Question
Strigolactone is a hormone that promotes branching. During the strigolactone signal transduction cascade, in the presence of strigolactone
A)Histidine phosphor-transfer proteins shuttle into the nucleus to promote gene expression B)Cells in the immediate area of stimulation commit suicide in a hypersensitive response
C)Vascular tissues develop is a process called “strigolactone canalization”
D)Target proteins are tagged with ubiquitin and targeted to the proteosome for degradation.
E)Mobsters cut off the head of your prize race horse and leave it under your bedsheets for you to find when you wake up in the morning.
Explanation / Answer
Ans D.
Strigolactone hydrolysis by D 14 protein promotes their interaction with F box proteins. This in turn targets other proteins for tagging with ubiquitin. This then causes destruction of proteins. This process helps in controlling growth of lateral shoots.
