Fig. 1From: Extensive nuclear reprogramming and endoreduplication in mature leaf during floral inductionFloral transition induced by a SD-LD switch in A. thaliana. a Col-0 plants were grown in SD for 4 weeks, kept in SD (upper row) or transferred in LD (bottom row) conditions. Day before transfer (dbt), day without transfer (dwt), day after transfer (dat). Scale bars, 1 cm. b Expression of key flowering time genes. Experimental values are mean ± SEM. c Schema with developmental events. The CO and FT expression peaks are indicated, whereas the AP1 expression initiation was considered as the upper limit of the floral transition (diamonds). T0, day of transfer in LD. d Area measurement of the third and fourth rosette leaves. SD conditions (continuous line), transfer in LD (dash line). Experimental values are mean ± SEMBack to article page
