Knowledge of the inheritance of C-glycosyl flavone synthesis in maize (Zea mays L.) silk tissues has been acquired through detailed genetic studies involving primarily germplasm from the Corn Belt Dent race. To test the robustness of this genetic knowledge, we examined C-glycosyl flavone synthesis in a genetically distinct germplasm pool, popcorn. C-glycosyl flavone profiles and levels and the ...

SUMMARY A fast-neutron mutagenized population of rice seedlings was screened with Magnaporthe grisea, the causal agent of rice blast disease, to identify mutants with alterations in the defence response. Three mutant lines, ebr1, ebr2 and ebr3 (enhanced blast resistance) were identified that display enhanced resistance to M. grisea. ebr1 and ebr3 also confer enhanced resistance to the bacterial...

We formulate and prove (in ZFC) a strong coloring theorem which holds at successors of singular cardinals, and use it to answer several questions concerning Shelah’s principle Pr1(μ, μ+, μ+, cf(μ)) for singular μ.

In this work we generalize primitive recursion in order to construct a hierarchy of terminating total recursive operators which we refer to as leveled primitive recursion of order i(PRi). Primitive recursion is equivalent to leveled primitive recursion of order 1 (PR1). The functions constructable from the basic functions make up PR0. Interestingly, we show that PR2 is a conservative extension ...

We characterized the accumulation patterns of Arabidopsis thaliana proteins, two CuZnSODs, FeSOD, MnSOD, PR1, PR5, and GST1, in response to various pathogen-associated treatments. These treatments included inoculation with virulent and avirulent Pseudomonas syringae strains, spontaneous lesion formation in the lsd1 mutant, and treatment with the salicylic acid (SA) analogs INA (2,6-dichloroison...

In the present study, we further studied mechanisms of transcriptional regulation of the tumor-associated carbonic anhydrase IX (CAIX). We identified PR5 in the CA9 promoter as another SP1/SP3-binding site. As shown by electromobility shift assays and block-replacement mutagenesis, PR5 is functionally equivalent to the SP1/SP3-binding PR1 identified previously. However, there is a strong requir...
