Auxin Dynamics during Capsella Fruit Development in Wild-Type and the crind Mutant

(A–E) SEM images of fruits from CrWT at developmental stages 11 (A), 12 (B), 13 (C), and 14 (D) and from crind-1^ge at stage 14 (E).

(F–J) Auxin signaling visualized by pDR5v2:GUS in CrWT fruit of developmental stages 11 (F), 12 (G), 13 (H), and 14 (I) and in the crind-1^ge mutant at stage 14 (J).

(K–N) Expression analysis by qRT-PCR of CrIAA5 (K), CrGH3.3 (L), CrSAUR16 (M), and CrACTIN7 (N) in the fruit shoulders of WT and crind-1^ge at stage 14. Error bars represent SD of three biological replicates.

(O and P) Measurements of IPA (O) and IAA (P) in fruit shoulders of WT and crind-1^ge stage-14 fruits. Error bars represent SD of three biological replicates.

Scale bars represent 150 μm (A–J). ^∗∗p < 0.01 (Student’s t test) in (K–P).
