Identification of Plasmodesmal Localization Sequences in Proteins In Planta
Published on: August 15, 2017
Summary
Phytoplasma classification using molecular analyses clarifies plant disease origins. Understanding phytoplasma-insect vector relationships is key to their evolutionary divergence and disease specificity.
Area of Science:
- Plant pathology
- Microbiology
- Molecular biology
Background:
- Many plant diseases were historically attributed to phytoplasmas before precise classification methods were available.
- Molecular analyses now enable detailed assessment of phytoplasma-disease relationships.
Purpose of the Study:
- To investigate the links between phytoplasma classification and specific plant diseases.
- To explore the evolutionary origins of pathogenicity and plant responses to phytoplasmas.
Main Methods:
- Utilized molecular analyses for phytoplasma delineation and classification.
- Analyzed data on phytoplasma-insect vector interactions and host ranges.
- Examined conserved phytoplasma genes for evolutionary insights.
Main Results:
- Findings support a common ancestral origin for pathogenicity genes in phytoplasmas.
- Plant host ranges are influenced by vector transmission and feeding preferences.
- Small genetic variations in conserved genes may indicate distinct phytoplasma gene pools.
- Disease diagnosis reliability requires empirical case study for each syndrome.
Conclusions:
- Some plant diseases are linked to phytoplasma taxa at the 16S rRNA group level.
- Other diseases are associated with phytoplasma taxa below the 16S rRNA group level.
- Phytoplasma-insect vector dynamics are crucial for understanding phytoplasma evolution and disease patterns.

01:24Bacterial Phylum Tenericutes
The phylum Tenericutes, which includes the single class Mollicutes, comprises bacteria that lack cell walls. The term "Mollicutes" derives from the Latin word mollis, meaning "soft." These organisms are among the smallest known and are commonly referred to as mycoplasmas due to the prominence of the genus Mycoplasma, which includes well-known human pathogens. Despite their inability to stain gram-positively (a result of their lack of cell walls), mycoplasmas are phylogenetically related to the...
01:27Diversity of Protists II
Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
01:28Fungal Phylum Microsporidia
Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
01:09Microbe-Plant Interactions
Microbe-plant interactions represent a dynamic spectrum of associations shaped by intricate chemical signaling. These interactions can be neutral, beneficial, or detrimental, and profoundly influence plant physiology, growth, and ecosystem function. The plant microbiome, comprising bacteria, fungi, archaea, protists, and viruses, plays a pivotal role in mediating these effects through surface colonization, internal colonization, or systemic symbiosis.Mutualistic associations, particularly with...
01:28Plasmids
Plasmids are extrachromosomal DNA molecules found in bacteria, archaea, and some eukaryotic microbes like yeast. These small, circular DNA structures typically contain fewer than 30 genes, although some may exist linearly. Plasmids vary in their number within a cell, known as copy number. Single-copy plasmids are present in one copy per cell and multi-copy plasmids are present in multiple copies, reaching over 100 copies per cell.Plasmids usually replicate independently of the chromosomal DNA...
01:27Overview of Protists
Protists are diverse eukaryotic microorganisms that lack the specialized tissues of plants and animals and the chitinous cell walls of fungi. Their early divergence within Eukarya resulted in structural, functional, and ecological diversity. They are classified into supergroups such as Archaeplastida, Excavata, Amoebozoa, Rhizaria, Alveolata, and Stramenopiles, determined through genetic analysis and structural similarities.Structural and Functional AdaptationsProtists have various adaptations...
