Inactivation of the FCY2 (cytosine permease), FCY1 deaminase), and FUR1 (uracil phosphoribosyltransferase) genes in Candida lusitaniae produced two patterns resistance to flucytosine. Mutant fur1 demonstrated 5-fluorouracil, whereas mutants fcy1 fcy2 fluconazole presence subinhibitory flucytosine concentrations.
Freshly harvested barley seeds are considered as dormant since they do not germinate at temperatures above 20 degrees C. This dormancy is broken during dry storage. Molecular regulation of was investigated using cDNA-AFLP to identify transcripts differentially expressed in and non-dormant embryos. Transcript patterns embryos from both imbibed for 5 h 30 C, a temperature which expressed, were compared. Thirty-nine Transcript-Derived Fragments (TDF) that reproducibly among treatments...
Certain amino acids induce inhibitory effects in plant growth due to feedback inhibition of metabolic pathways. The patterns depend on species and the developmental stage. Those with action specific weeds could be utilized as herbicides however their use for weed control has not been put into practice. Orobanche minor is a that parasitizes red clover. O. germination stimulated by clover root exudates. subsequent seedling an obligated parasite must attach quickly withdraw its nutrients. Early...
Branched broomrape (Phelipanche ramosa (L.) Pomel) is an achlorophyllous root parasitic plant with a wide host range. Its complex management leading to the abandonment of tobacco or oilseed rape cultivation in most affected regions France. Among regulation factors, soil microorganisms such as fungi seem be relevant biocontrol lever. The aim this work was detect potential mycoherbicides among fungal endophytic colonizers P. parasitizing tobacco. Our hypothesis that both inhibitory seed...
Phelipanche ramosa is a parasitic plant that infects numerous crops worldwide. In Western Europe it recently expanded to new host crop, oilseed rape, in which can cause severe yield losses. We developed 13 microsatellite markers for P. using next-generation 454 sequencing data. The polymorphism at each locus was assessed sample of 96 individuals collected France within 6 fields cultivated with tobacco, hemp or rape. Two loci were monomorphic. At the other 11 loci, number alleles and expected...
Rhamphicarpa fistulosa (Hochst.) Benth. (Scrophulariaceae) is an annual facultative root-parasitic weed found in the lowlands and floodplains of tropical Africa. It has been reported to be major biotic constraint rice cultivation Savannah region Togo. A survey was conducted 2012 determine its geographical spread collect information on farmers' knowledge control. An investigation based semi-open questions carried out among people visited. 80% 33 The period abundance August-September with...
Summary Phelipanche ramosa is a generalist parasitic weed known to cause yield losses in various crops, especially winter oilseed rape, its new preferred host France. This plant also able complete life cycle on many Brassicaceae weeds, which are thus important alternative hosts. We studied set of 14 common weeds and characterised their ability induce the germination three genetically distinct pathovars P. , based vitro experiments. then investigated whether phylogenetic relatedness among...
Phelipanche ramosa (L.) Pomel (branched broomrape) is a holoparasitic plant that reproduces on crops and also weeds, which contributes to increase the parasite seed bank in fields. This extracts all its nutrients at host's expense so host-parasite trophic relationships are crucial determine host growth. study quantified intensity with P. draws assimilates from analyzed whether it varied species, phenological stage growth rate. A greenhouse experiment was conducted three species: crop species...
Summary Phelipanche ramosa (Branched broomrape) is an obligate root parasitic plant that a major pest of oilseed rape in France. Knowledge on seed viability and dormancy under field conditions crucial to understand how control P. ramosa, but as yet unknown. Our study aimed quantify these processes with 2‐year burial experiment. Two genetically distinct populations were studied, collected winter (population O) hemp H). Seed mortality was very low both (4–7% per year). Although seeds are...
Branched broomrape, Phelipanche ramosa (L.) Pomel, is a globally distributed parasitic weed of economic importance. In Europe, where it native, can infest several crops, notably tomato, tobacco, and hemp. western France, has recently adapted to new host crop, oilseed rape, causing substantial damage. The aim this study was investigate the evolutionary relationships genetic differentiation among P. populations infesting different hosts. We collected 1611 samples from 109 fields cultivated...
