Polyploidy is a widespread phenomenon among higher plants and a major factor shaping the structure and evolution of plant genomes. The important ornamental chrysanthemum (Chrysanthemum indicum hybrid) possesses a hexaploid genome with 54 chromosomes and was classified based on its evolutionary origin and cytological methods as an allopolyploid. However, it is questionable whether cytological me...

The diverse plasticity of plant architecture is largely determined by shoot branching. Shoot branching is an event regulated by multiple environmental, developmental and hormonal stimuli through triggering lateral bud response. After perceiving these signals, the lateral buds will respond and make a decision on whether to grow out. TCP transcriptional factors, BRC1/TB1/FC1, were previously prov...

The early wilting and yellowing of leaves in response to ethylene is the main limitation affecting vase quality cut chrysanthemums. Therefore, leaf senescence most difficult problem post-harvest production Nevertheless, molecular mechanism on regulation chrysanthemum still unclear. In this study, we identified an ethylene-sensitive ‘FenDante,’ which showed rapid chlorophyll content decrease und...

Varieties of the economically important ornamental species chrysanthemum have been bred to fit a number of market niches, but the genetic basis and evolutionary relationships among various cultivated types are poorly understood. Here, a DNA marker-based analysis of 199 chrysanthemum entries representing each of the five cultivated types is presented. A set of >90,000 single nucleotide polymorph...

Flos Chrysanthemi, dried flower of Chrysanthemum morifolium Ramat, has drawn much attention recently owing to its potential beneficial health effects for human. Flos Chrysanthemi products are usually taken orally and metabolized by intestinal microflora. However, there has been no investigation of the comprehensive metabolic profile of the Flos Chrysanthemi extract by intestinal flora owing to ...
