What was compared?
transcriptome profiles of resistant and susceptible Cavendish banana roots infected with Foc TR4 were compared.
What they did
Compared Illumina transcriptomes of resistant vs susceptible Cavendish roots after Foc TR4 inoculation (resistance via somaclonal variation).
What they found
Large-scale expression differences accompany resistance vs susceptibility to Panama disease TR4.
The limits
What it doesn't show
Does not alone deliver a field-ready breeding gene list validated in all cultivars.
