New biosensors and transgenic mice for multiplex cGMP imaging

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Cyclic guanosine monophosphate (cGMP) is a versatile second messenger that is important for human (patho‐)physiology and pharmacotherapy. Live‐cell imaging of cGMP with biosensors allows to elucidate its spatiotemporal dynamics in real time under close‐to‐native conditions. However, to monitor two separate cGMP pools or cGMP/cAMP

Determination of the genetic stability in cassava plants obtained by somatic embryogenesis and organogenesis using AFLP

open access: yesBiotecnología Vegetal, 2002
AFLP techniques have been reported to determine the genetic stability at a molecular level of cassava plants propagated by several methods: somatic embryogenesis, organogenesis and field conditions. ‘CMC-76’, ‘CEMSA 74-725’ and ‘Señorita’ clones from the

PDE4D and PDE3B orchestrate distinct cAMP microdomains in 3T3‐L1 adipocytes

open access: yesBritish Journal of Pharmacology, EarlyView.
Basal conditions: •Ins/PDE3B lowers cytoplasmic cAMP (cyt‐cAMP) without affecting plasma membrane cAMP (pm‐cAMP). •Insulin decreases lipid droplet cAMP (LD‐cAMP) independent of PDE3B. •FGF1/PDE4D modestly reduces both cyt‐ and pm‐cAMP, while PDE4D alone can modulate LD‐cAMP. ISO stimulation: •Ins/PDE3B has minimal impact on cyt‐cAMP.

A Small Family of Elements with Long Inverted Repeats is Located Near Sites of Developmentally Regulated DNA Rearrangement in \u3cem\u3eTetrahymena thermophila\u3c/em\u3e [PDF]

open access: yes, 1994
Extensive DNA rearrangement occurs during the development of the somatic macronucleus from the germ line micronucleus in ciliated protozoans. The micronuclear junctions and the macronuclear product of a developmentally regulated DNA rearrangement in ...

Biostimulants in plant brassinosteroid hormone receptor BRI1 activation—a new system to evaluate activation capacity

open access: yesThe FEBS Journal, EarlyView.
A novel assay evaluates plant biostimulants targeting the brassinosteroid receptor BRI1, a central component in plant growth and development. By expressing BRI1 in fission yeast, functional activation by brassinolide (BL) was enabled. Transcriptomic profiling identified BL‐responsive genes, leading to a GFP‐based reporter system. This platform offers a

Construcción de una genoteca de cDNA de fríjol (Phaseolus vulgaris L.) para mapeo genético

open access: yesActa Agronómica, 1995
<p>A small cDNA library from beans (Phaseolus vulgaris L.) of about 1500 clones was constructed, to further saturate the bean RFLP linkage map. The primarily synthesized cDNAs were amplified by PCR using the adaptors as primers for amplification ...

Heterologous plastoquinone production using a newly identified O2‐dependent cyanobacterial hydroxylase

open access: yesThe FEBS Journal, EarlyView.
In this study, we confirm that PlqH is the hydroxylase operating in plastoquinone biosynthesis in photosynthetic cyanobacteria (Cyanobacteriia). Our phylogenetic analyses demonstrate that cyanobacterial PlqH homologues originated from hydroxylases involved in ubiquinone biosynthesis in bacteria. Plastoquinone production in Escherichia coli was achieved

Molecular basis of antibiotic sensing by the TetR family regulator CecR – a structural perspective

open access: yesThe FEBS Journal, EarlyView.
Escherichia coli CecR, a member of the TetR family regulators, senses selected antibiotics and activates the expression of a putative drug efflux pump. Although present in many pathogenic Enterobacteriales strains, CecR remains poorly characterized. We present the first CecR crystal structure, which reveals a unique tunnel‐like ligand‐binding cavity ...
