[学术文献 ] Flowering Ocimum gratissimum intercropped in tea plantations attracts and reduces Apolygus lucorum populations 进入全文
Pest Management Science 期刊
BACKGROUND Apolygus lucorum is one of the most important piercing-sucking insect pests of the tea plant In this study, we assessed the attractiveness of basil plants to A. lucorum and the effectiveness of Ocimum gratissimum L. in the control of A. lucorum. The control efficiency of main volatile chemicals emitted from O. gratissimum flowers was also evaluated. RESULTS Among seven basil varieties, O. gratissimum was more attractive to A. lucorum adults and was selected as a trap plant to assess its attractiveness to A. lucorum and effects on natural enemies in tea plantations. The population density of A. lucorum on trap strips of O. gratissimum in tea plantations was significantly higher than that on tea at 10–20 m away from the trap strips. Intercropping O. gratissimum with tea plants, at high-density significantly reduced A. lucorum population levels. Eucalyptol, limonene, β-ocimene, and linalool were the four dominant components in the O. gratissimum flower volatiles, and their emissions showed a gradual upward trend over the sampling period. Olfactometer assays indicated that eucalyptol and dodecane showed attraction to A. lucorum. High numbers of A. lucorum were recorded on limonene, eucalyptol, and myrcene-baited yellow sticky traps in field trials in which 11 dominant volatiles emitted by O. gratissimum flowers were evaluated. CONCLUSION Our research indicated that the aromatic plant O. gratissimum and its volatiles could attract A. lucorum and planting O. gratissimum has the potential as a pest biocontrol method to manipulate A. lucorum populations in tea plantations.

[学术文献 ] Damage-Associated Molecular Patterns and Systemic Signaling 进入全文
Phytopathology 期刊
Cellular damage inflicted by wounding, pathogen infection, and herbivory releases a variety of host-derived metabolites, degraded structural components, and peptides into the extracellular space that act as alarm signals when perceived by adjacent cells. These so-called damage-associated molecular patterns (DAMPs) function through plasma membrane localized pattern recognition receptors to regulate wound and immune responses. In plants, DAMPs act as elicitors themselves, often inducing immune outputs such as calcium influx, reactive oxygen species generation, defense gene expression, and phytohormone signaling. Consequently, DAMP perception results in a priming effect that enhances resistance against subsequent pathogen infections. Alongside their established function in local tissues, recent evidence supports a critical role of DAMP signaling in generation and/or amplification of mobile signals that induce systemic immune priming. Here, we summarize the identity, signaling, and synergy of proposed and established plant DAMPs, with a focus on those with published roles in systemic signaling.

Our Invention "Plant biotic and abiotic stress meter" is a because they are sessile, unlike other living forms, plants are subject to extreme biotic and abiotic stressors. Plants have developed several effective defense mechanisms that depend on a variety of extrinsic elements like the intensity and duration of the shocks as well as a number of internal components including genotypic and phenotypic constitutions and developmental conditions. In order to create stress signal molecules and activate stress-protective mechanisms, stress management makes use of molecular and biochemical level controls, competency, and speed at which a stress signal is recognized and conveyed. Numerous adaptive responses to biotic and abiotic challenges are regulated by the plants' well-coordinated activity at the morphological, physiological, biochemical, and molecular levels. It has been common practice to genetically modify signaling networks in order to increase plant production under stressful environments. Utilizing cutting-edge biotechnology will make it possible to continue farming in a sustainable way. Two reviews and four research papers covering physiological, molecular, and genomic control as well as signaling networks pertaining to plant responses to biotic and abiotic stimuli are included in this special issue.

[学术文献 ] Plant Biology: Evolution of Volatile-Mediated Plant–Plant Interactions 进入全文
Current Biology 期刊
A new study shows that long-term herbivore exclusion modulates volatile-induced herbivore resistance in tall goldenrod, thus providing evidence for herbivory driving the evolution of volatile-mediated plant–plant interactions in nature. When plants are attacked by herbivores, they start releasing distinct sets of volatiles. These volatiles can repel and intoxicate herbivores, attract herbivore natural enemies, and trigger defensive reactions in non-attacked tissues and plants. Thus, plants not only release but also perceive volatiles as warning cues. Although volatile-mediated plant–plant interactions are likely to be common in nature, their adaptive significance is still under debate. A new study by Aino Kalske, Kaori Shiojiri, André Kessler and colleagues, published in this issue of Current Biology, takes an important step in this direction by showing that herbivore exclusion over 12 years does not reduce the overall capacity of volatile-mediated herbivore resistance in tall goldenrod, but instead strengthens volatile-mediated interactions within genetically identical individuals.
