Evolutionary Relationships through Genome Comparisons02:54

Evolutionary Relationships through Genome Comparisons

5.7K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Overview of Transposition and Recombination

15.3K
Transposons make up a significant part of genomes of various organisms. Therefore, it is believed that transposition played a major evolutionary role in speciation by changing genome sizes and modifying gene expression patterns. For example, in bacteria, transposition can lead to conferring antibiotic resistance. Movement of transposable elements within the genetic pool of pathogenic bacteria can aid in transfer of antibiotic-resistant genetic elements. In eukaryotes, transposons can carry out...

Gene Evolution - Fast or Slow?

7.0K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

Transgenic Plants02:50

Transgenic Plants

7.2K
Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Light Acquisition02:16

Light Acquisition

8.4K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Plant Breeding and Biotechnology

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Area of Science:

  • Molecular evolution
  • Genomics
  • Bioinformatics

Background:

  • Molecular evolution studies require specific gene data, which is challenging to extract from vast public repositories.
  • The THI1 gene encodes thiamine thiazole synthase, essential for vitamin B1 precursor synthesis and primary metabolism.

Purpose of the Study:

  • To elucidate the evolutionary history and trends of the THI1 gene across Archaea and Eukarya.
  • To investigate the conservation, regulation, and expression patterns of THI1 homologs.

Main Methods:

  • Searched public genome repositories for THI1 homologs (702 identified).
  • Analyzed gene structure, cis-regulatory sites, and transcriptome data (484 datasets).
  • Examined evolutionary pressures and regulatory mechanisms like TPP riboswitch sites.

Main Results:

  • The THI1 gene is preserved in plants, targeted to chloroplasts, and shows dual posttranscriptional regulation in basal groups.
  • Two conserved cis-regulatory motifs were found across all plant lineages.
  • THI1 homolog expression is linked to light/dark cycles and exhibits tissue-specific patterns.

Conclusions:

  • Public data repositories offer valuable resources for exploring evolutionary trends of genes like THI1.
  • The study provides insights into the evolutionary trajectory and regulatory strategies of a key metabolic gene.
