One approach is to produce fusion protein toxins for the control of these pests. Two protein toxins, Hvt (\u03c9-atracotoxin from <jats:italic>Hadronyche versuta<\/jats:italic>) and onion leaf lectin, were translationally fused to evaluate the negative effects of fusion proteins on <jats:italic>Phenacoccus solenopsis<\/jats:italic> (mealybug), a phloem-feeding insect pest. Hvt was cloned both N-terminally (HL) and then C-terminally (LH) in the fusion protein constructs, which were expressed transiently in <jats:italic>Nicotiana tabacum<\/jats:italic> using a <jats:italic>Potato Virus X<\/jats:italic> (PVX) vector. The HL fusion protein was found to be more effective against <jats:italic>P. solenopsis<\/jats:italic>, with an 83% mortality rate, as compared to the LH protein, which caused 65% mortality. Hvt and lectin alone caused 42% and 45%, respectively, under the same conditions. Computational studies of both fusion proteins showed that the HL protein is more stable than the LH protein. Together, these results demonstrate that translational fusion of two insecticidal proteins improved the insecticidal activity relative to each protein individually and could be expressed in transgenic plants for effective control of sucking pests.<\/jats:p>","DOI":"10.1038\/s41598-018-23138-3","type":"journal-article","created":{"date-parts":[[2018,3,13]],"date-time":"2018-03-13T16:16:38Z","timestamp":1520957798000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Computational and biological characterization of fusion proteins of two insecticidal proteins for control of insect pests"],"prefix":"10.1038","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3195-8740","authenticated-orcid":false,"given":"Shaista","family":"Javaid","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sehrish","family":"Naz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Imran","family":"Amin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9675-934X","authenticated-orcid":false,"given":"Georg","family":"Jander","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8530-8711","authenticated-orcid":false,"given":"Zaheer","family":"Ul-Haq","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shahid","family":"Mansoor","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2018,3,19]]},"reference":[{"key":"23138_CR1","doi-asserted-by":"crossref","first-page":"775","DOI":"10.1128\/MMBR.62.3.775-806.1998","volume":"62","author":"E Schnepf","year":"1998","unstructured":"Schnepf, E. et al.
