Summary: Water availability has a significant impact on plant-herbivore interactions. This review summarizes recent research on the effects of water availability on plant antiherbivore defense and the physiological processes involved. Water deficit tends to enhance certain defense traits but negatively affects others, and the impact of water availability on species interactions and plant evolution is discussed. However, there is a lack of study on the interactive impact of additional abiotic stressors on water-plant-herbivore interactions.

Summary: This study demonstrates the significance of CO2 perception in western corn rootworm larvae and how it affects their interaction with host plants, particularly in long-distance host location. The ability of larvae to perceive root-emitted CO2 plays a crucial role in their preferred orientation towards well-fertilized plants.

Summary: Domestication has a greater impact on the abundances and diversity of maize root volatiles than northward spread and modern breeding. The preference of the herbivore for maize roots is correlated with volatile diversity and herbivore resistance. Changes in abundances of individual volatiles are evident at the level of volatile groups, and maize domestication has the greatest effects.

Summary: Climate change has complex effects on belowground tritrophic interactions within agricultural systems. While individual abiotic factors influence plant growth and insect performance, their combined effects under predicted climate scenarios often counterbalance each other. However, drought has a significant negative impact on leaf wilting.

Summary: Herbivore-induced plant volatiles (HIPVs) are released by plants in response to damage or disturbance by phytophagous insects. These HIPVs serve as signals and can be used by predators and parasitoids to locate herbivores at different spatial scales. Understanding and closing the loopholes regarding the role of HIPVs can contribute to sustainable pest management in agriculture.

Summary: Dehydration tolerance in plants is crucial for drought survival, and it is influenced by factors such as soil water content, vapour pressure deficit, and plant-plant interactions. This study compared the dehydration dynamics, mortality, and recovery of two perennial grass species under different drought conditions, and found that plant-plant interactions can improve dehydration tolerance and drought resistance. The study also revealed that dehydration of leaf meristems leads to plant mortality, and acclimation to drought can increase dehydration tolerance.

Summary: Extensive transcriptomic analyses have revealed distinct differences in the gene expression profiles of maize plants upon shoot and root attack, both locally and distantly from the affected tissue. This study provides detailed insights into the specificity of plant defense responses and offers a molecular resource for further genetic studies on maize resistance to herbivores. It also paves the way for novel strategies to enhance maize resistance to pests.

Summary: Climate change affects plant-microbiome interactions and ecological functions in various scales. Short-term plant adaptation to climate change relies on the plant microbiome, while long-term adaptation is equally driven by eco-evolutionary interactions between the plant microbiome and its host. Understanding these dynamics can inform predictions of climate change impacts on primary productivity and help in developing management strategies for plant systems.

Summary: Global climate change has led to abiotic stresses that affect plant growth and productivity. Plants have developed various endogenous strategies, such as plant hormone biosynthesis, to withstand these stresses. Abiotic stresses disrupt normal transportation systems in plants, leading to oxidative stress. Plant defense systems, including enzymatic and non-enzymatic mechanisms, help protect plants from oxidative stress.

Summary: Microbes associated with insects play a significant role in the interactions between herbivorous insects, pollinators, and their host plants. These interactions can have implications for the health and immunity of pollinators, highlighting the importance of plant quality, gut microbiomes, and multitrophic interactions between herbivores and pollinators. Additionally, other herbivore-associated factors, such as agricultural inputs aimed at pest control, can also impact pollinator microbiomes.

Summary: Light serves as a crucial external cue for plants to coordinate growth and performance with changing environmental conditions. Recent studies have shown that the red/far-red light-absorbing phytochrome photoreceptors, especially phyB, play a key role in plant adaptation responses, particularly in coping with stress.

Summary: The identity and density of herbivores interact to determine plant responses and herbivore fitness. Low densities exhibit species-specific effects, while high densities converge. Considering herbivore identity and density is important for understanding plant-mediated interactions between herbivores.

Summary: Herbivore population dynamics are affected by plant-mediated interactions. Leaf herbivory by one herbivore species can affect the performance of conspecific pupae in the soil. This study shows that the aboveground herbivory triggers changes in root defense signaling and volatile production, which can alter the pupal development time.

Summary: Climate change can influence plant-herbivore interactions and their associated ecosystem functions. An experimental study on invasive Ambrosia artemisiifolia showed that warming and herbivory by biocontrol beetles can lead to changes in the genetic composition and metabolomic profiles of plants, resulting in increased offspring biomass and resistance to herbivory. However, climate warming could reduce biocontrol efficiency and promote Ambrosia invasion, with potential economic and health consequences.

Summary: Herbivore-induced plant volatiles play a crucial role in regulating defenses in undamaged neighboring plants. Understanding the mechanisms of plant volatile uptake, perception, and translation into defense signaling pathways is essential. Various molecular processes, such as membrane-associated and intracellular receptors, as well as mitogen-activated protein kinases (MAPKs), WRKY transcription factors, and jasmonates, are involved in translating volatiles into defense priming and induction. The diverse molecular processes in volatile signaling result in spatiotemporal and ontogenetic variation in plant responsiveness to volatiles, which has significant implications for plant-environment interactions.

Summary: Benzoxazinoids are specialized metabolites that play multiple roles in plant physiology and interactions with the environment, regulating plant nutrition, growth, and defense. Plants can modulate benzoxazinoid production in response to environmental factors, and these compounds act as strong selective forces on different trophic levels by shaping plant interactions with other organisms, impacting (agro)ecosystem functioning and diversity.

Summary: This study investigates the metabolization of benzoxazinoids (BXs) in silages of two maize genotypes during aerobic deterioration. It finds that the concentration of BXs in silage decreases over time in the wild type maize, while the concentration increases in mutant maize. Aerobic stability is influenced by BXs, and the nutrient composition is not affected. Further research is needed under different conditions.

Summary: Plants shape terrestrial ecosystems through physical and chemical interactions, particularly through their volatile organic compounds, which influence the behavior and performance of other organisms. This review discusses the production, release, and regulation of vegetative plant volatiles, as well as their effects on various organisms. Concepts such as multifunctionality of specialized metabolites, chemical communication displays, and volatile physiochemistry can help explain and predict the evolution and expression patterns of vegetative plant volatiles. The multifaceted roles of vegetative plant volatiles provide opportunities to understand ecosystem dynamics and utilize them for sustainable agriculture.
