A Phelipanche ramosa KAI2 protein perceives strigolactones and isothiocyanates enzymatically

open access: yesPlant Communications, 2021
Phelipanche ramosa is an obligate root-parasitic weed that threatens major crops in central Europe. In order to germinate, it must perceive various structurally divergent host-exuded signals, including isothiocyanates (ITCs) and strigolactones (SLs). However, the receptors involved are still uncharacterized. Here, we identify five putative SL receptors

Mechanism of glyphosate control of Phelipanche aegyptiaca

Planta, 2016
Despite its total reliance on its host plant, the holoparasite Phelipanche aegyptiaca suffers from a deficiency of aromatic amino acids upon exposure to glyphosate. The herbicide glyphosate inhibits 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS), a key enzyme in the biosynthesis of aromatic amino acids.

Global Transcriptomic Analysis Reveals the Mechanism of Phelipanche aegyptiaca Seed Germination [PDF]

open access: yesInternational Journal of Molecular Sciences, 2016
Phelipanche aegyptiaca is one of the most destructive root parasitic plants of Orobanchaceae. This plant has significant impacts on crop yields worldwide. Conditioned and host root stimulants, in particular, strigolactones, are needed for unique seed germination.

Susceptibility of Phelipanche and Orobanche species to AAL-toxin

Planta, 2009
Fusarium and Alternaria spp. are phytopathogenic fungi which are known to be virulent on broomrapes and to produce sphinganine-analog mycotoxins (SAMs). AAL-toxin is a SAM produced by Alternaria alternata which causes the inhibition of sphinganine N-acyltransferase, a key enzyme in sphingolipid biosynthesis, leading to accumulation of sphingoid bases ...

Streptomyces pactum may control Phelipanche aegyptiaca in tomato

Applied Soil Ecology, 2020
Abstract Phelipanche aegyptiaca (syn. Orobanche aegyptiaca), achlorophyllous obligate root parasitic weed attacks economically important crops in several plants families including Solanaceae. Of the Solanaceous crops tomato (Solanum lycopersicum) is the most susceptible.

Phelipanche aegyptiaca management in tomato

Weed Research, 2009
Summary Phelipanche and Orobanche species (broomrapes) are root holoparasitic plants that cause severe damage to economically important crops. Phelipanche and Orobanche spp. are widespread in Mediterranean areas, in Asia and in Southern and Eastern Europe, attacking dicotyledonous crops and depending entirely on their hosts for all nutritional ...
