The origin of novel traits is recognized as an important process underlying many major evolutionary radiations. We studied the genetic basis for evolution haustoria, feeding organs parasitic flowering plants, using comparative transcriptome sequencing in three species Orobanchaceae. Around 180 genes are upregulated during haustorial development following host attachment at least two species, and these enriched proteases, cell wall modifying enzymes, extracellular secretion proteins....
The Parasitic Plant Genome Project has sequenced transcripts from three parasitic species and a nonparasitic relative in the Orobanchaceae with goal of understanding genetic changes associated parasitism. studied span trophic spectrum free-living nonparasite to obligate holoparasite. used were Triphysaria versicolor , photosynthetically competent that opportunistically parasitizes roots neighboring plants; Striga hermonthica hemiparasite an need for host; Orobanche aegyptiaca holoparasite...
The long co-existence of broomrapes and their hosts within the same environment has culminated in a strong adaptation effective parasitism. As first step specialization parasitic process, seed receptors plant species vary ability to recognize compounds released by hosts. This work aims investigate potential patterns for reception requirements needed activate germination Orobanche Phelipanche species. Induction seeds nine Pheliphanche root exudates 41 was studied subjected biplot multivariate...
Summary Weedy Orobanche and Phelipanche species are important in Southern Eastern Europe, the Middle East North Africa, have recently been reported USA, Australia some countries South America. Rather than being controlled, problem is increasing, both intensity acreage. Large areas of new territory at risk invasion, if care not immediately taken to limit introduction parasitic seeds educate farmers others be alert for infestations. There an urgent need re‐evaluate novel integrated management...
Abstract Strigolactones are apocarotenoids regulating shoot branching. They also known to be exuded by plant roots at very low concentrations, stimulating hyphal branching of arbuscular mycorrhizal fungi and germination root parasitic weed seeds. We show that strigolactones play a major role in host specificity Orobanche Phelipanche (the broomrapes) seed germination. This observation confirms host-derived stimulants an important component determining the these plants. Weedy broomrape species...
Broomrape weeds (Orobanche and Phelipanche spp.) are root holoparasites that feed off a wide range of important crops. Among them, Orobanche crenata attacks legumes complicating their inclusion in cropping systems along the Mediterranean area West Asia. The detrimental effect broomrape parasitism crop yield can reach up to 100% depending on infection severity broomrape-crop association. This work provides field data consequences O. three legume crops i.e. faba bean, pea grass pea. Regression...
Faba bean yield is severely constrained in the Mediterranean region and Middle East by parasitic weeds Orobanche crenata, O. foetida, Phelipanche aegyptiaca. Seed germination of these triggered upon recognition host root exudates. Only recently faba accessions have been identified with resistance based low induction seed germination, but underlying mechanism was not identified. Strigolactones are a group terpenoid lactones involved plants. Our LC-MS/MS analysis exudates susceptible accession...
F ernández ‐A paricio M, G arcía ‐G arrido JM, O campo JA & R ubiales D (2010). Colonisation of field pea roots by arbuscular mycorrhizal fungi reduces Orobanche and Phelipanche species seed germination. Weed Research 50 , 262–268. Summary Pea ( Pisum sativum ) is an important grain legume crop whose cultivation in the Mediterranean basin West Asia severely constrained infection weedy root parasite crenata (crenate broomrape). a false host other such as O. minor foetida aegyptiaca . In...
Orobanche and Phelipanche species (the broomrapes) are root parasitic plants, some of which cause heavy yield losses on important crops. The development herbicides based natural metabolites from microbial plant origin, targeting early stages development, might contribute to the reduction broomrape seed bank in agricultural soils. Therefore, effect belonging different classes compounds germination radicle was assayed vitro. Among tested, epi-sphaeropsidone, cyclopaldic acid, those...
