The Fluid Mosaic Model01:34

The Fluid Mosaic Model

177.7K
The fluid mosaic model was first proposed as a visual representation of research observations. The model comprises the composition and dynamics of membranes and serves as a foundation for future membrane-related studies. The model depicts the structure of the plasma membrane with a variety of components, which include phospholipids, proteins, and carbohydrates. These integral molecules are loosely bound, defining the cell’s border and providing fluidity for optimal function.

Scientists identified the plasma membrane in the 1890s and its principal chemical components (lipids and proteins) by 1915. The model for plasma membrane structure, proposed in 1935 by Hugh Davson and James Danielli, was the first model to be widely accepted in the scientific community. The model was based on the plasma membrane's "railroad track" appearance in early electron micrographs. Davson and Danielli theorized that the plasma membrane's structure resembled a sandwich...

Position-effect Variegation

In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.

Protein Complex Assembly02:41

Protein Complex Assembly

16.7K
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types.  Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.
Many viruses self-assemble into a fully functional unit using the infected host cell to...

Meiosis II01:57

Meiosis II

208.1K
Meiosis II is the second and final stage of meiosis. It relies on the haploid cells produced during meiosis I, each of which contain only 23 chromosomes—one from each homologous initial pair. Importantly, each chromosome in these cells is composed of two joined copies, and when these cells enter meiosis II, the goal is to separate such sister chromatids using the same microtubule-based network employed in other division processes. The result of meiosis II is two haploid cells, each...

Summary

A new virus, tuberose mild mosaic potyvirus (TMMV), was identified in tuberose plants. This potyvirus is mechanically transmissible and aphid-borne, distinct from other known potyviruses.

Area of Science:

  • Plant Virology
  • Molecular Biology
  • Agricultural Science

Background:

  • Tuberose (Polianthes tuberosa) is susceptible to viral infections.
  • Mild mosaic symptoms were observed on tuberose leaves and peduncles.

Purpose of the Study:

  • To isolate and characterize the virus causing mild mosaic symptoms in tuberose.
  • To determine the taxonomic position of the isolated virus within the Potyvirus genus.

Main Methods:

  • Mechanical transmission and aphid transmission studies (Myzus persicae).
  • Electron microscopy for particle morphology and size determination.
  • Analysis of cytoplasmic inclusions, capsid protein, and serological assays (SDS-immunodiffusion).
  • RT-PCR for sequence amplification and confirmation.

Main Results:

  • A flexuous, rod-shaped virus (Tbr1 isolate) with a mean length of 750 nm was isolated.
  • Cytoplasmic inclusions characteristic of potyviruses were observed.
  • The virus showed no cross-reactivity with antisera of 22 known potyviruses.
  • RT-PCR confirmed the presence of a 2-kb DNA product, consistent with potyviruses.

Conclusions:

  • Tbr1 represents a unique species within the genus Potyvirus.
  • The virus was officially designated as tuberose mild mosaic potyvirus (TMMV).
  • TMMV is distinct from other characterized potyviruses based on biological, morphological, and molecular data.
