  1. 21. Studies of the role of tRNA-isopentenyl-transferases in the formation of cytokinins

    University essay from SLU/Dept. of Plant Biology and Forest Genetics (until 131231)

    Author : Grzegorz Furman ; [2011]
    Keywords : Arabidopsis thaliana; Physcomitrella patens; Saccharomyces cerevisiae; tRNA isopentyltransferases; cytokinin biosynthesis;

    Abstract : Plant tRNA isopentenyltransferases (tRNA-IPT, EC 2.5.1.8) have two roles, modification of tRNA and contribution to cytokinin synthesis. READ MORE

  3. 22. DNA methylations : A comparison of four genes between Red Junglefowl and White Leghorn

    University essay from Molekylär genetik

    Author : Johan Bélteky; [2011]
    Keywords : High-resolution melting; DNA methylation; White Leghorn; Red Junglefowl; domestication;

    Abstract : Domestication of animals has given rise to a great phenotypic divergence in selected animals and rapidly generated species of animals more accustomed to human contact and social interactions within the species. Previous studies in chickens (Gallus gallus) have managed to find behavioral and adaptive differences between Red Junglefowl (RJF) and White Leghorn (WL), differences inherent to the domestication process.

  4. 23. Histone modifications after DNA damage affect survival in Schizosaccharomyces pombe

    University essay from Institutionen för livsvetenskaper

    Author : Abdul Mateen Rajput; [2010]
    Keywords : Epigenetics; DNA damage; S. pombe; yeast; histone modification; chromatin; life sciences; gene deletion; gene tagging; pcr; mms; 4-nqo; brl1; brl2; Epigenetics، ڈی این اے کو نقصان، ایس pombe، خمیر، histone تبدیلی، chromatin، زندگی سائنس، جین خارج، جین ٹیگنگ، پی سی آر، ایم ایم ایس،; Epigenetik; DNA-skada; S. pombe; jäst; histon modifiering; kromatin biovetenskap; gendeletion; gen taggning; PCR; MMS; 4-nqo; brl1; brl2;

    Abstract : S. cerevisiae Ada2 and Bre1 has a role in histone post-translational modifications. Deletion of these genes causes deficiency in acetylation (Ada2) or ubiquitination (Bre1) of histones. Further, mutants lacking these genes or homologous genes showed different phenotypes in human and S. READ MORE

  5. 24. Transforming the Brute : On the Ethical Acceptability of Creating Painless Animals

    University essay from Centrum för tillämpad etik

    Author : Brent Mittelstadt; [2009]
    Keywords : transforming; brute; nociception; pain; genetic; engineering; manipulation; modification; modify; gene; genes; bernard; rollin; animal; microencephalic; lumps; decerebrate; aml; amls; painless; painlessness; integrity; dignity; rights; companionship; telos; alteration; biomedicine; biomedical; experiment; experimentation; agriculture; farm; suffering; distress; capacity; bioethics; ethics; applied; mice; scn9a; nav1.7; gene; therapy; germ; line;

    Abstract : Transforming the Brute addresses the ethical acceptability of creating painless animals for usage in biomedical experimentation.  In recent decades the possibility of creating genetically decerebrate animals or AMLs for human ends has been discussed in scientific, academic, and corporate communities.

  6. 25. Transcriptomes of Populus lines modified in Pectin methylesterase expression reveal activation of oxidative stress signaling pathways

    University essay from SLU/Dept. of Forest Genetics and Plant Physiology

    Author : David Öhman; [2006]
    Keywords : Populus spp.; tyloses; wood formation; callose; oligogalacturonic acid; oxidative stress signaling pathways; pectin methylesterase; microarray; peroxidase activity; H2O2;

    Abstract : Pectin methylesterases (PMEs) catalyze the demethylesterification of cell wall polygalacturonans, and this is thought to play important roles in cell wall extensibility and intercellular adhesion. In addition, PMEs influence many physiological processes, such as stem elongation, root development, fertilization, fruit softening, and xylogenesis. READ MORE
