Marine pest incursions can cause significant ongoing damage to aquaculture, biodiversity, fisheries habitat, infrastructure and social amenity. They represent a significant and ongoing economic burden. Marine pests can be introduced by several vectors including aquaculture, aquarium trading, commercial shipping, fishing, floating debris, mining activities(More)
OBJECTIVES To assess the breadth, depth, and perceived importance of pharmacogenomics instruction and level of faculty development in this area in schools and colleges of pharmacy in the United States. METHODS A questionnaire used and published previously was further developed and sent to individuals at all US schools and colleges of pharmacy. Multiple(More)
Phoma koolunga sp. nov. is described, having been isolated from ascochyta blight lesions on field pea (Pisum sativum) in South Australia. The species is described morphologically and sequences of the internal transcribed spacer region compared with those of the accepted pathogens causing ascochyta blight of field peas. P. koolunga was distinct from(More)
The Rlnn1 locus, which resides on chromosome 7A of bread wheat (Triticum aestivum L.) confers moderate resistance against the root lesion nematode Pratylenchus neglectus. Prior to this research, the exact linkage relationships of Rlnn1 with other loci on chromosome 7A were not clear and there were no simple codominant markers available for selection of(More)
Root systems are critical for water and nutrient acquisition by crops. Current methods measuring root biomass and length are slow and labour-intensive for studying root responses to environmental stresses in the field. Here, we report the development of a method that measures changes in the root DNA concentration in soil and detects root responses to(More)
The root-lesion nematodes (RLN) Pratylenchus thornei and P. neglectus are widely distributed in Australian grain producing regions and can reduce the yield of intolerant wheat cultivars by up to 65 %, costing the industry ~123 M AUD/year. Consequently, researchers in the northern, southern and western regions have independently developed procedures to(More)
In Mediterranean-type environments, effective capture of intermittent rainfall is important for crop drought tolerance. Two wheat genotypes RAC875 and Kukri differing in drought tolerance vary in several shoot traits and grain yield. Little is known about root traits contributing to drought tolerance. This study examined dynamic root responses to cyclic(More)
Grape phylloxera, Daktulosphaira vitifoliae (Fitch) (Hemiptera Phylloxeridae) is a damaging pest of grapevines (Vitis spp.) around the world, and the management of this pest requires early detection of infestations. Here, we describe the development and validation of a sensitive DNA test for grape phylloxera that can be applied to soil. Species-specific(More)
BACKGROUND Sudden death syndrome (SDS) of soybean caused by Fusarium virguliforme spreads and reduces soybean yields through the North Central region of the U.S. The fungal pathogen and Heterodera glycines are difficult to manage. METHODOLOGY/PRINCIPAL FINDINGS The objective was to determine the contributions of H. glycines and F. virguliforme to SDS(More)
