Structure, Synthesis, and Bioassays of Sex Pheromone for (Lepidoptera: Crambidae).

The leaf skeletonizer, (Lepidoptera: Crambidae), is a serious insect pest of teak () in China. The application of insect pheromones is widely applied as an environmentally friendly technology for integrated pest management (IPM). In the present study, crude extracts of sex pheromone glands of calling females were collected and then analyzed using gas chromatography/electroantennographic detection (GC/EAD) and gas chromatography-mass spectrometry (GC-MS).

First Report of Causing Foliar Powdery Mildew on in Guangdong Province, China.

Linn is an evergreen and facultative root hemiparasitic tree. It is attached to host roots through haustorium to withdraw water and nutrients. Its aromatic heartwood, honored as "Green Gold", is widely used in perfumes, incense, medicine, and skin cancer prevention (Sandeep and Manohara 2019, Polaiah et al.

Nitrogen rather than carbon released by litter decomposition mediates nutrient relationships in a multispecies forest plantation with hemiparasite.

Hemiparasitic plants influence community composition by altering nutrient cycling. Although hemiparasites can deplete a host's nutrients via parasitism, their potentially positive effects on nutrient return to multispecies communities remain unclear. We used C/N-enriched leaf litter of the hemiparasite sandalwood (Santalum album, Sa) and two N-fixing hosts of acacia (Acacia confusa, Ac) and rosewood (Dalbergia odorifera, Do), either as a single-species or mixed-species litter, to elucidate nutrient return by litter decomposition in an acacia-rosewood-sandalwood mixed plantation.

Ultrathin Two-Dimensional BiOCl-Bi S -Cu S Ternary Heterostructures with Enhanced LSPR effect for NIR Photonic Bacterial Disinfection.

Photonic disinfection, particularly near-infrared (NIR) light triggered antibacterial, has emerged as a highly promising solution for combating pathogenic microbes due to its spatiotemporal operability, safety, and low cost of apparatus. However, it remains challenging to construct NIR-responsive antibacterial agents with high light-converting efficacy and elucidate synergistic mechanisms. In this work, ultrathin two-dimensional (2D) BiOCl-Bi S -Cu S ternary heterostructures that can efficiently kill drug-resistant bacteria were synthesized by doping 0D Bi S and Cu S nanoparticles in the 2D BiOCl nanosheets via a facile one-pot hydrothermal method.

Heterojunction structured BiOCl-BiS nanosheets as mitochondria-targeted near-infrared photothermal and photodynamic therapy agent.

Mitochondria-targeted phototherapy, especially combined photothermal therapy (PTT) and photodynamic therapy (PDT), has been regarded as an attractive strategy for the treatment of tumor. In this study, a facile approach to prepare two-dimensional (2D) BiOCl-BiS nanostructures was developed, where BiS quantum dots were doped in/on the ultrathin BiOCl nanosheets, forming a p-n heterojunction. The BiOCl-BiS shows favorable photothermal conversion efficiency (32%) and synergistically reactive oxygen species (ROS) generating capability under near-infrared (NIR) irradiation.

Analysis of Rac/Rop Small GTPase Family Expression in L. and Their Potential Roles in Drought Stress and Hormone Treatments.

Plant-specific Rac/Rop small GTPases, also known as Rop, belong to the Rho subfamily. Rac proteins can be divided into two types according to their C-terminal motifs: Type I Rac proteins have a typical CaaL motif at the C-terminal, whereas type II Rac proteins lack this motif but retain a cysteine-containing element for membrane anchoring. The gene family participates in diverse signal transduction events, cytoskeleton morphogenesis, reactive oxygen species (ROS) production and hormone responses in plants as molecular switches.

Host root exudates initiate a foraging preference by the root parasite Santalum album.

Haustoria of root-parasitic plants draw nutrients from the roots of host species. While recent studies have assessed host preferences of parasitic plants, how root-exuded chemicals can mediate host tropism and selection by root-parasitic plants is poorly understood. Under greenhouse conditions, we performed two pot experiments to determine whether the root parasite Santalum album selectively forages for superior hosts (N2-fixing Acacia confusa Merr.

Combined transcriptome and metabolome analysis of Nerium indicum L. elaborates the key pathways that are activated in response to witches' broom disease.

The yellowhorn AGL transcription factor gene XsAGL22 contributes to ABA biosynthesis and drought tolerance in poplar.

Regulation of abscisic acid (ABA) biosynthesis helps plants adapt to drought stress, but the underlying molecular mechanisms are largely unclear. Here, a drought-induced transcription factor XsAGL22 was isolated from yellowhorn (Xanthoceras sorbifolium Bunge). Yeast one-hybrid and electrophoretic mobility shift assays indicated that XsAGL22 can physically bind to the promoters of the ABA biosynthesis-related genes XsNCED6 and XsBG1, and a dual-luciferase assay showed that XsAGL22 activates the promoters of the later two genes.

Low Air Drag Surface via Multilayer Hierarchical Riblets.

Riblets inspired by shark skin exhibit a great air drag reduction potential in many industries, such as the aircraft, energy, and transportation industries. Many studies have reported that blade riblets attain the highest air drag reduction ability, with a current limit of ∼11%. Here, we propose multilayer hierarchical riblets (MLHRs) to further improve the air drag reduction ability.

Co-existence of Rhizobia and Diverse Non-rhizobial Bacteria in the Rhizosphere and Nodules of Seedlings Inoculated with -Like and Like Strains.

Rhizobia induce root nodules and fix atmospheric N for most legume species in exchange for carbon. However, the diverse endophytic non-rhizobial bacteria in legume nodules that co-exist with rhizobia are often ignored because they are difficult to cultivate using routine cultivation approaches. To enhance our understanding of the incidence and diversity of legume-bacteria associations, a high-throughput sequencing analysis of bacterial 16S rRNA genes was used to examine the bacterial community in the rhizospheres and root nodules of seedlings that were uninoculated or inoculated with H255, like HT221, or like H022238, in two growth media (nitrogen [N]-supplied soil or N-omitted potting mix).

In Situ Observation of Dynamic Wetting Transition in Re-Entrant Microstructures.

Re-entrant microstructures exhibit excellent wetting stability under different pressure levels, but the underlying mechanism determined by wetting transition behavior at the microscale level remains unclear. We propose the "wetting chip" method for in situ assessment of the dynamic behavior of wetting transition in re-entrant microstructures. High sag and transverse depinning were observed in re-entrant microstructures.
