“…The chemical essence of abscisic acid (ABA) is a 15‐carbon sesquiterpenoid compound that is widely distributed in higher plants and has significant effects on the physiological metabolism of algae (Wang et al, 2022). ABA can mitigate the deleterious effects of environmental stress on higher plants and microalgae (Khasin et al, 2018) and generate resistance to adverse conditions, such as drought, cold, disease, and salt stresses (Mahadi et al, 2022; Liu, Chen, et al, 2018).…”

Microalgal energy storage compounds (carbohydrates, lipids, etc.) can serve as renewable feedstocks for biofuels and biobased chemicals. Traditional methods of inducing the accumulation of energy storage compounds in microalgae, such as abiotic stress (high light intensity, high salinity, nutrient limitation, heavy metals, etc.), can affect the growth of microalgae and limit their efficient accumulation of energy storage materials. Plant hormones are a class of small molecular substances that act as chemical messengers to coordinate plant cell activities and regulate the physiological and metabolic activities of microalgae, including promoting microalgal cell proliferation, improving stress resistance, and enhancing photosynthetic activity, thereby increasing algal biomass and lipid, chlorophyll and protein content. This paper reviews the recent research progress on regulation of the accumulation of energy storage compounds in microalgae by adding exogenous plant hormones combined with abiotic stress, discusses the mechanism of plant hormones regarding the accumulation of energy storage compounds in microalgae, and proposes future research needs.

“…Nevertheless, plant hormone metabolism in microalgae is not as well understood as in higher plants. The main challenges are the low concentrations of phytohormones in microalgae cells and the complex analytical detection techniques (Wang et al, 2022). Less information is known about the regulatory role of phytohormones in microalgae.…”

Macrophytes are large aquatic plants belonging to taxonomically diverse groups. They are adapted morphologically, anatomically and physiologically to grow in aquatic habitats of fresh water, brackish water or sea water. This review is based on the rigorous study of literature and papers based on work done on wetlands and macrophytes. Surveys show that macrophytes form an important component in the structure and functioning of an aquatic ecosystem. They play a vital role in the sustenance of life by providing habitat, food, fodder, fiber, green manure, medicines and other useful products. They act as a bioindicator, influence water quality, perform nutrient cycling and reduce shore erosion. The work concluded that knowledge of floral diversity in any aquatic habitat is essential as each and every plant has its role in food chain and they must be documented and conserved before they become extinct without being acknowledged. Researches must be undertaken to scientifically study and extract the important constituents from unknown flora by identifying them with the help of indigenous people so that it can be further flourished for the welfare of mankind. The aim of this paper is to review the diverse roles of macrophytes and to focus on the conservation of aquatic resources and the biodiversity within them, as they not only provide various ecosystem services but are important for the livelihood and ecological balance.

“…Due to among others the formation of excess reactive oxygen species in stress conditions, the accumulation of lipids is accompanied by inhibition of algal cell division 4 . Auxins are plant hormones whose function is related to detoxification of reactive oxygen species 5 . The indole-3-acetic acid auxin has been reported to increase the growth and metabolism regulation in green algae 6 – 8 .…”

Due to their lipid accumulation potential, microalgae are widely studied in terms of their use in the production of biodiesel. The present study was focused on determination of changes in the biomass production, biochemical composition, accumulation and distribution of fatty acids in neutral lipids, glycolipids, phospholipids and biodiesel properties of soil microalga Eustigmatos calaminaris in response to various levels of nitrogen stress and indole-3-acetic acid supplementation. The highest growth rate, the highest lipid content and daily lipid productivity were noted at the nitrogen limitation up to 25% with IAA supplementation. The increase in NL was associated with nutrient stress. An increase in the level of GL and PL were recorded upon the reduction of the nitrogen content (25% N) and the addition of IAA. The gas chromatography/mass spectrometry analysis demonstrated that C16:0, C16:1, and C18:1 were the main fatty acids in E. calaminaris lipids. As shown by the lipidomic analysis, the IAA supplementation in the nitrogen limitation variants enhanced the content of TAGs in C18:1 and monounsaturated fatty acids. The current findings indicated a potential strategy to improve the fatty acid profile in neutral lipids and high potential of E. calaminaris for biodiesel applications.
