Combinatorial Gene Control02:33

Combinatorial Gene Control

9.6K
Combinatorial gene control is the synergistic action of several transcriptional factors to regulate the expression of a single gene. The absence of one or more of these factors may lead to a significant difference in the level of gene expression or repression.
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...

Somatic Spinal Reflexes01:22

Somatic Spinal Reflexes

5.2K
Somatic spinal reflexes are rapid, involuntary muscular responses to external stimuli that involve the somatic musculature and the spinal cord.
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...

Overview of Somatic Sensory Pathways01:29

Overview of Somatic Sensory Pathways

8.6K
Somatic sensory or somatosensory pathways refer to the neural pathways that carry information related to touch, pressure, pain, temperature, and proprioception from the skin, muscles, tendons, and joints to the brain. These pathways involve several stages of processing and integration of sensory information.
The somatosensory system is divided into three main pathways: the dorsal (or posterior) column-medial lemniscus, spinothalamic (or anterolateral), and spinocerebellar pathways.
The dorsal...

Somatic to iPS Cell Reprogramming01:29

Somatic to iPS Cell Reprogramming

2.7K
Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012...

Major Somatic Sensory Pathways01:28

Major Somatic Sensory Pathways

2.9K
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...

Cancers Originate from Somatic Mutations in a Single Cell02:21

Cancers Originate from Somatic Mutations in a Single Cell

14.9K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

Area of Science:

  • Plant Biotechnology
  • Agricultural Science
  • Genetics

Background:

  • Somatic embryogenesis is a key technique for plant propagation and genetic improvement.
  • Developing efficient protocols for peanut (Arachis hypogaea L.) is crucial for crop enhancement.
  • Understanding genotypic influence on somatic embryogenesis is vital for optimizing peanut breeding.

Purpose of the Study:

  • To evaluate the efficacy of a somatic embryogenesis protocol across diverse peanut genotypes.
  • To identify genotype-specific variations in peanut plant development via somatic embryogenesis.
  • To determine the influence of genetic makeup on different stages of somatic embryogenesis in peanut.

Main Methods:

  • Utilized mature zygotic embryo-derived leaflets from sixteen peanut genotypes.
  • Applied a standardized multi-stage somatic embryogenesis protocol.
  • Assessed and compared response frequencies at each developmental stage.

Main Results:

  • The somatic embryogenesis protocol was effective across all sixteen peanut genotypes.
  • Significant genotypic variations were observed in embryogenic mass induction, embryo development, and plantlet conversion.
  • Root meristem differentiation and radicle emergence showed less genotype dependency compared to other stages.

Conclusions:

  • Somatic embryogenesis in peanut is largely dependent on the genotype of the original plant.
  • Genotype significantly influences the success of somatic embryo development and conversion to plantlets.
  • Further research into genotype-specific factors is needed to improve peanut somatic embryogenesis efficiency.
