In this paper, a full-length cDNA-encoding cytosolic nicotinamide adenine dinucleotide phosphatedependent isocitrate dehydrogenase was isolated from maize and named ZmICDH. Analysis of the deduced protein sequence revealed that this gene had considerably high homologies with other plant ICDH genes such as those from rice, Arabidopsis and poplar. The gene was transcribed in all tissues tested, with the highest amount of transcript in root. Subcellular localization results indicated that ZmICDH was localized in cytosol. In an attempt to further understand the role of ZmICDH in maize, the functional characterization of the gene was conducted. The results indicated that the expression of ZmICDH was induced by drought and salt stresses. ZmICDH enhanced salt tolerance in transgenic Arabidopsis.

The rice nucleotide-binding site–leucine-rich repeat (NBS-LRR)-encoding resistance (R) gene Pi9 confers broad-spectrum resistance to the fungal pathogen Magnaporthe oryzae. The Pi9 locus comprises many NBS-LRR-like genes and is an ancient locus that is highly conserved in cultivated and wild rice species. To understand the genetic variation and molecular evolutionary mechanism of the Pi9 alleles in different rice species, we studied five AA genome Oryza species including two cultivated rice species (Oryza sativa and Oryza glaberrima) and three wild rice species (Oryza nivara, Oryza rufipogon, and Oryza barthii). A 2.9-kb fragment spanning the NBS-LRR core region of the Pi9 gene was amplified and sequenced from 40 accessions. Sequence comparison revealed that the Pi9 alleles had an intermediate-diversified nucleotide polymorphism among the AA genome Oryza species. Sequence variations were more abundant in the LRR region than in the NBS region, indicating that the LRR region has played a more important role for the evolution of the Pi9alleles. Furthermore, positive selection was found to be the main force promoting the divergence of the Pi9 alleles,especially in the LRR region. Our results reveal the characteristics and evolutionary dynamics of the Pi9 alleles among the two cultivated and three wild rice species.

The present study was conducted to determine the effects of L-carnosine (LC) and/or alpha-lipoic acid (ALA) supplementation on growth performance, blood thyroid hormones and lipid profiles in finishing pigs. A total of 40 (Landrace×Yorkshire) pigs with an initial body weight of 57.93±3.14 kg were randomly allocated to 4 experimental diets using a 2×2 factorial arrangement with 2 LC supplemental levels (0 or 0.1%) and 2 ALA supplemental levels (0 or 0.03%) in basal diets. The results showed that pigs fed LC-supplemented diets increased final live weight, average daily gain, and average daily feed intake compared to those of pigs fed without LC-supplemented diets (p<0.05). Dietary supplementation with ALA did not affect the growth performance and carcass traits of pigs (p>0.05). Additionally, LC supplementation increased serum triiodothyronine, thyroxine levels, and ALA supplementation increased serum triiodothyronine levels (p<0.05). Serum total cholesterol and triglycerides levels were significantly decreased in LC and ALA supplemented groups, respectively (p<0.05). Moreover, serum low density lipoprotein cholesterol levels were lower in the ALAsupplemented groups than those of pigs fed without ALA-supplemented diets (p<0.05). However, no significant LC×ALA interaction effect on growth performance, blood thyroid hormones and lipid profiles was found. This study suggested that dietary supplementation of LC resulted in better growth performance compared to that of ALA supplementation. L-carnosine and/or ALA supplementation positively modified blood lipid profiles, which may have the potential to prevent cardiovascular diseases.

