Computational analysis shows that plant hormones often go it alone

...who lived by the motto "All for one, one for all," plant hormones prefer to do their own thing. For years, ...nd whether pathways activated by growth-regulating plant hormones converge on a central growth regulatory module. Now, the cooperation model is challenged by...

Bacteria can help predict ocean change

... of water temperature, salinity, nutrient content, plant matter and other variables. The researchers found they could predict the makeup of the bacterial population by the conditions in the water more than four times in five. A majority of bacterial species came and went predictably, Fuhrman said. A sm...

When the going gets tough, slime molds start synthesizing

Researchers uncover new mechanism of tumor suppressor

...ecular mechanism of histone H3K4me3 recognition by plant homeodomain of ING2, was conducted in Kutateladze's laboratory with the assistance of graduate student Pedro Peña and research assistant Foteini Davrazou. Other co-authors include Rui Zhao, PhD, an assistant professor in the UCDHSC Department of Bioc...

DOE JGI finishes 100th microbial genome

...ical importance to DOE because they can break down plant materials to produce such useful sources of energy as ethanol and hydrogen, and clean up toxic waste sites. We know that microbes can perform these and a multitude of other amazing tasks and with the proper technology we can harness these capabilitie...

It's all in the genes

...m's group worked with the Bureau of Reclamation to plant about 10,000 trees at the Cibola National Wildlife Refuge along the lower Colorado River, about 20 miles south of Blythe, Calif., to examine how genetic diversity at the stand level influences communities and ecosystem processes. "The Bureau of Re...

Insect predation sheds light on food web recovery after the dinosaur extinction

...l evidence shows that at certain times and places, plant and insect diversity were severely out of balance,...000 years, there was very low insect predation and plant diversity. We know that 9 million years afterwards, there was renewed diversity in both plants and i...

Food-crop yields in future greenhouse-gas conditions lower than expected

...ize and sorghum," said Stephen P. Long, a U. of I. plant biologist and crop scientist. FACE technology, such as the SoyFACE project at Illinois, allows researchers to grow crops in open-air fields, with elevated levels of carbon dioxide simulating the composition of the atmosphere projected for the year 2...

Marine 'dead zone' off Oregon is spreading

...conditions ?can change. This allows huge masses of plant growth to die, decay and in the process consume even more of the available oxygen near the sea floor, causing hypoxic conditions for marine life. The first event in 2002 caused a massive die-off of fish and invertebrate marine species on the central...

DNA: Bacteria's survival ration

... aren't we up to our ears in DNA, in ribosomes, in plant protein? "A lot of decay is microbial, and nobody ever thinks about it." Finkel calls this phenomenon "nutritional competence" to distinguish it from natural competence, defined as the ability of cells to assimilate waste DNA in order to mutate or ...
