Microcystin-LR (0.02 μg/ml) in the hydroculture medium of Portulaca oleracea cv., became below the detection level (<0.0001 μg/ml) by HPLC analysis after 7 days. The toxicity of microcystin estimated with protein phosphatase inhibition assay, however, remained at 37% of the initial level, indicating that microcystin-LR was transformed by P. oleracea cv. into unknown compound(s) of lower toxicity.

Portulaca umbraticola, commonly known as "Eleven o'clock", is a popular ornamental plant in Brazil, but its potential as a non-conventional food source remains underexplored. Assessing its genetic and cytogenetic diversity is crucial for breeding and selecting optimal accessions. In this study, we analyzed the genetic diversity of P.

Identifying weed species at early-growth stages is critical for precision agriculture. Accurate classification at the species-level enables targeted control measures, significantly reducing pesticide use. This paper presents a dataset of RGB images captured with a Sony ILCE-6300L camera mounted on an unmanned aerial vehicle (UAV) flying at an altitude of 11 m above ground level.

Invasive weed species exhibit both advantages, such as the potential for allelochemicals in bioherbicide development, and risks, including their threat to crop production. Therefore, this study aims to identify an allelochemical from , an invasive weed species. The dose-dependent effects of shoot and root extracts (SSE, SRE) on the signaling in the forage crop and germination in various weed species (, , , , and ) were evaluated.

Purslane is a plant with high nutritional content that is mainly produced in the central part of Mexico. The nutritional content of purslane depends on various factors such as climatic and soil conditions, phenology, and fertilization. This article describes the H NMR metabolomics profiling of purslane in relation to fertilization at two harvest stages: C and C (27 and 42 days after emergence).
