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.

Accounting for sap flow from different parts of the root system improves the prediction of xylem ABA concentration in plants grown with heterogeneous soil moisture. [PDF]

, 2008
When soil moisture is heterogeneous, sap flow from, and ABA status of, different parts of the root system impact on leaf xylem ABA concentration ([X-ABA]leaf). The robustness of a model for predicting [X-ABA]leaf was assessed.

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

INFLUENCE OF FERTILIZERS ON ACCUMULATION OF HEAVY METAL IN SOIL AND PHYTO MASS OF GRAIN CROPS

Зерновое хозяйство России, 2018
It’s common knowledge that heavy metal (HM) can enter the soil together with fertilizers which contaminates agricultural landscapes. The purpose of the research is to study influence of fertilizers on accumulation and migration of Cd, Pb ,Zn, Cu, Co, Mn ...

Qualidade de mudas clonais de Eucalyptus urophylla x E. grandis em função do substrato Quality of Eucalyptus urophylla x E. grandis cuttings as a function of substrate

Revista Brasileira de Engenharia Agrícola e Ambiental, 2012
Considerando a crescente demanda por mudas florestais e a escassez de matérias-primas dos substratos utilizados para o crescimento das plantas, faz-se necessário avaliar novos componentes e formulações que assegurem a qualidade das mudas.

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.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
