Haustorium initiation in the obligate parasitic plant Phelipanche ramosa involves a host-exudated cytokinin signal

open access: yesJournal of Experimental Botany, 2017
The heterotrophic lifestyle of parasitic plants relies on the development of the haustorium, a specific infectious organ required for attachment to host roots.

Molecular Processes of Dodder Haustorium Formation on Host Plant under Low Red/Far Red (R/FR) Irradiation

open access: yesInternational Journal of Molecular Sciences, 2022
Low R/FR irradiation can promote dodder haustorium formation on the host plant; however, the mechanisms underlying the process are still unknown. In this study, we compared the transcriptomic data during the formation of haustorium of Cuscuta chinensis ...

Induction of Haustorium Development by Sphaeropsidones in Radicles of the Parasitic WeedsStrigaandOrobanche. A Structure–Activity Relationship Study

open access: yesJournal of Agricultural and Food Chemistry, 2016
Crop attack by parasitic weeds such as Striga and Orobanche occurs through developmental processes triggered by host chemodetection. Seeds of those weed species remain dormant in the soil until germination is triggered by host root exudates.

Studies on the haustorium of Castilleja (Scrophulariaceae). I. The upper haustorium

Canadian Journal of Botany, 1973
The portion of the Castilleja secondary haustorium external to host tissues was investigated at the light- and electron-microscopic levels. One or more haustoria may be present along a single lateral root; however, primary roots of Castilleja may also have haustoria. A localized development of root hairs usually precedes haustorial formation.

Microbiome associated with the Haustorium of Epifagus virginiana.

Proceedings of the West Virginia Academy of Science, 2021
Epifagus virginana is a holoparsitic plant whose only host is the American Beech tree, Fagus grandifolia. Currently, little is known about the specific mechanism used by Epifagus to colonize the tree. It is thought that lignin-like or lignin degradation by-products are needed to signal the colonization process for other members of Orobanchaceae ...

Graniferous tracheary elements in the haustorium of the santalaceae

Planta, 1978
Haustoria of santalaceous root parasites examined have unusual tracheary elements containing granules within their lumina. Benson (1910) thought the granules were starch and that the cells also contained an enucleate protoplast. She believed the cells combined the functions of phloem and xylem conduits and so named them "phloeotracheides" (sic).

Biochemical and nutritional characterization of coconut ( Cocos nucifera L.) haustorium

Food Chemistry, 2018
Study was conducted to determine the biochemical constituents in coconut (Cocos nucifera L.) haustorium, a spongy tissue formed during coconut germination. Results indicated that 100g of dried coconut haustorium contained 1.05±0.2% ash, 44.2±4.6% soluble sugar, 24.5±3.2% starch, 5.50±0.3% protein, 1.99±0.9% fat, 5.72±0.4% soluble dietary fibre, 20.3±1 ...

ANATOMY AND FINE STRUCTURE OF THE MISTLETOE HAUSTORIUM (PHTHIRUSA PYRIFOLIA). I. DEVELOPMENT OF THE YOUNG HAUSTORIUM

American Journal of Botany, 1974
The anatomy and fine structure of the young primary haustorium of Phthirusa pyrifolia (H.B.K.) Eichl. were studied before penetration into the host. The simple internal organization (epidermis, hypodermis, and core parenchyma) which characterizes the radicular disc at germination becomes ...
