The cultivation of tomato (Solanum lycopersicum) plants for their edible fruits is a worldwide industry that was valued at over $58.7B in 2011. Traditional breeding has predominantly focused on increasing fruit yield or the accumulated concentrations of health-promoting phytochemicals, such as the antioxidant Iycopene. As a result, tomato crops remain susceptible to a large number of potentially devastating diseases which cause significant economic losses to commercial producers. These diseases are incited by a diverse group of microorganisms including bacteria, fungi, nematodes and oomycetes. DNA microarrays are a rapid, sensitive and relatively low cost molecular tool. They can be used to simultaneously detect a large number of PCR-amplified target DNA fragments based on their hybridisation to pre-designed short (~30 bp) complementary oligonucleotide capture probes. Capture probes are commonly designed using barcode regions in the genome and rely on the presence of heterogeneous sequence. Several applications of microarrays have been proposed, including their use for detecting pathogen occurrence and monitoring environmental microbial populations. The ArrayTube platform consists of a 3 x 3 mm glass microprobe array biochip embedded within a modified 1.5 ml Eppendorf-style tube. It provides a discrete environment in which the entire hybridisation and enzyme-catalysed precipitation staining reactions can occur. Detection of hybridised probes is achieved by the acquisition of grey-value transmission data using a specialised ArrayTube Reader device.
