Dunaliella salina - Overview

Image
                 Dunaliella salina Dunaliella salina is a unicellular microalgae belong to division Chlorophyta . It is found in salinity environments such as salted brines, salt evaporation ponds, and hypersaline lakes  .It is able to tolerate varying NaCl concentrations, ranging from 0.2% to approximately 35% . Thus, Dunaliella salina is a hyper-halotolerant organism found in high densities in saline lakes.  The ability to tolerate high salt concentrations is advantageous, since competition is minimal in high salt concentration areas.  How D.salina   tolerate high salt concentration? D. salina has adapted to survive in high salinity environments by accumulating glycerol to balance osmotic pressure. Note :  D. salina is also adapted to solar radiation using β-carotene to protect against ionizing energy.                 Red Colour of Salt Brines  Dunaliella salina...

  Difference between anthocyanin and anthocyanidins
Anthocyanin in berry skin of grapes

Similarities between anthocyanin and anthocyanidins:

  • Anthocyanin and anthocyanidin are two types of red-blue plant pigments.
  • Both anthocyanin and anthocyanidin can be found in fruits, flowers, leaves, stems, and roots of higher plants.
  • Both anthocyanin and anthocyanidin are flavonoids.
  • The basic core of both anthocyanin and anthocyanidin is the flavylium
  • Both anthocyanin and anthocyanidin depend upon the pH.
  • Both anthocyanin and anthocyanidin are composed of antioxidant properties.
  • Both anthocyanin and anthocyanidin are used as food colorants and pharmaceutical components.

Parthenogenesis

    Parthenogenesis * Mode of reproduction in which the female gamete develops into embryo without any genetic contribution from the male gamete is called parthenogenesis. * The individual formed from parthenogenesis is called parthenot. *It is also called virgin birth. * It is always monoparental. *Term parthenogenesis is coined by Richar Owen .                            Occurence  Parthenogenesis occur uncertain orders of  insecta: Hymenoptera, Coleoptera ,Homoptera,Rotifera and lower crustaceans .It is also reported in certain vertebrates; in domestic turkey.It occurs sporadically in large number of plants .               Types of parthenogenesis Two types: 1)Natural parthenogenesis 2) Artificial parthenogenesis                                Natural  First reported by Bonnet...
