Table I.
Inflorescence phenotypes of aca T-DNA mutants and transgenic lines
Values given are averages of measurements from 6 to 10 individual plants. Values in parentheses are ses of the means. Plants were grown under a 16-h photoperiod of fluorescent light. Internode lengths, total inflorescence lengths, and number of secondary inflorescences were measured on day 45 for the Ws lines and on day 50 for the No-0 lines. The No-0 aca8-2, aca9-1, and aca10-1 lines were BCII F3 plants derived from representative homozygous BCII F2 parents. The cif1-1 lines containing chimeric transgenes were T3 plants derived from representative homozygous T2 parents. *, P < 0.05; **, P < 0.0001 (Student's t test).
