Rice phytochelatin synthases Os PCS 1 and Os PCS 2 make different contributions to cadmium and arsenic tolerance

Partition Repositories for Partition Cloning - OS Independent Software Maintenance in Large Clusters of PCs

As a novel approach to software maintenance in large clusters of PCs requiring multiple OS installations we implemented partition cloning and partition repositories as well as a set of OS independent tools for software maintenance using entire partitions, thus providing a clean abstraction of all operating system configuration state. We identify the evolution of software installations (differen...

Tolerance to toxic metals by a gene family of phytochelatin synthases from plants and yeast.

Phytochelatins play major roles in metal detoxification in plants and fungi. However, genes encoding phytochelatin synthases have not yet been identified. By screening for plant genes mediating metal tolerance we identified a wheat cDNA, TaPCS1, whose expression in Saccharomyces cerevisiae results in a dramatic increase in cadmium tolerance. TaPCS1 encodes a protein of approximately 55 kDa with...

Diverse OS Rejuvenation for Intrusion Tolerance

Proactive recovery is technique that periodically rejuvenates the components of a replicated system. When used in the context of intrusion-tolerant systems, in which faulty replicas may be under control of some adversary, it allows the removal of intrusions from the compromised replicas. However, since the set of vulnerabilities remains the same, the adversary can take advantage of the previous...

Cadmium tolerance and phytochelatin content of Arabidopsis seedlings over-expressing the phytochelatin synthase gene AtPCS1

Previous studies demonstrated that expression of the Arabidopsis phytochelatin (PC) biosynthetic gene AtPCS1 in Nicotiana tabacum plants increases the Cd tolerance in the presence of exogenous glutathione (GSH). In this paper, the Cd tolerance of Arabidopsis plants over-expressing AtPCS1 (AtPCSox lines) has been analysed and the differences between Arabidopsis and tobacco are shown. Based on th...
