Description
| - To maintain proper meristem function, cell division and differentiation must be coordinately regulated in distinct subdomains of the meristem. Although a number of regulators necessary for the correct organization of the shoot apical meristem (SAM) have been identified, it is still largely unknown how their function is integrated with the cell cycle machinery to translate domain identity into correct cellular behavior. We show here that the cyclin-dependent kinases CDKB2;1 and CDKB2; 2 are required both for normal cell cycle progression and for meristem organization. Consistently, the CDKB2 genes are highly expressed in the SAM in a cell cycle-dependent fashion, and disruption of CDKB2 function leads to severe meristematic defects. In addition, strong alterations in hormone signaling both at the level of active hormones and with respect to transcriptional and physiological outputs were observed in plants with disturbed CDKB2 activity.

- Ukázalo se, že cyklin-dependentní kinázy CDKB2;1 a CDKB2;2 jsou potřebné pro normální průběh buněčného cyklu a pro uspořádání meristému. CDKB2 geny jsou vysoce exprimovány v nadzemním apikálním meristému (SAM) a přerušení funkce CDKB2 vede k těžkým meristematickým defektům. Navíc, silné změny v hormonálním signalingu byly pozorovány v rostlinách s narušenou CDKB2 aktivitou na úrovni aktivních hormonů a s ohledem na transkripční i fyziologické výstupy. (cs)
