A genetic screen reveals Arabidopsis stomatal and/or apoplastic defenses against Pseudomonas syringae pv. tomato DC3000.
(PLoS pathogens, 2011-10-06)Bacterial infection of plants often begins with colonization of the plant surface, followed by entry into the plant through wounds and natural openings (such as stomata), multiplication in the intercellular space (apoplast) ... -
A plant genetic network for preventing dysbiosis in the phyllosphere.
(Nature, 2020-04-08)The aboveground parts of terrestrial plants, collectively called the phyllosphere, have a key role in the global balance of atmospheric carbon dioxide and oxygen. The phyllosphere represents one of the most abundant habitats ... -
Beyond QTL cloning.
(PLoS Genet, 2010-11-11) -
Detecting separate time scales in genetic expression data.
(BMC Genomics, 2010-06-16)BACKGROUND: Biological processes occur on a vast range of time scales, and many of them occur concurrently. As a result, system-wide measurements of gene expression have the potential to capture many of these processes ... -
Dual impact of elevated temperature on plant defence and bacterial virulence in Arabidopsis.
(Nature communications, 2017-11-27)Environmental conditions profoundly affect plant disease development; however, the underlying molecular bases are not well understood. Here we show that elevated temperature significantly increases the susceptibility of ... -
Dual transcriptomic analysis reveals metabolic changes associated with differential persistence of human pathogenic bacteria in leaves of Arabidopsis and lettuce.
(G3 (Bethesda, Md.), 2021-12)Understanding the molecular determinants underlying the interaction between the leaf and human pathogenic bacteria is key to provide the foundation to develop science-based strategies to prevent or decrease the pathogen ... -
Ectopic Expression of OsJAZs Alters Plant Defense and Development.
(International journal of molecular sciences, 2022-04)A key step in jasmonic acid (JA) signaling is the ligand-dependent assembly of a coreceptor complex comprising the F-box protein COI1 and JAZ transcriptional repressors. The assembly of this receptor complex results ... -
Genome-wide direct target analysis reveals a role for SHORT-ROOT in root vascular patterning through cytokinin homeostasis.
(Plant Physiol, 2011-11)SHORT-ROOT (SHR) is a key regulator of root growth and development in Arabidopsis (Arabidopsis thaliana). Made in the stele, the SHR protein moves into an adjacent cell layer, where it specifies endodermal cell fate; it ... -
Germination Responses to Vegetation in Maternal and Progeny Environments
(2016-04-25)The conditions in which a seed germinates is crucial to the survival and fitness of the plant. The ability to regulate germination given certain conditions is thus extremely important. This research examines the plastic ... -
Information processing without brains--the power of intercellular regulators in plants.
(Development, 2010-04)Plants exhibit different developmental strategies than animals; these are characterized by a tight linkage between environmental conditions and development. As plants have neither specialized sensory organs nor a nervous ... -
Intergenic and genic sequence lengths have opposite relationships with respect to gene expression.
(PLoS One, 2008)Eukaryotic genomes are mostly composed of noncoding DNA whose role is still poorly understood. Studies in several organisms have shown correlations between the length of the intergenic and genic sequences of a gene and the ... -
Jasmonate perception by inositol-phosphate-potentiated COI1-JAZ co-receptor.
(Nature, 2010-11)Jasmonates are a family of plant hormones that regulate plant growth, development and responses to stress. The F-box protein CORONATINE INSENSITIVE 1 (COI1) mediates jasmonate signalling by promoting hormone-dependent ... -
Linnemannia elongata (Mortierellaceae) stimulates Arabidopsis thaliana aerial growth and responses to auxin, ethylene, and reactive oxygen species.
(PloS one, 2022-01)Harnessing the plant microbiome has the potential to improve agricultural yields and protect plants against pathogens and/or abiotic stresses, while also relieving economic and environmental costs of crop production. While ... -
Localization of DIR1 at the tissue, cellular and subcellular levels during Systemic Acquired Resistance in Arabidopsis using DIR1:GUS and DIR1:EGFP reporters.
(BMC plant biology, 2011-01)BACKGROUND: Systemic Acquired Resistance (SAR) is an induced resistance response to pathogens, characterized by the translocation of a long-distance signal from induced leaves to distant tissues to prime them for increased ... -
Minimum Requirements for Changing and Maintaining Cell Fate in the Arabidopsis Root
(2018)A cell’s trajectory from stem cell to differentiation, while often portrayed as a linear progression, is best described as a network that produces a mature state through several pathways acting together. There are few examples ... -
NCP activates chloroplast transcription by controlling phytochrome-dependent dual nuclear and plastidial switches.
(Nature communications, 2019-06-14)Phytochromes initiate chloroplast biogenesis by activating genes encoding the photosynthetic apparatus, including photosynthesis-associated plastid-encoded genes (PhAPGs). PhAPGs are transcribed by a bacterial-type RNA polymerase ... -
O-GlcNAcylation of master growth repressor DELLA by SECRET AGENT modulates multiple signaling pathways in Arabidopsis.
(Genes & development, 2016-01)The DELLA family of transcription regulators functions as master growth repressors in plants by inhibiting phytohormone gibberellin (GA) signaling in response to developmental and environmental cues. DELLAs also play a central ... -
Oxicam-type non-steroidal anti-inflammatory drugs inhibit NPR1-mediated salicylic acid pathway.
(Nature communications, 2021-12)Nonsteroidal anti-inflammatory drugs (NSAIDs), including salicylic acid (SA), target mammalian cyclooxygenases. In plants, SA is a defense hormone that regulates NON-EXPRESSOR OF PATHOGENESIS RELATED GENES 1 (NPR1), the ... -
Redox rhythm reinforces the circadian clock to gate immune response.
(Nature, 2015-07-23)Recent studies have shown that in addition to the transcriptional circadian clock, many organisms, including Arabidopsis, have a circadian redox rhythm driven by the organism's metabolic activities. It has been hypothesized ... -
Regulation of Cell Death During Arabidopsis Effector Triggered Immunity
(2019)In the plant innate immune system, diverse signals from a wide range of pathogens converge on the same output, effector triggered immunity (ETI) and the associated programmed cell death (PCD). Past genetic studies have succeeded ...
