According to the current hypothesis, the gradient in phototropin phosphorylation induces the movement of auxin to the shaded side of the coleoptile. Once the auxin reaches the shaded side of the tip, it is transported basipetally to the elongation zone, where it stimulates cell elongation. The acceleration of growth on the shaded side and the slowing of growth on the illuminated side (differential growth) give rise to the curvature toward light.

Bax or Bak oligomers leads to the release of SMAC/DIABLOs, from the mitochondrial IMS which binds to XIAP in the cytosol & blocking XIAP from binding to caspases.

For the generation of transgenic plant in crop improvement, one important regulatory gene ‘X’ was overexpressed in a crop plant. Out of 30 transgenic rice plants generated, 22 showed high levels of gene ‘X’ expression. However, rest 8 lines displayed low level of expression. One explanation of such observation may be: 

Suppression effect of the transgene 

Knock down effect of gene X 

Gene silencing effect 

Co-suppression effect of transgene
