TL;DR: Findings show that the APG8/12 conjugation pathways have been conserved in plants and may have important roles in autophagic recycling, especially during situations that require substantial nitrogen and carbon mobilization.

TL;DR: The reverse genetic analysis of two F-box proteins, EBF1 and -2, that work coordinately in SCF complexes to repress ethylene action show that the SCF(EBF1/EBF2)-dependent ubiquitination and subsequent removal of EIN3 is critical not only for proper ethylene signaling but also for growth in plants.

TL;DR: Both their presence in many diverse bacteria and their simplified assembly with biliverdin suggest that BphPs are the progenitors of phytochrome-type photoreceptors.

TL;DR: Through their coordinated control of EIN3/EIL1 levels, EBF1 and EBF2 fine-tune ethylene responses by repressing signaling in the absence of the hormone, dampening signaling at high hormone concentrations, and promoting a more rapid recovery after ethylene levels dissipate.

TL;DR: Phy-type sequences were also discovered in the actinobacterium Kineococcus radiotolerans and collections of microorganisms obtained from marine and extremely acidic environments, thus expanding further the range of these photoreceptors.
