Correlation of auxin level with first-order rosette branch number.

<p>(A) Morphology of 35-day-old plants of <i>adp1</i>-D, Pro35S:<i>YUCCA1</i> and double mutants of <i>adp1</i>-D Pro35S:<i>YUCCA1</i>. Bar = 1 cm. (B) Quantitative analysis of first-order rosette branch from 2-month-old plants of <i>adp1</i>-D, Pro35S:<i>YUCCA1</i> and double mutants of <i>adp1</i>-D Pro35S:<i>YUCCA1</i>. Thirty plants of each genotype were measured. The error bars represent the SD. (C) Quantitative analysis of emergence rate of rosette leaves in <i>adp1</i>-D, Pro35S:<i>YUCCA1</i> and double mutants of <i>adp1</i>-D Pro35S:<i>YUCCA1</i>. Thirty plants of each genotype were measured. The error bars represent the SD. (D) to (I) Morphology of crossed lines between <i>adp1-</i>D and Pro<i>ADP1</i>:<i>iaaM</i> transgenic lines at 25 days after germination (D to F) and two months after germination (G to I). The axillary buds developed much slower in the crossed lines compared with <i>adp1-</i>D, indicated by arrowheads from (D) to (F). At maturity, the crossed lines with stronger <i>iaaM</i> expression level even showed terminated flowers, as indicated by the inserted frame in (I). (J) Expression quantity of <i>iaaM</i> in the wild type and the crossed lines shown in (D) to (I) analyzed by real-time-quantitative PCR (qPCR). (K) First-order rosette branch number of the wild type and the crossed lines shown in (D) to (I). (L) Emergence rate of rosette leaves in the wild type and the crossed lines shown in (D) to (I).
