Overlooked components of lipid metabolism: Odd‐chain polyunsaturated fatty acids in photosynthetic microorganisms

open access: yesJournal of Phycology, EarlyView.
Abstract This mini‐review examines odd‐carbon polyunsaturated fatty acids (odd‐PUFAs), a rare but biologically significant group of fatty acids in photosynthetic microorganisms. Odd‐PUFAs are straight‐chain fatty acids containing an odd number of carbon atoms and two or more methylene‐interrupted double bonds. They typically account for less than 1% of

Integrated Metabolomics and Selection Signal Analysis Provide Insights Into the Selection for Flavonol Biosynthesis Associated With Lettuce Quality Improvement

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Lettuce is a critical leafy vegetable consumed worldwide and is a substantial dietary source of health‐promoting compounds. Exploring changes in metabolism during lettuce domestication under artificial selection conditions is important to facilitate further breeding and cultivation for quality improvement.

Leaf Tissue‐Specific Phosphorus Allocation Is Linked to Leaf Lifespan in Chickpea Accessions

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Plants strategically allocate phosphorus (P) among leaf tissues to support physiological functions. However, there is limited understanding of contrasting leaf cellular P‐allocation patterns and their physiological consequences. We quantified leaf P fractions, photosynthetic P‐use efficiency (PPUE), and P‐remobilisation efficiency (PRE) in ...

Automated Phenotyping Unveils Trait‐Specific Genotypic Variation in Arbuscular Mycorrhiza Responsiveness in Maize (Zea mays)

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Arbuscular mycorrhiza (AM), a symbiosis between land plants and fungi that enhances plant mineral nutrition, has potential for application in sustainable agriculture. The extent to which plants benefit from the symbiosis depends on the plant‐fungal genotype combination, providing opportunities for breeding symbiosis‐optimized crops.

Chromium Isotopes: A Window into Atmospheric Oxygenation

open access: yes
Chromium (Cr) isotopes are pivotal proxies for understanding Earth’s atmospheric oxygenation history. This review highlights δ53Cr signatures as tools for reconstructing redox dynamics during events like the Great Oxidation Event (GOE) and the Neoproterozoic Oxygenation Event (NOE).

Integrating natural baselines into ecosystem restoration: scaling herbivore targets for European landscapes

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Herbivore‐mediated ecosystem processes are fundamental to biodiversity, yet have been greatly diminished by megafauna extinctions and replacement of wild herbivores by managed livestock. With increasing restoration ambitions—including the United Nations' (UN) Decade on Ecosystem Restoration and the European Union (EU) Nature ...

Early development of anoxia prior to the main euxinic phase of the Jenkyns Event on the margin of the Western Tethys (Sachrang Basin, Eastern Alps)

open access: yesSedimentology, EarlyView.
ABSTRACT Although the global expansion of oxygen‐depleted marine environments during the Early Toarcian Jenkyns Event (or Toarcian Oceanic Anoxic Event) is primarily inferred from successions in the NW European epicontinental basins, the timing of the expansion of anoxia in Tethyan basins, where hydrography potentially played a minor role, is poorly ...
