Distributions and Conservation Status of Carrot Wild Relatives in Tunisia: A Case Study in the Western Mediterranean Basin

Crop wild relatives, the wild progenitors and closely related cousins of cultivated plant
species, are sources of valuable genetic resources for crop improvement. Persisting gaps
in knowledge of taxonomy, distributions, and...

Using DNA barcoding to improve invasive pest identification at U.S. ports-of-entry

Interception of potential invasive species at ports-of-entry is essential for effective biosecurity
and biosurveillance programs. However, taxonomic assessment of the immature stages
of most arthropods is challenging; characters for...

Seeds and the Art of Genome Maintenance

Successful germination represents a crucial developmental transition in the plant
lifecycle and is important both for crop yields and plant survival in natural ecosystems.
However, germination potential decreases during storage and seed...

The Development of Plant Conservation in Botanic Gardens and the Current and Future Role of Conservation Genetics for Enhancing Those Conservation Efforts

Botanic gardens play major roles in plant conservation globally. Since the 1980s, the number of botanic gardens worldwide and their involvement in integrating ex situ and in situ plant conservation has increased signifi cantly, with a growing focus on...

Training in Plant Genetic Resources Management: A Way Forward

The USDA-ARS National Plant Germplasm System (NPGS) is a coordinated network of 19 genebank locations throughout the United States that perform research to acquire, maintain,
regenerate, document, distribute, characterize, and evaluate plant...

Using herbaria to study global environmental change

During the last centuries, humans have transformed global ecosystems. With their temporal
dimension,herbaria provide the otherwise scarce long-termdata crucial for trackingecological and
evolutionarychangesover thisperiodof intense global...

The history and impact of digitization and digital data mobilization on biodiversity research

The first two decades of the twenty-first century have seen a rapid rise in the mobilization of digital biodiversity data. This has thrust natural history museums into the forefront of biodiversity research, underscoring their central role in the...

Botanic gardens are an untapped resource for studying the functional ecology of tropical plants

Functional traits are increasingly used to understand the ecology of plants and to predict their responses to global changes. Unfortunately, trait data are unavailable for the majority of plant species. The lack of trait data is especially prevalent...

Comparative Biology of Cycad Pollen, Seed and Tissue - A Plant Conservation Perspective

Cycads are the most endangered of plant groups based on IUCN Red List assessments; all are in Appendix I or II of CITES, about 40% are within biodiversity ‘hotspots,’ and the call for action to improve their protection is longstanding. We contend that...

2018 State of the World's Fungi

The facts and figures contained in the pages of this report and accompanying website will probably come as a total revelation to many people. The first of its kind outlining the state of the world’s fungi, the report highlights just how important fungi...

Tree Genes Initiative REPORT 2018: Securing our Future Forests by Enhancing Technology, Capacity, and Speed

The first TGI report, published in 2015, identified eight critical gaps slowing the transfer of stress-adapted trees from upstream research to forest owners and managers. The gaps fell into three categories: Innovation, Policy, and Markets. TGI members...

Priority Actions to Improve Provenance Decision-Making

Selecting the geographic origin—the provenance—of seed is a key decision in restoration. The last decade has seen a vigorous debate on whether to use local or nonlocal seed. The use of local seed has been the preferred approach because it is expected...

For Endangered Florida Tree, How Far to Go to Save a Species?

The Florida torreya is North America’s most endangered conifer, with less than one percent of its population remaining. Now, scientists are mounting a last-ditch effort to save the torreya and are considering using new gene-editing technologies to...

National Seed Strategy for Rehabilitation and Restoration

The PCA Federal Committee, chaired by the Bureau of Land Management, developed the “National Seed Strategy for Rehabilitation and Restoration 2015-2020” in cooperation with Federal and non-Federal partners. The “National Seed Strategy for...

A Workflow to Preserve Genome-Quality Tissue Samples From Plants in Botanical Gardens and Arboreta

Internationally, gardens hold diverse living collections that can be preserved for genomic research. Workflows have been developed for genomic tissue sampling in other taxa (e.g., vertebrates), but are inadequate for plants. We outline a workflow for...

State of the World's Plants 2017

Last year's State of the World’s Plants report focused predominantly on synthesising knowledge of the numbers of different categories of plants: How many vascular plants are currently known to science? How many are threatened with extinction? What is...
