    Description: Mature Arabidopsis seeds are enriched in storage proteins and lipids, but lack starch. In the shrunken seed 1 (sse1) mutant, however, starch is favored over proteins and lipids as the major storage compound. SSE1 has 26 percent identity with Pex16p in Yarrowia lipolytica and complements pex16 mutants defective in the formation of peroxisomes and the transportation of plasma membrane- and cell wall-associated proteins. In Arabidopsis maturing seeds, SSE1 is required for protein and oil body biogenesis, both of which are endoplasmic reticulum-dependent. Starch accumulation in sse1 suggests that starch formation is a default storage deposition pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, Y -- Sun, L -- Nguyen, L V -- Rachubinski, R A -- Goodman, H M -- New York, N.Y. -- Science. 1999 Apr 9;284(5412):328-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10195899" target="_blank"〉PubMed〈/a〉

    Publication Date: 1992-11-20
    Description: A gene from the flowering plant Arabidopsis thaliana that encodes an omega-3 desaturase was cloned on the basis of the genetic map position of a mutation affecting membrane and storage lipid fatty acid composition. Yeast artificial chromosomes covering the genetic locus were identified and used to probe a seed complementary DNA library. A complementary DNA clone for the desaturase was identified and introduced into roots of both wild-type and mutant plants by Ti plasmid-mediated transformation. Transgenic tissues of both mutant and wild-type plants had significantly increased amounts of the fatty acid produced by this desaturase.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arondel, V -- Lemieux, B -- Hwang, I -- Gibson, S -- Goodman, H M -- Somerville, C R -- New York, N.Y. -- Science. 1992 Nov 20;258(5086):1353-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉MSU-DOE Plant Research Laboratory, Michigan State University, East Lansing 48824-1312.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1455229" target="_blank"〉PubMed〈/a〉

    Publication Date: 1979-08-10
    Description: The nucleotide sequence of a DNA complementary to human growth hormone messenger RNA was cloned; it contains 29 nucleotides in its 5' untranslated region, the 651 nucleotides coding for the prehormone, and the entire 3' untranslated region (108 nucleotides). The data reported predict the previously unknown sequence of the signal peptide of human growth hormone and, by comparison with the previously determined sequences of rat growth hormone and human chorionic somatomammotropin, strengthens the hypothesis that these genes evolved by gene duplication from a common ancestral sequence. The human growth hormone gene sequences have been linked in phase to a fragment of the trp D gene of Escherichia coli in a plasmid vehicle, and a fusion protein is synthesized at high level (approximately 3 percent of bacterial protein) under the control of the regulatory region of the trp operon. This fusion protein (70 percent of whose amino acids are coded for by the human growth hormone gene) reacts specifically with antibodies to human growth hormone and is stable in E. coli.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martial, J A -- Hallewell, R A -- Baxter, J D -- Goodman, H M -- New York, N.Y. -- Science. 1979 Aug 10;205(4406):602-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/377496" target="_blank"〉PubMed〈/a〉
