the most forested state in the nation, annually produces more than one million tons of wood residuals in its sawmills, which can be used as feedstock for 3D printing. In addition, UMaine, with the GEM initiative, has prioritized manufacturing workforce development by offering experiential learning and entrepreneurial training programs aimed at nurturing the next generation of leaders.
