In some cases, however, it is difficult to efficiently disrupt both paralogous genes using a single pair of TALENs in <jats:italic>Xenopus laevis<\/jats:italic> because of its polyploidy. Here, we report targeted mutagenesis of multiple and paralogous genes using two pairs of TALENs in <jats:italic>X.\u00a0laevis<\/jats:italic>. First, we show simultaneous targeted mutagenesis of three genes, tyrosinase paralogues (<jats:italic>tyra<\/jats:italic> and <jats:italic>tyrb<\/jats:italic>) and enhanced green fluorescent protein (egfp) by injection of two TALENs pairs in transgenic embryos carrying egfp. Consistent with the high frequency of both severe phenotypic traits, albinism and loss of GFP fluorescence, frameshift mutation rates of <jats:italic>tyr<\/jats:italic> paralogues and egfp reached 40\u201380%. Next, we show early introduction of TALEN\u2010mediated mutagenesis of these target loci during embryogenesis. Finally, we also demonstrate that two different pairs of TALENs can simultaneously introduce mutations to both paralogues encoding histone chaperone with high efficiency. Our results suggest that targeted mutagenesis of multiple genes using TALENs can be applied to analyze the functions of paralogous genes with redundancy in <jats:italic>X.\u00a0laevis<\/jats:italic>.<\/jats:p>","DOI":"10.1111\/dgd.12105","type":"journal-article","created":{"date-parts":[[2013,12,12]],"date-time":"2013-12-12T02:14:41Z","timestamp":1386814481000},"page":"108-114","source":"Crossref","is-referenced-by-count":28,"title":["Targeted mutagenesis of multiple and paralogous genes in <i>Xenopus laevis<\/i> using two pairs of transcription activator\u2010like effector nucleases"],"prefix":"10.1111","volume":"56","author":[{"given":"Yuto","family":"Sakane","sequence":"first","affiliation":[{"name":"Department of Mathematical and Life Sciences Graduate School of Science Hiroshima University 1\u20103\u20101 Kagamiyama Higashi\u2010Hiroshima Hiroshima 739\u20108526 Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tetsushi","family":"Sakuma","sequence":"additional","affiliation":[{"name":"Department of Mathematical and Life Sciences Graduate School of Science Hiroshima University 1\u20103\u20101 Kagamiyama Higashi\u2010Hiroshima Hiroshima 739\u20108526 Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keiko","family":"Kashiwagi","sequence":"additional","affiliation":[{"name":"Institute for Amphibian Biology Graduate School of Science Hiroshima University 1\u20103\u20101 Kagamiyama Higashi\u2010Hiroshima Hiroshima 739\u20108526 Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akihiko","family":"Kashiwagi","sequence":"additional","affiliation":[{"name":"Institute for Amphibian Biology Graduate School of Science Hiroshima University 1\u20103\u20101 Kagamiyama Higashi\u2010Hiroshima Hiroshima 739\u20108526 Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Yamamoto","sequence":"additional","affiliation":[{"name":"Department of Mathematical and Life Sciences Graduate School of Science Hiroshima University 1\u20103\u20101 Kagamiyama Higashi\u2010Hiroshima Hiroshima 739\u20108526 Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ken\u2010ichi T.","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Department of Mathematical and Life Sciences Graduate School of Science Hiroshima University 1\u20103\u20101 Kagamiyama Higashi\u2010Hiroshima Hiroshima 739\u20108526 Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2013,12,11]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tig.2011.08.003"},{"key":"e_1_2_7_3_1","article-title":"TALENs efficiently disrupt the target gene in Iberian ribbed newts (Pleurodeles waltl), an experimental model animal for regeneration","author":"Hayashi T.","year":"2013","journal-title":"Dev.
