“…The genus Cuscuta consists of ;150 species and is among the most successful and devastating plant parasites, causing serious damage by suppressing the growth of its host and, in some cases, leading to host death. Its members exhibit a broad host range, parasitizing both domesticated and nondomesticated plants (Gaertner, 1950;Kuijt, 1969;Malik and Singh, 1979;Dawson et al, 1994). Dodder seeds germinate and form a thread-like stem.…”

Interspecific RNA Interference of SHOOT MERISTEMLESS-Like Disrupts Cuscuta pentagona Plant Parasitism

Infection of crop species by parasitic plants is a major agricultural hindrance resulting in substantial crop losses worldwide. Parasitic plants establish vascular connections with the host plant via structures termed haustoria, which allow acquisition of water and nutrients, often to the detriment of the infected host. Despite the agricultural impact of parasitic plants, the molecular and developmental processes by which host/parasitic interactions are established are not well understood. Here, we examine the development and subsequent establishment of haustorial connections by the parasite dodder (Cuscuta pentagona) on tobacco (Nicotiana tabacum) plants. Formation of haustoria in dodder is accompanied by upregulation of dodder KNOTTED-like homeobox transcription factors, including SHOOT MERISTEMLESS-like (STM). We demonstrate interspecific silencing of a STM gene in dodder driven by a vascular-specific promoter in transgenic host plants and find that this silencing disrupts dodder growth. The reduced efficacy of dodder infection on STM RNA interference transgenics results from defects in haustorial connection, development, and establishment. Identification of transgene-specific small RNAs in the parasite, coupled with reduced parasite fecundity and increased growth of the infected host, demonstrates the efficacy of interspecific small RNA-mediated silencing of parasite genes. This technology has the potential to be an effective method of biological control of plant parasite infection.

“…Field dodder is able to cause the most intensive damage in newly-formed perennial legume (alfalfa or clover) crops, which are the most frequent targets of dodder parasitism (Dawson et al, 1994). Damage done in these crops consists mainly of reduced fresh biomass yield, which may be upwards of 50%, and significantly reduced seed production by seed alfalfa (Cudney et al, 1992).…”

“…Dawson (1989) reported a yield loss of 57% in an alfalfa crop artificially infested with C. campestris in Prosser, Washington (USA) over a period of two years. Two years later, potato was sawn in the same location and the crop was totally destroyed by field dodder (Dawson et al, 1994). Mishra (2009) reported some 60% yield reduction in alfalfa infested with C. campestris.…”

“…Crop rotation is an important preventive measure even though it may be difficult to find an adequate replacement for some crops and so avoid dodder parasitism in that new crop (Parker, 1991). Cereals are considered suitable rotation crops as they have not been observed to host Cuscuta species (Dawson, 1987;Dawson et al, 1994).…”

Field dodder - how to control it?

SUMMARYBroad geographic distribution and spectrum of hosts make field dodder, Cuscuta campestris, one of the most widespread and most harmful pests among flowering parasitic plants. Field dodder may become a problem in vegetable nurseries (e.g. tomato, sweet pepper and cabbage) or in potato or some other crop grown in plastic greenhouses. However, the most devastating damage comes from field dodder outbreaks in newly-established perennial legume crops (alfalfa, clover, etc.), which are generally the preferred hosts of this parasitic flowering species. Apart from alfalfa and clover, an expansion of field dodder has been observed in recent years in sugar beet, too.Different measures are available for controlling field dodder, from preventive (pure seeding material, tolerant cultivars, etc.), to mechanical removal (mowing and hand weeding) to herbicide treatments. The most successful control of field dodder requires a systematic approach ensured through integrated protection, which contributes to a more effective control of parasitic flowering plants.

Cuscuta reflexa is a parasitic plant which belongs to family Convolvulaceae. It is commonly known as dodder plant, amarbel, akashabela. Traditionally it is called miracle plant. It is rootless, perennial, leafless climbing parasitic twining herb which takes food from host plant with help of special organ called haustorium. This review article will collect the detailed description of synonyms, vernacular name, habitat, botanical description, ethno-medicinal uses, properties, chemical constituents, pharmacological uses of Cuscuta reflexa from different classical Ayurvedic literature as well as modern research journals. This review article deals with Antihypertensive, Antidiabetic, Antioxidant, Hair growth promoting, Antimicrobial, Spasmolytic, Antitumor, Anti-arthritic, Nephroprotective, Antiviral, Anti-inflammatory, Antipyretic effect of Cuscuta reflexa. More researches should be done in this plant to explore its mode of action and uses.
