AU: Scientists studying wild mangoes to fight fungal disease

Fresh Plaza: Wild mangoes could hold the key to increasing resistance to a devastating disease of the commercial crop. Mango anthracnose is a fungal disease which can cause large, sunken black bruises on the fruit, making it unsaleable. While  the   disease  can  be  controlled  with  chemical  sprays, 
most of the commercial varieties have little or poor natural resistance. So researchers in Queensland are now looking at the wild relatives of mangoes to see if they could provide a genetic boost to resistance levels. However, principal horticulturalist Dr Ian Bally says genetically modified mangoes   aren't  on   the   horizon.   "Genetic   engineering   theoretically   is

possible, but there's a couple of steps in the process that require tissue culturing and regeneration of mangoes from tissue culture and that technology is not well developed in mango and probably would be a bit of a barrier." Source: Fresh Plaza
