ABSTRACT
Species of the genus Salsola belong to the family Chenopodiaceae and are associated with
large saline areas in eastern Iran. The aim of the study was to isolate and characterize
the endophytic and phytopathogenic fungal communities from non-mycotrophic Salsola
species. Sampling was done from different parts of Salsola plants in the Birjand region in
2017 and 2018. Isolation and identification of fungal isolates were done using biological
characteristics and ITS region sequences. The pathogenicity of the representative isolates
was investigated by cultivating disinfected Salsola incanescens seeds under greenhouse
conditions and inoculating seedlings with a fungal spore suspension from 7 day old fungal
colonies on PDA media. Based on morphological and molecular data, 27 isolates from
11 fungal species were isolated and identified from Salsola tissues. Alternaria alternata,
A. chlamydospora, Aspergillus terreus, Macrophomina phaseolina, Fusarium longipes, Ulocladium
atrum, and Talaromyes pinophilus caused root or stem rotting and yellowing leaf
of S. incanescens under greenhouse conditions. Aspergillus niger induced S. incanescens
crown swelling without any pathogenicity. Clonostachys rosea, F. redolens and F. proliferatum
grew as endophytic fungi on S. incanescens roots. This is the first report of phytopathogenic
M. phaseolina, F. longipes, T. pinophilus, endophytic F. redolens and A. niger
as a swelling agent on S. incanescens.
