Chemical Modifications Mark Alternatively Spliced and Uncapped Messenger RNAs in ArabidopsisGlobal identification of RNA modifications that affect the Watson-Crick base-pairing edge across the Arabidopsis transcriptome provides insights into the many functions of these important additions.
Transcriptional Dynamics Driving MAMP-Triggered Immunity and Pathogen Effector-Mediated Immunosuppression in Arabidopsis Leaves Following Infection with Pseudomonas syringae pv tomato DC3000High-resolution microarray analysis of Pseudomonas syringae-inoculated Arabidopsis leaves reveals transcriptional dynamics underpinning basal defense and effector modulation leading to disease development.
RESEARCH ARTICLES
Functional Conservation in the SIAMESE-RELATED Family of Cyclin-Dependent Kinase Inhibitors in Land PlantsAlthough they play roles in many different developmental processes, the biochemical function of SMR-type CDK inhibitors is conserved among land plants.
The Maize PI/GLO Ortholog Zmm16/sterile tassel silky ear1 Interacts with the Zygomorphy and Sex Determination Pathways in Flower DevelopmentThe maize PI/GLO ortholog Zmm16/sts1 is a B class gene that interacts with the zygomorphy and sex determination pathways of maize.
Arabidopsis LEAFY COTYLEDON1 Mediates Postembryonic Development via Interacting with PHYTOCHROME-INTERACTING FACTOR4LEC1 interacts with PIF4 to mediate postembryonic development through coregulating expression of hypocotyl elongation-related genes via direct binding to the G-box element in the dark.
The WRKY Transcription Factor WRKY71/EXB1 Controls Shoot Branching by Transcriptionally Regulating RAX Genes in ArabidopsisEXB1 plays pivotal roles in shoot branching by positively regulating the key branch genes RAX1, RAX2, and RAX3 and by affecting auxin pathways.
Strigolactone Signaling in Arabidopsis Regulates Shoot Development by Targeting D53-Like SMXL Repressor Proteins for Ubiquitination and DegradationD53-like SMXLs regulate shoot branching and leaf development through the strigolactone signaling pathway by forming a complex with TPR2 and repressing transcription in Arabidopsis.
SMAX1-LIKE/D53 Family Members Enable Distinct MAX2-Dependent Responses to Strigolactones and Karrikins in ArabidopsisStrigolactones regulate shoot branching through MAX2-mediated degradation of a clade of SMAX1-LIKE proteins.
FILAMENTOUS FLOWER Is a Direct Target of JAZ3 and Modulates Responses to JasmonateYAB transcription factors interact with JAZ3 and are required for JA-mediated responses, such as anthocyanin accumulation, chlorophyll loss, and susceptibility to Pseudomonas syringae DC3000 infection.
Plants Release Precursors of Histone Deacetylase Inhibitors to Suppress Growth of CompetitorsChemical compounds in plant root exudates influence the growth of neighboring plants by interfering with their chromatin configuration and gene expression.
The EF-Hand Ca2+ Binding Protein MICU Choreographs Mitochondrial Ca2+ Dynamics in ArabidopsisThe mitochondrial Ca2+ uptake protein At-MICU shapes mitochondrial Ca2+ dynamics, providing molecular in vivo evidence for the existence and function of a mitochondrial uniporter complex in plants.
Light-Harvesting Complex Stress-Related Proteins Catalyze Excess Energy Dissipation in Both Photosystems of Physcomitrella patensHigh-light-dependent quenching of PSII is catalyzed by Photosystem II Subunit S (PSBS), whereas Light-Harvesting Complex Stress-Related (LHCSR) acts on both PSI and PSII in Physcomitrella patens.
Arabidopsis RZFP34/CHYR1, a Ubiquitin E3 Ligase, Regulates Stomatal Movement and Drought Tolerance via SnRK2.6-Mediated PhosphorylationRZFP34/CHYR1 functions as a ubiquitin E3 ligase and promotes stomatal movement in response to ABA and drought stress, during which RZFP34/CHYR1 activity is regulated by SnRK2.6-mediated phosphorylation.
A MYB/ZML Complex Regulates Wound-Induced Lignin Genes in MaizeA methyl jasmonate-dependent MYB-ZML regulatory mechanism links wounding stress to the derepression of lignin genes in maize.
Phosphorylation-Dependent Regulation of G-Protein Cycle during Nodule Formation in SoybeanComponents of heterotrimeric G-proteins directly interact with the soybean Nod factor receptors, which phosphorylate the regulatory RGS protein, thereby affecting G-protein cycle-dependent nodulation.
Septin-Dependent Assembly of the Exocyst Is Essential for Plant Infection by Magnaporthe oryzaeThe rice blast fungus targets polarized exocytosis to the exact point of plant infection using septin GTPases, which direct the exocyst complex to the appressorium pore.
