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 کاملMetabolite profiling reveals clear metabolic changes during somatic embryo development of Norway spruce (Picea abies).
Progress on industrial-scale propagation of conifers by somatic embryogenesis has been hampered by the differences in developmental capabilities between cell lines, which are limiting the capture of genetic gains from breeding programs. In this study, we investigated the metabolic events occurring during somatic embryo development in Norway spruce to establish a better understanding of the fund...
متن کاملA possible biochemical basis for fructose-induced inhibition of embryo development in Norway spruce (Picea abies).
Sugars play an important role in various physiological processes during plant growth and development; however, the developmental roles and regulatory functions of hexoses other than glucose are still largely unclear. Recent studies suggest that blocked embryo development in Norway spruce (Picea abies (L.) Karst) is associated with accumulation of fructose. In the present study, the potential bi...
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...
