![]() Our method enables the efficient and seamless assembly of short DNA blocks with dinucleotide overhangs through a simple ligation process. The Shuffle Optimizer program and these protocols will be useful to anyone desiring to perform any of the nucleotide homology-dependent shuffling methods. We present an overhang-based DNA block shuffling method to create a customized random DNA library with flexible sequence design and length. In addition we also include sections on optimal primer design for DNA shuffling and library construction, a smallvolume ultrasonicator method to create sheared DNA, and finally a method to reassemble the sheared fragments and recover and clone the library. Shuffle Optimizer is written in the Python computer language and increases the nucleotide homology between two pieces of DNA desired to be shuffled together without changing the amino acid sequence. Here, we present a protocol to use our freely available and easy-to-use computer program, Shuffle Optimizer. The Shuffle Optimizer program and these protocols will be useful to anyone desiring to perform any of the nucleotide homology-dependent shuffling methods.ĪB - DNA shuffling is a powerful tool to develop libraries of variants for protein engineering.

The implications of these results for coral adaptation, along with future avenues of research based on current knowledge gaps, are discussed in the present work.īay L. Overall, these results suggest that changes in algal symbionts favouring heat tolerant associations are accompanied by changes in DNA methylation in the coral host. Interestingly, while differential gene body methylation was not correlated with gene expression, an enrichment in differentially methylated regions was evident in repetitive genome regions. trenchii) compared to all other comparisons. Remarkably, DNA methylation changes in response to heat stress were dependent on the dominant symbiont, with twice as many differentially methylated regions found in heat‐stressed corals hosting different symbionts (Cladocopium vs. Single‐base genome‐wide analyses showed significant modifications in DNA methylation concentrated in intergenic regions, introns and transposable elements. Symbiont composition was manipulated in the great star coral Montastraea cavernosa through controlled thermal bleaching and recovery, producing paired ramets of three genets dominated by either their native symbionts (genus Cladocopium) or the thermotolerant species (Durusdinium trenchi). ![]() This work studied the modifications in coral DNA methylation, an epigenetic mechanism involved in coral acclimatization, in response to symbiont manipulation and subsequent heat stress exposure. Yet, the mechanistic underpinnings and long‐term implications of these changes are poorly understood. AbstractAlgal symbiont shuffling in favour of more thermotolerant species has been shown to enhance coral resistance to heat‐stress.
