Paving the Way to Elucidate Hg's Role in Tumorigenesis

open access: yesAdvanced Science, EarlyView.
Tumorigenesis can result from diverse environmental carcinogens. Among them, mercury—a lifelong bioaccumulative Group 2B carcinogen—has tumorigenic potential that remains poorly understood due to confounding co‐exposures and limited organ‐specific data.

Multiple-locus heterozygosity, physiology and growth at two different stages in the life cycle of the Chilean oyster Ostrea chilensis [PDF]

open access: yes, 1996
A random sample of 150 individuals of a laboratory-produced cohort of Ostrea chilensis Philippi, 1845 was taken at 10 and 36 mo of age to estimate physiological variables and individual heterozygosity using 4 loci (Lap, Pgi, Pgm and Ca).

An Increasing Misalignment Between Crop Distribution and Environmental Resources Under Climate Change in China

open access: yesAdvanced Science, EarlyView.
Climate change reshapes the spatial alignment between crop production and environmental resources. Using multi‐source data and a crop model, integrated climatic, water, and soil endowments for maize and wheat are quantified and compared with harvest distributions.

Effects of Paclobutrazol on Podding and Photosynthetic Characteristics in Peanut

open access: yesPlant Production Science, 2003
The effects of paclobutrazol (PB) on podding habits and photosynthetic characteristics (COz assimilation rate, quantum yield of photosystem II (ΦSII) and chlorophyll content) were examined in peanut.

Genotypic variation of cut chrysanthemum response to high CO2 concentration: Growth, time to flowering and visual quality [PDF]

open access: yes, 2011
In this study sixteen cut chrysanthemum cultivars were used to evaluate the effects of high CO2 concentration (1500 µmol mol-1) on growth, time to flowering and visual quality as compared to the concentration used in commercial greenhouses (600 µmol mol ...

Coordination of Cyanobacterial Nitrate Assimilation and Photosynthesis by a Novel PsbO‐Interacting Protein PirN

open access: yesAdvanced Science, EarlyView.
PirN was identified as a previously uncharacterized PsbO‐interacting protein specifically induced in nitrate‐grown cyanobacteria. Loss of PirN leads to coordinated downregulation of PsbO and the nitrate reductase NarB, causing decreased PSII activity and impaired growth under nitrate conditions. Complementation with either PsbO or NarB largely restores

Does Spraying of Atrazine on Triazine-Resistant Canola Hybrid Impair Photosynthetic Processes? [PDF]

open access: yesPlanta Daninha, 2019
: Canola is an important rotation crop for the winter season and the use of atrazine-resistant hybrids can lead to an increase in yield. This work was aimed at evaluating the effect of atrazine on photochemical and biochemical processes of photosynthesis
