The occurrence of mammalian sex hormones and their physiological role in plants is reviewed. These hormones, such as 17beta-estradiol, androsterone, testosterone or progesterone, were present in 60-80% of the plant species investigated. Enzymes responsible for their biosynthesis and conversion were also found in plants. Treatment of the plants with sex hormones or their precursors influenced plant development: cell divisions, root and shoot growth, embryo growth, flowering, pollen tube growth…

Plants are Capable of Synthesizing Animal Steroid Hormones

This review summarizes the current state of knowledge on the occurrence of animal steroid hormones in the plant kingdom, particularly focusing on progesterone, testosterone, androstadienedione (boldione), androstenedione, and estrogens.

Estrogens and Androgens in Plants: The Last 20 Years of Studies

The presence of testosterone, 17β-estradiol, and other androgens/estrogens in plants (particularly those that can be measured using more advanced techniques) is described and the physiological activity of androgens and estrogens, especially in plants’ stress response, are discussed.

MAMMALIAN SEX HORMONES AFFECT REGENERATION CAPACITY AND ENZYMES ACTIVITY OF TRITICALE L . IN VITRO CULTURE

It was clear that mature embryo interacted with the mammalian sex hormones, and estron group gave the best result in terms of explant percentage forming shoots, followed by of progesterone group in mammalian sex hormone applications.

The Effect of Mammalian Sex Hormones on Polymorphism and Genomic Instability in the Common Bean (Phaseolus vulgaris L.)

The results indicate that 17 β-estradiol, estrogen, progesterone, and testosterone in bean plants affect genomic instability and cause epigenetic modifications, which is an important control mechanism in gene expression.

Into the world of steroids

Endocrine disrupting compounds such as the estrogen agonist bisphenol A (BPA) are widespread in the environment, posing a potential hormonal risk to animals and plants.

MAMMALIAN SEX HORMONES AFFECT REGENERATION CAPACITY AND ENZYMES ACTIVITY OF TRITICALE (X TRITICOSECALE WITTMACK) IN VITRO CULTURE

This study is the first report that determines the effects of 17β-estradiol, estrone, progesterone and androsterone among the mammalian sex hormones on in vitro regeneration of Triticale mature

Exogenous steroid hormones stimulate full development of autonomous endosperm in Arabidopsis thaliana.

It is shown that Arabidopsis thaliana has a high potency to fertilization-independent development, and the methods of improving the quality of the endosperm obtained using plant and mammalian steroid hormones are demonstrated.

Biosynthesis and Industrial Production of Androsteroids

The entire plant steroid biosynthesis is not fully elucidated, so knowing this pathway could provide new processes for the industrial biotechnological production of steroid hormones in plants.

ALTERATION OF GROWTH AND FLOWERING OF Cucumis sativus L. BY APPLICATION OF SEX STEROIDS in vitro

Application of the tested sex steroids in vitro altered flower morphology, and pollen viability in the anthers of male flowers developed on plants cultured on the media with steroids was decreased, compare to control, suggesting their effect on pollen development.

Stimulation of generative development in partly vernalized winter wheat by animal sex hormones

Investigated steroids stimulated the generative development of winter wheat by an increasing in the percentage of heading plants and accelerating the heading and the strongest effect was observed when plants were treated with steroids during the suboptimal, 21 and 28 day, vernalization.

Immunoreactive detection of four mammalian steroids in plants

Radioimmunoassay was used to detect the presence of androstenone (boar taint), androgen, estrogen, and progesterone, which were widespread in plant species and the function of these steroids in plants is not known.

Steroid Hormones Stimulate Germination and Tube Growth of in Vitro Matured Tobacco Pollen

Application of the mammalian steroid sex hormones resulted in a stimulation of pollen germination and tube elongation and the presence of both steroids and flavonols in the germination medium strongly enhanced the growth of tobacco male gametophytes.

This work provides first evidences on the existence of estrogen binding proteins structurally related to the mammalian ER alpha subtype in a higher plant system using 17beta-estradiol macromolecular derivatives as ligands.
