| analysis of population structure of aspergillus flavus from peanut based on vegetative compatibility, geographic origin, mycotoxin and sclerotia production. | isolates of aspergillus flavus obtained from a new growing peanut region in argentina (formosa province) were examined for aflatoxin types b and g and cyclopiazonic acid (cpa) production. sclerotia diameters and the number of sclerotia produced per square centimetre were also determined for each isolate. they were tested by vegetative compatibility group analysis to investigate their genetic relatedness and correlate the results with vegetative compatibility groups previously described from the ... | 2004 | 15135580 |
| molecular phylogeography of the chagas' disease vector triatoma infestans in argentina. | triatoma infestans is the main vector of chagas' disease in south america between latitudes 10°s and 46°s. a multilocus microsatellite data set of 836 individuals from 27 populations of t. infestans, from all its range of distribution in argentina, was analyzed. our results favor the hypothesis of two independent migration events of colonization in argentina and secondary contacts. the majority of the populations of the western provinces of catamarca, la rioja, san juan and the west of cordoba p ... | 2011 | 21224874 |
