Avances en los estudios sobre la interacción Musa spp-Mycosphaerella fijiensis Morelet.

Black leaf streak disease caused by Mycosphaerella fijiensis Morelet [anamorfo: Pseudocercospora fijiensis (Morelet) Deighton], is considered the most destructive and costly foliar disease of bananas and plantain around the world. Taking into account the chemical compounds injure, the increase of fungi resistance to some fungicides besides of, the genetic complexity of Musa spp. resistance to M. fijiensis and the troubles which are present with the genetic improvement of cultivars due to sterility and triploidi, it is necessary to find sustainable alternatives for the management of the disease. To reach this goal the pathogen knowledge and the physiological, genetic and mainly the molecular bases which govern plants interactions to find candidate gene related with the resistance, for the utilization in genetic engineering could be a promissory choice. In this complex scenario biochemical and histological analysis together with the use of different molecular techniques, result of a great contribution to the knowledge of Musa spp.-M. fijiensis pathosystem. At the present work is showed a review of the scientific literature plantpathogen interaction. [ABSTRACT FROM AUTHOR]
