Sensitive plant (Mimosa pudica) hiding time depends on individual and state. [PDF]

, 2017
The decisions animals make to adjust their antipredator behavior to rapidly changing conditions have been well studied. Inducible defenses in plants are an antipredator behavior that acts on a longer time scale, but sensitive plants, Mimosa pudica, have ...

The heritability of inducible defenses in tadpoles [PDF]

Journal of Evolutionary Biology, 2005
AbstractThe evolution of plastic traits requires phenotypic trade‐offs and heritable traits, yet the latter requirement has received little attention, especially for predator‐induced traits. Using a half‐sib design, I examined the narrow‐sense heritability of predator‐induced behaviour, morphology, and life history in larval wood frogs (Rana sylvatica).

Silverleaf Whitefly Induces Salicylic Acid Defenses and Suppresses Effectual Jasmonic Acid Defenses [PDF]

Plant Physiology, 2006
Abstract The basal defenses important in curtailing the development of the phloem-feeding silverleaf whitefly (Bemisia tabaci type B; SLWF) on Arabidopsis (Arabidopsis thaliana) were investigated. Sentinel defense gene RNAs were monitored in SLWF-infested and control plants.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Synergistic Activation of Defense Responses in Arabidopsis by Simultaneous Loss of the GSL5 Callose Synthase and the EDR1 Protein Kinase

Molecular Plant-Microbe Interactions, 2010
Loss-of-function mutations in the EDR1 gene of Arabidopsis confer enhanced resistance to Golovinomyces cichoracearum (powdery mildew). Disease resistance mediated by the edr1 mutation is dependent on an intact salicylic acid (SA) signaling pathway, but ...

Transcriptome analysis of early stages of sorghum grain mold disease reveals defense regulators and metabolic pathways associated with resistance

BMC Genomics, 2021
Background Sorghum grain mold is the most important disease of the crop. The disease results from simultaneous infection of the grain by multiple fungal species. Host responses to these fungi and the underlying molecular and cellular processes are poorly

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Pathogen Phytosensing: Plants to Report Plant Pathogens

Sensors, 2008
Real-time systems that provide evidence of pathogen contamination in crops can be an important new line of early defense in agricultural centers. Plants possess defense mechanisms to protect against pathogen attack.

Cathemerality and Insensitivity to Predatory Fish Cues in Pond Isopods (Caecidotea communis)

Hydrobiology
Because animals threatened by visually oriented predators may respond in sun-lit daytime but not at night, invertebrate responses to predatory challenges may yield varying results based on the time period within the 24 h daily cycle. We predicted that in

A Plant Defense Response Effector Induces Microbial Apoptosis [PDF]

Molecular Cell, 2001
Osmotin is a tobacco PR-5 protein that has antifungal activity and is implicated in host-plant defense. We show here that osmotin induces apoptosis in Saccharomyces cerevisiae. Induction of apoptosis was correlated with intracellular accumulation of reactive oxygen species and was mediated by RAS2, but not RAS1.
