  • plasticity
  • Adventitious root (AR) formation is a developmental process which on the one hand reflects the great plasticity of plants to adjust to stressful environmental conditions and to regenerate plant structures on the same individual independent of sexual reproduction. (frontiersin.org)
  • natural hormone
  • New research in rats suggests the possibility of bioengineering artificial ovaries in the lab to provide a safer, more natural hormone replacement therapy for women. (medicalxpress.com)
  • nutrients
  • Plant cells also contain chlorophyll , a chemical compound that interacts with light in a way that enables plants to manufacture their own nutrients rather than consuming other living things as animals do. (wikipedia.org)
  • Auxins
  • Auxins used in early grow, promote adventurous rooting, help relieve plant stress, and promote plant health/vigor. (icmag.com)
  • It is the best known of the auxins, and has been the subject of extensive studies by plant physiologists. (thomassci.com)
  • animal hormones
  • Animal hormones include steroids , eicosanoids (e.g. derivatives of arachidonic acid, lipoxins, and prostaglandins ), and amino acid derivatives (e.g. melatonin and thyroxine ). (biology-online.org)
  • intercellular
  • Many of our current concepts about intercellular communication in plants have been derived from similar studies in animals, in which two main systems evolved: the nervous system and endocrine system. (springer.com)
  • chemicals
  • They are naturally produced within plants, though very similar chemicals are produced by fungi and bacteria that can also affect plant growth. (wikipedia.org)
  • Plants lack glands to produce and store hormones, because, unlike animals-which have two circulatory systems ( lymphatic and cardiovascular ) powered by a heart that moves fluids around the body-plants use more passive means to move chemicals around their bodies. (wikipedia.org)
  • Plants utilize simple chemicals as hormones, which move more easily through their tissues. (wikipedia.org)
  • they can regulate the amount of chemicals used to biosynthesize hormones. (wikipedia.org)
  • Certain chemicals such as paclobutrazol, a plant growth regulator, inhibit gibberellin synthesis, thereby slowing or stopping vertical growth and initiating early fruitset production. (maximumyield.com)
  • Like animals, plants produce chemicals called hormones which are produced in one part of the plant to signal cells in another part of the plant to respond. (wikipedia.org)
  • Hormones are chemicals which are released by cells that affect cells in other parts of the body. (wikispaces.com)
  • concentration
  • Changes in concentration or usage of isomeric hormones has differing effects, thus the multiple effects seen from one hormone depending on the application method strength. (icmag.com)
  • Thus, higher hormone concentration alone can not trigger the negative feedback mechanism. (wikispaces.com)
  • analyses
  • Currently there is no computational tool to determine the relative activity of these hormones that can be applied to transcriptome analyses in soybean. (beds.ac.uk)
  • cell
  • A hormone (from Greek ὁρμή, "impetus") is a chemical released by a cell or a gland in one part of the body that sends out messages that affect cells in other parts of the organism. (primidi.com)
  • Only a little amount of hormone is required to alter cell metabolism. (primidi.com)
  • Unlike in animals (in which hormone production is restricted to specialized glands ) each plant cell is capable of producing hormones. (wikipedia.org)
  • Hormones may be hydrophilic, like insulin , in which case the receptors are on the cell surface or lipophilic, like the steroids, where the receptor can be intracellular. (biology-online.org)
  • Closely related fields include plant morphology (structure of plants), plant ecology (interactions with the environment), phytochemistry ( biochemistry of plants), cell biology , genetics, biophysics and molecular biology . (wikipedia.org)
  • For example, plant cells have a cell wall which restricts the shape of plant cells and thereby limits the flexibility and mobility of plants. (wikipedia.org)
  • These hormones are usually transported to a different cell to elicit a response. (bartleby.com)
  • Prior to extraction, plant material must be homogenised to break the cell walls in the tissues (Harrison 2011 ) and thus allow any hormones present to migrate to an appropriate extraction solvent. (springer.com)
  • The discovery of jasmonoyl- L -isoleucine (JA-Ile) as the major bioactive form of the hormone highlights the need to understand biochemical and cell biological processes underlying JA-Ile homeostasis. (frontiersin.org)
  • Most hormones initiate a cellular response by initially combining with either a specific intracellular or cell membrane associated receptor protein. (wikispaces.com)
  • For many hormones, including most protein hormones, the receptor is membrane associated and embedded in the plasma membrane at the surface of the cell. (wikispaces.com)
  • For hormones such as steroid or thyroid hormones, their receptors are located intracellularly within the cytoplasm of their target cell. (wikispaces.com)
  • In order to bind their receptors these hormones must cross the cell membrane. (wikispaces.com)
  • The combined hormone-receptor complex then moves across the nuclear membrane into the nucleus of the cell, where it binds to specific DNA sequences, effectively amplifying or suppressing the action of certain genes, and affecting protein synthesis.However, it has been shown that not all steroid receptors are located intracellularly, some are plasma membrane associated.

  • thus
  • Thus, sound knowledge of the analytical and chemical principles underlying the extraction, purification, identification and quantification of plant hormones is essential for their accurate and precise determination. (springer.com)
  • Thus, exogenous treatments or transgenic approaches for higher SL bioaccumulation can be potential strategies for developing multiple abiotic stress tolerance in crops and plants. (springer.com)
  • amino acids
  • They can store them in cells, inactivate them, or cannibalise already-formed hormones by conjugating them with carbohydrates , amino acids , or peptides . (wikipedia.org)
  • substances
  • However, this is highly challenging since trace amounts of all of these substances are present in highly complex plant matrices. (springer.com)
  • The term â plant growth factorâ is typically used for plant hormones or substances of comparable impact that area unit administered to plants. (omicsonline.org)
  • For example, the "hormone" Provera is made from the same substances that natural progesterone is made from, but the molecular configuration of it is changed in the laboratory so that it is not identical to anything found in nature. (pathmed.com)
  • Pathway
  • The magnitude and significance of these changes are used to determine a pathway score for a phytohormone for a given comparison in a microarray experiment. (beds.ac.uk)
  • Thyroid
  • Thyroid hormone therapy significantly resolves fibrosis, or scarring, in the lungs of mice, increasing their survival from disease, a Yale-led study shows. (medicalxpress.com)
  • effects
  • Women are twice as likely as men to have asthma, and this gender difference may be caused by the effects of sex hormones on lung cells. (medicalxpress.com)
  • They also need to disengage the effects that hormones have when they are no longer needed. (wikipedia.org)
  • You may want to consider other hormones that reportedly have similar effects (and are much less expensive), such as DHEA or pregnenolone. (drlam.com)
  • pituitary gland
  • Resistance exercise like weight training causes the spurts of growth hormone releases from the pituitary gland. (drlam.com)
  • Even if you lift at 70-85% of your maximal lift capacity, there is still a three to four-fold increase of growth hormone from your pituitary gland according to certain studies. (drlam.com)
