A test for Tomato Root Mat Disease caused by Rhizobium rhizogenes, a gram-negative soil bacterium that contains root-inducing (Ri) plasmids which can lead to over-abundant growth of roots in tomatoes and cucumbers.
Blackleg is caused by a number of pectolytic bacteria, including Pectobacterium and Dickeya species, that have the ability to breakdown plant cell walls. It is a disease which affects all sectors of the UK potato industry.
DNA sequencing of 16S rDNA or housekeeping genes can be performed to identify bacterial isolates to a species or pathovar level. Testing can be performed on fresh isolates sent in to our labs or as an additional service to identify bacteria isolated from a sample sent in for testing.
