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...

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...

Natural hybridization frequently promotes gene introgression among closely related species in sympatric populations, producing complex patterns of morphological variation. Therefore, a detailed understanding of the dynamics of interspecific gene flow and its morphological patterns is of widespread...

The genus Tithonia is an important source of diverse natural products, particularly sesquiterpene lactones, diterpenes, and flavonoids. The collected information in this review attempts to summarize the recent developments in the ethnobotany, biological activities, and secondary metabolite...

The evolutionary genetics of invasive species has been relatively unexplored. Hybridization of invasive populations can generate novel genotypes, stimulating the colonization of new environments. A sunflower complex occurring in Mexico formed by two native invasive species, Tithonia tubaeformis and ...

Vegetable production is an economically viable enterprise in Zimbabwe. The most commonly grown leafy vegetable is Brassica napus (rape). The productivity of this vegetable is affected by poor soil fertility, with nitrogen being the most limiting nutrient. An experiment was carried out to evaluate...

Mexican sunflower is a native species of North and Central America that was introduced into China early last century, but it has widely naturalized and become a harmful invasive plant in tropical and subtropical regions in South China. Inter-simple sequence repeat (ISSR) markers were employed to...
