Wrong Place, Wrong Time: Why Zika Virus Hijacks a Protein Needed for Brain Growth

The mosquito-borne Zika virus is known for causing microcephaly, a birth defect in which abnormal brain development results in a smaller-than-expected head. A new study published Jan. 13 in mBio shows that the Zika virus hijacks a host protein called ANKLE2, which happens to be important for brain development, to assist its own reproduction. Because Zika, unlike most related viruses, can cross the placenta, this can have disastrous consequences in pregnancy.

From the Dean: Creativity, Ingenuity and Dedication

An Unseen Battle: Changes Among Plants

A battle around the world is raging between plants and the changing environment, and UC Davis researchers are on the front lines.

For example, the microbes are constantly creating new types of illnesses, while the plants — sometimes with the help of breeders — are developing new immunities.

It’s something plant geneticist Luca Comai, Ph.D. ’80, a distinguished professor of plant biology, has seen firsthand through his decades of research into plant chromosomes.

Christmas Trees’ Distinctive Aroma Helps Ward off Pathogens and Pests

Each year, nearly 30 million Americans purchase a real tree for the holidays. Growing the perfect Christmas tree takes about seven years, during which farmers need to keep insects, fungal pathogens and hungry deer at bay. While researchers suspect the distinctive piney smell the trees emit plays a role in deterring these pests, not all trees smell the same, and which chemical blends confer resistance is unclear.
