Identification of plant transcriptional activation domains.

Journal Article Nature · August 2024 Gene expression in Arabidopsis is regulated by more than 1,900 transcription factors (TFs), which have been identified genome-wide by the presence of well-conserved DNA-binding domains. Activator TFs contain activation domains (ADs) that recruit coactivato ... Full text Cite

Detailing Early Shoot Growth Arrest in Kro-0 x BG-5 Hybrids of Arabidopsis thaliana.

Journal Article Plant & cell physiology · April 2024 Shoot growth directly impacts plant productivity. Plants adjust their shoot growth in response to varying environments to maximize resource capture and stress resilience. While several factors controlling shoot growth are known, the complexity of the regul ... Full text Cite

Auxin and abiotic stress responses.

Journal Article Journal of experimental botany · December 2023 Plants are exposed to a variety of abiotic stresses; these stresses have profound effects on plant growth, survival, and productivity. Tolerance and adaptation to stress require sophisticated stress sensing, signaling, and various regulatory mechanisms. Th ... Full text Cite

Antigravitropic PIN polarization maintains non-vertical growth in lateral roots.

Journal Article Nature plants · September 2023 Lateral roots are typically maintained at non-vertical angles with respect to gravity. These gravitropic setpoint angles are intriguing because their maintenance requires that roots are able to effect growth response both with and against the gravity vecto ... Full text Cite

Angle-dependence and auxin asymmetry: towards the formulation of a universal theory of root gravitropism

Preprint · November 21, 2022 Full text Cite

Temperature-mediated flower size plasticity in Arabidopsis.

Journal Article iScience · November 2022 Organisms can rapidly mitigate the effects of environmental changes by changing their phenotypes, known as phenotypic plasticity. Yet, little is known about the temperature-mediated plasticity of traits that are directly linked to plant fitness such as flo ... Full text Cite

Connected phytohormone biosynthesis pathways at the core of growth-stress tradeoffs.

Journal Article Molecular plant · July 2022 Full text Cite

A. thaliana Hybrids Develop Growth Abnormalities through Integration of Stress, Hormone and Growth Signaling.

Journal Article Plant & cell physiology · July 2022 Hybrids between Arabidopsis thaliana accessions are important in revealing the consequences of epistatic interactions in plants. F1 hybrids between the A. thaliana accessions displaying either defense or developmental phenotypes have been revealing the rol ... Full text Cite

Leaf chlorosis in Arabidopsis thaliana hybrids is associated with transgenerational decline and imbalanced ribosome number.

Journal Article The New phytologist · November 2020 The interaction of two parental genomes can result in negative outcomes in offspring, also known as hybrid incompatibility. We have previously reported a case in which two recessively interacting alleles result in hybrid chlorosis in Arabidopsis thaliana. ... Full text Cite
