Background: Because herbicide resistance evolves in very large populations over periods of many years, modelling is an important tool for investigating the dynamics of the problem. The Diversity model tracks the simultaneous evolution of resistance to multiple herbicides, using multiple genetic pathways, in several weed species at once. Tracking multiple species and simultaneous resistances is an important development in resistance modelling.

, common sowthistle, is an asteraceous weed in Australian agricultural systems and has recently developed resistance to glyphosate. We present the complete chloroplast sequence of reconstructed from Illumina whole genome shotgun sequencing. This is the first complete chloroplast genome available for the genus .

Background: This study takes a whole-transcriptome approach to assess gene expression changes in response to glyphosate treatment in glyphosate-resistant fleabane. We assessed gene expression changes in both susceptible and resistant lines so that the glyphosate death response could be quantified, and constitutively expressed candidate resistance genes identified. There are three copies of the glyphosate target site (5-enolpyruvylshikimate-3-phosphate; EPSPS) gene in Conyza and because Conyza bonariensis is allohexaploid, there is a baseline nine copies of the gene in any individual.

(windmill grass) and (feathertop Rhodes grass) are both weedy grass species that have developed resistance to glyphosate in Australia. This paper describes the complete chloroplast genomes of these two species generated by high throughput shotgun sequencing. The chloroplast genome of is 135,584 bp and is 134,561 bp; both have a GC content of 38%.
