Pale-green phenotype of atl31atl6 double mutant leaves is caused by disruption of 5-aminolevulinic acid biosynthesis in Arabidopsis thaliana.

PLoS ONE, 2015
Arabidopsis ubiquitin ligases ATL31 and homologue ATL6 control the carbon/nitrogen nutrient and pathogen responses. A mutant with the loss-of-function of both atl31 and atl6 developed light intensity-dependent pale-green true leaves, whereas the single ...

Time‐series multi‐omics analysis of micronutrient stress in Sorghum bicolor reveals iron and zinc crosstalk and regulatory network conservation

Plant Biology, EarlyView.
Overlap between Fe and Zn responsive gene regulatory networks (GRNs) were found, indicative of micronutrient crosstalk, and conservation of root and leaf GRNs and genes suggests strong constraint on homeostasis networks in plants. Abstract Micronutrient stress impacts growth, biomass production, and grain yield in crops.

Structural and Functional Characterisation of a Metagenome‐Derived CYP108D18 Reveals an Unusual Dioxygen‐Bound State and Selective Hydrocarbon Hydroxylation

Microbial Biotechnology, Volume 19, Issue 10, October 2026.
CYP108D18, identified from a hot spring metagenome, catalyses selective phenylcyclohexane hydroxylation. This P450 has an exceptionally low substrate‐bound heme redox potential. Crystal structures revealed an unusual dioxygen‐bound substrate‐free form and a persistent open active site upon substrate binding.

5-Aminolevulinic acid-mediated sonosensitization of rat RG2 glioma cells in vitro

, 2016
Sonodynamic therapy (SDT) is a promising technique based on the ability of certain substances, called sonosensitizers, to sensitize cancer cells to non-thermal effects of low-energy ultrasound waves, allowing their destruction.

Wavelength Dependency of Photodynamic Effects After Sensitization with 5-Aminolevulinic Acid In Vitro and In Vivo [PDF]

, 1995
A promising new therapeutic modality for skin cancer, administration of the heme precursor 5-aminolevulinic acid followed by light irradiation, is known as photodynamic therapy.

Simulated daylight versus conventional PDT for mild to moderate actinic keratoses: A randomized controlled trial

Journal of the European Academy of Dermatology and Venereology, Volume 40, Issue 10, Page 1713-1720, October 2026.
This single‐centre, randomized controlled trial showed that simulated daylight photodynamic therapy (SDL‐PDT, n = 785 lesions) was less effective than conventional photodynamic therapy (C‐PDT, n = 673 lesions) in treating mild to moderate actinic keratoses with 1‐year clearance rates of 71.0% for SDL‐PDT versus 85.3% for C‐PDT (p < 0.001). However, SDL‐

Divergent roles of ent‐kaurene oxidase paralogs in rice momilactone biosynthesis

Journal of Integrative Plant Biology, Volume 68, Issue 10, Page 3776-3789, October 2026.
Rice contains a five‐gene tandem array of genes encoding members of the ent‐kaurene oxidase (KO) family, with OsKOL4 and OsKOL5 playing divergent roles in momilactone metabolism, but both acting in the production of antifungal and antibacterial phytoalexins, which are important for disease resistance.

Effect of 5-aminolevulinic acid on yield and quality of lettuce in sunlit greenhouse [PDF]

, 2016
The role of 5-aminolevulinic acid (ALA) as a precursor of chlorophyll and heme is well documented. Low concentration of exogenous ALA has been found to regulate plant growth and increase crop yield, but there is little information on how ALA influences ...

Relaxin‐2: Shaping the Proteomic Landscape of Skeletal Muscle Physiology, Glucose Trafficking, and Mitochondrial Function in Rat

The FASEB Journal, Volume 40, Issue 18, 30 September 2026.
Cardioprotective hormone relaxin‐2 showed relevant effects on rat skeletal muscle by altering proteins linked to muscle function, regeneration, differentiation, mitochondrial function, glucose metabolism, and structural integrity and organization. Specifically, relaxin‐2 reduced the expression of 95 proteins, increased 32, and elicited unique proteins ...
