Chromosome compaction involving progressive chromosome looping:

During prophase, condensin II binds DNA and extrudes large loops

In prometaphase, condensin I forms additional loops nested within the loops formed by condensin II

When dark‐treated chloroplasts are exposed to light

These light actuated ion fluxes decrease the stromal concentration of protons (the pH increases from 7 to 8) and increase that of Mg2+ by 2 to 5 mM.

GAI and RGA proteins normally act as repressors of gibberellin responses. Gibberellin acts indirectly through an unidentified signaling intermediate, which is thought to bind to the regulatory domains of the GAI and RGA Proteins.
