Abstract
Phylogeographic distribution of Asperisporium caricae isolates in brazilian southeastern and northeastern coastal regions
Highlights
Papaya (Carica papaya L.) is one of the most cultivated and consumed fruits in the tropical and subtropical regions around the world due to its nutrition and digestive properties (WALL, 2006)
Phylogenetic analysis was the instrument applied to 37 taxa; the sequence alignment totaled 341 characters, of them were informative for parsimony, were varying and 321 were conserved
Based on the phylogenetic analysis, we identified isolates at species level; these isolates were allocated to the A. caricae clade, which was well supported by posterior probability = 1.0 (Figure 1)
Summary
Papaya (Carica papaya L.) is one of the most cultivated and consumed fruits in the tropical and subtropical regions around the world due to its nutrition and digestive properties (WALL, 2006). Papaya black spot is caused by the fungus Asperisporium caricae (Speg.) Maubl This disease can hinder crop yield, since it affects plant vigour by reducing its photosynthetic area. There are reports about papaya plants infected by such fungus in different countries such as Brazil, where the black spot disease was first described by Maublanc (MAUBLANC, 1913) in Rio de Janeiro State Since it has been described in several states such as Minas Gerais, Espírito Santo, São Paulo, Santa Catarina, Bahia (SILVA, 2010), Rio Grande do Norte and Amazonas (SOUZA et al, 2014). It has been described in several states such as Minas Gerais, Espírito Santo, São Paulo, Santa Catarina, Bahia (SILVA, 2010), Rio Grande do Norte and Amazonas (SOUZA et al, 2014) This fungus is distributed in almost all Brazilian regions
