Diversity among genotypes of conilon coffee selected in Espírito Santo state

Bioscience Journal, 2015
The use of multivariate techniques for factor analysis is an efficient alternative for coffee breeding programs. This study aimed to evaluate the genetic diversity of 60 genotypes of conilon coffee based on agronomic performance in the northern state of ...

The Identity of Clones

The Journal of Medicine and Philosophy, 1999
A common concern with respect to cloning is based on the belief that cloning produces identical individuals. This is a fundamental misunderstanding of what type of identity-relation cloning involves. The concept "identity" is ambiguous, and the statement that cloning produces "identical" individuals is not meaningful unless the notion of identity is ...

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Defining Human Regulatory T Cells beyond FOXP3: The Need to Combine Phenotype with Function

Cells
Regulatory T cells (Tregs) are essential to maintain immune homeostasis by promoting self-tolerance. Reduced Treg numbers or functionality can lead to a loss of tolerance, increasing the risk of developing autoimmune diseases.

Crescimento in vitro de plântulas de batata em diferentes doses de cádmio In vitro growth of potato plantlets in different doses of cadmium

Ciência Rural, 2009
Devido, principalmente, às ações antropogênicas, tais como industrialização e uso de insumos na agricultura, os níveis de cádmio têm aumentado em muitos solos agrícolas.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Comportamiento de seis clones de "cacao" (Theobroma cacao L.) en Guasaganda, provincia de Cotopaxi, Ecuador

La Granja: Revista de Ciencias de la Vida, 2008
En la actualidad, no existe una variedad nacional genéticamente pura del cacao, pues lo que se encuentra es una mezcla de híbridos naturales que se agrupan en una población conocida con el nombre de complejo “Nacional x Trinitario”.
