Alternaria species causing pomegranate and citrus fruit rots in Albania

Abstract The fungal genus Alternaria is a relevant pathogen for several commodities including citrus and pomegranate fruits. On citrus, it mainly causes brown spots on fruits leaves, whereas pomegranate, mostly fruit heart rot. In the present study presence of rots cultivated in Albania was assessed. Representative were collected from different regions. Nineteen thirteen spp. isolates obtained samples, respectively. identified at species morphotype level. Micro macroscopic features separated into four morphotypes. BLAST phylogenetic analysis using SCAR Marker OPA1-3 confirmed isolate identity. All 32 proved to be alternata belonged , followed by limoniasperae tenuissima . strains possess pksI gene alternariol biosynthesis. Citrus tested genes biosynthesis phytotoxins ACT ACR, but none them them. Concluding, might represent treat production Albania, thus effective control means are needed.
