Wild type (line FV2)	26.05 ± 3.5 (100)	102.5 ± 17.4 (100)	259.9 ± 8.2 (100)	2.16 ± 0.02 (100)

Each value is the mean ± sd obtained from three individual plants for the mutants and six individual plants for the transgenics grown on soil in a glasshouse and watered daily with the medium described by Coïc and Lesaint (1971). The values indicated in parentheses are expressed as percentages of the value in the wild type. For the plants overexpressing Gln1-3, the values are the mean of the two transgenic lines and of the corresponding null segregants.

Significantly different from the wild type at 0.05 probability level.
