The Advantaged Salt Inducible Suaeda salsa SsNRT2.5 and Its Promoter Significantly Enhance Nitrate Transport Efficiency and Salt Tolerance in Transgenic Arabidopsis and Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Efficient nitrogen (N) uptake is critical for crop yield, but soil salinization inhibits plant nitrogen acquisition. In this study, the nitrate (NO3−) transporter gene SsNRT2.5 and its promoter from the halophyte Suaeda salsa was investigated to elucidate the functional role in NO3− transport under salinity and low NO3−–N conditions.

Concurrent Measurement of O2 Production and Isoprene Emission During Photosynthesis: Pros, Cons and Metabolic Implications of Responses to Light, CO2 and Temperature

Plant, Cell &Environment, EarlyView.
ABSTRACT Traditional leaf gas exchange experiments have focused on net CO2 exchange (Anet). Here, using California poplar (Populus trichocarpa), we coupled measurements of net oxygen production (NOP), isoprene emissions and δ18O in O2 to traditional CO2/H2O gas exchange with chlorophyll fluorescence, and measured light, CO2 and temperature response ...

Comparison of VOC measurements made by PTR-MS, adsorbent tubes–GC-FID-MS and DNPH derivatization–HPLC during the Sydney Particle Study, 2012: a contribution to the assessment of uncertainty in routine atmospheric VOC measurements

, 2017
. Understanding uncertainty is essential for utilizing atmospheric volatile organic compound (VOC) measurements in robust ways to develop atmospheric science. This study describes an inter-comparison of the VOC data, and the derived uncertainty estimates,

Tudor England and Stewart Scotland Through Spanish Eyes: A Complete Transcription and Translation of Pedro de Ayala's Letter of 1498 to King Ferdinand of Castile and Queen Isabella of Aragon

Renaissance Studies, EarlyView.
Abstract Pedro de Ayala served as a diplomat for King Ferdinand II of Aragon and Queen Isabella I of Castile at the courts of Henry VII, King of England, and James IV, King of Scots. In July 1498, he wrote a letter, partly in cipher, to report to his king and queen on such matters as Spain's interests in international diplomacy; the characters and ...

Inhaled 5‐HT1B/1D Receptor Antagonist Attenuates Sumatriptan‐Induced Sensitization of Capsaicin‐Sensitive Lung Vagal Afferents: Implications for Preventing Sumatriptan‐Associated Adverse Chest Symptoms

Comprehensive Physiology, Volume 16, Issue 2, April 2026.
Our previous study suggests that sumatriptan‐induced chest discomfort is associated with hypersensitivity of CSLV afferents via 5‐HT1B/1D receptors on nerve endings. The present study demonstrates that inhaled 5‐HT1B/1D receptor antagonism suppresses this hypersensitivity without compromising antimigraine efficacy, supporting local pulmonary antagonism

Savannah and Boreal Biomass Burning as a Source for Cloud Condensation Nuclei

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Aerosol particles emitted in wildfires can contribute to radiative forcing via aerosol‐cloud interactions and by directly interacting with solar radiation. Wildfire emissions increase the concentration of cloud condensation nuclei (CCN) in the atmosphere and thus affect cloud properties (e.g., cloud brightness).

A comparison of new measurements of total monoterpene flux with improved measurements of speciated monoterpene flux [PDF]

Atmospheric Chemistry and Physics, 2005
Many monoterpenes have been identified in forest emissions using gas chromatography (GC). Until now, it has been impossible to determine whether all monoterpenes are appropriately measured using GC techniques.
