Plants are susceptible to different types of environmental pest including pathogens, insects and mites, which cause colossal financial shortfalls (pre- and post-harvest) and threaten global crop production. Yellow mite, Polyphagotarsonemus latus [Banks] (Acari: Tarsonemidae) is one of the major pests of jute crops in Bangladesh, and pest of diverse crops in tropical and subtropical regions. Yellow mites attack, causing significant economic losses, especially fiber, stick and seed yield loss may be 50 to 74%, 37- 57%, and 22-48%, respectively (Kamruzzaman, A. S. M. M., et al, 2013). In conventional jute breeding, it takes approximately a decade to pyramid multiple resistance genes into a jute variety via crossing and backcrossing, while the high pest variability in jute often leads to the rapid break down of resistant cultivars. Thus, application of genome editing for the development of broad-spectrum host resistance has been suggested as an effective approach for breeding varieties resistant to yellow mite. In the present study, for the development of yellow mite resistant jute variety via CRISPR/Cas9, we predict that modification and/or transcriptional activation of Jasmonic acid (JA) pathway candidate gene CoAOC. This system will initiate the upstream and downstream signaling processes network, leading to increased accumulation of associated Jasmonic acid (JA) and thereby host (jute) systemic resistance against yellow mite would be induced.
