TL;DR: Results reveal for the first time a wavelength-specific mechanism by which a cryptochrome photoreceptor mediates light regulation of protein degradation to modulate developmental timing in Arabidopsis.

TL;DR: It is reported here that Arabidopsis blue-light receptor cryptochrome 1 (CRY1) undergoes blue- light-dependent interaction with the COP1-interacting protein SPA1 (SUPPRESSOR of PHYTOCHROME A), consistent with a hypothesis that photoexcited CRY1 interacts with SPA2 to modulate COP1 activity and plant development.

TL;DR: ABI2 can directly interact and dephosphorylate FER, providing a feedback mechanism for ABA activation of FER and for cross-talk between ABA and peptide hormone RALF in the control of plant growth and responses to stress signals.

TL;DR: The results show that CRY2 mediates blue light inhibition of hypocotyl elongation and photoperiodic promotion of floral initiation in the nucleus, and it is demonstrated that a photoreceptor can complete its posttranslational life cycle inside the nucleus.

TL;DR: Surprisingly, no significant change in the GA4 content was detected in the whole shoot samples of the wild-type or cry1cry2 seedlings grown in the dark or continuous blue light, suggesting that cryptochromes may also regulate GA responsiveness and/or trigger cell- or tissue-specific changes of the level of bioactive GAs.
