The phenolic compound salicylic acid (SA) is a key signalling molecule regulating local and systemic plant defense responses, mainly against biotrophs. Many microbial organisms, including pathogens, share the ability to degrade SA. However, the mechanism by which they perceive SA is unknown. Here we show that Ustilago maydis, the causal agent of corn smut disease, employs a so far uncharacteriz...

Salicylic acid (SA) plays a critical role in plant immunity responses against pathogen infection, especially in the establishment of systemic acquired resistance. Whether other forms of salicylates also function in plant immunity has not been explored. Our previous study has revealed that salicyloyl-aspartate (SA-Asp), the only reported endogenous SA-amino acid conjugate in plants, was highly a...

Salicylic acid (SA) has a central role in activating plant resistance to pathogens. SA levels increase in plant tissue following pathogen infection and exogenous SA enhances resistance to a broad range of pathogens. To study the relevance of the SA signaling in the flg22 response, we investigated the responses of SA-related mutants to flg22, a 22-amino acid peptide of the flagellin bacterial pr...

Current or voltage-type sense amplifier (SA) is the key element for sensing process of RFID transponder EEPROM. The performance of the EEPROM is influenced by the SA features like memory access time, power dissipation and the reliability. However, larger current or power dissipation put limitations on using current type SA with respect to voltage type SA. A low voltage SA with lower current con...

BACKGROUND Manual workers in the public sector have previously been found to be at risk of mental sickness absence (SA). As the impact of mental illness differs across economic sectors, this study investigated mental SA in the industrial sector, differentiating between office and production workers. METHODS Ten-year observational cohort study including 14 369 (8164 production and 6205 office)...

PURPOSE Mental health problems are associated with sickness absence (SA). The present study aimed at establishing which symptoms-distress, depression, anxiety, or somatization-at which symptom levels were associated with SA frequency and duration. Moreover, a number of possible confounders or effect modifiers were taken into account. METHODS A survey was completed by 3,678 employees of a larg...

In order to improve our understanding of situation awareness (SA) in teams performing in technologically advanced command, control, and communications (C3) operations, researchers need to develop valid approaches to assess both individual and shared SA. We investigated SA in an interdisciplinary military rescue operation training exercise. For this study, we developed procedures to measure the ...

Linköping University Differences in situational awareness and how to manage them in development of complex systems Abstract What's up, Doc? Situational awareness (SA) is about being aware of what is going on. Already when a complex system is developed there is an opportunity to help a future user of the system to form a better SA. Let us make the best out of this opportunity! When assessing SA,...

ABSTRACT The role of bacterially produced salicylic acid (SA) in the induction of systemic resistance in plants by rhizobacteria is far from clear. The strong SA producer Pseudomonas fluorescens WCS374r induces resistance in radish but not in Arabidopsis thaliana, whereas application of SA leads to induction of resistance in both plant species. In this study, we compared P. fluorescens WCS374r ...
