“…The effect of various auxinic herbicides on the binding of indoleacetic acid (IAA) to ABP preparations and seedling growth was correlated with the effect of these herbicides on whole plants, suggesting a relationship between ABP binding activity and the resistance mechanism to auxinic herbicides (Webb and Hall 1995). Deshpande and Hall (1996) found that differences between R and S protoplasts in response to IAA and auxinic herbicides at the cellular level were related to ATP-dependent auxinic herbicide-induced volume changes at the protoplast level. Resistance to dicamba in an auxinic-R biotype was controlled by a single, completely dominant nuclear gene (Jasieniuk et al 1995).…”

. An updated review of biological information is provided for Sinapis arvensis L. Native to the Old World, the species is widely introduced and naturalized in temperate regions around the world. The species occurs in all the provinces, the Northwest Territories, and the Yukon. It is an important weed of field crops in the Canadian prairies. A strongly persistent seedbank, competitive annual growth habit and high fecundity all contribute to its weedy nature and ensure that it will be a continuing problem. Several cases of herbicide resistance have been documented for natural populations of S. arvensis in Canada, including biotypes resistant to: i) Group 2 herbicides, which inhibit acetolactate synthase (ALS), from Manitoba in 1992 and Alberta in 1993; ii) Group 4 herbicides or synthetic auxins from Manitoba in 1991; and iii) Group 5 herbicides, which inhibit photosynthesis at photosystem II, from Ontario in 1983. The species is a close relative of Brassica nigra (L.) Koch, black mustard, and is capable of limited genetic exchange with the Brassica crop species under laboratory hybridization conditions either by conventional crossing or with the aid of ovary/embryo recovery techniques.

“…A precise mechanism of auxinic herbicide resistance has not been determined for any species, although a biotype of wild mustard (Sinapis arvensis L. syn. Brassica kaber L.) with resistance to dicamba, MCPA, and other auxinic herbicides has been thoroughly characterized (Deshpande and Hall 1996;Wang et al 2001;Webb and Hall 1995). Resistance in this biotype is thought to be as-sociated with reduced herbicide binding to auxin-binding proteins (Zheng and Hall 2001).…”

A hyperspectral imager was used to differentiate herbicide-resistant versus herbicide-susceptible biotypes of the agronomic weed kochia, in different crops in the field at the Southern Agricultural Research Center in Huntley, Montana. Controlled greenhouse experiments showed that enough information was captured by the imager to classify plants as either a crop, herbicide-susceptible or herbicide-resistant kochia. The current analysis is developing an algorithm that will work in more uncontrolled outdoor situations. In overcast conditions, the algorithm correctly identified dicamba-resistant kochia, glyphosate-resistant kochia, and glyphosate-and dicamba-susceptible kochia with 67%, 76%, and 80% success rates, respectively. © The Authors.

“…Altered herbicide absorption, translocation and metabolism have been ruled out as mechanisms of resistance to mecoprop in Stellaria media (common chickweed) (Coupland, 1994), dicamba and picloram in Sinapis arvensis (syn Brassica kaber) (wild mustard) (Webb & Hall, 1995) and dicamba in K. scoparia (kochia) (Cranston et al, 2001). In S. arvensis, ATP-dependent auxin-and auxinic herbicide-induced volume changes in resistant protoplasts were less than in susceptible protoplasts (Deshpande & Hall, 1996), and dicamba binding to ABPs was less competitive with IAA in resistant than in susceptible biotypes (Webb & Hall, 1995). Calcium flux after herbicide treatment was also different between biotypes, indicating the presence of alterations in auxin-mediated signal transduction .…”
