Summary: The study investigated the temporal expression of EBF-binding proteins and other OBPs in aphids, revealing that winged aphids are more sensitive to EBF. OBP7 showed significantly higher antennal expression in winged aphids, while OBP3 did not differ significantly in most time points, providing important insights for selecting morphs and sampling times.

Summary: Global warming affects pest populations and their distribution, leading to changes in interspecific interactions. Increased temperature results in increased competition and affects the distribution of aphids. Chemical content in plant tissues and environmental factors may explain the distribution of aphids across different plant parts.

Summary: Plants can perceive and respond to volatile organic compounds released by neighboring plants to protect themselves from environmental threats. An increase in cytosolic calcium ion concentration plays a crucial role in this perception and response process in Arabidopsis leaves.

Summary: Understanding the chemical recognition of Ophraella communa for Ambrosia artemisiifolia can enhance its biological control effect. In this study, OcomOBP7 was cloned and the tissue expression and binding ability were analyzed, revealing the involvement of OcomOBP7 in the chemical recognition of A. artemisiifolia by O. communa. These findings lay a theoretical foundation for the development of attractants for O. communa and contribute to the better biological control of A. artemisiifolia.

Summary: Green leaf volatiles (GLVs) are six-carbon volatile aldehydes, alcohols, and esters formed from polyunsaturated fatty acids, involved in plant defense. GLVs are quickly activated in plant tissues by mechanical damage. Monilophytes and lycophytes show substantial GLV-burst ability, while bryophytes have limited capability.

Summary: Green leaf volatiles (GLVs) are volatile compounds ubiquitous in vascular plants that are rapidly synthesized in response to stress and play an important role as mediators between plants and interacting organisms. GLVs can directly deter or attract organisms that interact with plants, while also enhancing the defense mechanisms of other plants through a process called priming. Although the individual effects of GLVs may be small, the cumulative effects of their multiple functions can substantially benefit plants.

Summary: This study investigates the effects of plant developmental stages on the production of aldehyde GLV and finds that the capacity to produce these compounds strongly depends on the growth stage of the plant. Significant differences in quantity and quality of these compounds are found not only in leaves from different developmental stages but also within different areas of the same leaf.

Summary: The study found that tomato plants predominantly accumulated GLV-glycosides after exposure to green leaf alcohols, and validated the mechanisms of Arabidopsis mutants in processing exogenous GLVs. These findings provide important insights into plant communication within their ecosystem and can help develop strategies for crop protection and maintaining a balanced ecosystem.

Summary: This study reveals the olfactory mechanism of Eastern honeybees' pollenating loquat flowers in cold early winter. It is found that the odorant-binding protein, OBP2, has a strong binding affinity with three loquat volatiles, 4-Methoxybenzaldehyde, (E)-Ethyl cinnamate, and Methyl cinnamate at low temperatures. Site-directed mutagenesis experiments indicate that Met55 and Lys51 play important roles in the interaction between OBP2 and Methyl cinnamate. These findings contribute to the understanding of temperature-adaptive ecological mechanism of insect pollination.

Summary: This study investigates the effects of volatiles released by bean plants upon infestation by aphids on the population dynamics and fitness of another aphid species, as well as on wheat phloem sap metabolites. The results suggest that these volatiles can benefit the aphids by increasing their survival rate, leading to larger colonies.

Summary: In this study, the researchers produced the RpedOBP4 protein from Riptortus pedestris using a recombinant expression system and investigated its binding properties with soybean volatiles. The results revealed the key amino acid residues involved in the binding process. These findings not only contribute to a better understanding of the olfactory mechanism of R. pedestris during soybean feeding, but also provide potential targets for developing environmentally friendly and efficient behavior inhibitors.
