Generalized Mechanism Model for Ecosystem Hysteresis

open access: yesAdvanced Science, EarlyView.
A simplified model examines ecosystem transitions into alternative states after disturbances by leveraging positive and negative feedbacks. It identifies critical tipping points and quantifies hysteresis. Tests conducted on lakes, grasslands, and pitcher‐plant leaves align closely with empirical data and enable the prediction of recovery trajectories ...

Pathogenesis related protein 10 (PR-10): A component of multiple defense systems against biotic and abiotic stresses

open access: yesPlant Stress
During biotic stresses, plants deploy cognate elicitors to set off signal transduction networks that subsequently initiate differential expression of genes, designated as defense-related genes.

Interaction between arbuscular mycorrhizal fungi and Bacillus spp. in soil enhancing growth of crop plants

open access: yesFungal Biology and Biotechnology, 2019
Soil microorganisms play an important role in enhancing soil fertility and plant health. Arbuscular mycorrhizal fungi and plant growth promoting rhizobacteria form a key component of the soil microbial population.

Global Switches and Fine-Tuning—ABA Modulates Plant Pathogen Defense

open access: yesMolecular Plant-Microbe Interactions, 2008
Plants are obliged to defend themselves against a wide range of biotic and abiotic stresses. Complex regulatory signaling networks mount an appropriate defense response depending on the type of stress that is perceived.

Ecosystem‐Centered Robot Design: Toward Ecoresorbable Sustainability Robots (ESRs)

open access: yesAdvanced Science, EarlyView.
Robots exploring natural ecosystems can support monitoring and conservation, but must adopt ecosystem‐centered design to avoid pollution, waste, and damage. This review proposes guidelines for co‐designing ecoresorbable sustainability robots (ESRs), uniting materials, robotics, and ecological contexts in a single framework.

Molecules with a peptide link in protostellar shocks: a comprehensive study of L1157 [PDF]

open access: yes, 2014
Interstellar molecules with a peptide link -NH-C(=O)-, like formamide (NH$_2$CHO), acetamide (NH$_2$COCH$_3$) and isocyanic acid (HNCO) are particularly interesting for their potential role in pre-biotic chemistry.
