From: SlPIN1 regulates auxin efflux to affect flower abscission process
In situ hybridization of SlPIN1 in the tomato pedicel during abscission. Images of longitudinal sections of the distal part (a,d,g,j), AZ (b,e,h,k) and proximal part (c,f,i,l) 0 h (a-c), 1 h (d–f), 2 h (g–i) and 4 h (j–l) after flower removal and detection of SIPIN1 using an antisense probe. Sections detected using a sense probe of SlPIN1 (m–o) were used as controls. The insert in d shows a magnified image of the region shown in the white box. Tissues are indicated by white letters. C, cortex, V, vascular bundle, P, pith, AL, abscission layers. Scale bar = 100 μm.
