Summary: This study identifies and characterizes a type of Trx gene called TaTrxh9 in wheat. TaTrxh9 is involved in the regulation of heading time in wheat, and its expression is correlated with plant development. These findings provide new insights into the biological function of TaTrxh9 and offer potential for molecular breeding targeting early heading in wheat.

Summary: Histone-modifying proteins, such as KDM5, are crucial for precise regulation of transcriptional programs during development. In this study, the essential roles of the Drosophila Kdm5 ortholog were examined, revealing its involvement in the regulation of mitochondrial gene expression and morphology in the larval neuroendocrine prothoracic gland.

Summary: This paper investigates the mechanisms of wheat flowering under cold and age conditions. The study finds that the microRNA miR172 and its target gene APETALA2-like (AP2L) play important roles in regulating the flowering process, while the induction of the vernalization gene VERNALIZATION1 (VRN1) inhibits the expression of AP2L and promotes flowering. Additionally, the levels of miR172 and AP2L genes modulate the flowering response to different vernalization treatments in winter wheat.

Summary: Wheat heading date is crucial for environmental adaptability and yield component regulation. RNA-Seq analysis identified thousands of differentially expressed genes associated with flowering time. Co-expression networks of key flowering time genes were established, and a potential candidate gene was discovered for further study on the regulatory mechanism of wheat heading date.

Summary: Competition for intracellular resources induces coupling between co-expressed genes, affecting the reliability of gene circuits. We found that miRNA-mediated target downregulation leads to upregulation of co-expressed genes, and using miRNAs-based loops can stabilize genes against burden. Our study provides insights into the hidden regulatory interaction of miRNA-based synthetic networks, and can help design genetic circuits that modulate transgene co-expression by tuning resource availability.

Summary: A minor-effect QTL, Qhd.2AS, that affects heading date in wheat was mapped to a genomic interval of 1.70-Mb on 2AS, and the C2H2-type zinc finger protein gene TraesCS2A02G181200 is identified as the best candidate for Qhd.2AS.

Summary: The photoperiodic response is critical for plants to adjust their reproductive phase to the most favorable season. Wheat heads earlier under long days (LD) than under short days (SD) and this difference is mainly regulated by the PHOTOPERIOD1 (PPD1) gene.

Summary: Little is known about genes that regulate flowering time difference among winter wheat cultivars, but this study identified an O-linked N-acetylglucosamine (O-GlcNAc) transferase TaOGT1 that plays a crucial role in this regulation. Through map-based cloning, the authors demonstrated the significance of TaOGT1 in adapting winter wheat cultivars to future climate scenarios with global warming.

Summary: This study reveals that the nitrogen metabolism regulator NtrX directly regulates the expression of key transcription factors ctrA, gcrA, and dnaA in Sinorhizobium meliloti, thereby affecting cell division. The phosphorylation of the conserved 53rd aspartate in NtrX protein is essential for its transcription regulation.

Summary: The heavy-metal-associated isoprenylated plant protein HIPP1-V plays an important role in regulating wheat resistance to powdery mildew, with its isoprenylation critical for plasma membrane localization and interaction with E3-ligase CMPG1-V. DGEs related to ROS and SA pathways were enriched in HIPP1-V, revealing their involvement in powdery mildew resistance.

Summary: This study identified a rice ternary repressive protein complex composed of OsELF4a, OsELF3-1, and OsLUX, which plays important roles in salt tolerance and heading in rice. Loss-of-function mutants of OsEC1 showed reduced survival rate under salt stress and late heading date. Transcriptomic profiling revealed that OsEC1 regulates salt tolerance and heading by repressing OsGI, a homologue of GIGANTEA.

Summary: Anthocyanins play a crucial role in providing different visual effects to plants through various biosynthetic pathways, attracting pollinators and seed dispersers. MYB transcription factors are key regulators in anthocyanin biosynthesis, controlling the enrichment and sedimentation of anthocyanins. The study discusses the regulation of anthocyanin biosynthetic mechanisms by MYB-TFs and analyzes the role of the environment in controlling the anthocyanin biosynthesis network.
