Meloidogyne incognita penetration and development were studied in roots of highly resistant (PI 96354, PI 417444), resistant (Forrest), and susceptible (Bossier) soybean genotypes. Although more second-stage juveniles (J2) had penetrated roots of PI 96354 and PI 417444 than roots of Forrest and Bossier by 2 days after inoculation, fewer J2 were present in roots of PI 96354 at 4 days after inocu...

CTLA-4 is a T cell antigen that is structurally related to CD28 and serves as a high affinity ligand for the B cell antigen B7-1/2. Unlike CD28, the function of CTLA-4 is unclear, although reports have implicated the antigen in the costimulation of T cells. Recently, phosphatidylinositol 3-kinase (PI 3-kinase) has been implicated in the costimulatory function of CD28 by virtue of its ability to...

The RabA4b GTPase labels a novel, trans-Golgi network compartment displaying a developmentally regulated polar distribution in growing Arabidopsis thaliana root hair cells. GTP bound RabA4b selectively recruits the plant phosphatidylinositol 4-OH kinase, PI-4Kbeta1, but not members of other PI-4K families. PI-4Kbeta1 colocalizes with RabA4b on tip-localized membranes in growing root hairs, and ...

The principal aim of this paper is to employ Bessel-type operators in proving the inequality $$\displaystyle \begin{aligned} \int _0^\pi dx \, |f'(x)|{ }^2 \geq \dfrac {1}{4}\int {|f(x)|{ }^2}{\sin ^2 (x)}+\dfrac |f(x)|{ }^2,\quad f\in H_0^1 ((0,\pi )), \end{aligned} $$ where both constants 1?4 appearing above are optimal. In addition, strict sense that equality holds if and only f ? 0. ...

The phosphoinositide phosphatidylinositol 4,5-bisphosphate [PI(4,5)P2] regulates the activity of many actin-binding proteins and as such is an important modulator of cytoskeleton organization during cell migration, for example. In migrating cells actin remodeling is tightly regulated and localized; therefore, how the PI(4,5)P2 level is spatially and temporally regulated is crucial to understand...

Using 6.32~fb$^{-1}$ of $e^+e^-$ collision data recorded by the BESIII detector at center-of-mass energies between $4.178$ to $4.226$~GeV, we present first measurement decay $D_s^+\to f_0(980)e^+\nu_e,\,f_0(980)\to \pi^0\pi^0$. The product branching fraction \pi^0\pi^0$ is measured be $(7.9\pm1.4_{\rm stat} \pm0.3_{\rm syst})\times 10^{-4}$, with a statistical significance $7.8\sigma$. Furtherm...

A continuous culture technique was used to study the phosphorus requirements of rumen micro-organisms. Solutions of artificial saliva containing 120, 80, 40 and 0 mg inorganic phosphorus (Pi)/l were infused into the reaction vessels previously inoculated with rumen contents, resulting in Pi concentrations in the vessel contents of 48, 28, 4 and less than 1 mg/l respectively. Various fermentativ...

Abstract Inorganic phosphate (Pi) deficiency is a main limiting factor on crops growth and to select low-Pi tolerant breeding lines very significant for crop breeding. Here, two contrasting maize ( Zea mays L.) showed different physiological response Pi deficiency. The QXN233 maintained normal growth, including high fresh weight, green leaves, strong shoots, numerous roots relative that of the ...

The first search for the doubly heavy $\it{\Omega}_{bc}^{\rm0}$ baryon and a $\it{\Xi}_{bc}^{\rm0}$ are performed using $pp$ collision data collected via LHCb experiment from 2016 to 2018 at centre-of-mass energy of $13TeV$, corresponding an integrated luminosity 5.2$fb^{-1}$. baryons reconstructed their decays $\it{\Lambda_{c}^{+}\pi^{-}}$ $\it{\Xi_{c}^{+}\pi^{-}}$. No significant excess is fo...

Emerging evidence now implicates phosphatidylinositol 4-kinases (PI4K), enzymes that generate PI(4)P from phosphatidylinositol (PtdIns), in cancer. In this study, we investigate the role of PI4KIIIb, one of four mammalian PI4Ks, in breast cancer. Although PI4KIIIb protein levels are low in normal breast tissue, we find that approximately 20% of primary human breast tumors overexpress it. Expres...
