Concurrent evolution of seed dormancy and herbicide resistance in field populations of dominant weed species in Western Australian cropping systems
This study evaluates the interaction among developing herbicide resistance, seed size and seed dormancy of ripgut brome, wild oat and hare barley collected from within intensively-managed fields (in-crop) in comparison with populations in surrounding ruderal (non-crop disturbed) areas with no history of exposure to herbicides within the Western Australian grainbelt.
Transfer of resistance alleles from herbicide-resistant to susceptible grass weeds via pollen-mediated gene flow
This paper reviews the reproductive biology, herbicide-resistant biotypes, pollen-mediated gene flow (PMGF), and potential for transfer of alleles from herbicide-resistant to herbicide-susceptible grass weeds including barnyard grass, creeping bentgrass, Italian ryegrass, Johnson grass, rigid (annual) ryegrass, and wild oats.
Mechanical scarification technique breaks seed coat-mediated dormancy in wild oat (Avena fatua)
Wild oat is a herbicide resistance-prone global weed species that causes significant economic losses in dryland and horticultural agriculture. As a result, there has been a significant research effort in controlling this species.
Herbicide resistance-endowing ACCase gene mutations in hexaploid wild oat (Avena fatua): insights into resistance evolution in a hexaploid species
Many herbicide-resistant weed species are polyploids, but far too little about the evolution of resistance mutations in polyploids is understood. Hexaploid wild oat (Avena fatua) is a global crop weed and many populations have evolved herbicide resistance.
Herbicide Resistance Endowed by Enhanced Rates of Herbicide Metabolism in Wild Oat (Avena spp.)
The biochemical basis of resistance to the acetyl-coenzyme A carboxylase (ACCase)-inhibiting herbicide diclofop-methyl was investigated in a resistant wild oat population (R1), which does not exhibit a resistant ACCase.
Herbicide resistance-endowing ACCase gene mutations in hexaploid wild oat (Avena fatua): Insights into resistance evolution in a hexaploid species” Heredity 2012
Many herbicide-resistant weed species are polyploids, but far too little about the evolution of resistance mutations in polyploids is understood. Hexaploid wild oat (Avena fatua) is a global crop weed and many populations have evolved herbicide resistance.
Wet-dry cycling extends seed persistence by re-instating antioxidant capacity
Seeds in the field experience wet-dry cycling that is akin to the well-studied commercial process of seed priming in which seeds are hydrated and then re-dried to standardise their germination characteristics.
