Architecture and Dynamics of the Jasmonic Acid Gene Regulatory NetworkDetailed analysis of temporal reprogramming of gene activity illuminates the complexity of the jasmonic acid (JA) gene regulatory network and pinpoints transcriptional regulators of JA responses.
Zygotic Genome Activation Occurs Shortly after Fertilization in MaizeTranscription profiles generated from maize gametes and zygotes at different stages reveal a highly dynamic zygotic genome activation pattern, providing insights into early embryo development.
Genomic Analysis of the DNA Replication Timing Program during Mitotic S Phase in Maize (Zea mays) Root TipsThe time during S phase at which different maize DNA sequences replicate reveals a complex temporal program influenced by genomic features, transcriptional activity, and chromatin structure.

Subgenome Dominance in an Interspecific Hybrid, Synthetic Allopolyploid, and a 140-Year-Old Naturally Established Neo-Allopolyploid MonkeyflowerSubgenome differences in levels of transposon methylation mirror increases in subgenome-specific expression bias observed over generations following hybridization and allopolyploidization in Mimulus.
A Specific Gibberellin 20-Oxidase Dictates the Flowering-Runnering Decision in Diploid StrawberryA gibberellin 20-oxidase plays a pivotal role in transitioning the axillary meristem to a stolon or floral shoot and hence the trade-off between vegetative propagation and fruit yield in strawberry.
Plant-Specific Histone Deacetylases HDT1/2 Regulate GIBBERELLIN 2-OXIDASE2 Expression to Control Arabidopsis Root Meristem Cell NumberHDT1 and HDT2 fine-tune GA metabolism in Arabidopsis root tips to control the switch from cell division to expansion, and in this way determine meristem cell number and regulate root growth rate.
Phosphorylation of Histone H2A at Serine 95: A Plant-Specific Mark Involved in Flowering Time Regulation and H2A.Z DepositionPhosphorylation of H2A at serine 95, a plant-specific modification in the histone core domain, is required for flowering time regulation and deposition of the histone variant H2A.Z in Arabidopsis.
The Intracellular Immune Receptor Sw-5b Confers Broad-Spectrum Resistance to Tospoviruses through Recognition of a Conserved 21-Amino Acid Viral Effector EpitopeA plant intracellular immune receptor mediates broad-spectrum resistance by recognizing a small conserved PAMP-like region within the pathogen protein.
GENERAL CONTROL NONREPRESSIBLE4 Degrades 14-3-3 and the RIN4 Complex to Regulate Stomatal Aperture with Implications on Nonhost Disease Resistance and Drought ToleranceGCN4, an AAA+-ATPase family protein, is a novel player in stomatal aperture regulation that can affect plant immunity and abiotic stress.
An InDel in the Promoter of Al-ACTIVATED MALATE TRANSPORTER9 Selected during Tomato Domestication Determines Fruit Malate Contents and Aluminum ToleranceSl-ALMT9, directly regulated by Sl-WRKY42, contributes to fruit malate accumulation both in fruit and root and enhances aluminum tolerance of tomato.
Light and Ethylene Coordinately Regulate the Phosphate Starvation Response through Transcriptional Regulation of PHOSPHATE STARVATION RESPONSE1Several transcription factors interact with each other and bind directly to the PHOSPHATE STARVATION RESPONSE1 promoter to coordinately regulate its expression in response to light and ethylene.
The Arabidopsis Leucine-Rich Repeat Receptor Kinase BIR3 Negatively Regulates BAK1 Receptor Complex Formation and Stabilizes BAK1The receptor kinase BIR3 negatively regulates cell surface receptor complexes and thereby prevents unwanted activation of immune and hormone responses.
