Unravelling arthropod genome diversity more than 500 million years of evolution, Comparative analysis of 76 species covering 500 million years of evolution shows dynamic genomic changes that highlight key success factors and open up many new fields of research.
Arthropods represent the most diverse and diverse group of animals on earth, with many adaptations during more than 500 million years of evolution, which allows them to exploit all important ecosystems. They play an important role in the healthy ecology of our planet and are useful and dangerous for human success by polluting and recycling organic waste or destroying seeds and spreading disease and now researchers Unravelling arthropod genome diversity more than 500 million years of evolution.
By sorting and comparing their genomes, we can begin to identify some of the most important genetic factors for the success of their evolution.
The i5k initiative to sort and annotate the genomes of 5,000 species of insects and other arthropods was launched in 2011 in a letter to science. From the beginning, this initiative aimed to help develop new genome resources for understanding molecular biology and the evolution of arthropods.
Since then, i5k has developed into a broad community of scientists who use genomics to study insects and other arthropods in many different contexts – from basic animal biology to environmental and environmental influences to their effects on human health and agriculture2.
To start i5k, Baylor College of Medicine, led by Stephen Richards, has launched a pilot project to sort, collect and comment on the genomes of 28 different arthropods, which have been carefully selected by 787 community nominations.
Identifying and commenting on thousands of genes from the i5k pilot significantly enhances our current genomic arthropod sample.
The combination with the previously sorted genome allows researchers to carry out a comprehensive comparative analysis of 76 different species, including flies, butterflies, moths, beetles, bees, ants, wasps, insects, thrips, lice, cockroaches, cockroaches, termites, and honey bee. Horses, damselflies, feathers, crustaceans, millipedes, spiders, ticks, ticks, and scorpions. One researcher explained.
The team’s analysis focuses on tracking the history of gene development to assess changes in gene content and structure over 500 million years.
This allows a family of genes to be identified that have increased or decreased significantly, or have appeared or disappeared, or whose protein domains have been rearranged between and within each of the major arthropod subgroups. Proteins that encode a family of genes involved in functions related to digestion, chemical protection, and development and chitin remodin, the main component of the arthropod exoskeleton, have been found to be the most dynamic.
Adaptation of the digestive process and the mechanism to neutralize hazardous chemicals undoubtedly serve arthropods which conquer various environmental niches.
Perhaps more importantly, the flexibility that comes with a segmented body plan and dynamically reshaped exoskeleton has enabled them to develop by physically adapting to new ecosystems.
The newly developed gene family also reflects functions known to be important for various arthropod groups, such as training and visual behavior, detection of pheromones and aromas, nerve activity and wing development. They can increase the ability to use food or promote recognition and communication between species. Instead, only a few changes were found in the ancestors of insects that experienced complete metamorphosis: dramatic changes from the shape of the teenager to fully mature (like a caterpillar like a butterfly).
This is traditionally considered an important step in the evolution of insects from the early stages of their development to the stages of nymphs to the adult stage.
Some detailed genomic studies of individual i5k species have focused on their interesting biological traits, such as nutritional ecology and insect development biology, insecticide resistance, blood supply and sex traumatic trigger woodpeckers, horizontal transmission of bacterial genes and bacterial genes from long-horned Asian beetles and interactions between parasites and host and potential sheep vaccines.
The combined analysis shows that dynamically changing and emerging gene families will stimulate new fields of research. We can use this hypothesis in the laboratory to directly study how genomes are converted to visible morphology with a resolution that no other group of animals matches.
This new resource is making a significant step in building a complete genome catalog of life on our planet, and with more than one million arthropod species and an estimated seven-fold estimate, much remains to be discovered.
The goals of EBP also include human well-being, where the role of arthropods is clear and hidden benefits tend to be significant, as well as protecting biodiversity and understanding ecosystems where reports that interfere with decreases in number give priority to arthropods.
For this reason, the completion of the i5k pilot is an important moment to increase efforts to develop a comprehensive genome catalog of our planet’s life.
