Dataset link Detection of genes acting downsteram of ectopically expressed TCP/CYC2 transcription factors in Arabidopsis thaliana

Experimental Protocol

The coding sequences of the TCP/CYC2 transcription factors IaTCP1, TCP1 and CYC were cloned into the pBAR vector (GenBank: AJ251014), resulting in the constructs #0522 (IaTCP1), #0569 (TCP1) and #0577 (CYC). In pBAR, all genes are under the control of the CaMV35S-promoter. Arabidopsis plants were transformed (via floral dip) with respective constructs and also with the empty vector (pBar). Transgenic plants (T1) with petal size deviation from the control (plants transformed with the empty vector and wild type) were selfed and resulting T2 lines with petal size deviations from control were selected. Inflorescence buds from secondary inflorescences were harvested from transgenic T2 plants that formed smaller (#0255 or #0569) or larger (#0577) petals in the main inflorescence. Total RNA was isolated and sent to the Integrated Functional Genomics Service at the University of Münster, Germany, which carried out probe preparation, hybridization and statistical analysis of the data. Differential gene expression was always determined from a comparison of gene expression from #0522, #0569 and #0577, respectively, against the control (#pBar; inflorescence gene expression in plants transformed with an empty vector).
