Plasticity in ploidy: a generalized response to stress

摘要: Endoreduplication, the replication of genome without mitosis, leads to an increase in cellular ploidy organism over its lifetime, a condition termed 'endopolyploidy'. Endopolyploidy is thought play significant roles physiology and development through cellular, metabolic, genetic effects. While occurrence endopolyploidy has been observed widely across taxa, studies have only recently begun characterize manipulate with focus on ecological evolutionary importance. No compilation these examples implicating endoreduplication as generalized response stress thus far made, despite growing evidence supporting this notion. We review here recent literature stress-induced suggest that plants employ adaptive, plastic mitigate effects stress.
