Plant laccases (LACs) play a vital role in lignification and participate in multiple biotic/abiotic stress responses. However, little is known about their role in lignin deposition and stress resistance in cultivated peanut (Arachis hypogaea L.). In this study, 80 putative peanut laccase genes (AhLACs) were identified and clustered into seven distinct phylogenetic groups. While the AhLAC members of group VI were lost, a novel specific group VIII was discovered in peanut. AhLACs within same group generally have similar gene structures and protein motif organizations. Expression pattern and subcellular cellular analysis revealed that AhLAC63 is a candidate gene involved in lignification and abiotic stress response. In addition, introducing AhLAC63 into the Arabidopsis laccase mutant (lac4 lac11) restored its lignin contents and abiotic stress tolerance. Moreover, the overexpression of AhLAC63 significantly altered phenylpropanoid metabolism flux and increased lignin content in peanut hairy roots. This study not only enables the further exploration of LAC biological functions in peanut, but also provides new gene resources for improving stress resistance in crops.

Background: As an opportunistic bacterial pathogen, Klebsiella pneumoniae (KP) is prone to causing a spectrum of diseases in rabbits when their immune system is compromised, which poses a threat to rabbit breeding industry. Bacillus coagulans (BC), recognized as an effective probiotic, confers a variety of benefits including anti-inflammatory and antioxidant properties.
Aim: The purpose of this study was to investigate whether dietary BC can effectively alleviate hepatic injury caused by KP.

In plants, microRNAs (miRNAs) participate in complex gene regulatory networks together with the transcription factors (TFs) in response to biotic and abiotic stresses. To date, analyses of miRNAs-induced transcriptome remodeling are at the whole plant or tissue levels. Here, Arabidopsis's ABA-induced single-cell RNA-seq (scRNA-seq) is performed at different stages of time points-early, middle, and late.

Objectives: Our aim was to evaluate the comparative effects of sertraline and vortioxetine against stress-induced brain injury in rats.
Methods: The rats were assigned to a nonstress group (NSG), stress-treated control (StC), sertraline + stress (SSt), and vortioxetine + stress (VSt) groups. Sertraline and vortioxetine (10 mg/kg) were given orally by gavage to the SSt and VSt groups.

Fatty acid binding proteins (FABPs) are a class of small molecular mass intracellular lipid chaperone proteins that bind to hydrophobic ligands, such as long-chain fatty acids. FABP5 expression was significantly upregulated in the N-methyl-d-aspartic acid (NMDA) model, the microbead-induced chronic glaucoma model, and the DBA/2J mice. Previous studies have demonstrated that FABP5 can mediate mitochondrial dysfunction and oxidative stress in ischemic neurons, but the role of FABP5 in oxidative stress and cell death in retina NMDA injury models is unclear.
