Different ploidies poplar sequencing

Polyploids generally show vegetative growth superiority, higher biological yield, and enhanced resistance compared to diploids, which may become a novel approach in plant breeding; however, the mechanisms underlying these traits remains unclear. Here, we developed and compared transcriptomic differences between newly synthesized Populus section Tacamahaca allotriploids and allotetraploids and their full-sib diploids using Illumina RNA-sequencing. Collectively, our study revealed valuable comparative transcriptome information on three different ploidies in Populus and provided a robust resource for investigating the function of genes associated with polyploid genotype differences, as well as improving the understanding of molecular regulatory mechanism underlying stomatal development in polyploids, and the poplar polyploidy system with clear and complete genetic backgrounds may use as a good models for studies in polyploidization advantage.
