Four plant hormones
WebEnvironmental stimuli for plants include light, gravity, water, changes in seasons and touch. Responses by the plant to environmental stimuli are known as tropisms. The five main types of plant hormones are Auxins, Gibberellins, Ethene, Cytokinins and ABA. These plant hormones are used for various reasons in agriculture and horticulture to ... Different hormones can be sorted into different classes, depending on their chemical structures. Within each class of hormone, chemical structures can vary, but all members of the same class have similar physiological effects. Initial research into plant hormones identified five major classes: abscisic acid, auxins, brassinosteroids, cytokinins and ethylene. This list was later expanded, and br…

WebThe enriched pathways in “Light/CK” and “Light/Dark” are more similar, including “circadian rhythm-plant”, “phenylpropanoid biosynthesis”, “photosynthesis-antenna proteins”, etc. The pathways present in all three comparison groups included “plant hormone signal transduction” and “starch and sucrose metabolism”.
Like auxins, cytokinins are a group of related molecules that regulate growth and development. However, the plant’s response to cytokinin is very different from the responses to auxin. Cytokinin comes from the word cytokinesis, which means cell division. You will learn about cytokinesis, specifically mitosis, in … See more Auxins are a group of related molecules that are involved in almost every aspect of the plant’s life cycle. Auxins stimulate growth through cell elongation, which is integral to the plant’s responses to environmental … See more Gibberellins, or gibberellic acid (GA), are a group of over 100 molecules that are primary regulators of stem elongation and seed germination. They were discovered during research on the cause of the “foolish seedling” … See more Ethylene is well known as the gaseous, ripening hormone. It also regulates seedling growth and the formation of root hairs, and can lead to epinasty — the bending of branches downwards. Many plants are sensitive … See more While GA facilitates seed germination, abscisic acid (ABA) inhibits it. Abscisic acid is a single molecule that regulates germination and the response of a plant to reduced water … See more WebEthylene is a plant hormone that affects ripening and rotting in plants. It is a particularly interesting plant hormone because it exists as a gas. No other plant hormone is gaseous! Ethylene can be produced in almost any part of a plant, and can diffuse through the plant’s tissue, outside the plant, and travel through the air to affect a ...
