“…Within the haustorium, searching hyphae cells differentiate from the cortex, elongate and invade host tissue, giving rise to xylem vessel cells that connect to the host's xylem vessels, thus establishing parasitism (Kaga et al, 2020). Extensive research has been conducted on the different aspects of this ingenious parasitic strategy, including circumnutation and the coiling movements of Cuscuta shoots (Johnson et al, 2016; Lane & Kasperbauer, 1965), the development and morphology of haustoria (Birschwilks et al, 2007; Dawson et al, 1994; Hong et al, 2011; Kaga et al, 2020; Narukawa et al, 2021) and gene expression profiles during parasitism (Pan et al, 2022; Yokoyama et al, 2022).…”

Seedlings of the parasitic plant genus Cuscuta (dodder) locate hosts by circumnutation, coil around the host near soil level and form a haustorium, establishing a primary parasitism beneath the canopy. Mature shoots elongating from the parasitic region parasitize other hosts on the upper surfaces of their canopy. Although parasitism by dodder is stimulated by blue and far‐red light, and inhibited by red light, the responses to light signals during the developmental stages are not comprehensively understood. Therefore, we compared the effects of different types of light on both circumnutation and parasitism by germinating seedlings and mature shoots of Cuscuta campestris. Seedlings established parasitism under blue and far‐red light, but not under red light, as has been reported repeatedly. By contrast, mature shoots exhibited coiling around the host and haustoria formation even under a red light as well as under blue and far‐red light. These findings indicate that C. campestris modified its response to red light during the transition from young seedlings to mature shoots, facilitating parasitism. Light quality did not affect the circumnutation of either seedlings or mature shoots, indicating that circumnutation and the coiling movement that leads to parasitism were regulated by different environmental signals.

Background Research on the parasitic plant genus Cuscuta has flourished since the genomes of several of its species were published. Most of the research revolves around the iconic infection organ that secures the parasite’s sustenance: the haustorium. The interest in understanding the structure-function-regulation relationship of the haustorium is based as much on the wish to find ways to keep the parasite under control as on the opportunities it offers to shed light on various open questions in plant biology. Scope The review will briefly introduce parasitism among plants, using the genus Cuscuta as main example, before presenting its haustorium alongside the terminology that is used to describe its architecture. Possible evolutionary origins of this parasitic organ are presented. The haustorium is then being followed from its initiation to maturity under contemplation of the molecular landscape that accompanies the morphological changes and in the light of the challenges it must overcome before gaining access to the vascular cells of its hosts. The fact that Cuscuta has an unusually broad host range stresses how efficient its infection strategy is. Therefore, special consideration will be given in the final chapter to a comparison with the process of grafting, being the only other type of tissue connection that involves interspecific vascular continuity. Conclusions Studies on Cuscuta haustoriogenesis have revealed many molecular details that explain its success. They have also unearthed some mysteries, that wait to be solved. With a better understanding of the complexity of the infection with its combination of universal as well as host-specific elements that allow Cuscuta to parasitize on a wide range of host plant species, we may be many steps closer to not only containing the parasite better but also exploiting its tricks where they can serve us in the quest of producing more and better food and fodder.
