  • All constructs were expressing cDNA with exception of ZCN7g, which was a genomic fragment including exons and introns. Leaf numbers were collected from at least 10 individual plants from two independent events. Mean values and standard deviations were calculated by the analyses of variance from the Minitab statistical program. NTG, nontransgenic sibling plants; TG, transgenic plants.

  • a Means are statistically significant with P < 0.1.

  • b Means are statistically significant with P < 0.05.
