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 ...
LSD1 regulates salicylic acid induction of copper zinc superoxide dismutase in Arabidopsis thaliana.
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...
The insect pathogenic fungus Metarhizium anisopliae produces several extracellular cuticle-degrading proteases and evidence is consistent that one of these, a chymoelastase PRl, is a determinant of pathogenicity. We have shown previously that the wide-domain regulatory circuits of carbon and nitrogen derepression regulate PRI production. In the present work we have established in addition that ...
Mycoinsecticides are being used for the control of many insect pests as an environmentally acceptable alternative to chemical insecticides. A key aim of much recent work has been to increase the speed of kill and so improve commercial efficacy of these biocontrol agents. This might he achieved by adding insecticidal genes to the fungus, an approach considered to have enormous potential for the ...
As a resistance elicitor, riboflavin (vitamin B2) protects plants against a wide range of pathogens. At molecular biological levels, it is important to elucidate the signaling pathways underlying the disease resistance induced by riboflavin. Here, riboflavin was tested to induce resistance against virulent Pseudomonas syringae pv. Tomato DC3000 (Pst DC3000) in Arabidopsis. Results showed that r...
Abnormal genome hypermethylation participates in the tumorigenesis and development of prostate cancer. Prostate cancer cells highly express DNA methyltransferase 3 (DMNT3) family genes, essential for maintaining genome methylation. In the present study, multi-target siRNA, based on the homologous region of the DNMT3 family, was designed for the in vitro investigation of its effects on the proli...
