The Host-Haustorium Interface in Powdery Mildews
Australian Journal of Plant Physiology, 1989The powdery mildew fungi have proven to be a useful model system for studies of the host-parasite interface in biotrophic parasitism. Investigation of the interface has requrred the development of novel experimental approaches, for example the isolation of populations of haustoria in association with other interface components and the chemical and ...

EMBRYOLOGY AND DEVELOPMENT OF THE ENDOSPERM HAUSTORIUM OF ARCEUTHOBIUM DOUGLASII
American Journal of Botany, 1965Arceuthobium douglasii develops a dome‐like structure, the ovarian papilla, in which 2 megasporocytes are formed. The papilla is not a true ovule, for no integuments are formed, and it is forced aside by the developing endosperm. Megasporocytes are differentiated in the spring, but meiosis does not occur until the following spring. A tetrasporic embryo

Functional Structure of the Mature Haustorium
2013The morphology and functional anatomy of lateral and terminal haustoria are described in this chapter, with emphasis on the patterns of tissue connection with both the host and the parasite, while discussing the possible role of each tissue within the haustorium.

Haustorium Invasion into Host Tissues
2013The invasive phase of haustorium development starts when the young haustorium adheres to host roots by means of specialized attachment devices employing adhesive substances. A group of intrusive cells then enzymatically and mechanically penetrate host tissues.

Transcriptome analysis of mistletoe (Viscum album) haustorium development
Horticulture, Environment, and Biotechnology, 2014The haustorium is a specific organ for penetration of host tissue in parasitic plants. To better understand the molecular mechanisms of the establishment of host-parasite relationships using gene expression profiles, early stage haustorium germination from mature mistletoe seeds was examined. We have generated a cDNA library that is an excellent source

The Haustorium and the Life Cycles of Parasitic Orobanchaceae
2013The haustorium is a key organ of all parasitic plants. It penetrates host tissues and serves as the bridge facilitating the withdrawal of part or all of the parasite’s nutritional needs from the conductive systems of host plants. This chapter presents a general description of the haustorium and its functions, and the life cycles of obligate and ...

MODE OF ATTACHMENT, HAUSTORIUM STRUCTURE, AND HOSTS OF PEDICULARIS CANADENSIS
American Journal of Botany, 1963Piehl, Martin A. (Botanic Garden, Santa Barbara, Calif.) Mode of attachment, haustorium structure, and hosts of Pedicularis canadensis. Amer. Jour. Bot. 50(10): 978–985. Illus. 1963.—Although long known for European members of the genus, parasitism is documented for the first time for the North American Pedicularis canadensis (Scrophulariaceae) from ...
