To investigate the etiopathogenesis of fatty liver hemorrhagic syndrome (FLHS) and the protective effects of soybean lecithin against FLHS in laying hens, 135 healthy 300-day-old Hyline laying hens were randomly divided into groups: control (group 1), diseased (group 2), and protected (group 3). Each group contained 45 layers with 3 replicates. The birds in these 3 groups were fed a control diet, a high-energy/low-protein (HELP) diet or the HELP diet supplemented with 3% soybean lecithin instead of maize. The fat percent in the liver was calculated...

A series of novel sulfonylurea benzothiazolines was designed by splicing active groups and bioisosterism. A solvent-free synthetic route was developed for the sulfonylurea benzothiazoline derivatives via the cyclization and carbamylation. All compounds were characterized by IR, ¹H-NMR, (13)C-NMR, HRMS. The biological activity tests indicated the compounds could protect maize against the injury caused by chlorsulfuron to some extent. The molecular docking result showed that the new compound competed with chlorsulfuron to bind with the herbicide target enzyme active site to attain detoxification...

The few-celled female gametophyte, or embryo sac, of flowering plants is not easily accessible as it is buried within the sporophytic tissues of the ovule. Nevertheless, it has become an attractive model system to study the molecular mechanisms underlying patterning and cell type specification, as well as fertilization of the two female gametes, the egg and the central cell. While female gametes, zygotes, and early embryos can be manually isolated from the embryo sacs in maize, wheat, tobacco, and rice by micromanipulation, this approach had been considered impossible for the much smaller embryo sac of the model plant Arabidopsis thaliana...

The plant life cycle is characterized by the alternation of generations between genetically active diploid sporophytes and haploid gametophytes. The gametophytes of flowering plants are sexually dimorphic. While the male gametophyte consists of only three cells (two sperm and a vegetative cell) and is released by the parent sporophyte, the female gametophyte (or embryo sac) is more complex and remains imbedded within diploid sporophyte tissues. In maize, the female gametophyte is embedded in a large ovule surrounded with multiple nucellar cell layers impeding live-cell imaging approaches to study embryo sac functions...

Visualization of the intact embryo sac within the ovular/gynoecial tissues and clear identification of cell types can be logistically difficult and subject to interpretation. Cellular marker technologies have been available for the embryo sac, but have typically labeled only one cell type in a particular line. Here, we describe techniques for simultaneous labeling each cell type in the embryo sac and visualization methods for such in Arabidopsis, soybean, maize, and sorghum.

Sorption of organic compounds on fresh black carbons (BCs) can be greatly attenuated in soil over time. We examined herein the changes in surface properties of maize straw-derived BCs (biochars) after aged in a black soil and their effects on the sorptive behaviors of naphthalene, phenanthrene and 1,3-dinitrobenzene. Dissolved fulvic and humic acids extracted from the soil were used to explore the role of dissolved organic carbon (DOC) in the aging of biochars. Chromatography analysis indicated that DOC molecules with relatively large molecular weight were preferentially adsorbed on the biochars during the aging processes...

Soil organic carbon (SOC) is a major component in the global carbon cycle. Yet how input of plant litter may influence the loss of SOC through a phenomenon called priming effect remains highly uncertain. Most published results about the priming effect came from short-term investigations for a few weeks or at the most for a few months in duration. The priming effect has not been studied at the annual time scale. In this study for 815 days, we investigated the priming effect of added maize leaves on SOC decomposition of two soil types and two treatments (bare fallow for 23 years, and adjacent old-field, represent stable and relatively labile SOC, respectively) of SOC stabilities within each soil type, using a natural 13C-isotope method...

Stress drought is an important abiotic factor that leads to immense losses in crop yields around the world. Strategies are urgently needed to help plants adapt to drought in order to mitigate crop losses. Here we investigated the bioprotective effects of inoculating corn grown under drought conditions with two types of plant growth-promoting rhizobacteria (PGPR), A. brasilense, strain SP-7, and H. seropedicae, strain Z-152. Plants inoculated with the bacteria were grown in a greenhouse with perlite as a substrate...

To ensure food security, maize (Zea mays) is a model crop for understanding useful traits underlying stress resistance. In contrast to foliar biochemicals, root defenses limiting the spread of disease remain poorly described. To better understand below-ground defenses in the field, we performed root metabolomic profiling and uncovered unexpectedly high levels of the sesquiterpene volatile β-selinene and the corresponding non-volatile antibiotic derivative, β-costic acid. The application of metabolite-based quantitative trait loci (mQTL) mapping using bi-parental populations, genome wide association studies, and near-isogenic lines (NILs) enabled the identification of terpene synthase 21 (ZmTps21) on chromosome 9 as a β-costic acid pathway candidate gene...

Fusion of solubility-enhancing tag is frequently used for improving soluble production of target protein in Escherichia coli. The Arabidopsis tetraticopeptide domain-containing thioredoxin (TDX) has been documented to exhibit functions of disulfide reductase, foldase chaperone, and holdase chaperone. Here, we identified that fusion of rice TDX with the smaller size increased soluble expression levels of three fluorescent proteins with different fluorophores in the E. coli strain BL21(DE3) or the Rosetta (DE3) strain with coexpression of six rare tRNAs, but decreased conformational quality of certain fluorescent proteins, as comparison with the His6-tagged ones...
