TLDR
Five aspects of allelochemicals are discussed from an ecophysiological perspective: biosynthesis, modes of release, mode of action, detoxification and prevention of autotoxicity, and joint action of alleLochemicals.Abstract:
Allelochemicals play an important role in explaining plant growth inhibition in interspecies interactions and in structuring the plant community. Five aspects of allelochemicals are discussed from an ecophysiological perspective: (i) biosynthesis, (ii) mode of release, (iii) mode of action, (iv) detoxification and prevention of autotoxicity, and (v) joint action of allelochemicals. A discussion on identifying a compound as an allelochemical is also presented.read more

Regulation and function of root exudates.
TL;DR: This review focuses on compiling the information available on the regulation and mechanisms of root exudation processes, and provides some ideas related to the evolutionary role ofRoot exudates in shaping soil microbial communities.
Journal ArticleDOI
Biochemical and physiological mechanisms mediated by allelochemicals
TL;DR: Progress has been made in understanding the biochemical and molecular changes that are induced by alleLochemicals in susceptible plant species, and the complex mechanisms that are used by allelochemical-resistant plants to defend against this toxic insult.

Phenolic acids act as signaling molecules in plant-microbe symbioses
TL;DR: The well-known roles attributed to phenolic compounds as nod gene inducers of legume-rhizobia symbioses, their roles in induction of the GmGin1 gene in fungus for establishment of arbuscular mycorrhizal symbiosis, and their roles as defense molecules operating against soil borne pathogens that could have great implications for rhizospheric microbial ecology are described.

Types, amounts, and possible functions of compounds released into the rhizosphere by soil-grown plants
TL;DR: The rhizosphere is defined here as that volume of soil affected by the presence of the roots of growing plants as discussed by the authors, and it is defined as the area of the soil that can be changed by the growth of a plant.

In Posidonia oceanica cadmium induces changes in DNA methylation and chromatin patterning
TL;DR: The data demonstrate that Cd perturbs the DNA methylation status through the involvement of a specific methyltransferase, linked to nuclear chromatin reconfiguration likely to establish a new balance of expressed/repressed chromatin.

Plant Physiological Ecology
TL;DR: This textbook is notable in emphasizing that the mechanisms underlying plant physiological ecology can be found at the levels of biochemistry, biophysics, molecular biology and whole-plant physiology, well-suited to assess the costs, benefits and consequences of modifying plants for human needs, and to evaluate the role of plants in ecosystems.

Hydroxamic acids (4-hydroxy-1,4-benzoxazin-3-ones), defence chemicals in the Gramineae
TL;DR: Hydroxamic acids of the type 4-hydroxy-1,4-benzoxazin-3-ones constitute one of the most extensively studied secondary metabolites in relation to host plant resistance to pests and diseases.
