6-Hydroxynicotinic Acid From Cucumis melo Inhibits Prehaustorium Formation in Phelipanche aegyptiaca via Disruption of Auxin Signalling Pathway. [PDF]

Mol Plant Pathol
6‐hydroxynicotinic acid inhibits prehaustorium development in Phelipanche aegyptiaca by inhibiting GH3‐mediated auxin conjugation, downregulating key auxin‐responsive genes, and impairing the auxin transporter AUX1. ABSTRACT Phelipanche aegyptiaca, a root holoparasitic weed, severely threatens agricultural productivity due to its detrimental effects ...

Screening of resistance to egyptian broomrape infection in tomato varieties [PDF]

Planta Daninha, 2014
Parasitic weed species of the genus Orobanche are serious threat for the production of several crops in Europe, Africa and Asia. Research on resistant host plant varieties is one of the most effective management strategies for this parasitic weed.

Identification of risk areas for Orobanche cumana and Phelipanche aegyptiaca in China, based on the major host plant and CMIP6 climate scenarios

Ecology and Evolution, 2022
Parasitic broomrape of the genus Orobanche poses a formidable threat to producing many crops in Europe, Africa, and Asia. Orobanche cumana and Phelipanche aegyptiaca are two of China's most destructive root parasitic plants, causing extreme sunflower ...

Study on genetic variability of Orobanche populations infecting tobacco in northwest Iran [PDF]

مجله بیوتکنولوژی کشاورزی, 2014
Orobanche spp. is holoparasitic plant, parasitising roots of different crops. Genetic polymorphism was investigated among and within 3 Orobanche species collected from different regions of northwest Iran, using ISSR markers. Out of 34 ISSR primers tested,

Germination Stimulant Activity of Isothiocyanates on Phelipanche spp.

Plants, 2022
The root parasitic weed broomrapes, Phelipanche spp., cause severe damage to agriculture all over the world. They have a special host-dependent lifecycle and their seeds can germinate only when they receive chemical signals released from host roots.

Altered Mitochondrial Respiration Is Associated With Loss of Nuclear-Encoded OXPHOS Genes in Parasitic Broomrapes. [PDF]

Ecol Evol
The holoparasitic tribe Orobancheae demonstrated significant gene losses in their nuclear‐encoded mitochondrial OXPHOS genes. Despite these losses, high resolution respirometry revealed robust mitochondrial respiration in Orobancheae by shifting activities to fully nuclear encoded alternative complexes. ABSTRACT Parasitic plants, characterized by their

A potential role of heat-moisture couplings in the range expansion of <i>Striga asiatica</i>. [PDF]

Ecol Evol
Our research examines the effects of climate change on the distribution of parasitic weeds, such as Orobanche, Phelipanche, and Striga, which pose threats to global food security. Utilizing satellite data and GBIF observations, we find climate‐induced shifts in habitats and expansion patterns, notably the elevation increase of Striga asiatica ...

Expression of a Defense-Related 3-Hydroxy-3-Methylglutaryl CoA Reductase Gene in Response to Parasitization by Orobanche spp.

Molecular Plant-Microbe Interactions, 1998
Orobanche spp. are angiosperms that live parasitically on the roots of other plants, and are capable of significantly reducing the yield and quality of their crop hosts.

IN VITRO SCREENING OF ANTIMICROBIAL ACTIVITY OF OROBANCHE AEGYPTIACA

Journal of Biopesticides, 2010
ABSTRACT An attempt was made to assess antifungal activity of Orobanche aegyptiaca Pers ethanolic and acetone extracts. Agar well diffusion technique was followed for screening against fungi like Fusarium oxysporum, Trichothecium roseum, Cladosporium herbarum and Trichoderma viridi. The maximum inhibition zone was recorded in acetone extracts of stem.
