  2. 1. Evolution of genetic mechanisms regulating reproductive development in plants : Characterisation of MADS-box genes active during cone development in Norway spruce

    Author : Jens Sundström; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Picea abies; evolution; flower development; transcription factor; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; fysiologisk botanik; Physiological Botany;

    Abstract : The reproductive organs of conifers and angiosperms differ in morphology in several fundamental respects. The conifer Norway spruce (Picea abies) form pollen and seed cones from separate meristems whereas angiosperms bear bipartite flowers with sepals and petals surrounding two inner whorls of stamens and carpels.

  4. 2. Meristem Maintenance in Arabidopsis thaliana

    Author : Alessia Para; Annika Sundås Larsson; Jan Traas; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Life sciences and physical sciences; Arabidopsis thaliana; development; shoot apical meristem; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : The shoot apical meristem (SAM) is the structure that shapes the aerial architecture of the plant, by producing lateral organs throughout development. In the model plant Arabidopsis thaliana, the SAM is always identifiable as a characteristic dome, whether it is found in the centre of a rosette of leaves or at the tip of an inflorescence.

  5. 3. Analysis of Two Transcriptional Regulators that Affect Meristem Function : Arabidopsis thaliana TERMINAL FLOWER2 and Picea abies APETELA2

    Author : Lars Nilsson; Annika Sundås Larsson; Peter Engström; Thomas Laux; Uppsala universitet; []
    Keywords : Developmental biology; Arabidopsis thaliana; Picea abies; gene regulation; development; meristem; Utvecklingsbiologi;

    Abstract : The aerial plant body is derived from undifferentiated cells in the shoot apical meristem that in Arabidopsis thaliana is active throughout the plant life cycle. Upon transition to flowering the activity of the meristem is altered and the meristem starts to produce secondary inflorescences and floral meristems instead of leaves. READ MORE

  6. 4. Amino acids with relevance to health, climate and the environment : Development of mass spectrometric methods

    Author : Javier Zurita; Leopold Ilag; Ulrika Nilsson; Margareta Törnqvist; Natalia Tretyakova; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; amino acids; LC MS; fixed-charge derivatization; BMAA; chiral separation; pheromones; arctic aerosols; serum albumin adducts; benzo[a]pyrene diol epoxides; high-resolution MS; Analytical Chemistry; analytisk kemi;

    Abstract : Amino acids play vital roles in health, either in their native form or chemically modified. Some studies have linked certain non-proteinogenic amino acids to neurodegenerative diseases, such as in the case of β-methylaminoalanine (BMAA). READ MORE

  7. 5. Molecular mechanisms regulating early cone development in Norway spruce Picea abies (Karst)

    Author : Shirin Akhter; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Flower development progress through distinct phases that are controlled by complex genetic networks, which in turn are regulated by both endogenous and exogenous factors. A large number of functional studies have been conducted over the past decades to understand the genetic networks that regulate flower development in angiosperm model species. READ MORE
