Pathogenicity variation in Fusarium verticillioides populations
isolated from maize in northern Italy / G. Venturini, G. Assante, S.L. Toffolatti, A. Vercesi. - In: MYCOSCIENCE. - ISSN 1340-3540. - 54:4(2013), pp. 285-290. [10.1016/j.myc.2012.10.007]
Abstract:
One hundred and eighty one strains were selected among Fusarium verticillioides populations
isolated from maize samples collected in three fields located in northern Italy. All
the isolates were tested for their pathogenicity on maize seeds by assessing the seed
germination percentages and the percentage infection indexes concerning seed colonization,
radicle decay and coleoptile rot. Fusarium verticillioides strains did not affect seed
germination even in presence of high seed colonization, but showed a variable pathogenic
behavior according to the maize growth stages. Seedborne F. verticillioides population as
well as strains isolated at maturity was effective in seed colonization and in inducing
coleoptile rot, not causing however serious radicle decay. Only populations isolated at
seedling and pre-silking stages showed high radicle decay ability. These results provide
baseline information on F. verticillioides pathogenicity. They constitute an important input
for further investigation of F. verticillioides biology in order to define its evolutionary
potential.
