PLANTS Tens of millions of years before humanity sowed its first crops, a about humbler organism was starting up its own large-scaleagricultural operations. Leaf-cutter pismire species depend on actively managed fungus farming to feed their teaming colonies.  The ants pertly sequenced genome, based on three male Atta cephalotes ants collected in Gamboa, Panama, and described in PLoS Geneticss February 10 issue, reveals a care profusey culled hereditary profile that has been adapted everywhere the millennia to survive and thrive in symbiosis with its prize fungus.  In comparison with other dirt ball genomes, the fungus-farming ants genome (estimated to have just everywhere 18,000 genes) appears to have been pruned back over the years. Presumably, the ants have lost these genes because of their dependency on the fungus, Garret Suen, a bacteriologist at the University of Wisconsin-Madison, and study co-author, said in a ready statement. They dont need these pr oteins kicking around any more.  The genetic regions that be to have been most heavily trimmed are those middleman up to food digestion. The ants are lacking, for instance, genes associated with nutrient acquisition and aminic astringent biosynthesis, the researchers noted in their paper. These genes appear to be no long-acting required because the fungus may provide these nutrients.

  The fungus that the ants grow in their colonies is make into handy food packets, known as gongylidia, sufficient of amino acids, carbohydrates, lipids, proteins and vitamins. Work is currently underway to sequence the genome of the farmed fungus as headspring as other microbes that are kn! own to live on in the symbiotic system. The genome allows us to understand interactions in this insect-microbial system, Cameron Currie, similarly a UW bacteriologist and paper co-author, said in a ready statement. It improves our force to understand the evolution of symbiosis.  Researchers also hope to poke deeper into the ants deoxyribonucleic acid to better understand the vast...If you want to get a full essay, order it on our website: BestEssayCheap.com
