Poplars and pines have been plant flagship agro-forestry crops for bioenergy production, resulting in large amount of resources being devoted to its production and improvement. One of the most important threats to the sustainable growth of trees in plantation is attack by pathogens. Two important aspects in preventing outbreaks are early detection, monitoring and surveillance….
Early Diverging Lineages of Fungi
Fungi inhabit most of the world’s ecological niches where they perform numerous services that are central to ecosystem functioning. Despite significant advancements in our understanding of the evolutionary relationships within Kingdom Fungi, the earliest diverging events are still very poorly understood. Resolving the earliest branches in the Kingdom Fungi is essential to identify the characteristics…
Snow Algae Comparative Genomics
Temperature is one of the most important abiotic determinants of the vitality, viability and distribution of life forms and therefore the biology of cold-adapted organisms is of broad general interest. As polar temperatures rise, the permanent frozen portion of the Arctic is shrinking, as is the geographical region with a summer average of 10ºC, which…
How Ascomycetes Degrade Plant Biomass
Aspergilli are generalist species that are able to consume a broad range of substrates. In contrast, species such as P. anserina are much narrower in their substrate utilization profile, which correlates with its biotope on herbivore dung. The soil fungus T. reesei is an intermediate species, which has a broader biotope range than P. anserina,…
Modeling Brachypodium-Trichoderma symbiosis
Secondary metabolites are a heterogeneous group of natural compounds that are considered to aid the producing organism in survival and basic functions. Trichoderma spp. are known to produce over 200 secondary metabolites, of which many have been found to have biological activity on plants, microbes and substrates. Among these metabolites, polyketides have important biological activities…
Intermediate Wheatgrass Project
Intermediate Wheatgrass (IWG) is a highly productive perennial grass species that is being developed as a new biomass and grain crop. As a perennial crop, IWG can provide essential ecosystem services to current agricultural practices such as stabilizing soil with its deep root structure, reducing nutrient runoff, and limiting weed growth. IWG produces biomass quantities…
Fungal Evolution of Truffle-Like Bodies
The reproductive success of fungi is heavily influenced by climate. For those fungi that produce emergent mushroom-like fruit bodies, periods of drought or heat can severely curtail the spread of these fungi within an ecosystem due to rapid drying of the developing hymenium thus limiting spore production and dispersal. Some fungi have evolved the adaptation…
Diurnal Cycles in Chlamydomonas
Chlamydomonas reinhardtii is a DOE JGI flagship species and the premier reference organism for unicellular green algae. It is an important reference system for many aspects of plant cell and molecular biology, especially as they relate to energy and carbon metabolism including lipid and starch storage and utilization in photosynthetic systems. Chlamydomonas offers an unprecedented…
JGI at PAG XXIV
JGI will be sharing a booth (#202) at The Plant and Animal Genome XXIV Conference (PAG) in San Diego from Sunday, January 10 through Tuesday, January 12, 2016 with our colleagues from KBase: The Department of Energy Systems Biology Knowledgebase. Also, on Tuesday, January 12, 2016 from 4:00-6:10 pm in the San Diego Room, join us…
Microbial Mutualism with Orchids
Mycorrhizal fungi usually transfer nitrogen and phosphorus to plants, and receive carbohydrates. However, the orchid mycorrhizal symbiosis is unique because the mycorrhizal fungi transfer carbon to the plant, at least during early developmental stages. All orchids are dependent on fungi for seed germination and form mycorrhizae with basidiomycete fungi. These mycorrhizal fungal species are primarily…
