“…Facultative parasites are typically generalist feeders with a broad host range. For example, the parasitic plant Triphysaria versicolor parasitizes a wide range of monocots and dicots, including Arabidopsis thaliana, Medicago truncatula, maize (Zea mays), and rice (Oryza sativa; Thurman, 1966;Estabrook and Yoder, 1998;Jamison and Yoder, 2001).…”

A Single-Electron Reducing Quinone Oxidoreductase Is Necessary to Induce Haustorium Development in the Root Parasitic Plant Triphysaria

Parasitic plants in the Orobanchaceae develop haustoria in response to contact with host roots or chemical haustoriainducing factors. Experiments in this manuscript test the hypothesis that quinolic-inducing factors activate haustorium development via a signal mechanism initiated by redox cycling between quinone and hydroquinone states. Two cDNAs were previously isolated from roots of the parasitic plant Triphysaria versicolor that encode distinct quinone oxidoreductases. QR1 encodes a single-electron reducing NADPH quinone oxidoreductase similar to z-crystallin. The QR2 enzyme catalyzes two electron reductions typical of xenobiotic detoxification. QR1 and QR2 transcripts are upregulated in a primary response to chemical-inducing factors, but only QR1 was upregulated in response to host roots. RNA interference technology was used to reduce QR1 and QR2 transcripts in Triphysaria roots that were evaluated for their ability to form haustoria. There was a significant decrease in haustorium development in roots silenced for QR1 but not in roots silenced for QR2. The infrequent QR1 transgenic roots that did develop haustoria had levels of QR1 similar to those of nontransgenic roots. These experiments implicate QR1 as one of the earliest genes on the haustorium signal transduction pathway, encoding a quinone oxidoreductase necessary for the redox bioactivation of haustorial inducing factors.

“…These include phenolic acids, flavonoids, and quinones (Estabrook and Yoder, 1998;Kim et al, 1998;Albrecht et al, 1999). The only HIF that has been identified directly so far from plant roots is 2,6-dimethoxy-pbenzoquinone (DMBQ; Chang and Lynn, 1986).…”

Haustorial Hairs Are Specialized Root Hairs That Support Parasitism in the Facultative Parasitic Plant Phtheirospermum japonicum

et al. 2015

A haustorium is the unique organ that invades host tissues and establishes vascular connections. Haustorium formation is a key event in parasitism, but its underlying molecular basis is largely unknown. Here, we use Phtheirospermum japonicum, a facultative root parasite in the Orobanchaceae, as a model parasitic plant. We performed a forward genetic screen to identify mutants with altered haustorial morphologies. The development of the haustorium in P. japonicum is induced by host-derived compounds such as 2,6-dimethoxy-p-benzoquinone. After receiving the signal, the parasite root starts to swell to develop a haustorium, and haustorial hairs proliferate to densely cover the haustorium surface. We isolated mutants that show defects in haustorial hair formation and named them haustorial hair defective (hhd) mutants. The hhd mutants are also defective in root hair formation, indicating that haustorial hair formation is controlled by the root hair development program. The internal structures of the haustoria in the hhd mutants are similar to those of the wild type, indicating that the haustorial hairs are not essential for host invasion. However, all the hhd mutants form fewer haustoria than the wild type upon infection of the host roots. The number of haustoria is restored when the host and parasite roots are forced to grow closely together, suggesting that the haustorial hairs play a role in stabilizing the host-parasite association. Thus, our study provides genetic evidence for the regulation and function of haustorial hairs in the parasitic plant.

“…Influx of P in roots colonized by this fungus can be three to five times higher than in non-mycorrhizal roots (Van Rhijn et al 1997;Kim et al 1997). In addition, as much as 20% of a plant's photosynthate can be released from the roots into the soil (Asmar and Gissel-Nielsen 1997;Estabrook and Yoder 1998). In tomato roots, N and P uptake as well as plant size increase by the interaction between phosphate-solubilizing bacteria and arbuscular mycorrhizae (Kim et al 1997).…”

Minerals accumulated during each stage of plant development are important, especially for the initial portion of subsequent stages of growth. For example, minerals acquired during seed ontogeny are largely responsible for the earliest stage of seedling growth. Without these minerals, seedling development would be arrested or impossible. Thus, even though the amount of minerals may be relatively small in the seed, their presence is absolutely essential. Similarly, although the mineral nutrient content of a seedling used as a transplant in establishing a crop in the field may seem rather minuscule, the importance to the initiation of development of the successive stage of growth is critical. Moreover, seedling-mineral content, plant performance and seed production can be improved by the selection of optimal cultural practices. This review examines acquisition, content and use of minerals in the various stages of plant development and growth as well as agricultural approaches to enhance mineral accumulation.Key words: Nutrient uptake, field crop establishment, seed mineral content, seed yield, crop growth.Liptay, A. et Arevalo, A. E. 2000. Accumulation, utilisation et transport des minéraux durant le cycle biologique des plantes. Mise au point bibliographique. Can. J. Plant Sci. 80: 29-38. Les minéraux absorbés à chaque stade de croissance de la plante sont importants, en particulier pour la portion initiale de chaque stade ultérieur. Ainsi par exemple, les minéraux absorbés durant l'ontogénie de la graine joueront un rôle déterminant dans les premiers de la croissance de la plantule. Sans eux, celles-ci seraient entravées ou impossibles. Donc même si les quantités absorbées dans la graine sont dans certains cas relativement petites, leur importance n'en demeure pas moins essentielle. De même, si la teneur en éléments nutritifs minéraux dans le jeune plant destiné à être repiqué au champ peut paraître infime, leur présence jouera un rôle critique dans l'initiation de chacun des stades de croissance successifs. D'autre part, il est possible, en adoptant les pratiques culturales optimales d'améliorer la teneur en minéraux du jeune plant et avec elle les performances de la plante et sa production semencière. La revue bibliographique porte sur l'acquisition, les concentrations et l'utilisation des minéraux aux divers stades de croissance et de différenciation, de même que sur les moyens agronomiques de stimuler cette accumulation. Mots clés:Absorption des éléments nutritifs, installation en pleine terre, teneur minérale de la graine, rendement semencier, croissance végétaleCrop production and seedling performance in the field are the result of an adequate supply, distribution and accumulation of minerals, especially during seed formation. For example, minerals are collected at each stage of plant development in preparation for futu...
