“…Recently, attempts were made to use JA on algae to enhance metabolite production. JA enhanced heavy metal toxicity leading to a decrease in cell number, chlorophylls, and carotenoids, as well as antioxidant enzyme activity in C. vulgaris (Piotrowska-Niczyporuk et al, 2012). Moreover, Czerpak et al (2006) discussed the influence of exogenous JA upon the growth and changes in some metabolite levels in the cells of green alga C. vulgaris.…”

“…The involvement of plant hormones such as IAA, CK, and ET to alleviate HMs-induced toxicity is well reported [47][48][49]. Some recent studies suggest that NO acts in concert with signaling pathways of phytohormones to induce tolerance against excess elements [50,51].…”

Phytohormones - Signaling Mechanisms and Crosstalk in Plant Development and Stress Responses

View full text Add to dashboard Cite

Plants, being sessile, are concurrently exposed to various biotic and abiotic stresses. The perception of stress signals in plants involves a wide spectrum of signal transduction pathways that interact to induce tolerance against adverse environmental conditions. This functional overlapping among various stress signaling cascades also leads to the expression of genes that regulate biosynthesis or action of other hormones. Phytohormonal signals, activated by both developmental and environmental responses, play a crucial role to develop stress tolerance in plants. Nitric oxide (NO) is one of the major players in plant signaling networks. Emerging evidence supports that NO interplays with signaling pathways of auxins, gibberellins, abscisic acid, ethylene, jasmonic acid, brassinosteroids, and other plant hormones to control metabolism, growth, and development in plants. This chapter focuses on the current state of knowledge of cross talk between signaling pathways of NO and phytohormones in plants exposed to various abiotic stresses.

“…The axenic cultures of C. vulgaris were grown in modified Knop's medium under the conditions of 50 lmol m -2 s -1 light intensity and 16:8-h light/dark cycle at 25°C (Bajguz 2010(Bajguz , 2011Piotrowska-Niczyporuk et al 2012). Synchronization of the culture was controlled by studying cell division and the diagrams of cell size distribution.…”

“…C. vulgaris is commonly found in freshwater and seawater and has a short growth cycle, which makes it ideal for biochemical studies and it can be used to directly observe phytohormone response at the cellular level, because observation of the signalling molecule and biochemical response takes place within the same cell under controlled conditions (Piotrowska-Niczyporuk et al 2012).…”

The effect of exogenously applied natural [indole-3-acetic acid (IAA), phenylacetic acid (PAA), indole-3-butyric acid (IBA)] and synthetic [1-naphthaleneacetic acid (NAA)] auxins on the growth and metabolism of green microalga Chlorella vulgaris was examined. Exogenous auxins acted in a concentration-dependent manner on algal growth. Phytohormones at concentration of 100 lM inhibited algal growth expressed as the number of cells. IAA and IBA displayed the highest biological activity at 0.1 lM, whereas PAA and NAA were characterized by the greatest stimulatory effect on the number of cells at 1 lM. Treatment with IAA and IBA at 0.1 lM or NAA and PAA at 1 lM increased the concentration of photosynthetic pigments, monosaccharides and soluble proteins in C. vulgaris. Moreover, all auxins stimulated enzymatic (ascorbate peroxidase, catalase, superoxide dismutase) and non-enzymatic antioxidant (ascorbate, glutathione) systems in C. vulgaris, and therefore, suppressed lipid peroxidation and hydrogen peroxide accumulation. The data supports the hypothesis that auxins play a central role in the regulation of C. vulgaris growth and metabolism and the components of cellular redox systems that are thought to have a prominent role in the regulation of auxindependent processes.
