Alteration of developmental phenotype in transgenic A rabidopsis caused by constitutive expression of Rad2b‐Leu, but not Rad2b‐Pro, in transgenic lines

Transgene	Number of primary transformed lines	Plants with no obvious defects*	Plants with moderate defects†	Plants with severe defects‡
Rad2b‐Pro	35	35	0	0
Rad2b‐Leu	36	16	9	11

See Fig. 2 for examples of plants expressing no (*Tier I), moderate (†Tier II) or severe (‡Tier III) Rad2b‐Leu‐induced effects on phenotype.
