Soybean Inositol Polyphosphate 5‐Phosphatase 8 Confers Salt Tolerance by Reducing Sodium Influx Through Inositol 1,4,5‐Trisphosphate Signalling

Plant, Cell &Environment, EarlyView.
ABSTRACT Evidence suggests that the metabolism of inositol and its derivatives may be involved in various biological processes including salt tolerance, but there has been limited understanding. Ectopic expression of Gs5PTase8, an inositol polyphosphate 5‐phosphatase cloned from wild soybean (Glycine soja), significantly enhanced salt tolerance in ...

Discovery of three binary millisecond pulsars

The Astrophysical Journal, 1994
We report the discovery of three binary millisecond pulsars in circular orbits with low-mass companions from a continuing survey of the southern sky with the Parkes radio telescope. The three pulsars, PSR J0034-0534, PSR J1045-4509, and PSR J2145-0750 have pulse periods of 1.87, 7.47, and 16.05 ms and orbital periods of 1.6, 4.1, and 6.8 days ...

CHIME Discovery of a Binary Pulsar with a Massive Nondegenerate Companion

The Astrophysical Journal, 2023
Of the more than 3000 radio pulsars currently known, only ∼300 are in binary systems, and only five of these consist of young pulsars with massive nondegenerate companions.

New Binary and Millisecond Pulsars from Arecibo Drift-Scan Searches [PDF]

, 2004
We discuss four recycled pulsars found in Arecibo drift-scan searches. PSR J1944+0907 has a spin period of 5.2 ms and is isolated. The 5.8-ms pulsar J1453+19 may have a low-mass companion.

CONSTRAINTS ON BLACK HOLE/HOST GALAXY CO-EVOLUTION AND BINARY STALLING USING PULSAR TIMING ARRAYS [PDF]

, 2016
Pulsar timing arrays are now setting increasingly tight limits on the gravitational wave background from binary supermassive black holes (SMBHs). But as upper limits grow more constraining, what can be implied about galaxy evolution? We investigate which

Discovery of Five Binary Radio Pulsars

The Astrophysical Journal, 2001
We report on five binary pulsars discovered in the Parkes multibeam Galactic plane survey. All of the pulsars are old, with characteristic ages 1-11 Gyr, and have relatively small inferred magnetic fields, 5-90e8 G. The orbital periods range from 1.3 to 15 days.

Extended Emission from the PSR B1259-63/SS 2883 Binary Detected with Chandra

, 2011
PSR B1259-63 is a middle-aged radio pulsar (P=48 ms, tau=330 kyr, Edot=8.3*10^{35} erg/s) in an eccentric binary (P_orb =3.4 yr, e=0.87) with a high-mass Be companion, SS 2883.

New Direct Observational Evidence for Kicks in SNe [PDF]

, 2000
We present an updated list of direct strong evidence in favour of kicks being imparted to newborn neutron stars. In particular we discuss the new cases of evidence resulting from recent observations of the X-ray binary Circinus X-1 and the newly ...

MICROARCSECOND VLBI PULSAR ASTROMETRY WITH PSRπ. I. TWO BINARY MILLISECOND PULSARS WITH WHITE DWARF COMPANIONS [PDF]

, 2016
Model-independent distance constraints to binary millisecond pulsars (MSPs) are of great value to both the timing observations of the radio pulsars and multiwavelength observations of their companion stars.
