Schematic representation of the two constructs used to generate recombinant baculoviruses expressing the recombinant proteins RHDV-VP60 and PCV2-Cap.

<p>A) Expression cassette used to express the recombinant proteins under the control of the <i>polh</i> promoter in a conventional TB(-) baculovirus. B) Expression cassette used to express the recombinant proteins in a TB(+) baculovirus containing all genetic regulatory elements, including the transactivation elements encoded by <i>Ac-ie-01</i> sequence, the enhancer sequence <i>hr1</i>, and the combination of promoters <i>p6</i>.<i>9</i> and <i>p10</i>.
