| physiological and biochemical characterization of trichoderma harzianum, a biological control agent against soilborne fungal plant pathogens. | monoconidial cultures of 15 isolates of trichoderma harzianum were characterized on the basis of 82 morphological, physiological, and biochemical features and 99 isoenzyme bands from seven enzyme systems. the results were subjected to numerical analysis which revealed four distinct groups. representative sequences of the internal transcribed spacer 1 (its 1)-its 2 region in the ribosomal dna gene cluster were compared between groups confirming this distribution. the utility of the groupings gene ... | 1997 | 9251205 |
| endophytic fungi occurring in fennel, lettuce, chicory, and celery--commercial crops in southern italy. | the occurrence of endophytic fungi in fennel, lettuce, chicory, and celery crops was investigated in southern italy. a total of 186 symptomless plants was randomly collected and sampled at the stage of commercial ripeness. fungal species of acremonium, alternaria, fusarium, and plectosporium were detected in all four crops; plectosporium tabacinum was the most common in all crop species and surveyed sites. the effect of eight endophytic isolates (five belonging to plectosporium tabacinum and thr ... | 2008 | 18222676 |
