Virus pisang berjalur (BSV) ialah virus tumbuhan patogenik darioada keluarga Caulimoviridae.

Virus pisang berjalur pertama kali dikenal pasti pada 1958 di Côte d'Ivoire dan kini terdapat di banyak negara di kawasan tropika.^[1] Gejala utama penyakit in ialah jaluran klorosis pada daun pisang dan belahan pseudostem. Pada peringkat akhir penyakit ini, jaluran ini berkemungkinan menjadi nekrotik, dan bahagian teras pseudostem akan mereput, akhirnya mengakibatkan kematian tumbuhan.^[2]

Walaupun virus ini tidak perlu menyempurnakan kitar hayat, ahli Caulimoviridae (serta Geminiviridae ) telah terbukti menyepadukan genom sendiri ke dalam perumah.^[3] Apabila perumah mengalami tekanan, genom bersepadu BSV mampu direkombinasikan semula kepada bentuk episomnya, namun mekanisme proses ini tidak difahami dengan baik.^[4] Walaupun terdapat beberapa salinan BSV dalam spesies Musa, hanya satu yang kelihatan berdaya hidup dalam konteks ini. Salinan lain mengalami mutasi yang menghasilkan kodon penamat pramatang atau menyebabkan ketidakfungsian genom.^[5]
