dcterms:description
The co-ordination of cell wall synthesis with plant cell expansion is an important topic of contemporary plant biology research. In studies of cell wall synthesis pathways, cellulose synthesis inhibitors are broadly used. It is demonstrated here that ancymidol, known as a plant growth retardant primarily affecting gibberellin biosynthesis, is also capable of inhibiting cellulose synthesis. Its ability to inhibit cellulose synthesis is not related to its anti-gibberellin action and possesses some unique features never previously observed when conventional cellulose synthesis inhibitors were used. It is suggested that ancymidol targets the cell wall synthesis pathway at a regulatory step where cell wall synthesis and cell expansion are coupled. The elucidation of the ancymidol target in plant cells could potentially contribute to our understanding of cell wall synthesis and cell expansion control.

Koordinace biosyntézy buněčné stěny a buněčné expanze je důležitým tématem současného výzkumu rostlin. Při něm jsou často využívány inhibitory syntézy celulózy. V této práci ukazujeme, že známý růstový retardant ancymidol ovlivňující biosyntézu giberelinů je též schopen inhibovat syntézu celulózy. Tato schopnost ancymidolu nemá spojitost s jeho anti-giberelinovým účinkem a vykazuje některé znaky, které u konvenčních inhibitorů biosyntézy nebyly pozorovány. Naše výsledky naznačují, že ancymidol pravděpodobně zasahuje regulační bod propojující syntézu buněčné stěny a buněčnou expanzi. Objasnění mechanismu účinku ancymidolu na syntézu celulózy by mohlo přispět k pochopení procesů syntézy buněčné stěny a kontroly buněčné expanze.
