Herdina

TL;DR: Issues that were addressed in establishing the DNA-based soil testing service in Australia are discussed and the training and accreditation programs that have been established are explained to ensure that results are interpreted adequately at the farm level.

TL;DR: This review provides a brief account of the techniques traditionally used for detection and describes developments in molecular-based methods for the detection and surveillance of marine pest species.

TL;DR: The utility of the method for quantitative root studies was demonstrated in an experiment to investigate the effect of lime on root growth of acid-soil resistant and sensitive perennial grasses grown together in an aluminium-toxic soil.

TL;DR: Estimates of the amount of Ggt in the soil using a DNA-based assay reflect both live and dead populations of the fungus, and the rate of breakdown of DNA of the dead fungus is very high and the presence of dead fungi in roots probably a rare event so the DNA from dead fungus probably contributes little to the total DNA level.

TL;DR: The development of a method that measures changes in the root DNA concentration in soil and detects root responses to drought in controlled environment and field trials and develops a procedure for correcting genotypic differences in the copy number of the target DNA sequence.
