Summary: This study elucidated the biosynthetic order of PLVs and revealed differences in volatile metabolism between GLVs and PLVs, leading to the establishment of a more robust PLV pathway. Additionally, the study demonstrated that PLVs can enhance plant resistance to pathogens through induction of specific oxylipins.

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 explores the use of gold nanoparticles on flexible cotton fabric as sensitive substrates for acetone and ethanol, utilizing impedance measurements. The nanoparticles were synthesized using green methods and then deposited on cotton fabric. The study found that the functionalization of the nanoparticles affects the electrical interconnection and electron transport, leading to different sensing properties for acetone and ethanol. The findings have potential implications for the development of VOC sensors in personal protective equipment and wearable telemedicine devices, as well as low-cost detectors for disease diagnosis based on breath volatiles.

Summary: The study found that volatile organic compounds emitted by six potential companion plant species can affect the reproduction of Myzus persicae feeding on pepper plants, with VOCs from Ocimum basilicum and Tagetes patula reducing the fecundity of aphids. Therefore, the species and phenology of companion plants can influence the impact on pests.

Summary: This study conducted a genome-wide association analysis to investigate the biosynthetic pathways and regulatory networks of metabolites and volatiles in rice. The results revealed close relationships between metabolites and volatiles in rice and its development, biotic and abiotic stresses. Some important compounds were found to be strongly associated with certain phenotypes of rice, providing valuable insights into the understanding of biosynthetic pathways and regulatory networks.

Summary: This study investigates the role of (Z)-3-hexeny-1-yl acetate (Z-3-HAC) in alleviating wheat drought stress. The results show that Z-3-HAC improves the growth and biomass accumulation of wheat seedlings under drought stress by enhancing physiological mechanisms such as water content, photosynthetic rate, and antioxidant activity. The study highlights the potential application of Z-3-HAC for improving wheat drought resistance.
