Commercial herbicides exhibit many different mechanisms of action. Several enzymes involved in biosynthesis of amino acids are sites of action for herbicides. A large number of different herbicide classes inhibit photosynthesis by binding to the quinone-binding protein, D-1, to prevent photosynthetic electron transfer. Several different types of herbicides apparently cause accumulation of photo...

Herbicide-resistant Palmer amaranth is a widespread issue in row-crop production in the Midsouthern US. Palmer amaranth is commonly found on roadside habitats in this region, but little is known on the degree of herbicide resistance in these populations. Herbicide resistance in roadside Palmer amaranth populations can represent the spread of an adaptive trait across a selective landscape. A lar...

Parietochloris incisa is an oleaginous fresh water green microalga that accumulates an unusually high content of the valuable long-chain polyunsaturated fatty acid (LC-PUFA) arachidonic acid within triacylglycerols in cytoplasmic lipid bodies. Here, we describe cloning and mutagenesis of the P. incisa acetohydroxyacid synthase (PiAHAS) gene for use as an herbicide resistance selection marker fo...

INTRODUCTION Pesticide poisoning is an important public health problem worldwide. The study aimed to determine the risk of all-cause and cause-specific inpatient mortality and to identify prognostic factors for inpatient mortality associated with unintentional insecticide and herbicide pesticide poisonings. METHODS We performed a retrospective cohort study of 3,986 inpatients recruited at hos...

Herbicide tolerance in crops and weeds is considered to be monotrophic, i.e. determined by the relative susceptibility of the physiological process targeted and the plant's ability to metabolise and detoxify the agrochemical. A growing body of evidence now suggests that endophytes, microbes that inhabit plant tissues and provide a range of growth, health and defence enhancements, can contribute...

TiO2 nanoparticles have emerged as a great photocatalyst to degrade organic contaminants in water; however, the dispersed water could be difficult recovered and potentially become contaminant. Herbicide like 2,4-dichlorophenoxyacetic acid (2,4-D) used agriculture usually ends up with large fraction remaining sediment, which may cause potential risk human health ecosystem. This study proposes gr...

Surfactants are often added to herbicidal formulations improve the delivery of herbicide into plants. In this study a new formulation was formed based on clopyralid with 0.01% gemini surfactant hexanediyl-1,6-bis(dimethylcetylammonium bromide) (16-6-16) as an adjuvant. The increase in efficiency associated formation supramolecular surfactant–herbicide complex (SMC), which has improved wetting p...

Culture conditions were developed that induce Arabidopsis thaliana (L.) Heynh. root cuttings to regenerate shoots rapidly and at 100% efficiency. The shoots produce viable seeds in vitro or after rooting in soil. A transformation procedure for Arabidopsis root explants based on kanamycin selection was established. By using this regeneration procedure and an Agrobacterium tumor-inducing Ti plasm...
