Expression of GL1, GL3, GIS, GIS2, and ZFP8 in DELLA-defective ga1-3 mutants. Transcript levels of the different trichome initiation regulatory genes in various DELLA mutants were measured by real-time PCR. Values represent the average and sd from three measurements and are relative to the expression of the UBQ10 gene. Gene expression was measured in young developing inflorescences. Mutants presenting a significant change in gene expression are indicated by an arrow. gai*, gai-t6; rga*, rga-t2; Ler, Landsberg erecta ecotype control.
