It's not easy being yellow.But as now is face two separated con?? demix which threaten the pluck the fruit off x tables.Fortunately,reseachers have now x banana's DNA,producing the Geno x the banana briday that may hold the secret to the field in the diseases.The reoprt is in the Journal Nature.Today,half of all banana including the one you've probably by belong to the cavan dishxx.This popularity stands apart from having no seeds but this trade also remove sexual reproduction from the equation.The bananas are those all genetically identical and indentically bond their x to the two fungus epidemics x disease and x diseaes.Researchers sequenced the geno more the banana variety called the age Behan who's gene contribute to the cavan dish while the geno shows where the scrupe bents in the history of planet evolution.It could also help researchers understand why DH behan unlikely its desand is resistent to its the fungus behind both Pananma and x disease.Knowing the Gene is responbile for the resistent could help creators creat stronger,more resistent bananas which have a lot of appear.
