The molecular mechanisms of plant recognition, colonization, and nutrient exchange between diazotrophic endophytes plants are scarcely known. Herbaspirillum seropedicae is an endophytic bacterium capable colonizing intercellular spaces grasses such as rice sugar cane. genome H. strain SmR1 was sequenced annotated by Paraná State Genome Programme—GENOPAR. composed a circular chromosome 5,513,887 bp contains total 4,804 genes. sequence revealed that highly versatile microorganism with capacity...
In spite of the taxonomy Aspergillus species Nigri Section being regarded as troublesome, a number methods have been proposed to aid in classification this Section. This work aimed distinguish from foods, grains and caves on basis Polyphasic Taxonomy by utilizing morphologic physiologic characters, sequencing ß-tubulin calmodulin genes. The identification proved useful for some species, such A. carbonarius sp UFLA DCA 01, despite not having totally effective elucidating related niger....
A total of 117 dried fruit samples (black sultanas, white dates, plums, figs and apricots) from different origins were analysed both for toxigenic fungi the presence ochratoxin A. Amongst found, Aspergillus niger was predominant, with 406 isolates, which 15% producers. They followed by ochraceus, 15 isolates 87% ochratoxigenics, carbonarius, only five 60% The average infection rates in black figs, dates sultanas 22.0, 8.0, 4.0, 1.5 0.5%, respectively. apricot not contaminated any or Black...
Microsatellites and gene-derived markers are still underrepresented in the core molecular linkage map of common bean compared to other types markers. In order increase density map, a set new were developed mapped onto RIL population derived from 'BAT93' × 'Jalo EEP558' cross. The EST-SSR first characterized using 24 inbred lines. On average, polymorphism information content was 0.40 mean number alleles per locus 2.7. addition, AFLP RGA based on NBS-profiling method subset sequenced. With...
A total of 119 samples peanut were collected throughout the production chain in São Paulo State, Brazil. The directly plated for determination percentages infection and a polyphasic approach was used to identify Aspergillus section Flavi species. Further, potential aflatoxin by isolates tested using agar plug technique presence aflatoxins peanuts assessed an immunoaffinity column followed quantification HPLC with reverse phase fluorescence detection. limit detection 0.05 0.17μg/kg...
The development of genetic maps for auto-incompatible species, such as the yellow passion fruit ( Passiflora edulis Sims f. flavicarpa Deg.) is restricted due to unfeasibility obtaining traditional mapping populations based on inbred lines. For this reason, linkage were generally constructed using a strategy known two-way pseudo-testcross, monoparental dominant markers segregating in 1:1 fashion. Due lack information from these one parents, two individual (parental) obtained. However,...
The RADP (Random amplified polymorphic DNA) technique was used to detect tissue-culture-induced variations in sugarcane. Plants of the Brazilian variety RB83-5486 propagated via rhizomes and meristem cultures were studied. polymorphism rate for 98 RAPD loci 6.93% when plants derived from meristems. Besides, order evaluate influence number subcultures on generation somaclonal variation, field-grown 10 meristems studied after five subcultivations. Although different rates observed, there no...
M.H.P. FUNGARO, M.L.C. VIEIRA, A.A. PIZZIRANI-KLEINER AND J.L. DE AZEVEDO. 1996. Random amplified polymorphic DNA (RAPD) was used in order to analyse the relationships among 13 isolates of Metarhizium anisopliae var. anisopliae. Six them were isolated from Deois flavopicta (Stal) (Hemiptera—Homoptera: Cercopidae) different regions Brazil. The other seven soil Paraná State Southern grouped by cluster analysis using Dice similarity index. results show that M. are extremely diverse (47%...
Herbaspirillum rubrisubalbicans was first identified as a bacterial plant pathogen, causing the mottled stripe disease in sugarcane. H. can also associate with various plants of economic interest non pathogenic manner.A 21 kb DNA region genome contains cluster 26 hrp/hrc genes encoding for type three secretion system (T3SS) proteins. To investigate contribution T3SS to plant-bacterial interaction process we generated mutant strains M1 carrying Tn5 insertion both hrcN and hrpE genes....
