Rice (Oryza sativa) is sensitive to salinity, which affects one-fifth of irrigated land worldwide. Reducing sodium and chloride uptake into rice while maintaining potassium uptake are characteristics that would aid growth under saline conditions. We describe genetic determinants of the net quantity of ions transported to the shoot, clearly distinguishing(More)
The level of resistance to the reniform nematode Rotylenchulus reniformis conferred on Arabidopsis thaliana by transgenic expression of proteinase inhibitors (PI) was studied over 40 days of infection. A cysteine PI differing from Oc-I expressed in rice seed by one amino acid (Oc-IΔD86) had a considerable effect. It reduced parasite density and fecundity to(More)
Recently seven National Academies of Science produced a report on transgenic plants and world agriculture. The report provides scientific perspectives to the ongoing public debate about the potential role for transgenic technology in world agriculture. In this article, we develop the themes of the report and emphasize the potential for future genetically(More)
We provide evidence from a 5-year study to show that a single concerted effort at the start of undergraduate study can have a clear and lasting effect on the attitudes of students toward plant science. Attendance at a week-long residential plant science summer school in the first year of an undergraduate degree resulted in many students changing courses to(More)
