A test mixture of five phytohormones [naphthaleneacetic acid (NAA), naphthoxyacetic acid (NOA), indoleacetic acid (IAA), indolebutyric acid (IBA), and indolepropionic acid (IPA)] was investigated. These compounds were cleanly separated with good resolution by capillary zone electrophoresis with a UV diode array detector using 20 mM sodium phosphate buffer (pH 7.25). The lowest detection limit w...

Hormonal heterophylly, the response of tissues in one phylum to hormones that occur naturally in others, is of current general interest not only to the invertebrate endocrinologist but also to the oncologist. The fact that certain mammalian tissues respond metabolically to hormones elaborated in invertebrates and plants was substantiated during the course of a conference, entitled "Conference W...

3.1. Development, growth and differentiation 3.1.1. Development Development is an umbrella term, referring to the sum of all of the changes that an organism goes through in its life cycle – from germination of the seed through growth, maturation, flowering, and senescence. Development is most readily manifest in changes in from of the organism or organ, such as the transition from the vegetativ...

Strigolactones are a class of carotenoid-derived plant hormones, which impact many functions metabolism in response to environmental stress. They also act as exogenous signals perceived by both mycorrhizal fungi and parasitic plants. The peculiar chemical skeleton these molecules their mode action plants inspired possible applications biomedical fields. In this minireview, an overview the most ...

Plants plastically change their morphological and physiological traits in response to environmental changes, which are accompanied by changes in endogenous levels of phytohormones. Although roles of phytohormones in various aspects of plant growth and development were elucidated, their importance in the regulation of biomass allocation was not fully investigated. This study aimed to determine c...

One strategy for sessile plants to adapt to their surrounding environment involves the modulation of their various internal phytohormone signaling and distributions when the plants sense environmental change. There are currently dozens of identified phytohormones in plant cells and they act in concert to regulate plant growth, development, metabolism and defense. It has been determined that phy...