Dihydroxyacid dehydratase (DHAD), encoded by ILV3, catalyses the third step in the biosynthetic pathway of branchedchain amino acids (BCAAs), which include isoleucine (Ile), leucine (Leu), and valine (Val). Enzymes involved in BCAA biosynthesis exist in bacteria, plants, and fungi but not in mammals and are therefore attractive targets for antimicrobial or herbicide development. In this study, three paralogous ILV3 genes (FgILV3A, FgILV3B, and FgILV3C) were identified in the genome of Fusarium graminearum, the causal agent of Fusarium head blight (FHB). Deletion of FgILV3A alone or combined with FgILV3B or FgILV3C indicated an important role for FgILV3A in BCAA biosynthesis. FgILV3A deletion mutants lost the ability to grow on medium lacking amino acids. Exogenous supplementation of 1 mM Ile and Val rescued the auxotrophy of ΔFgIlv3A, though 5 mM was required to recover the growth defects in ΔFgIlv3AB and ΔFgIlv3AC strains, indicating that FgIlv3b and FgIlv3c exhibit redundant but accessory roles with FgIlv3a in BCAA biosynthesis. The auxotrophy of ΔFgIlv3A resulted in pleiotropic defects in aerial hyphal growth, in conidial formation and germination, and in aurofusarin accumulation. In addition, the mutants showed reduced virulence and deoxynivalenol production. Overall, our study demonstrates that FgIlv3a is crucial for BCAA biosynthesis in F. graminearum and a candidate fungicide target for FHB management.

Glutamate receptors (GluRs) are sensors ofextracellular signals; they play important roles in the regulationof multiple physiological and developmental processes ineukaryotes. However, their functional roles in fruit trees arelargely unknown. Here, based on the pear genome database,which was established in this lab, we identified 34 PbGLRsin pear (Pyrus bretschneideri Rehd), and they were dividedinto four groups by phylogenetic analysis. In comparisonswith other groups, phylogenetic analyses and structuralinformation of the PbGLRs in group 3 suggest that thesegenes underlie specific characteristics. Among the ten genesin group 3, we observed that the expression of PbGLR3.3increased gradually during pollen germination and continuousgrowth, indicating that this gene might play a vital role in thedevelopment of pear pollen tubes. Using a combination ofantisense oligodeoxy nucleotides and Ca2+-sensitive fluorescentprobe methods, we verified that PbGLR3.3 participates in DSer-elicited intracellular Ca2+ signaling and Ca2+ regulationof growth in pear pollen tubes.

The oceans are rich in diverse microorganisms, animals, and plants. This vast biological complexity is a major source of unique secondary metabolites. In particular, marine fungi are a promising source of compounds with unique structures and potent antibacterial properties. Over the last decade, substantial progress has been made to identify these valuable antibacterial agents. This review summarizes the chemical structures and antibacterial activities of 223 compounds identified between 2012 and 2023. These compounds, effective against various bacteria including drug-resistant strains such as methicillin-resistant Staphylococcus aureus, exhibit strong potential as antibacterial therapeutics. The review also highlights the relevant challenges in transitioning from drug discovery to product commercialization. Emerging technologies such as metagenomics and synthetic biology are proposed as viable solutions. This paper sets the stage for further research on antibacterial compounds derived from marine fungi and advocates a multidisciplinary approach to combat drug-resistant bacteria.

InP-based hetero-junction bipolar transistors (HBTs) are attractive for various millimeter-wave and terahertz electronics due to their ultrahigh frequency performance. Therefore, the study of their irradiation reliability is extremely urgent. In this work, 2 MeV proton irradiation experiment has been carried out on self-fabricated N+Np+ InP/InGaAs hetero-junction. The degradation mechanisms have systematically been studied after exposure to protons of 5 × 1013 H+/cm2. The voltage range of recombination current at low forward bias has been largely expanded from 0-0.2 V to 0–0.6 V. Furthermore, the interface states properties have been characterized by utilizing the frequency-dependent conductance technique, the interface states density (Dit) has increased from approximately 9.02 × 1012 cm-2 eV-1–1.99 × 1013 cm-2 eV-1 to 9.51 × 1012 cm-2 eV-1–2.00 × 1013 cm-2 eV-1 after irradiation. The study would be great significance for understanding the evolution of proton irradiation on relative devices.
