Development in Norway Spruce, Picea abies'
A pulse-treatment of embryos of Picea abies (L.) Karst with cytokinin efficiently and reproducibly induces the coordinate de novo formation of bud primordia from subepidermal cells. The cytokinin treatment also affects the germinative development of the embryo; chloroplast maturation is delayed, and cell elongation is completely suppressed. We have analyzed the protein patterns in developing sp...

متن کاملCell Wall-Bound Phenolics from Norway Spruce (Picea abies) Needles
Secondary products, such as phenolics, accumulate predominantly in the form of hydrophilic conjugates in the vacuoles (intraprotoplasmic storage) of plants [1—3]. Also there are many reports on their extraprotoplasmic location, e.g. as exudates [4] or cell wall components. The latter include the polymer lignin [5], as well as monomeric hydrolyzable phenolics, which are mainly hydroxycinnamic ac...
متن کاملSuperoxide Dismutase Activity in Needles of Norwegian Spruce Trees (Picea abies L.).
The activity of superoxide dismutase was investigated in needles of spruce trees. To obtain maximum activity, needles were homogenized in the presence of Triton X-100 and polyvinylpyrrolidone. Superoxide dismutase activity was measured in dialyzed extracts with a modified epinephrine assay (HP Misra, I Fridovich [1972] J Biol Chem 247: 3170-3175) at pH 10.2. The extracts contained 70 to 120 uni...
متن کاملConserved Function of Core Clock Proteins in the Gymnosperm Norway Spruce (Picea abies L. Karst)
From studies of the circadian clock in the plant model species Arabidopsis (Arabidopsis thaliana), a number of important properties and components have emerged. These include the genes CIRCADIAN CLOCK ASSOCIATED 1 (CCA1), GIGANTEA (GI), ZEITLUPE (ZTL) and TIMING OF CAB EXPRESSION 1 (TOC1 also known as PSEUDO-RESPONSE REGULATOR 1 (PRR1)) that via gene expression feedback loops participate in the...
