“…After proper attachment to the host's vascular system (xylem and phloem) through the haustoria [2], the parasite functions as an active sink, redirecting solutes away from autotrophic sink tissues. Due to this parasitism, C. campestris is considered to be among the most destructive agricultural weeds, significantly reducing the yield and quality of the crops' products [3][4][5][6]. It attacks many broad-leaf plants, the most sensitive of which include alfalfa, carrot, tomato, sugar beet, onion, potato and several ornamental plants [3].…”

“…Despite knowledge accumulated on the parasite's lifecycle, mode of action and agricultural damage, our knowledge about the metabolites absorbed by the parasite and how the host affects its primary metabolic profiling is still mostly unknown [6]. Moreover, there is debate in the literature as to whether most of the metabolites found in holoparasites such as C. campestris are taken from the host, or whether the parasite produces most of its metabolites on its own, relying primarily on the sugars transported from its hosts.…”

“…In addition, several reports suggest that holoparasitic plants can self-regulate their own metabolites since their metabolic profiles differ significantly from their hosts [8,[12][13][14]. Still, numerous questions remain unanswered regarding the independence of the parasite from the metabolisms of its host [6].…”

Cuscuta campestris (dodder) is a stem holoparasitic plant without leaves or roots that parasitizes various types of host plants and causes damage to certain crops worldwide. This study aimed at gaining more knowledge about the effect of the hosts on the parasite’s levels of primary metabolites. To this end, metabolic profiling analyses were performed on the parasite’s three main organs, haustoria, stem and flowers, which developed on three hosts, Heliotropium hirsutissimum, Polygonum equisetiforme and Amaranthus viridis. The results showed significant differences in the metabolic profiles of C. campestris that developed on the different hosts, suggesting that the parasites rely highly on the host’s metabolites. However, changes in the metabolites’ contents between the organs that developed on the same host suggest that the parasite can also self-regulate its metabolites. Flowers, for example, have significantly higher levels of most of the amino acids and sugar acids, while haustoria and stem have higher levels of several sugars and polyols. Determination of total soluble proteins and phenolic compounds showed that the same pattern is detected in the organs unrelated to the hosts. This study contributes to our knowledge about the metabolic behavior of this parasite.

“…This death of roots is known as haustoria. Dodders are cosmopolitan obligate parasites that are purely weedy and causing damage to host plant species (Lanini & Kogan, 2005;Flores-Sánchez & Garza-Ortiz, 2019). The authors add that they obtain all of their growth requirements (water, minerals, and carbohydrates) by attaching to host plants.…”

Dodders are cosmopolitan generalist holoparasites that forage on a community of plant species ranging from shrubs, trees and herbaceous. In this study, we employ mixed method research design that involved use of questionnaires and dodder host sampling matrix. Host identification and naming was carried out by ecological Android PlantNet Plant App version 3.0.5. Respondents sample size was determined by Krejcie and Morgan sampling formula. Results show that dodder was fast spreading through spatial retrospective satellite Landsat imagery analysis. Dodder was known by the majority of respondents (97.1%) where the exploratory analysis score shows that respondents' constituency of residence influenced their understanding of dodder (F(5, 361) = 5.329, P = 0.000). The mode of parasitism between dodder & the hosts varied as some ornamental trees, shrubs and herbaceous plants were either affected moderately or extremely. The study recommends use of biotechnological dodder control approaches through transgenic plants biotechnology and plant breeding to develop resistance towards dodder plant parasites.

“…At least 24 species have had their secondary metabolites described in the literature (Ahmad et al 2017; Flores-Sánchez and Garza-Ortiz, 2019). These constituents have been associated with several pharmacological activities described from various extracts, including hepatoprotective, antiosteoporotic, antioxidant, antimicrobial, anti-aging, antiproliferative, antidiabetic, renoprotective, and effects on the reproductive system (Donnapee et al 2014;Ahmad et al 2017;Flores-Sánchez and Garza-Ortiz 2019). In addition, the majority of Cuscuta species are numerous and act as keystone organisms in their natural ecosystems, and therefore require conservation measures as some are presumed extinct (Press and Phoenix 2005;Costea and Stefanovic 2009).…”

The genus Cuscuta L. (Convolvulaceae) are holoparasitic plants with cosmopolitan distributions, and they are usually difficult to identify. Based on several new field collections, we present three new floristic records from this genus in Central-West Brazil. Cuscuta platyloba Progel and Cuscuta partita Choisy are cited for the first time from Mato Grosso do Sul state, while Cuscuta xanthochortos var. carinata Mart., which was previously only known from southern Brazil, is also shown to be present in the Central-West region of the country. An identification key of Cuscuta species from Mato Grosso do Sul is also provided.
