Leaf C:P ratio as a universal indicator of photosynthesis in subtropical woody species: Stoichiometric thresholds and metabolic trade‐offs

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric ratios of carbon (C), nitrogen (N) and phosphorus (P) serve as important indicators for assessing nutrient balance in forest ecosystems, but their relationships with photosynthetic dynamics require deeper characterization.

Degradable versus inert microplastics: Effects on soil organic carbon persistence via microbial drivers in an agroecosystem

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Microplastics (MPs) are widespread in terrestrial ecosystems, raising global concerns that they may disrupt soil organic carbon (SOC) cycling and undermine agroecosystem contributions to climate mitigation.

Conservative roots confer a larger microbial carbon pump efficacy than acquisitive roots by regulating microbial life‐history strategy

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Root activity creates unique microbial hotspots in the rhizosphere by influencing the metabolic activities of surrounding soil microorganisms, profoundly regulating the dynamics of soil organic carbon (SOC). However, how root economic strategies affect the formation and

Mycotoxins‐contaminated wheat matrices bioconversion by Tenebrio molitor larvae (Coleoptera: Tenebrionidae)

Insect Science, EarlyView.
Larval development time, ADG, survival rate and substrate consumption were not negatively affected by the levels of mycotoxins contamination Larvae excreted most of the ingested DON and its derivatives through exuviae and frass The mycotoxin accumulation rates observed in larvae were always below the current legal limits for livestock feed Abstract ...

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

Insect Science, EarlyView.
RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

A plastidic starch biosynthetic pathway defines columella-specific carbon metabolism in rice root tips

Frontiers in Plant Science
Starch biosynthesis in rice (Oryza sativa) is precisely regulated in an organ-specific manner, but the molecular mechanism operating this pathway in root-tip columella cells has remained unclear.

Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

Integrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Regulation of starch biosynthesis in Arabidopsis thalinan

, 2015
Starch is an important carbohydrate in higher plants and is widely used in food and non-food industries. Starch is synthesized in plastids through the actions of starch synthases (SS), starch branching enzymes (SBE), and starch debranching enzymes (DBE),
