Environmental Research, Journal Year: 2024, Volume and Issue: 252, P. 118839 - 118839

Published: April 1, 2024

Weeds pose multifaceted challenges in rice cultivation, leading to substantial economic losses through reduced yield and poor grain quality. Harnessing the natural genetic diversity germplasm collections becomes crucial for identifying novel herbicide resistance loci crops. A comprehensive analysis was conducted on 475 accessions from KRICE depository, assessing their response TFT (Tefuryltrione) probing underlying HIS1 (HPPD INHIBITOR SENSITIVE 1) genotypic variations. The gene, responsible detoxifying benzobicyclon (BBC) imparting broad-spectrum resistance, holds significant promise breeding. This study explores landscape of within Korean (KRICE), aiming unveil variations, haplotype diversity, evolutionary relationships across diverse ecotypes. indica ecotype showed highest nucleotide while wild temperate japonica groups exhibited low hinting at selective sweeps possible population expansion. Negative Tajima's D values indicate an excess low-frequency mutations, potentially resulting sweeps. In contrast, with positive values, admixture indica, aus, suggest balancing selection. Furthermore, uncovered 42 distinct haplotypes KRICE, four shared between cultivated accessions, specific 34 types. Phenotypic assessments these revealed that three haplotypes, viz., Hap_1 (predominant japonica), Hap_2 indica), Hap_3 (specific displayed differences aus-specific Hap_4 indica-specific Hap_5. offers insights into pressures, ecotype-specific responses, ultimately paving way developing HPPD-inhibiting herbicide-resistant cultivars.

Glyphosate residue in honey and impacts on Africanized bee hives under field conditions

Dataset Reports, Journal Year: 2023, Volume and Issue: 1(1)

Published: Jan. 27, 2023

Honey and other bee products may contain residues of different substances, including pesticides, which is considered a public health problem. In addition, they characterize risks to the Apis mellifera, have been showing an increasing decline in their populations. There are many protocols for identifying pesticides which, general, complex matrices whose results routine investigations control laboratories rarely disclosed. this sense, objective present study was determine presence glyphosate its metabolite aminomethylphosphonic acid (AMPA) honey, as well effect on strength hive A. mellifera. Samples were collected from hives experimentally exposed food containing sublethal dose Roundup® conducted by hydrophilic interaction liquid chromatography coupled tandem mass spectrometry (HILIC-MS/MS). The AMPA content lower than method’s detection limit honey samples that received herbicide. It possible quantify one week after last artificial feeding (R1 8.45 ± 1.09 µg g−1; R2 8.15 2.14 R3 23.90 2.95 g−1). sample fed more four weeks, concentrations (3.12 0.89 g−1) with no AMPA. From analysis hives, we observed decrease population adult individuals brood area, absence queen, construction royal cells workers treatment comparison group, remained queen size, high population, stock. Although present, did not undergo degradation during evaluated period. Thus, could infer feed be representing risk consumers’ economic damage beekeepers.

Use and Legislation of Glyphosate in Mexico: Healthcare, Healthy Environment and Drinking Water Access

Published: May 8, 2023

This paper analyzes the status of legal regulation use glyphosate in Mexico. To achieve this purpose, its has been debated constitutional obligations to human rights health, environment, and access drinking water. Several international instruments have reviewed give a brief balance among healthy, legal, environmental approaches, hence their impact Glyphosate is an agrochemical compound used as main substance formulation pesticides having low toxicological lever, it currently most widely herbicide worldwide. It well known that many organizations reported does not represent harm if properly and, concentration indicated regulations. However, inhibits enzymatic production which key factor aromatic amino acid biosynthesis needed for vegetation growth, negative effect on environment. In last years researchers suggested important risk health by indirect exposure, such water food polluted with residues, could develop diseases or conditions skin irritations, gastrointestinal conditions, endocrine hematological disrupters, etc. Mexico, there are reports about presence food, particularly 30% tortillas Mexico City presents residues. For reason, Mexican government decided eliminate crop fields 2024.

Stenotrophomonas pavanii MY01 induces phosphate precipitation of Cu(II) and Zn(II) by degrading glyphosate: performance, pathway and possible genes involved

Frontiers in Microbiology, Journal Year: 2024, Volume and Issue: 15

Published: Oct. 23, 2024

Microbial bioremediation is an advanced technique for removing herbicides and heavy metals from agricultural soil. In this study, the strain Stenotrophomonas pavanii MY01 was used its ability to degrade glyphosate, a phosphorus-containing organic compound, producing PO 4 3− as byproduct. known form stable precipitates with metals, indicating that could potentially remove by degrading glyphosate. Therefore, present experiment induced phosphate precipitation Cu(II) (Hereinafter referred Cu 2+ ) Zn(II) Zn glyphosate MY01. Meanwhile, whole genome of mined degradation mechanism metal removal mechanism. The results study showed degraded best at 34°C, pH = 7.7, inoculum 0.7%, reaching 72.98% within 3d. highest in test 75.95 68.54%, respectively. A comparison MY01’s genes protein sequences GE000474 GE002603 had strong similarity oxidoreductase C-P lyase. This suggests these may be key strain’s GE001435 sequence appears related pathway, which enable excretion into environment, where it forms coordination complexes metals.
