Phytochrome-interacting factors (PIFs) play a crucial role in regulating plant growth and development. However, studies on soybean PIFs are limited. Here, we identified 22 GmPIF genes from the soybean genome and classified the GmPIF proteins into 13 subfamilies based on amino acid sequence homology, secondary and tertiary structures, protein structure, and conserved motifs.

Cold stress severely impacts the quality and yield of grapevine (Vitis L.). In this study, we extend our previous work to elucidate the role and regulatory mechanisms of Vitis amurensis MYB transcription factor 4a (VaMYB4a) in grapevine's response to cold stress.

Barley traits that determine grain number are established between jointing and flowering. The timing of flowering is critical for adaptation and yield as it affects the fertility of both the main shoot and tiller spikes. The Photoperiod-H1 (PPD-H1) gene controls flowering time and impacts spike fertility and yield in barley; however, it is not known if these effects are truly pleiotropic or indirect.

Light serves as an energy source for cell division and expansion during fruit development. Cell expansion significantly influences fruit size and is closely linked to endoreduplication, a unique cell cycle variation characterized by DNA replication without cytokinesis. Paradoxically, under conditions of ample photosynthates, light signaling suppresses cell expansion.

It is known that red light irradiation enhances the biosynthesis of (E)-β-caryophyllene in plants. However, the underlying mechanism connecting red light to (E)-β-caryophyllene biosynthesis remains elusive. This study reveals a molecular cascade involving the phyB-PIF4-MYC2 module, which regulates (E)-β-caryophyllene biosynthesis in response to the red light signal in Arabidopsis thaliana.
