#Unit 6. System Physiology – Plant

Reversal of etiolation

Etiolated plants are those that have been grown in the dark, light stimulates increased [cytokinin] which stimulates cell division and greening.

increases [GA] which presumably stimulates IAA oxidase production to get rid of excess IAA that causes the long spindly growth.

IAA stimulates ethylene synthesis which maintains the apical hook, treating the apical hook with red light + ethylene maintains the hook.

#Unit 3. Fundamental Processes

In the nucleus, the cap is recognized and bound by the cap binding CBP20/80 heterodimer. This binding event stimulates splicing of the first intron and, via a direct interaction with the mRNA export machinery (TREX complex), facilitates mRNA export out of the nucleus. Once reaching the cytoplasm, a different set of proteins (eIF4F) binds the cap to initiate translation of the mRNA in the cytoplasm.
