Flowering of Day-Neutral Tobacco Nicotiana Tabacum L. as Influended by Transformation with CDC25
 Vojvodová, Petra
Plants are sessile organisms and so they cannot escape changes in environmental conditions. In order to optimize seed production and to ensure that flowering occurs during the appropriate season, plants have evolved a complex of regulatory pathways to control when the floral transition takes place. One group of regulatory pathways involves enviromental factors like certain photoperiod or vernalization. The second group of regulatory pathways involves the state of development and is not sensitive to environmental cues, this pathway is called autonomous pathway and plants in this group do not require a particular photoperiod or vernalization, they are called day-neutral plants. The transition of these plants from vegetative to reproductive phase depends on combination of reaching certain minimal number of nodes, inhibition effect of roots, floral signals generated by leaves and activity of the shoot apical meristem (SAM). Among early events of the transition of SAM to reproductive phase belongs an increase in the mitotic activities of the cells in SAM. Precise mechanisms of the action of the signals connected with transition of SAM to flowering have not been elucidated yet. The plants of day-neutral tobacco (Nicotiana tabacum L.) cv. Samsun were transformed with fission yeast mitotic activator coded...
