Induction and phenotype analysis of autotetraploids of Morus Mongolica

BMC Plant Biology
Background Morus mongolica holds significant value in medicinal applications, livestock fodder production, and ecological restoration. Although polyploidization is well-documented in plants for enhancing stress tolerance and altering nutrient composition,

Identification and expression pattern analysis of the Hydroxycinnamoyl transferase gene family and function of StHCT6 in the potato

Frontiers in Plant Science
IntroductionHydroxycinnamoyl transferase (HCT) is a key enzyme in the plant phenylpropanoid biosynthetic pathway, involved in plant growth, development, and responses to biotic and abiotic stresses.

Copper/Zinc Superoxide Dismutase from the Crocodile Icefish Chionodraco hamatus: Antioxidant Defense at Constant Sub-Zero Temperature

Antioxidants, 2020
In the present study, we describe the purification and molecular characterization of Cu,Zn superoxide dismutase (SOD) from Chionodraco hamatus, an Antarctic teleost widely distributed in many areas of the Ross Sea that plays a pivotal role in the ...

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Transcriptome and metabolome reveal the primary and secondary metabolism changes in Larix gmelinii seedlings under abiotic stress

BMC Plant Biology
Background Larix gmelinii is an excellent stress resistant coniferous tree species with a wide distribution and important economic and ecological value. However, at seedling stage, L.

Optimized Blends of Polyhalite and Muriate of Potash Under Reduced Potassium Rate Are Associated with Enhanced Tuber Starch Content and Up-Regulation of Starch Biosynthetic Genes in Potato

Agriculture
Excessive potassium (K) application in potato production impairs tuber quality. To develop a rational K fertilization strategy using polyhalite (POLY4), we conducted two field trials (2022, 2023) with potato cultivar ‘Dafeng No. 10’.

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

FEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Cold adaptation does not alter ATP homeostasis during cold exposure inDrosophila melanogaster [PDF]

, 2018
In insects and other ectotherms, cold temperatures cause a coma resulting from loss of neuromuscular function, during which ionic and metabolic homeostasis are progressively lost.

Genotypic Differences in Potato Yield and Starch Content Response to Potassium Fertilization Under Drought Stress

Plants
Drought stress constrains potato (Solanum tuberosum L.) production, and potassium (K) fertilization may alleviate it, but genotype-dependent responses remain unclear.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...
