An improved method of preparing onion bulbs for the Alium test

Acta Societatis Botanicorum Poloniae, 2014
The tests on storage and preparation of onion (Allium cepa L.) bulbs presented in this paper were performed in order to obtain the highest possible number of roots of similar length, which would be suitable for performing the Allium test.

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.

Dancing with Hormones: A Current Perspective of Nitrate Signaling and Regulation in Arabidopsis

Frontiers in Plant Science, 2017
In nature and agriculture, nitrate availability is a main environmental cue for plant growth, development and stress responses. Nitrate signaling and regulation are hence at the center of communications between plant intrinsic programs and the ...

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

Characterization of Rice (Oryza sativa L.) Roots Versus Root Pulling Resistance as Selection Indices for Draught Tolerance [PDF]

, 1989
A technique described as Root Pulling Resistance (RPR) was used to evaluate genotypic differences in root growth and development of 50 rice germplasm accessions and cultivars. Several root characteristics in rice are associated with drought tolerance and

Integrated analysis of root microbiomes of soybean and wheat from agricultural fields [PDF]

, 2016
Root associated bacteria are critical for plant growth and health. Understanding the composition and role of root microbiota is crucial toward agricultural practices that are less dependent on chemical fertilization, which has known negative effects on ...

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.

Aplicações da curva de resistência no controle da qualidade física de um solo sob pastagem Applications of the resistance curve in the control of the physical quality of soils under grass

Pesquisa Agropecuária Brasileira, 2000
A degradação da qualidade física do solo pode estar associada com a compactação causada pelo pisoteio dos animais. A resistência do solo à penetração (RP) é um parâmetro físico utilizado para estabelecer o grau de compactação do solo. Contudo, esta varia

The Effects of Cytokinin on the Transcriptional Regulation of PIN Expression in Arabidopsis thaliana [PDF]

, 2012
The processes of cell division and differentiation are critical to the development of any multicellular organism. During the formation of plant roots these processes take place at a region of the root tip called the meristem.

Arabidopsis ROOT UVB SENSITIVE2/WEAK AUXIN RESPONSE1 is required for polar auxin transport [PDF]

, 2010
Auxin is an essential phytohormone that regulates many aspects of plant development. To identify new genes that function in auxin signaling, we performed a genetic screen for Arabidopsis thaliana mutants with an alteration in the expression of the auxin ...
