Cytokinin pathway mediates APETALA1 function in the establishment of determinate floral meristems in Arabidopsis.
In angiosperms, after the floral transition, the inflorescence meristem produces floral meristems (FMs). Determinate growth of FMs produces flowers of a particular size and form. This determinate growth requires specification of floral organs and termination of stem-cell divisions. Establishment of the FM and specification of outer whorl organs (sepals and petals) requires the floral homeotic g...

translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...
15 صفحه اولPrenylation of the floral transcription factor APETALA1 modulates its function.
The Arabidopsis MADS box transcription factor APETALA1 (AP1) was identified as a substrate for farnesyltransferase and shown to be farnesylated efficiently both in vitro and in vivo. AP1 regulates the transition from inflorescence shoot to floral meristems and the development of sepals and petals. AP1 fused to green fluorescent protein (GFP) retained transcription factor activity and directed t...
متن کاملArabidopsis cytokinin signaling pathway.
Cytokinins are essential plant hormones that control cell division, shoot meristem initiation, leaf and root differentiation, vasculature patterning, chloroplast biogenesis, photomorphogenesis, fertility, seed development, senescence, and stress tolerance. The Arabidopsis cytokinin signal transduction pathway involves hybrid histidine protein kinases [AHK2, AHK3, and AHK4 (also known as CRE1or ...
