Summary: Adventitious roots (ARs) exhibit high phenotypic plasticity in response to environmental stimuli. This study reveals that phytochrome-interacting factors (PIFs) play a central role in darkness-induced hypocotyl adventitious root (HAR) formation by inducing the expression of genes involved in auxin biosynthesis, auxin transport, and root primordium initiation.

Summary: Transcription factors are important in regulating plant responses to environmental changes. Fluctuations in necessary resources such as light, temperature, and water lead to gene reprogramming. Phytochrome-Interacting Factors (PIFs) are key transcription factors that regulate both developmental and external stimuli-based plant growth. This review focuses on identifying PIFs in various organisms, their regulation by different proteins, and their functions in diverse developmental pathways and external stimuli-induced plant responses. Recent advances in characterizing PIFs in crops like rice, maize, and tomato are also discussed, highlighting their potential as key regulators for enhancing agronomic traits.

Summary: The AHL family transcription factor SOB3 in Arabidopsis thaliana regulates light-mediated growth, specifically hypocotyl elongation. In short day conditions, AHLs inhibit hypocotyl growth and repress PIF target genes while activating growth repressor genes. These findings suggest that AHLs affect gene expression in a time point-specific manner.

Summary: The study introduces a small red/far-red light-mediated photoswitch system called REDMAP based on the plant photoreceptor PhyA, which allows for precise spatiotemporal control of biological activities in animals. This system demonstrates dynamic control of endogenous cascades and epigenetic remodeling, with potential applications in therapy.

Summary: In this study, a dehydration-inducible PIF gene MfPIF8 was isolated and characterized from the woody resurrection plant Myrothamnus flabellifolia. Heterologous expression of MfPIF8 in Arabidopsis enhanced tolerance to drought and salinity stresses, suggesting its role in abiotic stress response. The overexpression of MfPIF8 also led to increased chlorophyll content and improved osmotic adjustment and reactive oxygen species scavenging abilities.

Summary: The interaction between phyB and FIN219/JAR1 plays a crucial role in regulating seedling development in Arabidopsis. PhyB acts as the primary photoreceptor for shade light and modulates JA signaling through FIN219. However, the molecular mechanisms underlying this interaction are still unclear.

Summary: The rapid growth of peach tree branches affects light penetration and air ventilation in orchards, leading to lower fruit quality and increased risk of diseases and insects. This study identified PpPIF8 as an interacting protein with PpDELLA2, which plays a role in repressing shoot growth. Overexpression of PpPIF8 promotes plant height and branch numbers in Arabidopsis and enhances hypocotyl elongation under weak light intensity. PpPIF4 and PpPIF8 are significantly induced by weak light. Phylogenetic analysis suggests two groups of PIFs with different evolutionary origins. These findings provide a foundation for further research on the inhibition of shoot growth by PpDELLA2 through protein interaction with PpPIF8 in peach.

Summary: This study identified six pepper PIF genes using bioinformatics methods and revealed their basic characteristics through phylogenetic and motif analysis. It was found that CaPIF8 plays a key role in cold and salt tolerance of pepper, showing different regulatory roles in response to cold and salt stress. These findings enrich our understanding of the biological roles of PIFs in plants.

Summary: The role of light in seed germination differs among plants. In Arabidopsis, light is required to initiate germination, while in Aethionema arabicum, white light inhibits germination. This study identified a mutant, koy-1, in A. arabicum that lost light inhibition of germination due to a mutation in the HEME OXYGENASE 1 gene, a key enzyme in the biosynthesis of the phytochrome chromophore.

Summary: Light regulates the function of PIFs in plant growth and yield, including their role in architecture, stress tolerance, and cell division elongation. Different crops have overlapping but distinct PIF functions. Therefore, understanding the molecular mechanisms of PIFs in plant development is crucial for improving crop productivity.

Summary: The study found that the coherence of far-red light influences the functional activity of plants, particularly when the cell fits completely in the coherence volume of the light wave field, resulting in the greatest photoinduced effect. The correlation properties of radiation also affect photoregulatory processes.

Summary: The study found a close genetic link between the growth responses of Arabidopsis thaliana stems to warmth and shade, which is also closely related to PIF4 levels; both cues enhanced the expression of growth-related genes, but only warmth promoted the expression of heat-related genes; an increase in temperature significantly increased the amount of light needed for carbon balance.

Summary: HFR1 regulates the balance between growth and defense during shade avoidance syndrome by repressing shade-induced auxin and ethylene-related genes while inducing shade-repressed defense-related genes. HFR1 acts as a negative regulator of SAS by controlling the expression of relevant genes under shade treatment.

Summary: MicroProteins such as miP1a delay floral transition in Arabidopsis by forming a complex with CO and TOPLESS. The mechanism involves JMJ14, histone H3K4 demethylase, which is required for miP1a function by regulating gene expression and chromatin modification. This study suggests a repressive complex operates in the shoot apical meristem to maintain an undifferentiated state until signals induce floral meristem formation.
