Resistance to the herbicide 2,4-D in Sisymbrium orientale conferred by a deletion mutation in the degron tail of IAA2

ABSTRACT: Resistance to the phenoxy synthetic auxin herbicide 2,4-D is conferred by a deletion mutation in the degron tail of IAA2. An RNA-Seq experiment was used to assemble a reference transcriptome for the weed species Sisymbrium orientale, to quantify gene expression, and to identify sequence variants in the alignments. A 27 bp deletion was identified in the IAA2 gene. Forward genetics supported the role of this deletion mutation in resistance. The IAA2 deletion allele was transformed into Arabidopsis thaliana to confirm that it conferred 2,4-D resistance.

Insights into ROS-dependent signalling underlying transcriptomic plant responses to the herbicide 2,4-D

Project description:The synthetic auxin 2,4-dichlorophenoxyacetic acid (2,4-D) functions as an agronomic weed control herbicide. High concentrations of 2,4-D induce plant growth defects, particularly leaf epinasty and stem curvature. Although the 2,4-D phenotype is associated with ROS production, little is known about ROS-dependent signalling. In this study, by using T-DNA Arabidopsis mutants to silence peroxisomal acyl CoA oxidase 1 (acx1-2), we identified ACX1 as one of the main sources of ROS production and as partly the cause of the epinasty phenotype following the application of 2,4-D. Transcriptomic analyses of WT plants after treatment with 2,4-D revealed a ROS-related peroxisomal footprint in early plant responses, while other organelles, such as mitochondria and chloroplasts, are involved in later responses. Interestingly, a group of ACX1-dependent transcripts in plant responses to 2,4-D, previously associated with epinasty, is related to auxin biosynthesis, metabolism and signalling. We found that protein AUXIN SIGNALING F-BOX 3 (AFB3), a component of SCF (ASK-cullin-F-box) E3 ubiquitin ligase complexes, which functions as an auxin receptor and mediates Aux/IAA proteasomal degradation, acts downstream of ACX1 and is involved in the epinasty phenotype induced by 2,4-D. We also found that protein degradation associated with ubiquitin E3-RING and E3-SCF-FBOX in ACX1-dependent signalling in plant responses to 2,4-D is significantly regulated over longer treatment periods.

Nontarget-site resistance due to rapid physiological response in 2,4-D resistant Conyza sumatrensis: Reduced 2,4-D translocation and auxin-induced gene expression

Project description:We used RNAseq to quantify trascript expression from three populations of Conyza sumatrensis before and 5 hours after treatment with 2,4-D. This study investigates different responses between a 2,4-D resistant biotype compared to a 2,4-D sensitive biotype.

Whole genome expression in response to herbicidal levels of 2,4-D application

Project description:This experiment was annotated by TAIR (http://www.arabidopsis.org). In this experiment we examined whole genome response to herbicidal levels of 2,4-D application. Arabidopsis plants (14 days) grown in vitro on MS medium in petri dishes were flooded with 1 mL stock of 2,4-D to enable root uptake. Plants were treated with 1.0 mM 2,4-D for a period of 1 hour immediately after which RNA was extracted and used for the microarray based experiments. the goal of this study was to explore the herbicidal mode of action of auxinic herbicide 2,4-D.
