The genomic footprint of climate adaptation in Chironomus riparius.
The gradual heterogeneity of climatic factors poses varying selection pressures across geographic distances that leave signatures of clinal variation in the genome. Separating signatures of clinal adaptation from signatures of other evolutionary forces, such as demographic processes, genetic drift and adaptation, to nonclinal conditions of the immediate local environment is a major challenge. H...
متن کاملپرورش انبوه لاروهای (Chironomus riparius (Dip.: Chironomidae
لاروهای آبزی پشهی Chironomus riparius Meigen یکی از منابع غذایی غنی در پرورش ماهیان میباشد. کمیت و کیفیت مادهی غذایی که در پرورش این لاروها استفاده میشود، بر رشد و نمو دورهی لاروی این پشه تأثیرگذار است. این مطالعه شامل بررسی اثر جیرههای غذایی مختلف (کود مرغی، پودر سویا و سبوس برنج) با مقادیر وزنی متفاوت (1، 3 و 5 گرم) بر رشد و نمو لاروها، تعیین زمان مناسب برداشت لاروها در دماهای مختلف (...
متن کاملRapid Cycling Genomic Selection in a Multiparental Tropical Maize Population
Genomic selection (GS) increases genetic gain by reducing the length of the selection cycle, as has been exemplified in maize using rapid cycling recombination of biparental populations. However, no results of GS applied to maize multi-parental populations have been reported so far. This study is the first to show realized genetic gains of rapid cycling genomic selection (RCGS) for four recombi...
متن کاملChironomus riparius (Diptera) genome sequencing reveals the impact of minisatellite transposable elements on population divergence.
Active transposable elements (TEs) may result in divergent genomic insertion and abundance patterns among conspecific populations. Upon secondary contact, such divergent genetic backgrounds can theoretically give rise to classical Dobzhansky-Muller incompatibilities (DMI), thus contributing to the evolution of endogenous genetic barriers and eventually causing population divergence. We investig...
متن کاملA Genomic Selection Index Applied to Simulated and Real Data
A genomic selection index (GSI) is a linear combination of genomic estimated breeding values that uses genomic markers to predict the net genetic merit and select parents from a nonphenotyped testing population. Some authors have proposed a GSI; however, they have not used simulated or real data to validate the GSI theory and have not explained how to estimate the GSI selection response and the...
