Search for methylation-sensitive amplification polymorphisms in mutant figs

M. G. F. Rodrigues, Martins, A. B. G., Bertoni, B. W., Figueira, A., and Giuliatti, S., Search for methylation-sensitive amplification polymorphisms in mutant figs, vol. 12, pp. 2267-2280, 2013.

Fig (Ficus carica) breeding programs that use conventional approaches to develop new cultivars are rare, owing to limited genetic variability and the difficulty in obtaining plants via gamete fusion. Cytosine methylation in plants leads to gene repression, thereby affecting transcription without changing the DNA sequence. Previous studies using random amplification of polymorphic DNA and amplified fragment length polymorphism markers revealed no polymorphisms among select fig mutants that originated from gamma-irradiated buds.
