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.
