Key ResultIn various algal taxa, essentially all known phytohormones were detected in concentrations comparable with their content in higher plants. The occurrence of diverse free and conjugated hormone forms substantiates the functioning of the complex system of metabolism and activity regulation of these compounds. In most cases, the spectrum of biological activities of algal hormones corresponds to the functions of higher plant hormones. Some physiological and biochemical processes in algal cells and…

Biosynthesis of phytohormones in algae

All known phytohormones were identified in various algal taxa, and the range of their physiological activities was confirmed.

Chemically-mediated interactions in microalgae

There is some evidence for microalgae affecting bacterialQuorum sensing, and for quorum sensing in cyanobacteria.

Regulation of algal and cyanobacterial auxin production, physiology, and application in agriculture: an overview

Algal bioproducts are of growing interest to agriculture because of their biodegradable nature, ability to restore soil fertility, and capacity for plant growth regulation, nitrogen fixation, and carbon sequestration, but knowledge of their precise mechanisms of action is still rudimentary.

Chemistry on Plant Growth Regulators: An overview

A natural substance that acts to control plant activities are Plant growth regulators and often called phytohormones to regulate growth, development and responses to stimuli. Which includes hormones

This chapter summarizes the studies of brassinosteroids on algal cultures in the last three decades, which suggest that the operation of the early and late C6-oxidation pathways, lead to brassinolide existence in algae.

The Biomass of Algae and Algal Extracts in Agricultural Production

Fertilizers and plant growth regulators (PGRs) based on seaweeds are commonly known, having been produced and utilized for dozens of years. Algae are rich in carbohydrates, proteins, minerals and

Phytohormone up-regulates the biochemical constituent, exopolysaccharide and nitrogen metabolism in paddy-field cyanobacteria exposed to chromium stress

Overall result of the present study signifies affirmative role of the phytohormone in minimizing the toxic effects induced by chromium by stimulating the growth of cyanobacteria thereby enhancing its ability as bio-fertilizer that improved fertility and productivity of soil even in metal contaminated condition.



The chemical characteristic and distribution of brassinosteroids in plants.

Gibberellins as endogenous growth regulators in green and brown algae

It is concluded that gibberellins are normally involved in regulating growth in green and brown algae.


Whether exogenous auxin concentrations produce growth responses in non-vascular plants, such as the brown algae, comparable to those obtained in vascular plants is determined.

Volume 8 summarizes the chemistry of various biofunctional molecules and bioactive natural products of both terrestrial and marine origin and stresses the importance of chirality in natural products chemistry.

Gibberellin-like Substances in Plants

This communication reports the first evidence for the presence of gibberellin-like substances in the latter two groups of gymnosperms and ferns.

The occurrence of lunularic and abscisic acids in plants

Oligosaccharins, brassinolides, and jasmonates: nontraditional regulators of plant growth, development, and gene expression.

Each of the nontraditional plant hormones reviewed in this article, oligosaccharins, brassinolides, and JA, can exert major effects on plant growth and development. However, in many cases, the

Effect of brassinosteroids on growth and proton extrusion in the alga Chlorella vulgaris Beijerinck (Chlorophyceae)

The growth in Chlorella vulgaris was associated with an increase in the capability of algal cells to acidify the medium, where brassinolide is biologically more active than 24-epibrassinolide.

Toxicity of 40 herbicides to the green alga Chlorella vulgaris.

The effects on the green alga Chlorella vulgaris of 40 herbicides in 19 different chemical structure classes and with 11 dissimilar modes of action were studied through 96-h acute toxicity tests.

Comparison of cytokinin- and auxin-like activity in some commercially used seaweed extracts

Six commercially used seaweed extracts were tested for cytokinin- and auxin-like activity using the soybean callus bioassays and the mung bean rooting bioassay respectively and improved rooting of mung beans was found.
