Abstract: The invention provides a transgenic plant having increased expression of a positive regulator protein of systemic acquired resistance (SAR), thereby enhancing the SAR response and pathogen resistance of the plant. The positive regulator protein is a component of a signal transduction pathway leading to (SAR), and is a MAP kinase protein (MPK4) substrate, and interacts with transcription factors.

Abstract: A system and method for surveillance of a physical environment. May utilise already installed equipment, such as WLAN for surveillance purposes. This makes the system cost effective to implement. Transmits a first and a second signal. The signals are received by receivers, and the received signals are compared in order to detect a difference in the signals, the difference being caused by a physical change present in the signal path between transmitter(s) and receiver(s). Does not require high spectral purity of the transmitted signals or heavy computations in order to establish that a change has occurred. Suitable for intruder alarm purposes.

Abstract: The invention relates to the field of plant propagation and more specifically to the mass propagation of plants with plant parasites, preferably of plants with green plant parasites, so called hemi-parasites. Accordingly there is provided a method for preparation of a plant comprising in successive order establishing at least one plant parasite on at least one branch of a host plant, cutting at least one branch with at least one established plant parasite, and rooting the at least one cut branch.
