Biostimulants, which may be derived from a wide range of natural or synthetic processes, are now widely used in agriculture and yet the mode of action of these materials is not well understood. On the basis of available literature, and based upon the diversity of biostimulant responses highlighted in this focus issue, we hypothesize that biostimulants function by directly interacting with plant signaling cascades or act through stimulation of endophytic and non-endophytic bacteria, yeast and…

Use of microbial biostimulants in organic farming

Progress of Plant Biostimulants

The plant biostimulants are diverse substances or microorganisms which include humic acid, chitin and its derivatives, seaweed extracts, etc. applied to enhance plant growth, development, tolerance

Biostimulants in Plant Science: A Global Perspective

This review suggests that the focus of biostimulant research and validation should be upon proof of efficacy and safety and the determination of a broad mechanism of action, without a requirement for a specific mode of action.

Phytobiome Engineering and Its Impact on Next-Generation Agriculture

The role of quorum sensing and signaling and its application in the eco-friendly method of farming that is sustainable agriculture is focused on.

The role of biostimulants and bioeffectors as alleviators of abiotic stress in crop plants

An extensive review of the literature shows a clear role for a diverse number of biostimulants that have protective effects against abiotic stress but also reveals the urgent need to address the underlying mechanisms responsible for these effects.



Agricultural uses of plant biostimulants

There is growing scientific evidence supporting the use of biostimulants as agricultural inputs on diverse plant species, such as increased root growth, enhanced nutrient uptake, and stress tolerance.

Biological mode of action of a nitrophenolates-based biostimulant: case study

Information is provided on the mode of action of a nitrophenolates-based biostimulant, Atonik, in model species and economically important crops grown under both field and controlled conditions in a growth chamber.

Seaweed Extracts as Biostimulants of Plant Growth and Development

A comprehensive review of the effect of various seaweed species and seaweed products on plant growth and development with an emphasis on the use of this renewable bioresource in sustainable agricultural systems is provided.

Biostimulant action of a plant-derived protein hydrolysate produced through enzymatic hydrolysis

The application of plant-derived protein hydrolysate containing amino acids and small peptides elicited a hormone-like activity, enhanced nitrogen uptake and consequently crop performances.

Foliar application of microbial and plant based biostimulants increases growth and potassium uptake in almond (Prunus dulcis [Mill.] D. A. Webb)

There was a substantial positive effect of both biostimulant treatments on total shoot leaf area, and significant increases in shoot length and biomass under adequate soil potassium supply with apositive effect of Bio-1 only under low K supply.

Capsicum chinensis L. growth and nutraceutical properties are enhanced by biostimulants in a long-term period: chemical and metabolomic approaches

Two biostimulants, one derived from alfalfa plants (AH) and the other obtained from red grape (RG), were chemically characterized using enzyme linked immuno-sorbent assays, Fourier transform infrared (FT-IR) and Raman spectroscopies and suggested that AH and RG promoted plant growth and the production of secondary metabolites, such as phenols.

Carbohydrates in plant immunity and plant protection: roles and potential application as foliar sprays

The state of the art about perception of “PAMP, MAMP, and DAMP (Pathogen-, Microbe, Damage-Associated Molecular Patterns) type” oligosaccharides is presented and examples of induced defense events are provided.

The importance of the microbiome of the plant holobiont.

It is suggested that the plant can modulate its microbiota to dynamically adjust to its environment and to better understand the level of plant dependence on the microbiotic components, the core microbiota need to be determined at different hierarchical scales of ecology while pan-microbiome analyses would improve characterization of the functions displayed.

Foliar treatments with Gaultheria procumbens essential oil induce defense responses and resistance against a fungal pathogen in Arabidopsis

Results show that the G. procumbens essential oil is a natural source of MeSA which can be formulated to develop new biocontrol products and is similar to the commercial product BION®.

Plant growth in Arabidopsis is assisted by compost soil-derived microbial communities

Plants in natural and agricultural environments are continuously exposed to a plethora of diverse microorganisms resulting in microbial colonization of roots and the rhizosphere. This process is
