“…Haustoria formation is initiated by the mechanical stimulus resulting from the contact between parasite and host stems (Tada et al 1996;Haidar et al 1997;Ihl and Wiese 2000). Furthermore, phytochromes (Tada et al 1996;Furuhashi et al 1997;Haidar et al 1997) and diVerent phytohormones, in particular auxin and cytokinin, were found to be involved in haustoria development (Paliyath et al 1978;Rajagopal et al 1988;LöZer et al 1999).…”

Arabidopsis thaliana and Cuscuta spec. represent a compatible host-parasite combination. Cuscuta produces a haustorium that penetrates the host tissue. In early stages of development the searching hyphae on the tip of the haustorial cone are connected to the host tissue by interspecific plasmodesmata. Ten days after infection, translocation of the fluorescent dyes, Texas Red (TR) and 5,6-carboxyfluorescein (CF), demonstrates the existence of a continuous connection between xylem and phloem of the host and parasite. Cuscuta becomes the dominant sink in this host-parasite system. Transgenic Arabidopsis plants expressing genes encoding the green fluorescent protein (GFP; 27 kDa) or a GFP-ubiquitin fusion (36 kDa), respectively, under the companion cell (CC)-specific AtSUC2 promoter were used to monitor the transfer of these proteins from the host sieve elements to those of Cuscuta. Although GFP is transferred unimpedly to the parasite, the GFP-ubiquitin fusion could not be detected in Cuscuta. A translocation of the GFP-ubiquitin fusion protein was found to be restricted to the phloem of the host, although a functional symplastic pathway exists between the host and parasite, as demonstrated by the transport of CF. These results indicate a peripheral size exclusion limit (SEL) between 27 and 36 kDa for the symplastic connections between host and Cuscuta sieve elements. Forty-six accessions of A. thaliana covering the entire range of its genetic diversity, as well as Arabidopsis halleri, were found to be susceptible towards Cuscuta reflexa.

“…Blue light at photon fluxes lower than 1 µmol m -2 s -1 promoted neither coiling nor initiation of prehaustoria (Haidar et al 1997). The effect of far-red light was completely reversed by a red light treatment (Tada et al 1996;Furuhashi et al 1997;Haidar et al 1997). The action spectrum for induction of prehaustoria had a pronounced peak near 740 nm and a small peak at 420 nm, while reversal of prehaustoria induction had major a peak at 660 nm and a minor peak at 380 nm (Furuhashi et al 1997;Haidar et al 1997).…”

“…However, twining around the host does not necessarily lead to initiation of prehaustoria (Furuhashi et al 1995). The coiling action and the initiation of prehaustoria are suppressed under darkness, white fluorescent and red light conditions, and they are induced by far-red and/or blue light and tactile (mechanical, thigmotropic) stimuli (Zimmerman 1962;Lane and Kasperbauer 1965;Furuhashi et al 1995Furuhashi et al , 1997Tada et al 1996). This would explain why seedlings of C. campestris that emerged under an established alfalfa crop had their attachment to host reduced by 90% (Dawson 1966).…”

“…Chryptochromes interact synergistically with the Pr (red light absorbing) form of phytochrome, and antagonistically with Pfr form in mediating initiation and coiling of prehaustoria (Haidar 2003). Phytochrome B (Furuhashi et al 1997) or phytochrome A (Haidar et al 1998) may be involved. Tactile stimulation determined twining and prehaustoria initiation in blue and a mixture of blue/far-red light, but not in darkness or fluorescent white light (Tada et al 1996;Haidar et al 1997).…”

“…), while exposure to red light (620–700 nm) in the absence of other wavelengths inhibits twining (Lane & Kasperbauer ) and haustoria production (Furuhashi, Kanno & Morita ; Furuhashi et al . ). However, simultaneous exposure to red and far‐red light can have variable effects depending on the specific treatment.…”

Science, ETH Z€ urich, Z€ urich 8092, Switzerland Summary 1. Parasitic plants in the genus Cuscuta (dodders) make their living by extracting resources from other plants. While relatively few dodder species are agricultural pests, those that are can be challenging to control, in part due to their intimate physical and physiological association with host plants. Consequently, dodders remain pervasive and economically damaging pests in a variety of crop systems. The development of improved management strategies would be facilitated by greater understanding of the ecological and environmental factors that influence the establishment and perpetuation of dodder infestations. 2. Light cues play an important role in dodder host location and attachment. To better understand the influence of light conditions on parasite ecology, and potential implications for management, we examined how manipulating the ratio of red to far-red wavelengths (R:FR), via both passive filtering of natural sunlight and active spectral manipulation using LEDs, affects host location and host attachment by two dodder species (C. campestris on tomato hosts and C. gronovii on jewelweed). 3. For both host-parasite combinations, host location and subsequent attachment by dodder parasites was dramatically reduced in high-R:FR environments compared to control conditions (with R:FR characteristic of sunlight) and low-R:FR conditions. Circumnutation by dodder seedlings was also significantly faster under high R:FR. 4. We observed short-term effects of high R:FR on the height and dry mass of tomato host plants (immediately following 7-day exposure), as well as changes in tomato volatile emissions. However, preliminary investigation of long-term effects on host plants suggests that short-term exposure to high R:FR (i.e. during the critical period when dodder seedlings emerge and attach to hosts) has little or no effect on host plant size or fruit yield at the time of harvest. 5. Synthesis and applications. Our findings suggest that spectral manipulation during the early stages of crop plant growth (e.g. via light-filtering row covers) may have significant potential to augment existing methods for managing or preventing dodder infestations in agricultural crops. We discuss potential obstacles to the realization of its potential, as well as next steps towards the development and optimization of spectral manipulation methods for use in agroecosystems.
