TL;DR: Highly integrated maps of the epigenome, mRNA, and small RNA transcriptomes of two rice subspecies and their reciprocal hybrids reveal that gene activity was correlated with DNA methylation and both active and repressive histone modifications in transcribed regions.

TL;DR: A cross-talk mechanism is reported that enables a receptor-like kinase, FERONIA (FER), a positive regulator of auxin-promoted growth, to suppress the abscisic acid (ABA) response through activation of ABI2, a negative regulator of ABA signaling.

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: It is demonstrated that UV-B triggers the physical and functional disassociation of the COP1–SPA core complex from CUL4–DDB1 and the formation of a unique complex(es) containing theUV-B receptor UV RESISTANCE LOCUS 8 (UVR8) and sheds light on the mechanism of COP1’s promotive action in UV- B–induced photomorphogenesis.

TL;DR: It is concluded that OsNCED3 mediates seed dormancy, plant growth, abiotic stress tolerance, and leaf senescence by regulating ABA biosynthesis in rice; and may provide a new strategy for improving the quality of crop.
