Morphodynamics of chloroplast network control light-avoidance response in the non-motile dinoflagellate Pyrocystis lunula [PDF]

open access: yesarXiv
Photosynthetic algae play a significant role in oceanic carbon capture. Their performance, however, is constantly challenged by fluctuations in environmental light conditions. Here, we show that the non-motile single-celled marine dinoflagellate Pyrocystis lunula can internally contract its chloroplast network in response to light. By exposing the cell

Molecular Phylogeny of Chinese Thuidiaceae with emphasis on Thuidium and Pelekium [PDF]

open access: yesarXiv, 2019
We present molecular phylogenetic investigation of Thuidiaceae, especially on Thudium and Pelekium. Three chloroplast sequences (trnL-F, rps4, and atpB-rbcL) and one nuclear sequence (ITS) were analyzed. Data partitions were analyzed separately and in combination by employing MP (maximum parsimony) and Bayesian methods.

Fast responses, rich insights: Optimizing experimental stream studies using periphyton for comprehensive environmental assessment

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Experimental streams (ESs) are enclosures of fluvial ecosystems designed as flume microcosms to simulate flowing waters and assess environmental disturbances on aquatic communities' structure and function under controlled conditions. This study presents an ES system that combines ecological relevance with reliability in a compact design ...

Neglecting acclimation of photosynthesis under drought can cause significant errors in predicting leaf photosynthesis in wheat

open access: yesGlobal Change Biology, Volume 29, Issue 2, Page 505-521, January 2023., 2023
Our study investigated how photosynthesis and its components acclimate to drought stress (DS) and growth temperature (Tgrowth) in wheat, and examined to what extent ignoring these acclimations would lead to errors in predicting photosynthesis. We found that both diffusional and biochemical parameters of photosynthesis and their thermal sensitivity ...

Characterisation of components and mechanisms involved in redox-regulation of protein import into chloroplasts [PDF]

open access: yes, 2009
The vast majority of chloroplast proteins is encoded in the nucleus and thus has to be posttranslationally imported into the organelle, a process that is facilitated by two multimeric protein machineries, the Toc and Tic complexes (translocon at the ...

Microbially Influenced Corrosion in Epoxy‐Ceramic Coated Carbon‐Steel Cooler

open access: yesMaterials and Corrosion, EarlyView.
A significant localization of corrosion attacks up to 1 mm deep were found in coated carbon‐steel cooler. Corrosion products and biofilm were enriched in mixed bacterial community including the genera Sulfuritalea and Methylotenera. Analysis of metabolic markers confirmed their coexistence with sulfate‐reducing bacteria.

Coordination of photosynthetic traits across soil and climate gradients

open access: yesGlobal Change Biology, Volume 29, Issue 3, Page 856-873, February 2023., 2023
Using an Australia‐wide photosynthetic trait dataset, we tested predictions from least‐cost optimality theory, which posits that plants balance nutrient use and water loss to optimize photosynthesis. We found that leaf nitrogen and rates of water loss co‐vary with one another in response to climate and to a lesser extent, soils.

Antifouling Coatings Inspired by Biological Templates

open access: yesMacromolecular Rapid Communications, EarlyView.
The polymeric coatings developed using biological templates combine antifouling properties of polymers with mechanical properties of micro‐ and nano‐particles yielding contact active, foulant releasable, and stimuli responsive materials with superior antifouling performance and demonstrate several applications in the marine environment, as delivery ...

Radiation‐constrained boundaries cause nonuniform responses of the carbon uptake phenology to climatic warming in the Northern Hemisphere

open access: yesGlobal Change Biology, Volume 29, Issue 3, Page 719-730, February 2023., 2023
The constraint of temperature and radiation on vegetation productivity was estimated with the variable θ. Values of θ differ during the start and end of season (SoS and EoS), indicating that radiation constraints the trend towards longer growing seasons but differently during spring and autumn.
