Sugars as Energy Storage Molecules

10.4K
Sugar (a simple carbohydrate) metabolism (chemical reactions) is a classic example of the many cellular processes that use and produce energy. Living things consume sugar as a major energy source because sugar molecules have considerable energy stored within their bonds. Consumed carbohydrates have their origins in photosynthesizing organisms like plants. During photosynthesis, plants use the energy of sunlight to convert carbon dioxide gas into sugar molecules, like glucose. Because this...

C4 Pathway and CAM

50.9K
Most plants use the C3 pathway for carbon fixation. However, some plants, such as sugar cane, corn, and cacti that grow in hot conditions, use alternative pathways to fix carbon and conserve energy loss due to photorespiration. Photorespiration is the process that occurs when the oxygen concentration is high. Under such conditions, the rubisco enzyme in the Calvin cycle binds O2 instead of CO2, which halts photosynthesis and consumes energy.

Phloem and Sugar Transport

41.3K
Like many living organisms, plants have tissues that specialize in specific plant functions. For example, shoots are well adapted to rapid growth, while roots are structured to acquire resources efficiently. However, sugar production is primarily restricted to the photosynthetic cells that reside in the leaves of angiosperm plants. Sugar and other resources are transported from photosynthetic tissues to other specialized tissues by a process called translocation.

Cellulose and Pectic Polysaccharides

5.5K
 Every plant cell has a cell wall that protects the cell, provides structural support, and gives the cell shape. Cellulose, the main structural component of the plant cell wall, makes up over 30% of plant matter. It is the most abundant organic compound on earth.  Cellulose is an unbranched polysaccharide composed of linear chains of glucose molecules linked by β (1→4) glycosidic bonds.
As a cell matures, its cell wall specializes according to its type. For example, the...

Area of Science:

  • Plant Biotechnology
  • Molecular Biology
  • Agricultural Science

Background:

  • Genetic transformation is crucial for sugarcane crop improvement and developing it as a bio-factory.
  • Traditional breeding methods can be complemented by genetic engineering for enhanced crop traits.

Purpose of the Study:

  • To establish an efficient Agrobacterium tumefaciens-mediated genetic transformation protocol for sugarcane.
  • To demonstrate the utility of this protocol in a commercially important sugarcane cultivar.

Main Methods:

  • Embryogenic callus from immature sugarcane leaf whorls was used as the target material.
  • Agrobacterium tumefaciens strain AGL1 carrying the nptII gene was employed for transformation.
  • Selection of transgenic cells was performed using geneticin and paromomycin at specific concentrations.

Main Results:

  • Successful genetic transformation of sugarcane cultivar CP-88-1762 was achieved.
  • An effective selection system using geneticin and paromomycin suppressed non-transgenic plant development.
  • The transformation efficiency was reported as two independent transgenic plants per gram of callus.

Conclusions:

  • Agrobacterium tumefaciens-mediated transformation is a viable method for genetically modifying sugarcane.
  • This protocol provides a foundation for future genetic improvements in commercially relevant sugarcane varieties.
  • Transgenic sugarcane holds potential for producing value-added products, transforming the crop into a bio-factory.
