Sphaerochara canadensis (Charophyceae): A circumpolar species with a high temperature optimum. [PDF]

J Phycol
Abstract Sphaerochara canadensis, an aquatic macrophyte belonging to the Characeae, is described as a species with a circumpolar distribution and occurs in the polar (to boreal) zonobiomes, suggesting that it is cold‐stenothermic. A recent report of an occurrence in Lake Wolfgangsee, Austria, contradicted this assumption, prompting this study to ...

Automated Detection and Monitoring of Ground-Nesting Bee Nests Using Drone Imagery and Deep Learning. [PDF]

Ecol Evol
We demonstrate the feasibility of integrating drone‐based image acquisition with deep learning to accurately detect soil mounds produced by ground‐nesting bees, indicating nest presence, and reliably distinguish them from other soil surface deposits. This approach has the potential to gain new insights into bee nesting biology and population dynamics ...

Bausteine zu einer Oral History der Wissenschaftsgeschichte Auf der Suche: von der Biologie und der Philosophie zur Wissenschaftsgeschichte. Interview mit Soraya de Chadarevian. [PDF]

Ber Wiss
Wie kann man einen historischen Blick auf das eigene Fach werfen? Diese Frage ist nicht einfach zu beantworten – will man einerseits nicht in einer Nabelschau und Hagiographie enden, andererseits aber auch keinen umfassenden Entwurf einer zukünftigen Historiographie vorlegen.

PPR596 Is Required for nad2 mRNA Splicing and Complex I Biogenesis in Mitochondria of Arabidopsis thaliana. [PDF]

Physiol Plant
ABSTRACT Several genes in the mitochondria of angiosperms are interrupted by introns, and their posttranscriptional excision involves numerous nucleus‐encoded auxiliary factors. Most of these factors are of eukaryotic origin, among them members of the pentatricopeptide‐repeat (PPR) family of RNA‐binding proteins.

Transcriptomic footprints disclose specificity of reactive oxygen species signaling in Arabidopsis [PDF]

, 2006
Reactive oxygen species ( ROS) are key players in the regulation of plant development, stress responses, and programmed cell death. Previous studies indicated that depending on the type of ROS ( hydrogen peroxide, superoxide, or singlet oxygen) or its ...

Differential expression of CCD4(4B) drives natural variation in fruit carotenoid content in strawberry (Fragaria spp.). [PDF]

Plant Biotechnol J
Summary Carotenoids are a diverse group of pigments imparting red, orange, and yellow hues to many horticultural plants, also enhancing their nutritional properties and health benefits. In strawberry, the genetic and molecular mechanisms regulating the natural variation of fruit carotenoid composition remain largely unexplored.

Interaction between bacterial phytochromes Agp1 and Agp2 of Agrobacterium fabrum by fluorescence resonance energy transfer and docking studies. [PDF]

FEBS Lett
The interaction between Agrobacterium fabrum phytochromes Agp1 and Agp2 was studied using FRET. Full‐length and truncated proteins with varied label positions provided spatial insights, narrowing down from many docking models to three. These models explain Agp2's reduction in Agp1 autophosphorylation, with Arg83 of Agp2 specifically evolved to interact

Excerpt: Not all historians agree thoroughly with Julius von Sachs\u27 suggestion in the Geschichte der Botanik (1875) that the work of Carl von Linnd marked the conclusion of an old epoch rather than the beginning of a new one, but it is true that most ...
