“…The tomato species ( Lycopersicum esculentum ), belonging to the Solanaceae family, has been used in order to determine the phytotoxic activity of various plant extracts [ 53 , 54 , 55 ] or antibiotics [ 56 ], being considered an appropriate species due to its sensitivity to toxic substances, availability, and good germinating rate [ 46 , 57 ].…”

Ailanthus altissima, an invasive plant species, exhibits pharmacological properties, but also some allergic effects on humans. This study aimed to evaluate the potential toxicity of A. altissima leaves, using a complex approach towards different organisms. The ecotoxic impact of a crude extract was investigated on seeds germination and brine shrimp lethality. Cytotoxicity was studied in vitro using non-target (haemolysis, liposomal model, fibroblast), and target (cancer cells) assays. Leaf extract at 1000 µg/mL significantly inhibited wheat and tomato germination, while no significant effects were found on parsley germination. A slight stimulatory effect on wheat and tomato germination was found at 125 µg/mL. In a brine shrimp-test, the extract showed a low toxicity at 24 h post-exposure (LC50 = 951.04 ± 28.26 μg/mL), the toxic effects increasing with the exposure time and extract concentration. Leaf extract caused low hematotoxicity. The extract was biocompatible with human gingival fibroblasts. No anti-proliferative effect was found within the concentration range of 10–500 µg/mL on malignant melanoma (MeWo) and hepatocellular carcinoma (HepG2). In a liposomal model-test, the extract proved to possess low capability to alter the eukaryotic cell-mimicking membranes within the tested concentration range. Given the low to moderate toxicity on tested organisms/cells, the A. altissima autumn leaves may find useful applications.

“…Bioassays on seed germination and seedling growth of the five bio-indicator species were carried out to ascertain the phytotoxic potential of different parts of the purple amomum, including the leaf, pseudo-stem, rhizome and root, and seed [8,34,35,[39][40][41][42][43][44][45].…”

“…The radicle emergence of the seeds was recorded as germinated [46]. Three germination parameters, including germination percentage (GP), mean germination time (MGT), and germination rate index (GRI), were determined according to the formulas mentioned in previous studies [8,34,35,[39][40][41][42][43][44][45][46][47][48]. On the 12th day, radicle length, hypocotyl length, and the fresh weights of the tested seedlings were also measured.…”

The ginger family member purple amomum (Amomum longiligulare T.L. Wu) is an important medicinal plant in Vietnam. Although there have been studies on the chemical composition of essential oils and extracts of purple amomum, as well as their antibacterial, antifungal, activating macrophages, and immune enhancement effects, there is still a lack of evaluation of the phytotoxicity of this plant. In this study, the total content of phenolic (TPC) and flavonoid (TFC) in extracts of leaf, seed, pseudo-stem, rhizome, and root from purple amomum and the phytotoxic effect of these extracts against five test plant species, including four dicotyledonous: camelina (Camelina sativa Crantz), quinoa (Chenopodium quinoa Willd.), cabbage (Brassica oleracea var. capitata L.), tomato (Solanum lycopersicum L. cv. Dubrava), and one monocotyledonous: onion (Allium cepa L. cv. Stuttgarter risen), were investigated. Results showed that the seed and leaf extracts had higher total phenolic and flavonoid contents than the other two extracts (highest TPC value: 4.30 ± 0.03 mg GAE/mg dry weight of seed powder; highest TFC value: 1.32 ± 0.07 mg QE/mg dry weight of leaf powder). Furthermore, it was observed that the extracts of purple amomum inhibited seed germination and the growth of seedlings of all test plant species with different inhibition values. The general trend in all treatments showed that, when increasing the concentration of extracts from 0.10–0.20 mg/mL, the ability to inhibit seed germination, hypocotyl length, radicle length, fresh weight, and dry weight increased. Seed extract at a concentration of 0.20 mg/mL in most treatments showed the highest percentage inhibition of seed germination and growth of seedlings of the tested species. Onion was the most sensitive to purple amomum extracts among the five species tested. Based on these results, we conclude that extracts of different parts of the purple amomum exhibited phytotoxicity for the tested species. Further evaluation of the phytotoxic potential of the extracts on weed species and under field conditions is also recommended for the purpose of developing bio-herbicides for future weed management that are less toxic to the environment and human health.

“…In México, several studies have been focused on the control of plant pests and diseases; Salmea scandens extracts to inhibit the growth of Fusarium oxysporum and Alternaria solani of tomato (Salas-Marina et al, 2021), extracts of Larrea tridentata and Hymenoclea monogyra control F. oxysporum f. sp. basilici in basil (Holguín-Peña et al, 2021), extracts of Baccharis salicifolia and Lepidium virginicum as herbicides on tomato cultivation (Miranda-Arámbula et al, 2021), the acaricide activity of Lippia berlandieri and Azadirachta indica (Ruiz-Jimenez et al, 2021), among others.…”

Background: The COVID-19 pandemic evidenced the fragility of the agri-food sector by affecting the food supply chains which directly depend on the health of its main actors. In this context, countries need to rethink the agricultural production models, considering environmental and human health as priorities to achieve food safety. Aim: Systematically review the state of the art regarding the role of agricultural genetic resources as a source of resilience in the face of events such as the present pandemic as a point of reflection for the identification of opportunities for the restructuring of regional agriculture sensitive to nutrition for health. Methodology: Exhaustive search and analysis of documentary information regarding the effects of COVID-19 on the agri-food sector and the role of agricultural genetic resources in the current pandemic were conducted. Then, through an analysis of the occurrence and association of the main terms addressed in the literature considered, the thematic axes were drawn to address the central discussion of the systematic review. Results: Terms co-occurrence analysis corroborated the relevance and pertinence of the topic addressed. Additionally, the importance of the conservation of agricultural genetic resources and implementation of sustainable agriculture models, as a source of resilience to pandemics, was visualized. The discussion addressed the impact of the pandemic on the Mexican agri-food sector and the restructuring of post-COVID-19 agriculture through the nation and nutrition-sensitive agriculture for health approaches. Implications: The exhaustive analysis of the relationship COVID-19-agricultural genetic resources-health in Mexico highlights the need for the generation of agricultural policies and the increase in multidisciplinary research that favors biodiversity as a source of sustainability, productivity, and health for agroecosystems and the welfare of humanity. Conclusions: A fatalistic scenario for humanity seems to be dissipating in the face of the possibilities of rethinking the economic, social, and agricultural systems from the approaches of the nation and nutrition-sensitive agriculture for health, where, through the responsible use of agricultural resources it is possible to rebuild an agri-food production system with a tendency to resilience to events such as the current pandemic caused by the COVID-19 disease.
