An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots

open access: yesFEBS Letters, EarlyView.
This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...

An Asp376Glu substitution in ALS gene and enhanced metabolism confers high tribenuron-methyl resistance in Sinapis alba

open access: yesFrontiers in Plant Science, 2022
Acetolactate synthase (ALS) inhibiting herbicides (group 2) have been widely applied for the last 20 years to control Sinapis alba in cereal crops from southern Spain. In 2008, a tribenuron-methyl (TM) resistant (R) S.

Evolved polygenic herbicide resistance in Lolium rigidum by low-dose herbicide selection within standing genetic variation [PDF]

open access: yes, 2012
The interaction between environment and genetic traits under selection is the basis of evolution. In this study, we have investigated the genetic basis of herbicide resistance in a highly characterized initially herbicide-susceptible Lolium rigidum ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Additional Resistance to any Fluoroquinolones among Multidrug-resistant Mycobacterium tuberculosis Isolates from North Coastal Andhra Pradesh, India

open access: yesJournal of Pure and Applied Microbiology, 2021
Fluoroquinolones (FQ) are integral part of multidrug resistant/rifampicin resistant tuberculosis (MDR-TB/RR TB) treatment regimens. FQ resistance in MDR-TB lead to narrower treatment options and poor treatment outcomes.

Nitroheterocyclic drug resistance mechanisms in Trypanosoma brucei [PDF]

open access: yes, 2015
OBJECTIVES: The objective of this study was to identify the mechanisms of resistance to nifurtimox and fexinidazole in African trypanosomes. METHODS: Bloodstream-form Trypanosoma brucei were selected for resistance to nifurtimox and fexinidazole by ...

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...
