Comparing the Effects of Microplastics From Conventional Cigarette Butts and Heated Tobacco Device: The Role of UV‐Induced Aging

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Despite the widespread presence of cigarette butts in the environment, the potential toxicological effects posed by microplastics (MPs) derived from them remain poorly understood. In this study, we compared the effects of MPs from conventional cigarette butts (cellulose acetate) and heated tobacco devices (cellulose acetate and polylactic acid

Ecological scale mediates nonlinear relationships of animal nutrient excretion with dissolved organic matter

open access: yesJournal of Animal Ecology, EarlyView.
We show that nutrient excretion by vertebrates and invertebrates varies nonlinearly with dissolved organic matter concentration and composition and by taxonomic rank, with stronger patterns at the individual compared to the community level. Our findings highlight the importance of examining animal‐mediated nutrient cycling across taxa and ecological ...

Phenotypic characterization of Arabidopsis thaliana mutants that alleviate root growth defects in a vitamin B6 biosynthesis mutant

open access: yesThe FEBS Journal, EarlyView.
Vitamin B6 is a critical molecule for plant metabolism and development. Rsr4‐1, a loss‐of‐function mutant in a vitamin B6 biosynthesis gene, has a distinct short root phenotype. Here we describe five novel suppressor mutants with an rsr4‐1 background that have normalized root growth and distinct phenotypic and molecular characteristics, representing a ...

C‐type cyclin CycC1;1 delays leaf senescence by interacting with and inhibiting MYC2 in Arabidopsis

open access: yesJournal of Integrative Plant Biology, EarlyView.
The C‐type cyclin CycC1;1 interacts with MYC2 and MED25 to block their association and RNA polymerase II recruitment, thereby repressing senescence‐associated gene expression and delaying leaf senescence in Arabidopsis. Unlike jasmonic acid‐inducible JAZ repressors, CycC1;1 operates independently of jasmonic acid signaling, representing an ...

Light signaling controls chloroplast pyruvate metabolism through the STF1/2–PKP1 module in soybean

open access: yesJournal of Integrative Plant Biology, EarlyView.
In soybean, light‐responsive proteins switch on GmPKP1, which boosts chloroplast pyruvate production. This increases pigments, photosynthesis, seed oil, pod number, and yield, revealing a new way that light boosts crop productivity. ABSTRACT Light signaling coordinates plant development with metabolism, but the link between photoreceptors and ...

An alfalfa MYB71‐centered activation–attenuation module fine‐tunes redox homeostasis and drought tolerance in Medicago sativa

open access: yesJournal of Integrative Plant Biology, EarlyView.
In alfalfa, the transcription factor MsMYB71 activates the peroxiredoxin Q gene MsPrxQ, which helps remove harmful reactive oxygen species and improves drought tolerance. The WD40‐repeat protein MsPRL1 and the Cullin‐family scaffold protein MsCUL4 interact with and limit MsMYB71 accumulation and activity in an activation‐attenuation mechanism ...

Beyond single cells: Ten years of commercial lattice light‐sheet microscopy

open access: yesJournal of Microscopy, EarlyView.
Abstract Lattice light‐sheet microscopy (LLSM) enables gentle, rapid, volumetric fluorescence imaging of living biological systems. The technique employs Bessel beam interference to produce a light‐sheet which retains its thickness over a relatively large field‐of‐view compared to other light‐sheets.

Visualising Physcomitrium patens protoplasts with full‐rotation soft X‐ray tomography

open access: yesJournal of Microscopy, EarlyView.
Abstract Soft X‐ray tomography (SXT) is a label‐free, high‐resolution imaging modality that is optimal for 3D visualisation of whole hydrated cells. Although SXT has been extensively used to study remodelling in more than 130 mammalian cell lines, its application to plants remains largely unexplored. In this study, we present the first approach at full‐
