| Description
| - Architektura rostlin je dána postupným formováním orgánů z meristémů. Významnou roli při formování vrcholového meristému stonku rostliny hrají homeoboxové geny KNOXI. Aktivace tří různých KNOXI proteinů vede k rychlému nárůstu hladiny mRNA isopentenyltransferasy 7 (AtIPT7), podílející se na biosyntéze cytokininů. Bylo prokázáno, že v důsledku aktivace AtIPT7 dojde k nárůstu hladin cytokininů a potažmo k aktivaci ARR5, cytokininového odezvového faktoru. Lze tedy shrnout, že tvorba vrcholového meristému stonku je regulována KNOXI proteiny prostřednictvím aktivace biosyntézy cytokininů. (cs)
- Plant architecture is shaped through the continuous formation of organs by meristems [1]. Class I KNOTTED1-like homeobox (KNOXI) genes are expressed in the shoot apical meristem (SAM) and are required for SAM maintenance [2-6]. KNOXI proteins and cytokinin, a plant hormone intimately associated with the regulation of cell division [7, 8], share overlapping roles, such as meristem maintenance and repression of senescence [2, 9-11], but their mechanistic and hierarchical relationship have yet to be defined. Here, we show that activation of three different KNOXI proteins using an inducible system resulted in a rapid increase in mRNA levels of the cytokinin biosynthesis gene isopentenyl transferase 7 (AtlPT7) and in the activation of ARR5, a cytokinin response factor. We further demonstrate a rapid and dramatic increase in cytokinin levels following activation of the KNOXI protein SHOOT MERISTEMLESS (STM).
