Tithonia diversifolia is an invasive weed commonly found in tropical ecosystems. In this work, we investigate the influence of different abiotic environmental factors on the plant's metabolite profile by multivariate statistical analyses of spectral data deduced by UHPLC-DAD-ESI-HRMS and NMR...

Herbivory is a main source of plant damage and injured plants might present decrements in nutrients, delayed growth and low reproductive outputs. Therefore, herbivory can be considered a stressful agent to plants. In this study, we investigated short-term changes in stress and nutrient levels of...

Premise of the study: Tithonia diversifolia (Asteraceae) is an invasive plant species that can outcompete natives and thus poses a great threat to biodiversity in introduced areas. Here, expressed sequence tag-simple sequence repeat (EST-SSR) markers were developed and characterized. Methods and...

The introduced shrub flora in Rwanda was analyzed and the risk of invasion was assessed based on the species' purposes of introduction. The results showed that more than half of invasive alien shrubs in Rwanda were introduced as ornamentals. They include Agave americana L., Bryophyllum proliferum...

Tithonia diversifolia, well-known as Mexican sunflower, is an invasive shrub growing in tropical areas of South America, Asia and Africa where it is used as a traditional medicine, ornamental plant and green biomass to improve soil fertility. Given the traditional uses in the treatment of skin...

Plant biowaste of alien species represents a potential resource for compost production. This study investigated the seed and seedling responses of maize and pea to composts generated from the biowaste of four invasive species in eThekwini, South Africa: Acacia podalyriifolia, Hedychium gardnerianum...

The components of humic and fulvic acid of organic matter determine the effectiveness of herbicide adsorption in soil. The persistence of atrazine and oxyfluorfen in soils added with invasive weeds organic matter (Tithonia diversifolia and Chromolena odorata) was determined. The soils were treated...

Through DNA extraction, PCR amplification and DNA sequencing, the conservative 18S rRNA sequences of phyllosphere fungi from leaves of Tithonia rotundifolia and Desmodium spicatum were analyzed. The results showed that both plant species shared some common fungi species from the subclass of...

By using 95% ethyl alcohol, stems and leaves extract from Eupatorium adenophorum, Mikania micrantha, Bidens pilosa, Tithonia diversifolfa, Oxalis corniculata were extracted. Every kind of extract was diluted to 3 concentrations of 1, 5 and 10 times. The bioassays of contact toxicity on M. rosivorum ...
