Resistance today is virus-specific and incomplete. Kenya approved environmental release of CBSD-resistant transgenic cassava event 4046 (VIRCA Plus) in 2021 and then national performance trials (https://www.businessdailyafrica.com/economy/genetically-modified-cassava-varieties/3946234-5570434-jsxl6qz/index.html), but it targets one disease; CMD2 resistance maps to MePOLD1, is lost through tissue culture and has been overcome by novel satellite DNAs (Nat Commun 2022, https://www.nature.com/articles/s41467-022-31414-0.pdf), and no effective CBSD resistance exists in germplasm. Banana bunchy top virus has no released resistant variety; IITA is screening 72 varieties and Malawi field data suggest immunity will need a multi-faceted strategy (https://eprints.qut.edu.au/228515). In potato, Ry-sto gives broad resistance to PVY isolates and a January 2026 Plants study reports transgenic Kennebec resistant to PVY and PLRV, but most cultivars lack broad PVY resistance and no resistance to PMTV is known (https://www.mdpi.com/2223-7747/15/3/355). Honest limit: single-virus resistance genes and RNAi constructs are published, so tasks that re-create them are known answers; the open work is durable, stacked or broad-spectrum resistance across each crop's virus complex, and each task needs its own basis.
