Glyphosate Resistance in Tall Waterhemp (Amaranthus tuberculatus) from Mississippi is due to both Altered Target-Site and Nontarget-Site Mechanisms (2013, background): “…indicated noticeable fitness differences where glyphosate-resistant plants from a population produced fewer but larger seeds compared to -susceptible plants from the same population (Pedersen et al. 2007); however, there were no growth differences between the resistant and susceptible populations.”
Modelling evolution and management of glyphosate resistance in Amaranthus palmeri (2011, background): “Similarly, the implications of costs of 589 resistance for glyphosate have not been investigated here, though a number of studies have 590 begun to demonstrate small costs in the absence of glyphosate selection (Baucom & 591 Mauricio, 2004; Pedersen et al., 2007; Preston et al., 2009).”
Glyphosate-Resistant Italian Ryegrass (Lolium multiflorum) in California: Distribution, Response to Glyphosate, and Molecular Evidence for an Altered Target Enzyme (2008, background): “Attempts to confirm fitness costs associated with glyphosate resistance in other weeds have been less clearcut, however (reviewed in Pedersen et al. 2007).”
A Decade of Glyphosate-Resistant Lolium around the World: Mechanisms, Genes, Fitness, and Agronomic Management (2009, unknown): “Using this technique, Pedersen et al. (2007) showed that glyphosate-resistant rigid ryegrass plants produced fewer, but larger, seed than their susceptible counterparts.”
Role of Translocation as A Mechanism of Resistance to Glyphosate (2009, background): “GR rigid ryegrass produced smaller seed compared with a GS biotype, which could be due to less-efficient translocation of photosynthate in the resistant biotype (Pedersen et al. 2007) Importantly, once we understand the mechanisms involved in reduced glyphosate translocation, we may also have a bett”
