Mammalian sex hormones in plants.
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 pl...
متن کاملGrowth hormones. 1. Polymorphism (minireview).
Pituitary growth hormone (GH) is not a single molecular species, but a whole set of similar molecules, the individual specific characteristics of which constitute the polymorphism of this hormone. The present paper deals mainly with various forms of human GH, called "variants", and touches on this polymorphism in other species as well. The 22 K variant (MW = 22,000 daltons) is the predominant f...
متن کاملGenetic Engineering and Biotechnology of Growth Hormones
In its modern conception, biotechnology is the use of genetic engineering techniques to manipulate microorganisms, plants, and animals in order to produce commercial products and processes that benefit man. These techniques, which are the backbone of the biotechnological revolution that began in the mid 1970s, have permitted the isolation and manipulation of specific genes and the development o...
متن کاملBushbaby growth hormone is much more similar to nonprimate growth hormones than to rhesus monkey and human growth hormones.
Unlike other mammals, Old World primates have five growth hormone-like genes that are highly divergent at the amino acid level from the single growth hormone genes found in nonprimates. Additionally, there is a change in the interaction of growth hormone with its receptor in humans such that human growth hormone functions in nonprimates, whereas nonprimate growth hormone is ineffective in human...
متن کاملPost-Translational Modifications in Secreted Peptide Hormones in Plants
More than a dozen secreted peptides are now recognized as important hormones that coordinate and specify cellular functions in plants. Recent evidence has shown that secreted peptide hormones often undergo post-translational modification and proteolytic processing, which are critical for their function. Such 'small post-translationally modified peptide hormones' constitute one of the largest gr...
