Název v původním jazyce
Auxin regulation of LOGs in shoot apical meristem.
Popis výsledku v původním jazyce
In plants, new organs are periodically initiated in a regular pattern called phyllotaxis. Self-organization of phyllotaxis is driven by spatio-temporal distribution of the hormone auxin and the temporal robustness of the pattern is also under the influence of another hormone, cytokinin. We have found using expression analysis that several cytokinin biosynthetic enzymes from the LONELY GUY family (LOGs) are potentially upregulated by auxin in Arabidopsis. We have analyzed the expression of all LOGs in the shoot apical meristem and identified several LOGs differentially expressed in the meristem. Additionally, we have analyzed phyllotaxis of single log mutants to test their contribution to shoot apical meristem patterning. We have found mutants showing higher variability in divergence angles between successive organs, suggesting an involvement of cytokinin also in the robustness of angle specification in phyllotaxis.
