MDP25‐VDAC3 Complex Orchestrates Actin Remodeling and Mitochondrial Dynamics to Modulate Innate Immunity in Arabidopsis

Advanced Science, EarlyView.
This study reveals that actin remodeling regulates mitochondrial elongation as a defense strategy in plants. Flagellin perception induces fusion‐dependent elongation, supported by cortical actin bundles, to repair damage and boost ATP and ROS production.

Feedback control and its impact on generalist predator–prey system with prey harvesting

Nonlinear Analysis, 2019
This article examines the effectiveness of feedback control as a management policy on a generalist predator–prey system with prey harvesting. We discuss the result of implementing feedback control with respect to prey and predator separately.

Phase transitions in dependence of apex predator decaying ratio in a cyclic dominant system

, 2018
Cyclic dominant systems, like rock-paper-scissors game, are frequently used to explain biodiversity in nature, where mobility, reproduction and intransitive competition are on stage to provide the coexistence of competitors. A significantly new situation

Mechanism‐Driven Screening of Membrane‐Targeting and Pore‐Forming Antimicrobial Peptides

Advanced Science, EarlyView.
To combat antibiotic resistance, this study employs mechanism‐driven screening with machine learning to identify pore‐forming antimicrobial peptides from amphibian and human metaproteomes. Seven peptides are validated, showing minimal toxicity and membrane disruption.

A Non‐Mitophagy Activity of BNIP3L/NIX in Amygdala Glutamatergic Neurons is Essential for Contextual Fear Memory Formation

Advanced Science, EarlyView.
Contextual fear conditioning induces BNIP3L‐dependent mitochondrial fission in glutamatergic neurons of the BLA, independently of mitophagy. Loss of BNIP3L elevates Drp1Ser637 phosphorylation, thereby suppressing mitochondrial fission, compromising ATP production, and attenuating excitatory synaptic transmission.

On a Periodic Predator-Prey System with Holling III Functional Response and Stage Structure for Prey

Abstract and Applied Analysis, 2010
We propose and study the permanence of the following periodic Holling III predator-prey system with stage structure for prey and both two predators which consume immature prey. Sufficient and necessary conditions which guarantee the predator and the prey

Model of Eutrophication in Predator-Prey Systems [PDF]

, 1977
In this paper a model of a simple food-prey-predator system existing in a flow is built. The model predicts the emergence of sharp predator-prey oscillations when the initial food concentration is very high or the flow rate is very slow.

Delays in predator — prey systems (Introductory)

Bolletino di zoologia, 1979
Abstract Density of natural and experimental populations fluctuates. Oscillations may depend either from density-independent mechanisms, or from density-dependent mechanisms. In this paper the role of the delays in determining these oscillations is emphasized.

Mechanisms of Aristolochic Acid Resistance in Specialist Butterflies and Evolutionary Insights for Potential Protective Pathways

Advanced Science, EarlyView.
The study provides an extreme example of insect adaptation to highly toxic defenses of host plants, and investigates the complex strategies to resist carcinogenic aristolochic acids, including physical isolation, metabolic detoxification, and DNA repair.
