“…It has been reported that ES application has a protective effect on plants under oxida-tive stress [45], which is similar to the effect of brassinosteriods (BRs), plant-specific steroid hormones, structurally similar to ES, on plant abiotic stress responses [23]. Ex- Phenylpropanoids and flavonoids are not only required for normal plant growth and development but they also play an important role in protecting plants against various stresses, including pathogen attacks [48] [49].…”

Mammalian sex hormones are spread in the environment from natural and anthropogenic sources. In the present study, the effect of estradiol on Arabidopsis thaliana growth primary metabolism, phenylpropanoid and flavonoid pathways and pathogen resistance were investigated. Treatments of Arabidopsis plants with 10 and 100 nM 17β-estradiol resulted in enhanced root growth and shoot biomass. In addition, treated plants had an increased rate of photosynthesis with a concomitant increase in carbohydrate and protein accumulation. Plants exposed to higher concentrations of 17β-estradiol (10 μM) had significantly lower root growth, biomass, photosynthesis rate, primary metabolite and phenylpropanoid and flavonoid contents indicating a toxic effect of estradiol. Treatments with increasing estradiol concentrations (10 nM, 100 nM and 10 μM) resulted in the downregulation of phenylpropanoid-flavonoid pathway genes (PAL1, PAL4, CHI and ANS) and subsequent decreased accumulation of phenolics, flavonoids and anthocyanins. Estradiol-treated plants were inoculated with Pseudomonas syringae pv. Tomato DC3000 and basal resistance was determined. Estradiol treatments rendered plants susceptible to the pathogen, thus compromising the plant defense mechanisms. These results indicate that at low concentrations, estradiol functions as a biostimulant of growth, yield and primary metabolism of Arabidopsis. However, estradiol functions as a potential transcriptional regulator of the phenylpropanoid pathway genes in Arabidopsis, having a negative effect on the phenylpropanoid and flavonoid biosynthetic pathways.

“…Despite the fact that MSHs act as endocrine disruptors in aquatic animals, a number of studies have demonstrated their beneficial effects on plants coping with abiotic stresses [3]- [9]. Progesterone, 17β-estradiol and androsterone applications mitigated the effects of salinity stress by enhancing germination rate, and root and shoot length in maize [6] and wheat seedlings [7]. The protective effect of MSHs has also been reported in the case of chilling and heavy metal stresses [8] [9].…”

Animal steroidal hormones, including estrogens, are being introduced into the agricultural soil and water supply from increased pharmaceutical and farm waste. Considering the current levels of xenoestrogen contamination of plant environments in view of the climate change induced drought conditions, this study was designed to understand the effect of estradiol (ES) application on Arabidopsis drought stress responses. Estradiol treatment (10 nM, 100 nM) of plants subjected to drought stress conditions by withholding water for 7 days resulted in increased tolerance to drought stress reflected in the significantly higher plant survival rates of 74% and 78%, respectively compared to control plants' survival rates of 36% (no treatment) and 40% (mock treatment). Estradiol application significantly increased the content of glutathione, proline and H 2 O 2 and significantly enhanced the transcription of the stress responsive genes GSTU3, GER5, HSP101, and HSP70b. A high concentration of ES (10 µM) did not protect plants against drought stress and proved to be toxic. These results provide new insight into the effect of ES on drought-stress responses in Arabidopsis with possible practical agricultural applications regarding the effect of environmental estrogens on crop plants.

“…Another androgen (androsterone) stimulated resistance to cold in maize plants, among others, by decreasing the membrane damage (also measured by electrolyte leakage) (Erdal 2012a). Improvement of the resistance to stress (for example, drought, salinity) through the application of AN and other androgens has also been reported by Janeczko and others (2012) and Erdal (2012b).…”

development of wheat. The AN-induced changes in redox homeostasis seemed to be important for processes of acclimation to low temperature and generative induction. AN influenced hormonal balance in wheat and stimulated accumulation among other gibberellins and cytokinins. For example, in aerial part of plants, the content of GA 3 was increased by AN in 12 days of cold by about 30%, whereas the content of cis-zeatin was increased by 65%. AN was absorbed into plant membranes (Langmuir bath studies). The membrane absorption of AN increased the distance between lipid molecules and this may be an important step in the AN-induced enhancement of frost resistance. AN interaction with lipid membranes showed similarity to the interactions of some known regulators stimulating flowering in plants, and thus it may also underlie the acceleration Abstract Understanding of the physiological role of mammalian hormone-androstenedione (AN)-in plants is scant and the mechanisms of its action at a cellular level are practically unknown. The aim of this study was to investigate the physicochemical and biochemical background of AN activity in winter wheat exposed to low temperature. Cold periods are important in the lifecycle of this species as they induce frost resistance and further generative development. Wheat seedlings (control and AN-supplemented) were acclimated 2 weeks in cold and then exposed to frost (−12 °C). AN supplementation reduced frost damages by 30%. Moreover, AN also accelerated generative Electronic supplementary material The online version of this article
