6-Hydroxynicotinic Acid From Cucumis melo Inhibits Prehaustorium Formation in Phelipanche aegyptiaca via Disruption of Auxin Signalling Pathway. [PDF]
Mol Plant Pathol6‐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 ...

Has the Striga problem been solved? A field perspective critique of recent progress. [PDF]
Pest Manag SciThe potential field efficacy of recently proposed breeding, biocontrol, suicidal germination, gene editing and transgenic solutions for Striga control is critically evaluated and mostly found wanting improvements. Abstract Three root‐parasitic witchweed (Striga) species can cause up to total loss of grain and legume crops for millions of farmers in ...

Spring Forward: Reproductive Phenology of the Holoparasite <i>Lathraea squamaria</i> (Orobanchaceae). [PDF]
Plant Environ InteractLathraea squamaria is a peculiar holoparasitic plant. Here, we show that over a 14‐year period, key stages in the reproductive phenology of this parasite have started significantly earlier. Most remarkably, initial dates of flower anthesis and seed release now occur five and nine days earlier, respectively, when compared to 2007. ABSTRACT Lathraea is a

ABA signaling components in Phelipanche aegyptiaca [PDF]
Scientific Reports, 2019 AbstractObligate root holoparasite Phelipanche aegyptiaca is an agricultural pest, which infests its hosts and feeds on the sap, subsequently damaging crop yield and quality. Its notoriously viable seed bank may serve as an ideal pest control target. The phytohormone abscisic acid (ABA) was shown to regulate P.

Weed Technology, 2022 AbstractBranched broomrape, an obligate root parasitic weed, has recently re-emerged in tomato fields in several California counties. California produces more tomato than any other state, and the outbreak of this noxious weed could potentially wreak havoc on the industry’s economy.

Parasitic Plant-Host Interactions: Molecular Mechanisms and Agricultural Resistance Strategies. [PDF]
Adv Sci (Weinh)Parasitic plants devastate global agriculture through sophisticated molecular interactions with host crops. This review synthesizes current understanding of parasitic plant‐host interactions, from strigolactone‐mediated germination and haustorium formation to host defense mechanisms.

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

Multiple genotypes of Phelipanche ramosa indicate repeated introduction to the Americas. [PDF]
Am J BotAbstractPremisePhelipanche ramosa is an economically damaging parasitic plant that has been reported in North America since the late 1800s. While this species comprises a variety of genetically distinct host races in its native range, the genetic composition of adventive populations in the New World remains unexplored. On the basis of morphological and

Morphological diversity of pistil stigmas and its taxonomic significance of representatives of holoparasitic Orobanchaceae from Central Europe [PDF]
PhytoKeys, 2022 The stigma is the terminal part of the carpel which receives pollen during the pollination process. Although the role of the stigmas in pollination is the same for all angiosperms, stigmas structures are very diverse.
