Phylogeny and Mycotoxin Profile of Pathogenic <i>Fusarium</i> Species Isolated from Sudden Decline Syndrome and Leaf Wilt Symptoms on Date Palms (<i>Phoenix dactylifera</i>) in Tunisia.

ABSTRACT: In 2017-2018, extensive symptoms of sudden decline and fruit rot were observed on date palms in southern Tunisia. Samples of diseased plants were randomly collected in six localities. Based on morphological identification, Fusarium was the most frequent fungal genus detected. A sequencing of translation elongation factor, calmodulin, and second largest subunit of RNA polymerase II genes was used to identify 63 representative Fusarium strains at species level and investigate their phylogenetic relationships. The main species detected was Fusariumproliferatum, and at a much lesser extent, Fusariumbrachygibbosum, Fusariumcaatingaense, Fusariumclavum, Fusariumincarnatum, and Fusariumsolani.
