Computational characterisation of ecological hazard and risk of environmental mixtures. [PDF]

EFSA J
The project Computational characterisation of ecological hazard and risk of environmental mixtures focused on two key priorities in advancing a next‐generation risk assessment (NGRA) workflow: (i) transitioning to assessing mixtures and (ii) utilising ...

The life story of Albert W. Frenkel (1919-2015): a pioneer in photosynthesis research. [PDF]

Photosynthetica, 2023
In this historical perspective, we focus on selected discoveries that Albert Frenkel (1919-2015) made all by himself - single-handedly - which is the discovery of photophosphorylation and NAD reduction in anoxygenic photosynthetic bacteria.

ATP Is a Major Determinant of Phototrophic Bacterial Longevity in Growth Arrest. [PDF]

mBio, 2023
How bacteria transition into growth arrest as part of stationary phase has been well-studied, but our knowledge of features that help cells to stay alive in the following days and weeks is incomplete.

ATP Synthase Members of Chloroplasts and Mitochondria in Rubber Trees (Hevea brasiliensis) Response to Plant Hormones. [PDF]

Plants (Basel)
ATP synthase is a key enzyme in photophosphorylation in photosynthesis and oxidative phosphorylation in respiration, which can catalyze the synthesis of ATP and supply energy to organisms. ATP synthase has been well studied in many animal species but has

Genomic insights into the alphaproteobacterium <i>Georhizobium</i> sp. MAB10 revealed a pathway of Mn(II) oxidation-coupled anoxygenic photoautotrophy: a novel understanding of the biotic process in deep-sea ferromanganese nodule formation. [PDF]

mBio
Under light conditions, Mn(II) facilitates the photoautotrophic growth of Georhizobium sp. MAB10, a strain derived from deep-sea ferromanganese nodules, along with the generation of dark Mn oxides (β-MnO2). This study investigated the genetic basis of Mn(

PHR1 mediates rapid high light responses and acclimation to high photosynthetic activity. [PDF]

Plant J
SUMMARY Changing light intensity requires immediate metabolic adjustment which involves reprogramming of both plastidial and nuclear gene expression, but the signaling pathways behind such responses are not fully understood. Here we report that an increase in light intensity causes fluctuations of Pi levels in the chloroplasts of Arabidopsis thaliana ...

Bacteriophages in the Rhizosphere: Roles in Nutrient Cycling, Bacterial Community Structure, and Animal-Mediated Dispersal. [PDF]

Microbiologyopen
This review discusses bacteriophages' roles in soil ecosystems, highlighting their impact on nutrient cycling, plant health, and soil remediation, as well as animal‐mediated phage dispersal mechanisms. Overall, while bacteriophages have potential biotechnological applications, their negative effects on microbial functions and nutrient cycling highlight

OsCKq1 Regulates Heading Date and Grain Weight in Rice in Response to Day Length. [PDF]

Rice (N Y)
Background Photoperiod sensitivity is among the most important agronomic traits of rice, as it determines local and seasonal adaptability and plays pivotal roles in determining yield and other key agronomic characteristics. By controlling the photoperiod,
