Variable intron content of the NADH dehydrogenase subunit 4 gene of plant mitochondria
Summary The gene nad4, encoding subunit four of the mitochondrial NADH dehydrogenase complex I, has been isolated and characterized from turnip, Brassica campestris. The 8 kb turnip nad4 gene contains four exons, which potentially encode a NAD4 polypeptide of 495 amino acids, and three large group I...

Variable intron content of the NADH dehydrogenase subunit 4 gene of plant mitochondria |
| abstract |
Summary The gene nad4, encoding subunit four of the mitochondrial NADH dehydrogenase complex I, has been isolated and characterized from turnip, Brassica campestris. The 8 kb turnip nad4 gene contains four exons, which potentially encode a NAD4 polypeptide of 495 amino acids, and three large group II introns. Northern analysis identifies an abundant 2 kb transcript that most likely serves as the nad4 mRNA, while several larger transcripts (putative splicing intermediates) are also detected. Analysis of the nad4 locus in three distantly related dicotyledons indicates that introns 2 and 3 are optional. Mung bean has the same nad4 organization as turnip, whereas spinach nad4 contains introns 1 and 3, and lettuce nad4 has intron 1 only. We infer that all three group II introns were present in the nad4 gene of an angiosperm common ancestor and have persisted in certain lineages for over 200 million years, with two of the introns having been lost in other lineages. |

The 8 kb turnip nad4 gene contains four exons, which potentially encode a NAD4 polypeptide of 495 amino acids, and three large group II introns. Northern analysis identifies an abundant 2 kb transcript that most likely serves as the nad4 mRNA, while several larger transcripts (putative splicing intermediates) are also detected. Analysis of the nad4 locus in three distantly related dicotyledons indicates that introns 2 and 3 are optional. Mung bean has the same nad4 organization as turnip, whereas spinach nad4 contains introns 1 and 3, and lettuce nad4 has intron 1 only. We infer that all three group II introns were present in the nad4 gene of an angiosperm common ancestor and have persisted in certain lineages for over 200 million years, with two of the introns having been lost in other lineages.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Springer Online Journal Archives 1860-2002</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Gass, David A.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Makaroff, Christopher A.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Palmer, Jeffrey D.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">in</subfield><subfield code="t">Current genetics</subfield><subfield code="d">1979</subfield><subfield code="g">21(1992) vom: Apr./Mai, Seite 423-430</subfield><subfield code="w">(DE-627)NLEJ18898433X</subfield><subfield code="w">(DE-600)1458984-9</subfield><subfield code="x">1432-0983</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:21</subfield><subfield code="g">year:1992</subfield><subfield code="g">month:04/05</subfield><subfield code="g">pages:423-430</subfield><subfield code="g">extent:8</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://dx.doi.org/10.1007/BF00351705</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-SOJ</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">21</subfield><subfield code="j">1992</subfield><subfield code="c">4/5</subfield><subfield code="h">423-430</subfield><subfield code="g">8</subfield></datafield></record></collection>
