Plants respond similarly to signals from friends, enemies

... paper, in the lab of Dr. Nina Allen, professor of botany and co-author of the paper. Weerasinghe first observed the changes in the plants triggered by signals from rhizobia, called Nod factors, and then saw the similar changes occurring when plants were signaled by root-knot nematodes. In the paper, the re...

Plants defy Mendel's inheritance laws, may prompt textbook changes

...ent now at Butler University; and Jessica Young, a botany and plant pathology laboratory technician. Lolle, a Purdue research scientist, is currently at the National Science Foundation. ...

No relief for Pacific Northwest drought

...gist with the U.S. Forest Service and professor of botany at OSU. Severe drought does not automatically translate into major fires, said Neilson and colleague James Lenihan, a fire and ecosystem modeler. "It takes ignition sources such as lightning storms to trigger multiple fires, and that doesn't always...

Genetic discovery could lead to drought-resistant plants

...Current Biology. "It's very exciting," says U of T botany professor and senior author Malcolm Campbell. "This is a gene that helps regulate carbon dioxide uptake. If plants are the Earth's lungs, we've just discovered a key piece of information about how the Earth breathes." The pores on the surface of pla...

Biologists discover new pathway into plant cells

...xisted," said Lynda Ciuffetti, an OSU professor of botany and plant pathology. "Viruses and bacteria have been known to bring proteins into cells, but this is just a protein by itself crossing the cell wall barrier without disrupting its integrity. This is a significant fundamental advance in our understand...

Pleasing plant shapes explained by new computer model

...small white-flowered plant that is to the world of botany what the fruit fly and white mouse are to zoology. The scientists believe their model will enhance biological experiments by providing a tool botanists can use to complement and interpret their traditional laboratory experiments. It also promises to...

Gene thwarts some pathogens, gives access to others, could save crops

...ant molecular biologist and assistant professor of botany and plant pathology. "The mutant plant that doesn't have BIK1 actually shows decreased immunity to two pathogens, including Botrytis. But unexpectedly, it is completely resistant to virulent strains of the biotrophic bacteria." The study of BIK1's r...
