Frequency-dependent Selection01:21

Frequency-dependent Selection

20.1K
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Phloem and Sugar Transport

28.6K
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.

Types of Selection

37.5K
Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...

Bioreactor Controls-III

Strain improvement is a foundational strategy in industrial microbiology aimed at maximizing microbial productivity, particularly because natural isolates typically yield commercially valuable products in very low concentrations. Although optimizing the culture medium and environmental conditions can improve yields, these adjustments are inherently limited by the organism’s genetic potential. As a result, the focus shifts toward genetic modifications to enhance biosynthetic capacity. The...

C4 Pathway and CAM01:27

C4 Pathway and CAM

38.0K
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.

Sugars as Energy Storage Molecules01:10

Sugars as Energy Storage Molecules

7.2K
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...

Summary

This study introduces a mass selection reservoir (MSR) for breeding clonally propagated crops like sugarcane. The MSR method shows promise, matching commercial clone performance after just two generations.

Area of Science:

  • Agricultural Science
  • Plant Breeding
  • Genetics

Background:

  • Clonally propagated crops often face challenges in breeding due to limited genetic diversity.
  • Traditional breeding methods may not fully exploit the potential of heterogeneous populations for crop improvement.

Purpose of the Study:

  • To adapt the mass reservoir technique for breeding clonally propagated crops.
  • To evaluate the effectiveness of a mass selection reservoir (MSR) in sugarcane breeding.
  • To compare different artificial selection strategies within the MSR framework.

Main Methods:

  • Developed a two-phase breeding approach: sexual recombination for diversity, followed by selection in a genotypically heterogeneous mass selection reservoir (MSR).
  • Implemented artificial selection within the MSR for sugarcane in Fiji, focusing on sugar concentration and stalk weight.
  • Compared linear (L) and multiplicative (M) selection methods based on these criteria.

Main Results:

  • Significant clonal variation was observed at the single stalk level, with sugar concentration being highly repeatable.
  • After two generations, the MSR population performance equaled that of the best commercial sugarcane clone (Ragnar).
  • Minimal differences in population performance were observed between the linear and multiplicative selection methods.

Conclusions:

  • The mass selection reservoir (MSR) is a viable and effective method for breeding clonally propagated crops, including sugarcane.
  • The MSR approach can rapidly generate populations with performance comparable to elite commercial varieties.
  • Both linear and multiplicative selection strategies show potential within the MSR framework for sugarcane improvement.
