Original Article


Dieback and canker diseases are a major problem in ornamental shrubs and trees of Ahvaz, southwestern Iran. Symptomatic stems and branches were collected from two urban parks in the downtown regions of Ahvaz to identify the dieback-causing agents of Lantana camara. Accordingly, two isolates of a new species, Allophoma hayatii sp. nov., were obtained, which are described and illustrated. This species is identified based on morphological characters and analyses of nucleotide sequences of four regions, including internal transcribed spacer 1 and 2 and 5.8S nrDNA (ITS), partial large subunit 28S nrDNA (LSU-D1/D2), a partial sequence of the β-tubulin (tub2) and part of the RNA polymerase II (rpb2). The isolates of A. hayatii generated a well-supported clade in the trees constructed from multi-locus phylogenetic analysis, distinct from other previously known species of Allophoma. Pathogenicity of both isolates was verified by the inoculation of stem fragments of L. camara. These findings confirm A. hayatii as the causal agents of dieback and canker of L. camara in Ahvaz.
