Investigating the cost of adaptation in Amaranthus tuberculatus populations with evolved resistance to glyphosate [PDF]

Amaranthus tuberculatus (Common Waterhemp) is a prevalent, problematic weed in Midwestern USA, where genetically-modified crops are widely grown, resulting in multiple annual applications of glyphosate.

Successive increases in the resistance of Drosophila to viral infection through a transposon insertion followed by a Duplication [PDF]

, 2011
To understand the molecular basis of how hosts evolve resistance to their parasites, we have investigated the genes that cause variation in the susceptibility of Drosophila melanogaster to viral infection.

Weed resistance diagnostic technologies to detect herbicide resistance in cerealgrowing areas. A review

Julius-Kühn-Archiv, 2012
Cereals are major crops used for food and feed. By 2050, the world population is expected to be close to 10 billion requiring a doubling of the food production from a fixed area of arable land.

The presence of two different target-site resistance mechanisms in individual plants of Alopecurus myosuroides Huds., identified using a quick molcular test for the characterisation of six ALS and seven ACCase SNPs

, 2013
BACKGROUND Target-site resistance to ALS- and ACCase-inhibiting herbicides in the grass weed Alopecurus myosuroides is associated with well-characterised allelic variants encoding ALS- and ACCase-based resistance.

Six amino acid substitutions in the carboxyl-transferase domain of the plastidic acetyl-CoA carboxylase gene are linked with resistance to herbicides in a Lolium rigidum population [PDF]

, 2006
• The molecular basis of an acetyl-CoA carboxylase (ACCase) target-based resistant Lolium rigidum population (WLR 96) was studied here. • The carboxyl-transferase domain of the plastidic ACCase gene from resistant individuals was amplified by PCR and ...

Regional diversity of the ALS gene and hormesis due to tribenuron-methyl in Centaurea cyanus L.

Scientific Reports
Centaurea cyanus L. is a common field weed in Eastern Europe but only in Poland biotypes of this species with resistance to acetolactate synthase (ALS) inhibitors have been confirmed.

Insecticide resistance and its association with target-site mutations in natural populations of Anopheles gambiae from eastern Uganda

, 2009
Insecticide resistance in Anopheles gambiae threatens the success of malaria vector control programmes in sub-Saharan Africa. In order to manage insecticide resistance successfully, it is essential to assess continuously the target mosquito population ...

Target Site–Based and Non–Target Site Based Resistance to ALS Inhibitors in Palmer Amaranth (Amaranthus palmeri)

, 2017
Resistance to acetolactate synthase (ALS)-inhibitor herbicides due to continuous and repeated selection is widespread in many troublesome weed species, including Palmer amaranth, throughout the United States.

Resistance profile of herbicide-resistant Alopecurus myosuroides (black-grass) populations in Denmark

, 2015
Alopecurus myosuroides Huds is one of the most important grass-weeds in North-western Europe and is also the most important herbicide-resistant weed species in European agricultural systems. Fifty-three Danish A.
