Y a t-il des gens qui ont réussi à faire fleurir des lotus (nelumbo) en Finistère ou terre très très océanique (ensoleillement capricieux) ?
Je n'abandonne pas mes rêves !

Has anyone managed to grow and bloom lotus flowers (Nelumbo) in Finistère or in a very oceanic climate (with unpredictable sunshine)?

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.

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.
