Endophytic fungi occurring in fennel, lettuce, chicory, and celery-commercial crops in southern Italy
No full textThe 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 three to three species of Acremonium) inoculated
on lettuce plants grown in gnotobiosis was assessed by recording plant height, root
length and dry weight, collar diameter, root necrosis, and leaf yellowing. P. tabacinum
and three species of Acremonium, inoculated on gnotobiotically grown lettuce plants,
showed pathogenic activity that varied with the fungal isolate. Lettuce plants inoculated
with the isolates Ak of Acremonium kiliense, Ac of Acremonium cucurbitacearum, and P35 of
P. tabacinum showed an increased root growth, compared to the non-inoculated control.
The high frequency of P. tabacinum isolation recorded in lettuce plants collected in Bari
and Metaponto, and in fennel plants from Foggia agricultural districts, suggests a relationship
not only between a crop species and P. tabacinum, but also between the occurrence of
the endophyte and the crop rotation history of the soil.
