Trehalose and Tre6P content in maize ramosa3 inflorescence primordia. Ear inflorescence primordia (1-4 mm in length) were harvested from 9 to 10-week-old plants of the ramosa3 (ra3) mutant and wild type B73 (RA3) maize plants. Trehalose (A) was measured fluorometrically and Tre6P (B) was measured by LC-MS/MS. The trehalose:Tre6P ratio (C) was calculated for each individual sample. Data are mean ± SD (n = 4).
