^aConstruct used for transformation. Expression was under the control of the 35S CaMV promoter.  ^bExpression in the meristematic region. No or very low expression was seen in cotyledons.  ^cExpression in cotyledon lamina (more than 50% of surface).  ^dChange in expression pattern after H₂O₂ treatment. Two-tailed P values were calculated using Fisher’s exact test.
