“…Although the physiological and biochemical effects of several auxinic herbicides belonging to different structural groups (e.g., 2,4-D, MCPA, picloram, and dicamba) have been well characterized in wild mustard (Deshpande and Hall 1995;Peniuk et al 1993;Webb and Hall 1995), except for dicamba (Jasieniuk et al 1995), the inheritance of resistance to other auxinic herbicides in wild mustard has not been determined. Understanding the inheritance of crossresistance to several auxinic herbicides in wild mustard will assist in determining the gene or genes controlling the resistance as well as elucidating the mechanism of evolution of resistance in this species.…”

The primary goal of this research was to determine the inheritance of cross-resistance to several groups of auxinic herbicides through classical genetic approaches using auxinic herbicide–resistant (R) and –susceptible (S) wild mustard biotypes obtained from western Canada. F1 progeny were raised from crosses between homozygous auxinic herbicide–R and –S wild mustard parental lines. The F1 and F2 populations were assessed for picloram (pyridine group) and 2,4-D (phenoxyalkanoic group) resistance or susceptibility. Analyses of the F1 as well as the F2 progeny indicate that a single dominant gene confers the resistance to picloram and 2,4-D similar to an earlier report of dicamba-based (benzoic acid group) resistance in this wild mustard biotype. Furthermore, analyses of backcross progeny in this species indicate that resistance to all three auxinic herbicides, i.e., picloram, dicamba, and 2,4-D, is determined by closely linked genetic loci. With this information on inheritance of resistance to several auxinic herbicide families, the R biotype of wild mustard offers an excellent system to isolate and characterize the auxinic herbicide–resistance gene.

“…Interaction studies of IAA, auxinic herbicides on isolated protoplasts from auxinic herbicide-resistant and -sensitive wild mustard, suggested that disruption of calcium transport was an integral part of auxinic herbicide action [41]- [43]. Calcium also plays an important role in mediating resistance to auxinic herbicides in intact seedlings [43].…”

Auxinic-like compounds have been widely used as weed control agents. Over the years, the modes of action of auxinic herbicides have been elucidated, but most studies thus far have focused on their effects on later stages of plant growth. Here, we show that some select auxins and auxiniclike herbicides trigger a rapid elevation in root cytosolic calcium levels within seconds of application. Arabidopsis thaliana plants expressing the Yellow-Cameleon (YC) 3.60 calcium reporter were treated with indole-3-acetic acid (IAA), indole-3-butyric acid (IBA), 1-naphthalene acetic acid (NAA), and two synthetic herbicides, 2,4-dichlorophenoxyacetic acid (2,4-D) and mecoprop [2-(4-chloro-2-methylphenoxy) propanoic acid], followed by monitoring cytosolic calcium changes over a 10 minute time course. Seconds after application of compounds to roots, the Ca 2+ signaling-mediated pathway was triggered, initiating the plant response to these compounds as monitored and recorded using Fluorescence Resonance Energy Transfer (FRET)-sensitized emission imaging. Each compound elicited a specific and unique cytosolic calcium signature. Also primary root development and elongation was greatly reduced or altered when exposed at two concentrations (0.10 and 1.0 µM) of each compound. Within 20 to 25 min after triggering of the Ca 2+ signal, root growth inhibition could be detected. We speculate that differences in calcium signature among the tested auxins and auxinic herbicides might correlate with their variation and potency with regard to root growth inhibition.

“…The wild mustard auxinic‐herbicide‐resistant biotypes were found to be highly resistant to picloram and dicamba (104‐fold) and moderately resistant to 2,4‐D (tenfold) and MCPA (18‐fold) 3. In spite of extensive characterization of this species at morphological, physiological, biochemical and molecular levels,4–16 the precise mechanism of auxinic herbicide resistance in wild mustard remains unknown.…”
