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.…

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-…

How corn breaks genetics laws

In a new paper published in the journal Cell, genetics professor Kelly Dawe solves a long-sought mystery: Modern genetics is based on the idea that genes are passed on to progeny in a predictable fashion, as first described by 19th-century Austrian botanist Gregor Mendel. He determined that genes exist in pairs, and each one of the two has an equal chance of being transmitted to the next generation. However, in rare exceptions, chromosomes…
