Heterosis, also known as hybrid vigour, is widespread in plants and animals, but the
molecular bases for this phenomenon remain elusive. Recent studies in hybrids and …

plants.•Ploidy and intergenomic hybridization induce genetic and epigenetic changes.•DNA …

Polyploidy is a common event in plants that involves the acquisition of more than two
complete sets of chromosomes. Allopolyploidy originates from interspecies hybrids while …

Polyploidy, the possession of more than 2 complete genomes, is a major force in plant
evolution known to affect the genetic and genomic constitution and the phenotype of an …

Background Polyploidy provides new genetic material that facilitates evolutionary novelty,
species adaptation, and crop domestication. Polyploidy often leads to an increase in cell or …

Heterosis is a common biological phenomenon in nature. It substantially contributes to the
biomass yield and grain yield of plants. Moreover, this phenomenon results in high …

Plant hybrids are extensively used in agriculture to deliver increases in yields, yet the
molecular basis of their superior performance (heterosis) is not well understood. Our …

Whole genome duplication (autopolyploidy) is common in many plant species and often
leads to better adaptation to adverse environmental conditions. However, little is known …

Heterosis has been widely used in agriculture, but the molecular mechanism for this remains
largely elusive. In Arabidopsis hybrids and allopolyploids, increased photosynthetic and …

Triploid plants have larger organs, greater biomass, and strong stress resistance by
preserving relatively larger amounts of photosynthetic energy. The undesirable spread of …
