First Report of the Parasitic Plant Orobanche aegyptiaca Infecting Olive

Lily Cultivars Have Allelopathic Potential in Controlling Orobanche aegyptiaca Persoon

As a devastating holoparasitic weed, Orobanche aegyptiaca Persoon. (Egyptian broomrape) causes serious damage to agricultural production and threatens economic development, which has raised widespread concern. The present study was conducted to determine whether lilies have the potential to be used as 'trap crops' for controlling O. aegyptiaca Persoon. In the experiments, the ability of three p...

In vitro infection of host roots by differentiated calli of the parasitic plant Orobanche.

Root parasites of the genus Orobanche are serious weeds in agriculture. An aseptic infection system of host roots using calli of three Orobanche species was developed for the study of host-parasite interaction. The response of calli to various hormonal combinations was studied, because a requirement for infection is the differentiation of root-like protrusions, which are capable of producing ha...

First report of the invasive plant Araujia from Iran

A sample collected from the citrus orchards of the Sari Township, Mazandaran province (N Iran), was determined as Araujia sericifera Brot. (Apocynaceae), according to Markgraf (1972). This species and the genus Araujia, is new to Iran and the region covered by Flora Iranica (Rechinger 1970, 1974).

First Report of Ranavirus Infecting Lungless Salamanders

The strigolactone germination stimulants of the plant-parasitic Striga and Orobanche spp. are derived from the carotenoid pathway.

The seeds of parasitic plants of the genera Striga and Orobanche will only germinate after induction by a chemical signal exuded from the roots of their host. Up to now, several of these germination stimulants have been isolated and identified in the root exudates of a series of host plants of both Orobanche and Striga spp. In most cases, the compounds were shown to be isoprenoid and belong to ...
