Lotus (Nelumbo) is a basal eudicot with agricultural and horticultural value. It is a worldwide aquatic ornamental belonging to the Nelmbonaceae family with only two species, N. lutea with yellow flowers and N. nucifera with red or white flowers. Although it is the most important trait in ornamental lotus, the genetic mechanism underlying the flower color difference in Nelumbo has not been fully characterized.
Cis-and trans-#regulatory variants affect #flower color differentiation between #lotus species

Gene expression rewiring often contributes to phenotypic evolution between newly diverged species. Changes in gene expression patterns can be caused by mutations in either cis-regulatory regions (promoter) of the gene itself or trans-acting regulatory genes (transcription factors). However, the effects of cis-and trans-regulatory variants at the whole genome level of gene expression leading to phenotypic differentiation in floral organs during the closely related newly diverged species are not very clear.
