Factors Affecting Germination of Puccinia jaceae var. solstitialis Teliospores from Yellow Starthistle.
ABSTRACT The rust fungus Puccinia jaceae var. solstitialis is a candidate for biological control of yellow starthistle (YST). Part of the risk assessment includes determining if safflower seedlings are susceptible to infection by teliospores of P. jaceae. A protocol for germination of P. jaceae teliospores is needed to verify that teliospores used in comparative studies are viable. The protocol...
متن کاملUse of digital images to differentiate reactions of collections of yellow starthistle (Centaurea solstitialis) to infection by Puccinia jaceae
Yellow starthistle (YST) (Centaurea solstitialis) is an invasive weed in the USA and a target of classical biological control. However, the precise geographical origin(s) of YST in the USA is not known. This study was conducted to learn whether the origin(s) of YST in California, USA could be determined on the basis of digital image analysis (DIA) of YST reactions to isolates of the rust Puccin...
متن کاملGeneration of molecular markers for the identification of isolates of Puccinia jaceae, a potential biological control agent of yellow starthistle
Yellow starthistle (Centaurea solstitialis L.) (YST) is an important invasive plant that infests millions of hectares in the western USA and Canada. Isolates of the exotic rust fungus Puccinia jaceae have been evaluated as a potential biological control for YST. The objectives of this study were to characterize isolates of P. jaceae by amplified fragment length polymorphic (AFLP) DNA analysis a...
متن کاملIn vitro culturing of yellow starthistle (Centaurea solstitialis) for screening biological control agents
In an effort to design a bioassay to screen for biocontrol pathogens and their toxins, procedures were developed to produce calli of yellow starthistle (YST), Centaurea solstitialis (Asteraceae), on solid and liquid media. Three Murashige and Skoog (MS) media with different hormone additives were compared for their effects on the growth of the YST calli. The most effective medium was made of MS...
متن کاملA Structural Growth Model of the Invasive Weed Species Yellow Starthistle, Centaurea solstitialis L
Yellow starthistle (Centaurea solstitialis L.) is a summer-flowering annual plant of the family Asteraceae, and a significant weed of roadsides, pasture and grasslands in California. It is also distributed, though with less economic and ecological significance, throughout the US and in other temperate parts of the world. Yellow starthistle grows vigorously during the dormant period for most nat...
