Description

Quinclorac Methyl Ester, also known as the methyl ester of quinclorac, is a chemical compound that belongs to the class of quinazolinone herbicides. It is a white crystalline solid with a molecular formula of C12H13ClN2O2. QUINCLORAC-METHYL ESTER is known for its effective weed control properties and is widely used in agriculture.
Used in Agricultural Industry:
Quinclorac Methyl Ester is used as a herbicide for controlling a broad spectrum of grass and broadleaf weeds in various crops such as corn, soybean, cotton, and rice. It works by inhibiting the enzyme phosphoenolpyruvate carboxylase (PEPC), which is essential for the growth and development of weeds. This results in the cessation of photosynthesis and ultimately leads to the death of the weed.
Additionally, Quinclorac Methyl Ester is used in the preparation of agricultural products, specifically herbicides, to enhance their effectiveness in controlling unwanted vegetation. Its application in this industry helps improve crop yield and quality by reducing competition for resources and preventing the spread of weed-borne diseases.

Identifying and sequencing a Mycobacterium sp. strain F4 as a potential bioremediation agent for quinclorac

Quinclorac is a widely used herbicide in rice filed. Unfortunately, quinclorac residues are phytotoxic to many crops/vegetables. The degradation of quinclorac in nature is very slow. On the other hand, degradation of quinclorac using bacteria can be an effective and efficient method to reduce its contamination. In this study, we isolated a quinclorac bioremediation bacterium strain F4 from quinclorac contaminated soils. Based on morphological characteristics and 16S rRNA gene sequence analysis, we identified strain F4 as Mycobacterium sp. We investigated the effects of temperature, pH, inoculation size and initial quinclorac concentration on growth and degrading efficiency of F4 and determined the optimal quinclorac degrading condition of F4. Under optimal degrading conditions, F4 degraded 97.38% of quinclorac from an initial concentration of 50 mg/L in seven days. Our indoor pot experiment demonstrated that the degradation products were non-phytotoxic to tobacco. After analyzing the quinclorac degradation products of F4, we proposed that F4 could employ two pathways to degrade quinclorac: one is through methylation, the other is through dechlorination. Furthermore, we reconstructed the whole genome of F4 through single molecular sequencing and de novo assembly. We identified 77 methyltransferases and eight dehalogenases in the F4 genome to support our hypothesized degradation path.
