Figure 1. GATA2 is a positive regulator of photomorphogenesis.

Figure 1

(A), BR treatment reduces GATA2 RNA level. Arabidopsis seedlings grown in the dark (WD) or light (WL) for five days were treated with mock solution or 100 nM 24-epibrassinolide (BR) for 3 hours and the expression of GATA2 was analyzed by qRT-PCR. (B) qRT-PCR analysis of GATA2 and GATA4 RNA levels in 5-day-old dark-grown wild type (Col-0), det2, bri1-116, and bri1-116 bzr1-1D. (C) Dark-grown phenotypes of three GATA-ox lines. Lower panels show qRT-PCR of GATA2 expression (see also Figure S1P, S1R). (D) Phenotypes of light-grown (first on left) or dark-grown seedlings of wild type (Col-0), BR mutants and a representative GATA2-ox transgenic line 6. (E) Phenotypes of antisense (AS) or artificial-microRNA (AM) transgenic Arabidopsis seedlings with reduced levels of GATA2 and GATA4 (see also Figure S2A for quantitation data). Lower panel shows qRT-PCR analysis of GATA2 and GATA4 in these transgenic seedlings. All error bars are standard deviation (SD).
