‘Genomic design’ refers to the structural organization of gene sequences. Recently, the role of intron sequences for gene regulation is being better understood. Further, introns possess high rates of polymorphism that are considered as the major source for speciation. In molecular breeding, the length of gene‐specific introns is recognized as a tool to discriminate genotypes with diverse traits of agronomic interest. ‘Economy selection’ and ‘time‐economy selection’ have been proposed as models for explaining why highly expressed genes typically contain small introns. However, in contrast to these theories, plant‐specific selection reveals that highly expressed genes contain introns that are large. In the presented research, ‘wet’Aox gene identification from grapevine is advanced by a bioinformatics approach to study the species‐specific organization of Aox gene structures in relation to available expressed …
