The Departments of Plant Biology and Biochemistry are pleased to announce the creation of the Rabinowitch Lecture Series, which will feature guest speakers who have made key achievements in the two fields.
The transgenic papaya “SunUp” was developed in the 1990s and was widely publicized because of its ability to resist the papaya ringspot virus. Although researchers from the Ming group had identified the genomic sequence of SunUp by 2008, it was unclear where the transgenic insertions were and what effect they had. A new study has now identified these changes and how they influence the transgenic plants.
Thawing permafrost is roiling the Arctic landscape, driven by a hidden world of changes beneath the surface as the climate warms.
Across the Arctic, strange things are happening to the landscape.
Massive lakes, several square miles in size, have disappeared in the span of a few days. Hillsides slump. Ice-rich ground collapses, leaving the landscape wavy where it once was flat, and in some locations creating vast fields of large, sunken polygons.
There is much more carbon stored in Earth’s soil than in its atmosphere. A significant portion of this soil carbon is in organic form (carbon bound to carbon), called soil organic carbon (SOC). Notably, unlike the inorganic carbon in soils, the amount of SOC, and how quickly it is built up or lost, can be influenced by humans. Since its advent about 10,000 years ago, agriculture has caused a significant amount of SOC to be released into the atmosphere as carbon dioxide, contributing to climate change.
On March 16, 2022, the House Science, Space, and Technology Subcommittee on Energy held a hearing on “Bioenergy Research and Development for the Fuels and Chemicals of Tomorrow.” According to the hearing charter, the purpose of the hearing was to examine the status of bioenergy research, development, and demonstration (RD&D) activities carried out by the U.S. Department of Energy (DOE).
A team from the University of Illinois has revamped the popular crop growth simulation software BioCro, making it a more user-friendly and efficient way to predict crop yield. The updated version, BioCro II, allows modelers to use the technology much more easily and includes faster and more accurate algorithms.
The College of LAS has selected winners of this year’s teaching and advising awards. Professors, graduate students, lecturers, and an advisor have been honored for their service.
"The College of LAS is enormously proud of the recipients of this year's teaching and advising awards," said Venetria K. Patton, Harry E. Preble Dean of the College of LAS. "Teaching and advising has always required devotion, and in today's environment the challenge has been even greater. We're fortunate to have these compassionate, adaptable, and creative individuals working to make futures brighter for our students."
The 39th “Venomous” Annual Insect Fear Film Festival (IFFF) will be held on Saturday, February 26, 2022. It will be hosted by the Entomology Graduate Students Association in the Department of Entomology at the University of Illinois at Urbana-Champaign. This year’s festival will be online via Zoom at: publish.illinois.edu/uiuc-egsa/ifff. Registration is required but FREE. Activities will begin at 5 pm CST, and film introductions will start at 7:30 pm.
Arctic permafrost, if thawed, could double the amount of carbon in the atmosphere
While climate change is the primary driver of permafrost degradation in Arctic Alaska, a new analysis of 70 years of data reveals that tundra fires are accelerating that decline, contributing disproportionately to a phenomenon known as “thermokarst,” the abrupt collapse of ice-rich permafrost as a result of thawing.
Globally, plants are reaping the benefits of elevated CO2 levels in the atmosphere by increasing photosynthesis rates, a phenomenon known as the CO2 fertilization effect. However, those benefits might be offset by drier and warmer climates caused by global warming and extreme climate events. Using data collected from urban environments, researchers at Illinois have been able to study dueling effects of climate change factors on vegetation response to drought.
