The appearance of scalp high-frequency oscillations is associated with poor seizure control in pediatric epilepsy patients.

Objective: Epilepsy treatment with anti-seizure medications (ASMs) is based on careful assessment of the balance between the likelihood of further seizures and the risk of side effects of treatment. However, there is currently no established biomarker to ascertain seizure control status with ASMs. High-frequency oscillations (HFOs), transient bursts of EEG activity with frequencies beyond 80 Hz, are a new and promising noninvasive epilepsy biomarker.

Disruption of aldehyde dehydrogenase decreases cell wall-bound p-hydroxycinnamates and improves cell wall digestibility in rice.

In grass cell walls, ferulic acid (FA) serves as an important cross-linker between cell wall polymers, such as arabinoxylan (AX) and lignin, affecting the physicochemical properties of the cell walls as well as the utilization properties of grass lignocellulose for biorefinering. Here, we demonstrate that hydroxycinnamaldehyde dehydrogenase (HCALDH) plays a crucial role in the biosynthesis of the FA used for cell wall feruloylation in rice (Oryza sativa). Bioinformatic and gene expression analyses of aldehyde dehydrogenases (ALDHs) identified two rice ALDH subfamily 2C members, OsHCALDH2 (OsALDH2C2) and OsHCALDH3 (OsALDH2C3), potentially involved in cell wall feruloylation in major vegetative tissues of rice.

The exp2 gene, which encodes a protein with two zinc finger domains, regulates cap expansion and autolysis in Coprinopsis cinerea.

Cap expansion in agaricoid mushroom species is an important event for sexual reproduction because meiosis occurs in basidia under the cap, and basidiospores can be released by opening the cap. However, molecular mechanisms underlying cap expansion in basidiomycetes remain poorly understood. We aimed to elucidate the molecular mechanisms of cap expansion in basidiomycetes by analyzing the unique cap-expansionless UV mutant #13 (exp2-1) in Coprinopsis cinerea.

Peroxisomal 4-coumaroyl-CoA ligases participate in shikonin production in Lithospermum erythrorhizon.

4-Coumaroyl-CoA ligase (4CL) is a key enzyme in the phenylpropanoid pathway, which is involved in the biosynthesis of various specialized metabolites such as flavonoids, coumarins, lignans, and lignin. Plants have several 4CLs showing divergence in sequence: Class I 4CLs involved in lignin metabolism, Class II 4CLs associated with flavonoid metabolism, and atypical 4CLs and 4CL-like proteins of unknown function. Shikonin, a Boraginaceae-specific specialized metabolite in red gromwell (Lithospermum erythrorhizon), is biosynthesized from p-hydroxybenzoic acid, and the involvement of 4CL in its biosynthesis has long been debated.

SULTR2;1 Adjusts the Bolting Timing by Transporting Sulfate from Rosette Leaves to the Primary Stem.

Sulfur (S) is an essential macronutrient for plant growth and metabolism. SULTR2;1 is a low-affinity sulfate transporter facilitating the long-distance transport of sulfate in Arabidopsis. The physiological function of SULTR2;1 in the plant life cycle still needs to be determined.
