A complementary DNA encoding a salicylic acid (SA)-binding protein has been cloned. Its properties suggest involvement in SA-mediated induction of systemic acquired resistance (SAR) in plants. The sequence of the protein is similar to that of catalases and the protein exhibits catalase activity. Salicylic acid specifically inhibited the catalase activity in(More)
NPR1 is a critical component of the salicylic acid (SA)-mediated signal transduction pathway leading to the induction of defense genes, such as the pathogenesis-related (PR)-1 gene, and enhanced disease resistance. Using a yeast two-hybrid screen, we identified several NPR1-interacting proteins (NIPs). Two of these NIPs are members of the TGA/OBF family of(More)
Salicylic acid (SA) plays a critical signaling role in the activation of plant defense responses after pathogen attack. We have identified several potential components of the SA signaling pathway, including (i) the H(2)O(2)-scavenging enzymes catalase and ascorbate peroxidase, (ii) a high affinity SA-binding protein (SABP2), (iii) a SA-inducible protein(More)
Studies in our laboratory as well as others strongly suggest that salicylic acid (SA) plays an important signaling role in plant defense against pathogens. We have found that increases in endogenous SA levels correlates with both resistance of tobacco to infection with tobacco mosaic virus and induction of defense-related genes such as that encoding(More)
In many plant-pathogen interactions, resistance is associated with the synthesis and accumulation of salicylic acid (SA) and pathogenesis-related (PR) proteins. At least two general classes of mutants with altered resistance to pathogen attack have been identified in Arabidopsis. One class exhibits increased susceptibility to pathogen infection; the other(More)
Improvements in transformation techniques and the isolation of many genes whose transcripts or protein products either have antimicrobial or insecticidal activity or are involved in the synthesis of products with such activities have provided valuable tools for engineering resistance in plants. Future exploitation of this technology should provide an(More)
Conillon is a middleware written in Java that allows for distribution of computationally complex tasks across several desktop workstations. In this paper, we present results of extensive experiments and analyze the performance of Conillon running four different jobs on up to 64 desktop computers. Our results show that Conillon achieves an average speed up(More)
In this paper we propose an open source architecture, which enables the scientific community to implement and execute highly demanding CPU tasks in distibuted way. The system main idea is to use idle time of a set of volunteers, and distribute in a smart and transparent way the work to the volunteers that perform the real work. Contrary to the existing(More)
