| characterization of novel trichoderma spp. isolates as a search for effective biocontrollers of fungal diseases of economically important crops in argentina. | monoconidial cultures of 33 isolates of trichoderma from buenos aires province, argentina were characterized on the basis of twenty eight morphological, physiological and biochemical features. all of them were screened for proteinase, endochitinase and β-1,3 glucanase activity. universally primed pcr (up-pcr) and inter-simple sequence repeat (issr) techniques were used to examine the genetic variability among isolates, which resulted in 127 bands for the total number of isolates. these results w ... | 2011 | 22805919 |
