New research suggests 'unique duality' of wild and domesticated yeasts

New research from the University of Georgia suggests our familiarity with yeast traces back to the footsteps of our ancestors. Humans domesticated baker’s yeast as early as 7000 BCE to make bread, beer, wine and sake. However, wild varieties of the same yeast species also live on trees. These domesticated and wild yeast look different genetically, but UGA researchers wanted to explore possible links between the two: “Other studies had just…

UGA plant biologist leads new advances in biotech

The evolutionary lineage leading to Amborella diverged from all other flowering plant lineages approximately 150 million years ago. In 2013, an international research team co-led by UGA Plant Biology faculty member Jim Leebens-Mack and collaborators announced the newly sequenced genome of the Amborella trichopoda plant became the foundation for comparative analyses of genes tracing back to the origin of flowering plants and earlier.…

Ancestry of Sanford Stadium hedges goes into the lab

In a terrific story combining genome analysis, a love for the hedges and UGA history— a Franklin College faculty member and his students found that the same family of hedges have stood tall for nearly 100 years: Plant biology professor and hedges researcher James Leebens-Mack decided to sequence the genome of the Sanford Stadium hedges. His goal was to combine service-learning with his own areas of research, comparative genome biology and the…

Getting to the roots of climate solutions

As responses to climate change move toward adaptive solutions, plant genetics research faculty at the University of Georgia are seeking plant-based solutions. Some of these colleagues – from across campus, within and beyond the Franklin College – conduct studies at the cellular level, while others investigate plants as whole organisms. Still others are exploring how epigenetics shape entire ecosystems. And while a number of UGA geneticists…

Bensasson uses yeast to unlock life’s greatest mysteries

What comes to mind when you think of yeast? To a baker, it might mean the ability to make their dough rise. A brewmaster might associate it with the fermentation of beer and wine. Many others may associate these types of fungus with one dreaded infection or another. Yeast serves many functions. For the University of Georgia’s Douda Bensasson, it’s all of these—and more. An associate professor in the Franklin College of Arts & Science’s…

Model mycology: UGA scientists fight fungi for the rest of us

It starts out with a cough and slightly slurred speech. Then come the muscle spasms and dramatic mood shifts. In HBO’s hit show “The Last of Us,” these are the beginning signs that a human has contracted a fungal infection that turns people into zombies and rips through the fabric of modern society. The premise may sound improbable, but it is based on a very real fungus that really does infect brains and bodies, turning its victims into mindless…

Chung studies how microbes shape ecosystems

University of Georgia plant biologist and ecologist, Anny Chung studies the smaller things in life to understand how microscopic organisms can influence entire ecosystems. As an assistant professor jointly appointed in the College of Agricultural and Environmental Sciences Department of Plant Pathology and the Franklin College of Arts and Sciences Department of Plant Biology, Chung studies how plant-microbe interactions…

New vaccine targets life-threatening fungal infections

A new study from University of Georgia researchers describes a vaccine that could be the first clinically approved immunization to protect against invasive fungal infections, a growing concern as antifungal drug resistance increases:   The experimental vaccine is designed to protect against the three most common fungal pathogens that are responsible for more than 80% of fatal fungal infections. The study tested the vaccine’s efficacy…

Genome evolution in the modern fern

Defying all expectations, a fern no larger than a dinner plate currently holds the title for highest chromosome count, with a whopping 720 pairs crammed into each of its nuclei. This penchant of ferns for hoarding DNA has stumped scientists, and the intractable size of their genomes has made it difficult to sequence, assemble and interpret them. Two new papers published in the journal Nature Plants are rewriting history with the first full-…

Antifungal resistance: From “Big Chicken” to Big Tulip

The Genes to Genomes blog reports on recent research by UGA fungal biologists Michelle Momany and Marin Brewer, who reported in their findings that Aspergillus fumigatus isolated from clinical settings is resistant to agricultural fungicides. Infections have long been a deadly problem for hospital patients. Though modern medicine has an impressive array of antimicrobial drugs at its disposal, pathogens continue to evolve resistance,…

When pollen comes of age

New research from the University of Georgia has determined when pollen comes of age and begins expressing its own genome, a major life cycle transition in plants. Each grain of pollen is actually its own multicellular organism – with two to 40 cells, depending on the species. Pollen expresses its own genome and is genetically distinct from its parent plant. That means pollen grains from a single flower can have different traits and…

Agricultural fungicides may be driving resistance

New research from the University of Georgia has shown, for the first time, that compounds used to fight fungal diseases in plants are causing resistance to antifungal medications used to treat people. The study focused on Aspergillus fumigatus, the fungus that causes aspergillosis, a disease that causes life-threatening infections in 300,000 people globally each year. Published in G3: Genes, Genomes, Genetics, the study …

Genetics research paves way for better corn plants

The newly assembled genomes of 26 different genetic lines of corn illustrate the crop’s rich genetic diversity and lay the groundwork for a better understanding of what genetic mechanisms account for crop traits prized by farmers. The mapping of the 26 genomes, published recently in the journal Science, was a team effort co-led by University of Georgia’s Kelly Dawe that will help scientists piece together the puzzle of corn genetics.…

Adapting Roots to a hotter planet could ease pressure on food supply

The shoots of plants get all of the glory, with their fruit and flowers and visible structure. But it's the portion that lies below the soil — the branching, reaching arms of roots and hairs pulling up water and nutrients — that interests plant physiologist and computer scientist, Alexander Bucksch, associate professor of Plant Biology at the University of Georgia. The health and growth of the root system has deep implications for our…
