Summary: This review article discusses the potential ecological functions of the homoterpenes DMNT and TMTT, which are volatile products of plant metabolism. These compounds have been reported in various plant taxa and tissues, and they may have roles in plant-arthropod interactions. DMNT and TMTT are important constituents of floral scents and may attract pollinators, although there is limited experimental evidence for this. They are also released by plants in response to arthropod feeding or damage, and may play a role in herbivore-induced plant volatile blends. The authors conclude by highlighting the need for further research on the ecological functions of DMNT and TMTT and their potential use in agriculture.

Summary: The study investigates the role of (E)-beta-famesene (EBF) in mediating interactions between plants, aphids, and natural enemies. The researchers found that both larvae and adults of the aphid predator hoverfly are attracted to EBF. They also identified a neuron in the antenna of adult hoverflies that responds to EBF. Furthermore, they discovered that odorant receptor EcorOR3 and odorant-binding protein EcorOBP15 play a role in detecting EBF. The findings suggest potential applications in integrated aphid management approaches.

Summary: Soybean, a valuable crop, is often damaged by insect pests or pathogens. To protect soybean in an environment- or human-friendly way, the study focuses on herbivore-induced plant volatiles that repel insects. The gene responsible for the biosynthesis of (E)-beta-ocimene, an anti-insect compound, was identified in soybean. Transgenic soybean with this gene showed improved resistance to insect attack, suggesting its potential use in anti-insect soybean improvement.

Summary: This study found that (E)-beta-ocimene, a terpenoid compound, enhances resistance of sea buckthorn to RBO. The up-regulator HrTPS12 regulates the synthesis of (E)-beta-ocimene, and overexpression of HrTPS12 increases defense against RBO. These findings provide insights for developing plant-based insect repellents.

Summary: This study comprehensively investigated the atmospheric oxidation of (E)-beta-farnesene initiated by OH radical. It was found that OH addition reactions dominate the initial reactions, leading to the production of various oxidized compounds. This research is of great significance for understanding the atmospheric fate of (E)-beta-farnesene and the contributions of sesquiterpenes to SOA formation.

Summary: This study investigates the transcriptional changes and molecular mechanisms in wild pear trees infested with the polyphagous herbivore Spodoptera litura. It identifies differentially expressed genes and reveals the activation of phytohormonal signaling networks in response to herbivore attack. The study also discovers a new putative gene involved in the synthesis of (E)-beta-ocimene and demonstrates its role in herbivore-induced plant defenses.

Summary: Exposure to volatile compounds from host plants can increase male sexual success in certain tephritid fruit flies. This study found that male Anastrepha fraterculus flies exhibited intensified courtship behavior and greater copulatory success when exposed to volatiles from guava fruit, guava essential oil, moradillo essential oil, or lemon essential oil. The responsible compounds were identified as (E/Z)-beta-ocimene and (R)-limonene, and a dose-dependent effect was observed. These findings have implications for the development of the sterile insect technique in this species.

Summary: This study aimed to maximize the flux of farnesyl diphosphate to farnesene biosynthesis in Saccharomyces cerevisiae. Through screening and genetic engineering, a high alpha-farnesene producing yeast strain was developed, reaching a production level of 10.4 g/L. Various strategies were employed, such as overexpressing key enzymes and optimizing gene expression, to achieve the significant improvement in farnesene production.

Summary: Seed dispersal plays a crucial role in the survival of short-lived seeds of Aquilaria sinensis in tropical southwest China. Vespa hornets attract most seeds by consuming elaiosomes and depositing them in damp shade, facilitating germination 166 meters away from the parent tree. Rapid seed dispersal is achieved through the release of volatile compounds that attract hornets and serve as an indirect defense mechanism for the species.

Summary: The study shows that the ratio of Germacrene D (GD) to (E)-beta-farnesene (E beta F) in Tanacetum cinerariifolium flowers changes with developmental stages, and this change is correlated with the tissue distribution. This suggests that the emissions of different E beta F/GD ratios might be regulated by their tissue distribution.

Summary: The study found that plants growing under low water availability benefited specialist herbivores like Pieris rapae, but were detrimental to most other herbivores. Water availability impacted plant quality and multi-trophic interactions, with reduced water availability leading to higher survival rates for Pieris rapae larvae.

Summary: IPBES confirmed a decline in abundance and diversity of pollinators in Mexico, with insufficient data available. Despite the identification of 2063 bee species and 57 related studies, data for endangered hummingbirds, pollinator bats, and over 1000 bee species is limited. Mexico has made significant efforts in recent years to improve policies and programs for pollinator conservation, but further research on biodiversity and policy impacts is needed.

Summary: Herbivore-induced plant volatiles (HIPVs) are an indirect plant defense mechanism that attracts natural enemies to attack infested plants, while also affecting the behavior of herbivores. This study found that the oriental fruit moth (G. molesta) showed positive responses to HIPVs emitted by pear trees, and preferred to lay eggs on infested pear shoots. These results suggest that HIPVs not only recruit natural enemies, but also attract G. molesta females. Therefore, it is important to investigate the responses of G. molesta females to HIPVs in the field before using them for pest management.

Summary: This study proposes an AlON/HfZrOx (HZO)/HfO2 stack with postdeposition annealing (PDA) process at 400 degrees C to implement BEOL compatible ferroelectric (FE) capacitors. The interface engineering and PDA process enhance the performance of the capacitors, allowing for higher bit storage and better stability. The FE capacitors demonstrate wake-up free behavior and the ability to operate with 3 bits per cell and 8 stable states, outperforming other FE capacitors and showing potential for high-density embedded FeRAM.

Summary: This study investigated the contribution of LINC01296 in the modulation of oral cancer stem cells (CSCs). The results showed that suppression of LINC01296 can reduce the aggressiveness, stemness features, and self-renewal abilities of oral CSCs. Furthermore, it was demonstrated that LINC01296 may enhance cancer stemness features through the suppression of miR-143. Therefore, silencing of LINC01296 could be a promising direction for oral cancer therapy.

Summary: This study aimed to investigate the role of tumor-suppressive circRNA circAAGAB in breast cancer. The findings suggest that circAAGAB, which is stabilized by interacting with RNA binding protein FUS, acts as a tumor suppressor by up-regulating the expression of KIAA1522, NKX3-1, and JADE3 through miR-378 h sponge. The results showed that circAAGAB reduced cell colony formation, cell migration, and signaling through the p38 MAPK pathway, as well as increased radiosensitivity.

Summary: Obstructive sleep apnea (OSA) is a common sleep-related breathing disorder, and polysomnography (PSG) is the standard diagnostic test. However, PSG is time-consuming and may result in long waiting periods. To address this, portable and wearable tools have been developed as low-cost alternatives to PSG for OSA classification. This paper presents a deep neural network (DNN)-based model that uses peripheral oxygen saturation (SpO2) signals to classify OSA severity. The model achieves high accuracy and sensitivity, with potential for clinical use.

Summary: This study found that alpha-mangostin can inhibit the development of oral submucous fibrosis and also reduce the expression of long non-coding RNA LincROR. The results suggest that alpha-mangostin has anti-fibrosis effects, which may be achieved through the downregulation of LincROR.
