TOP1α regulates FLOWERING LOCUS C expression by coupling histone modification and transcription machinery.
Development (Cambridge, England)
Zhong P,Li J,Luo L,Zhao Z,Tian Z
The key steps of transcription are coupled with the opening of the DNA helical structure and establishment of active chromatin to facilitate the movement of the transcription machinery. Type I topoisomerases cleave one DNA strand and relax the supercoiled structure of transcribed templates. How topoisomerase-mediated DNA topological changes promote transcription and establish a permissive histone modification for transcription elongation is largely unknown. Here we show that TOPOISOMERASE 1&alph

Seeds germination or dormancy is strictly controlled by endogenous phytohormone signal and environment cues. High temperature (HT) suppresses seeds germination or triggers seeds dormancy but underlying mechanism by which HT mediates seeds germination thermoinhibition needs more investigating. SOM is reported as the critical factor negatively controls light-irradiation seeds germination by altering Abscisic acid (ABA) and gibberellin acid (GA) biosynthesis. Here we found that HT accelerates SOM e

PRC2 recruitment and H3K27me3 deposition at FLC require FCA binding of COOLAIR.
Science advances
Tian Y,Zheng H,Zhang F,Wang S,Ji X,Xu C,He Y,Ding Y
The cold-induced antisense transcript COOLAIR represses FLOWERING LOCUS C (FLC) transcription with increased H3K27me3 and decreased H3K36me3 levels in response to cold temperatures. However, the molecular connection between COOLAIR and histone modification factors in the absence of cold treatment remains unclear. We report that the RNA binding protein FCA interacts with the PRC2 subunit CURLY LEAF (CLF) and binds nascent COOLAIR transcripts to allow deposition of H3K27me3 at FLC. Loss of COOLAIR

MLK1 and MLK2 Coordinate RGA and CCA1 Activity to Regulate Hypocotyl Elongation in Arabidopsis thaliana.

Zheng H,Zhang F,Wang S,Su Y,Ji X,Jiang P,Chen R,Hou S,Ding Y
Gibberellins (GAs) modulate diverse developmental processes throughout the plant life cycle. However the interaction between GAs and the circadian rhythm remains unclear. Here we report that MUT9p-LIKE KINASE1 (MLK1) and MLK2 mediate the interaction between GAs and the circadian clock to regulate hypocotyl elongation in DELLA proteins function as master growth repressors that integrate phytohormone signaling and environmental pathways in plant development. MLK1 and MLK2 interact with the DELLA

The COMPASS-Like Complex Promotes Flowering and Panicle Branching in Rice.
Plant physiology
Jiang P,Wang S,Jiang H,Cheng B,Wu K,Ding Y
Flowering time (heading date) and panicle branch number are important agronomic traits that determine yield in rice (Oryza sativa). The activation of flowering requires histone methylation, but the roles of trimethylation of Lys 4 of histone 3 (H3K4me3) in modulating heading date and panicle development are unclear. Here, we showed that the COMPASS-like complex promotes flowering and panicle branching. The rice (Oryza sativa) WD40 protein OsWDR5a interacts with the TRITHORAX-like protein OsTrx1/

Fluorescence-based ATG8 sensors monitor localization and function of LC3/GABARAP proteins.
The EMBO journal
Stolz A,Putyrski M,Kutle I,Huber J,Wang C,Major V,Sidhu SS,Youle RJ,Rogov VV,Dötsch V,Ernst A,Dikic I
Autophagy is a cellular surveillance pathway that balances metabolic and energy resources and transports specific cargos including damaged mitochondria other broken organelles or pathogens for degradation to the lysosome. Central components of autophagosomal biogenesis are six members of the LC3 and GABARAP family of ubiquitin-like proteins (mATG8s). We used phage display to isolate peptides that possess LIR (LC3-interacting region) properties and are selective for individual mATG8 isoforms. Se

Phosphorylation of Histone H2A at Serine 95: A Plant-Specific Mark Involved in Flowering Time Regulation and H2A.Z Deposition.
The Plant cell
Su Y,Wang S,Zhang F,Zheng H,Liu Y,Huang T,Ding Y
Phosphorylation of histone H3 affects transcription chromatin condensation and chromosome segregation. However the role of phosphorylation of histone H2A remains unclear. Here we found that MUT9P-LIKE-KINASE (MLK4) phosphorylates histone H2A on serine 95 a plant-specific modification in the histone core domain. Mutations in caused late flowering under long-day conditions but no notable phenotype under short days. MLK4 interacts with CIRCADIAN CLOCK ASSOCIATED1 (CCA1) which allows MLK4 to bind

A quartet of PIF bHLH factors provides a transcriptionally centered signaling hub that regulates seedling morphogenesis through differential expression-patterning of shared target genes in Arabidopsis.
PLoS genetics
Zhang Y,Mayba O,Pfeiffer A,Shi H,Tepperman JM,Speed TP,Quail PH
Dark-grown seedlings exhibit skotomorphogenic development. Genetic and molecular evidence indicates that a quartet of Arabidopsis Phytochrome (phy)-Interacting bHLH Factors (PIF1, 3, 4, and 5) are critically necessary to maintaining this developmental state and that light activation of phy induces a switch to photomorphogenic development by inducing rapid degradation of the PIFs. Here, using integrated ChIP-seq and RNA-seq analyses, we have identified genes that are direct targets of PIF3 transc
