Plant hormones: Dissecting the gibberellin response pathway
Plant development is amazingly plastic — for example, identical pine seeds can give rise to a majestic tree in a forest or a scraggly bush on a rocky cliff. How is plant growth and development regulated so as to be capable of achieving such dramatically different endpoints? One factor that has emerged as a key regulator of plant form is gibberellin (GA; see Figure 1 inset for the chemical struc...
متن کاملBiosynthesis of Plant Hormones by Microorganisms
Higher plants are exposed to a multitude of fungi and bacteria, which are present in the surrounding phyllosphere and rhizosphere and which may also grow inside the shoot and the root. Compounds, known to act as hormones in higher plants, are produced by many of these microorganisms and are often functionalized in “friendly” or “hostile” interaction with the respective host plant. A large numbe...
متن کاملEffects of shoot-applied gibberellin/gibberellin-biosynthesis inhibitors on root growth and expression of gibberellin biosynthesis genes in Arabidopsis thaliana
To elucidate the involvement of gibberellin (GA) in the growth regulation of Arabidopsis roots, effects of shoot-applied GA and GA-biosynthesis inhibitors on the root were examined. Applying GA to the shoot of Arabidopsis slightly enhanced the primary root elongation. Treating shoots with uniconazole, a GA biosynthesis inhibitor, also resulted in enhancement of primary root elongation, while sh...
متن کاملGenetic analysis of gibberellin biosynthesis.
In his studies on the nature of inheritance, Gregor Mendel (1866) examined seven pairs of traits in pea, including one he called “difference in the length of the stem” (Fig. 1). The tall character dominated the dwarf, segregating three tall to one dwarf. When Mendel’s work was rediscovered at the beginning of this century, Orland White introduced the term Le, for Length, to represent this trait...
متن کاملSites of gibberellin biosynthesis in pea seedlings.
Potential sites of gibberellin biosynthesis in 10-day-old ;Alaska' pea (Pisum sativum L.) seedlings were investigated using a cell-free ezyme system capable of incorporating [(14)C]-mevalonic acid into ent-kaurene. In peas, ent-kaurene is assumed to be a committed intermediate in the gibberellin biosynthetic pathway. Comparative results from enzyme assays using extracts from shoot tips, leaf bl...
