  • Sixteen chemical elements are required for the growth of all plants: carbon, oxygen, and hydrogen (these three are obtained from carbon dioxide and water), plus nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, zinc, copper, boron, molybdenum, and chlorine.
  • Fertility levels can vary from a deficiency to a sufficiency, or even toxicity (too much), of one or more nutrients.
  • soil considered fertile in all other ways could have levels of available potassium too low for optimum plant growth

  • Typically, stems show positive phototropism (movement toward the light), whereas roots exhibit negative phototropic movement (away from the source of light).
  • Arabidopsis contains two phototropins referred to as phot1 and phot2. Mutants of Arabidopsis lacking both phototropins lose their phototropic responsiveness
  • Phototropic response
  • ...10 more annotations...
  • phototropins control the movement of chloroplasts
  • these responses serve to enhance the photosynthetic
  • Phototropins, like photoreceptor pigments associated with mammalian vision, comprise many amino acids (900–1000) that form the main structure of the protein (the apoprotein) to which an accessory chemical cofactor is bound that can absorb light and impart color (the chromophore)
  • a small fraction of the receptor pool is rapidly internalized (within minutes) upon blue light irradiation
  • Phototropins are typically associated with the plasma membrane
  • However, the biological significance
  • As light passes through the stem, it becomes progressively diffracted, thereby generating a gradient of phototropin activation across the organ, with the highest level of activity occurring on the irradiated side
  • In some plant species, including the fern Adiantum capillus-veneris, phototropism and chloroplast movement are induced by red light as well as blue.
  • novel
  • The presence of such a hybrid photoreceptor is proposed to enhance light sensitivity and aid the prevalence of species such as ferns in low light conditions

Hypoxia in the Northern Gulf of Mexico - 1 views

shared by Judi Crouch on 12 Apr 10 - Cached
  • Hypoxia, or oxygen depletion, is an environmental phenomenon where the concentration of dissolved oxygen in the water column decreases to a level that can no longer support living aquatic organisms.
  • Hypoxic and anoxic (no oxygen) waters have existed throughout geologic time, but their occurrence in shallow coastal and estuarine areas appears to be increasing as a result of human activities (Diaz and Rosenberg, 1995). The largest hypoxic zone currently affecting the United States, and the second largest hypoxic zone worldwide, occurs in the northern Gulf of Mexico adjacent to the Mississippi River on the Louisiana/Texas continental shelf.
  • What causes hypoxia? Major events leading to the formation of hypoxia in the Gulf of Mexico include: Freshwater discharge and nutrient loading of the Mississippi River Nutrient-enhanced primary production, or eutrophication Decomposition of biomass by bacteria on the ocean floor Depletion of oxygen due to stratification
  • ...5 more annotations...
  • Mississippi River nutrient concentrations and loading to the adjacent continental shelf have greatly changed in the last half of the 20th century. During this time there has been a marked increase in the concentration of nitrogen and phosphorous in the Lower Mississippi River. This increase has been attributed to the increased use of nitrogen and phosphorous fertilizers,
  • Eutrophication
  • eutrophication initiates a massive growth of phytoplankton on the water’s surface.
  • This stratification leaves the bottom layer isolated from the surface layer and cut off from a normal resupply of oxygen from the atmosphere.
  • Hypoxia was first documented in the northern Gulf of Mexico off the Louisiana coast in 1972.

  • Plants require 13 mineral nutrient elements for growth
  • Macronutrients (nitrogen, phosphorus, potassium, calcium, magnesium and sulfur) are plant nutrients required in the largest amount in plants. Micronutrients (iron, copper, manganese, zinc, boron, molybdenum and chlorine) are required in relatively smaller amounts. Additional mineral nutrient elements which are beneficial to plants but not necessarily essential include sodium, cobalt, vanadium, nickel, selenium, aluminum and silicon

      Nutrients (in the soid) are needed either in large amounts (macronutrients), medium amounts (micronutrients), or in trace amounts
  • A nutrient deficiency occurs when the nutrient is not in sufficient quantity to meet the needs of the growing plant. Nutrient toxicity occurs when a plant nutrient is in excess and decreases plant growth or quality
  • Five types of deficiency or toxicity symptoms are observed:

  • (Table 5)
  • Hormones are produced naturally by plants, while plant growth regulators are applied to plants by humans

      This is interesting because it shows you that if you want to manipulate hormones in an experiment you can use plant growth regulators to mimic the action of hormones.
  • ...3 more annotations...
  • There are five groups of plant-growth-regulating compounds: auxin, gibberellin (GA), cytokinin, ethylene, and abscisic acid (ABA).
  • Ethylene is unique in that it is found only in the gaseous form. It
  • induces ripening, causes leaves to droop (epinasty) and drop (abscission), and promotes senescence.
    • Pascale Michelon
      Pascale Michelon on 11 Apr 10
       
      The effects of ethylene (promotion of both aging/death and ripening) may explain why just one bad apple in a basket may spoil the whole bunch.
  • Pascale Michelon on 11 Apr 10
     
    Plant hormones and growth regulators are chemicals that affect flowering; aging; root growth; killing of leaves; prevention or promotion of stem elongation; color enhancement of fruit; prevention of leafing and/or leaf fall; etc.
