Citrus Black Rot

Citrus black rot caused by Alternaria spp. is significant postharvest problem in Iran. The causal agent of black rot was originally identified as A. citri by Ellis and Pierce. The genus Alternaria circumscribes considerable morphological diversity and citrus black rot may be caused by more than one morphospecies in addition to A. citri. Morphological identification of small-spored Alternaria spp. is difficult. Phylogenetic analysis was performed on 7 small-spored Alternaria isolates from black rotted citrus fruit in Iran using sequence data from an anonymous locus, OPA10-2. Samples were collected from navel oranges in Mazandaran province in the north of Iran. All isolates caused black rot in a fruit inoculation assay with Navel and Valencia oranges and significant differences were observed between cultivars and among isolates. No association was found between morphological classification and phylogenetic clade. We identified A. tenuissima (ALT 6) as the causal agents of citrus black rot. OMICS Group International is one of the leading Open Access Publishers which is publishing 700+ peer-reviewed journals with the support of 50,000+ editorial board members as editorial team and aimed to disseminate the scholarly knowledge to the scientific society. OMICS Group also organizing 3000+ International Scientific Conferences and events yearly all over the world with the support of 1000+ Scientific associations worldwide.
