^aHeterozygous cki1-5/+ plants were transformed with different constructs.

^bAll transgenes were placed under the control of the CKI1 promoter and were cloned into the binary vector pER8 (Zuo et al., 2000) that carried a hygromycin selectable marker gene. “Empty vector” refers to the use of pER8 in the transformation. “–” Denotes self-pollinated nontransgenic plants.

^c“Tested” refers to the tested T1 transgenic lines that were resistant to hygromycin and carried a cki1-5 mutation. For nontransgenic plants, the number refers to the analyzed progeny obtained from self-pollinated cki1-5/+ plants that carried a cki1-5 mutation.

^d“cki1-5/−” refers to homozygous lines (transgenics) or families (self-pollinated) that were obtained from the tested populations by PCR genotyping and phenotypic analysis.
