Fruit Development, Structure, and Function01:58

Fruit Development, Structure, and Function

25.2K
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

Viral Recombination00:57

Viral Recombination

25.1K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Viral Structure00:56

Viral Structure

74.5K
Viruses are extraordinarily diverse in shape and size, but they all have several structural features in common. All viruses have a core that contains a DNA- or RNA-based genome. The core is surrounded by a protective coat of proteins called the capsid. The capsid is composed of subunits called capsomeres. The capsid and genome-containing core are together known as the nucleocapsid.

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...

Protein Complexes with Interchangeable Parts01:57

Protein Complexes with Interchangeable Parts

2.9K
Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.
The SCF ubiquitin ligase is a protein complex of five individual proteins. This complex attaches ubiquitin to other target proteins to mark them for degradation. In order...

Complex Numbers01:29

Complex Numbers

303
The real number system cannot represent the square root of a negative number, which restricts solutions for certain equations, such as quadratics with negative discriminants. To address this, the complex number system was developed, introducing the imaginary unit i, where i = √(-1). This extension allows for the representation of all roots, including those involving negative radicands.A complex number is written in the form x + yi, where x and y are real numbers. Here, x represents the...

Area of Science:

  • Viticulture
  • Plant Pathology
  • Molecular Virology

Background:

  • Grapevine (Vitis spp.) cultivation has ancient origins, with diverse cultivars classified by berry color.
  • Grapevines are susceptible to various pests and pathogens, including graft-transmissible agents.
  • Grapevine leafroll disease (GLD) is a significant viral disease impacting global grape and wine industries.

Purpose of the Study:

  • To provide a comprehensive overview of the current knowledge on grapevine leafroll disease (GLD).
  • To discuss the biology and epidemiology of GLD, considering its complexity and associated viruses.
  • To outline current management strategies for controlling GLD in vineyards worldwide.

Main Methods:

  • Literature review synthesizing existing research on GLD.
  • Analysis of the biological and epidemiological factors contributing to GLD spread.
  • Compilation of current vineyard management practices for GLD control.

Main Results:

  • GLD is the most widespread and economically damaging viral disease affecting grapevines globally.
  • Understanding GLD is challenged by its complex viral etiology and varied symptom expression in different cultivars.
  • Effective management strategies are crucial for mitigating the economic impact of GLD.

Conclusions:

  • GLD poses a significant and growing threat to the global grape and wine industry.
  • Further research is needed to fully elucidate the complexities of GLD and its associated viruses.
  • Integrated management approaches are essential for sustainable control of GLD in viticulture.
